Houston-based Prana Surgical will soon bring a new electrosurgical tool to operating rooms around the country. The Prana System officially cleared U.S. Food and Drug Administration (FDA) approval earlier this month.

"Receiving FDA clearance for the Prana System represents a defining milestone for our company," Joanna Nathan, CEO and co-founder of Prana Surgical, said in a news release. "Surgeons today are increasingly focused on achieving precise outcomes while minimizing disruption to healthy tissue. The Prana System was designed to support that shift by integrating targeting and excision into a single, streamlined tool."

Prana Surgical began as Prana Thoracic in 2022. Back then, the company primarily focused on developing screening tools for lung cancer diagnosis. It raised $6 million in series A funding rounds in 2023 and 2024 before transitioning to broader surgical needs in 2025.

The Prana System is a minimally invasive, image-guided, single-use tissue extraction tool designed to retrieve samples without damaging healthy tissue. The tool is still designed with the respiratory system in mind, helping Prana in the fight against lung cancer and other thoracic diseases.

Reducing the impact of tissue extraction via electrosurgery and enhanced image scanning can significantly reduce complications. The Prana System combines localization and tissue-cutting capabilities in one, which keeps surgeons from having to swap out components during a procedure, making for a smoother process. It can core, cut and feel blood vessels on the way toward the intended target, giving surgeons greater control over tissue preservation.

"Electrosurgery is foundational to modern surgery, but there is still opportunity to improve how energy-based tools are applied in minimally invasive settings," Nathan added. "Our goal is to introduce a new class of image-guided surgical tools that enable more precise intervention across a range of procedures."

The company projects the market size for lung nodules to be $7.5 billion in the United States, estimating that 2.5 million nodules will be able to benefit from the new tool. While starting out focused on biopsies, the company plans to evolve the system into other procedures, such as ablation, in the future. It is also planning for a controlled U.S. clinical rollout as it moves toward commercialization

Houston medtech startup secures additional $3M for lung cancer diagnostic tool

fresh funding

A Houston-based medtech startup with an innovative tool that's aiming to transform lung cancer intervention has closed its series A extension round.

Prana Thoracic announced an additional $3 million in funding, a raise that was oversubscribed by 30 percent, reports the company. The company's series A originally closed in March 2023 at $3 million. In August of 2022, the company secured $3 million in grant funding.

"We are grateful for the overwhelming support from our investors in this financing round. Their confidence in our mission and plan is motivating,” Joanna Nathan, CEO and co-founder of Prana Thoracic, says in a news release. “This additional funding will enable us to accelerate our efforts in bringing precision surgical solutions to lung cancer patients worldwide.”

The extension included participation from new investors, including cultivate(MD), GenHenn Capital, and Houston Angel Network, as well as from prior lead investor New World Angels. Existing investors — Johnson & Johnson Development Corp, Texas Medical Center Venture Fund, and the Cancer Prevention & Research Institute of Texas (CPRIT) — also support the company.

"We are excited to support Prana Thoracic in their mission to improve lung cancer treatment. Their innovative approach has the potential to significantly impact patient outcomes," says Dr. R. Sean Churchill, managing director of cultivate(MD), in the release.

The additional funding will support the company as it advances through its clinical and regulatory plans.

“The team has made remarkable progress in developing this novel and minimally invasive technique for lung tissue excision, which has the potential to transform the diagnosis and treatment of early-stage lung cancer," adds Dr. Edward M. Boyle, founder and director at the company. "Beyond lung applications, they are pioneering new methods to use this technology for other soft tissues and are actively exploring integration with ablation and robotic systems, aligning with the future direction of these fields."

In 2022, Nathan joined the Houston Innovators Podcast to discuss her passion for Prana Thoracic's innovation. Listen to the episode below.

Joanna Nathan has been busy. It's been just under six months since the launch of her company, Prana Thoracic, a Houston health tech startup tackling lung cancer diagnostics, and the company has already secured its next round of investment funding. A medical device company developing a tool for early interception of lung cancer, the company announced last week that it closed a $3 million series A financing round.

In August, the company received a $3 million award from the Cancer Prevention & Research Institute of Texas. All of Prana Thoracic's funding is being used to develop the unique diagnostic product and the company's path to first-in-human clinical studies.

“Our technology provides a definitive answer to patients with lung nodules and allows physicians to intervene earlier in the lung cancer patient’s journey,” says Joanna Nathan, CEO, and co-founder of Prana, in a news release. “Our team is grateful to have the support of our investors and excited to leverage this financing to accelerate our technology to the bedside.” Read more.

A new mobile software platform has launched in Houston and is currently looking for restaurants interested in utilizing their technology to upgrade their eatery with mobile ordering at no cost to the restaurant.

Alfredo Arvide, co-founder and managing director of Cloche, tells InnovationMap that the idea for the platform came after the pandemic forced restaurateurs to quickly pivot to touch-free menus. Now that the consumer has adapted to scanning QR codes to view menus, the next step is to optimize ordering — something that will also help with the labor shortages that restaurants are now facing.

"Now is the time transform this industry by creating a better meal experience for the consumers, an easier job for the restaurant staff and a more efficient, more profitable business for restaurant owners," Arvide says. Read more.Read more.

Houston health tech company closes $3M series A

money moves

It's been just under six months since the launch of Prana Thoracic, a Houston health tech startup tackling lung cancer diagnostics, and the company has already secured its next round of investment funding.

Prana Thoracic, a medical device company developing a tool for early interception of lung cancer, announced last week that it closed a $3 million series A financing round led by Florida-based New World Angels with participation from Johnson & Johnson Innovation – JJDC, Inc., Texas Medical Center Venture Fund, and the University City Science Center’s Phase 1 Ventures.

In August, the company received a $3 million award from the Cancer Prevention & Research Institute of Texas. All of Prana Thoracic's funding is being used to develop the unique diagnostic product and the company's path to first-in-human clinical studies.

“Our technology provides a definitive answer to patients with lung nodules and allows physicians to intervene earlier in the lung cancer patient’s journey,” says Joanna Nathan, CEO, and co-founder of Prana, in a news release. “Our team is grateful to have the support of our investors and excited to leverage this financing to accelerate our technology to the bedside.”

The company's technology is a minimally invasive, tissue-sparing nodulectomy tool that can evaluate suspicious pulmonary nodules early on in hopes of being able to catch and treat patients with lung cancer. The tool's development originated on the grounds of the Texas Medical Center in collaboration with Precision Thoracic Corp.

“Prana’s cutting-edge technology was developed on the TMC campus, and we are excited to continue to support Prana in meeting its next milestone through funding from the TMC Venture Fund. The technology they are spearheading could be a game changer in how physicians detect and treat lung cancer. Congratulations to the team on this exciting announcement,” says William McKeon, president and CEO of the Texas Medical Center, in the release.

Micheal Haimour, director of New World Angels, has joined Prana as a board member.

“We are delighted to support CEO Joanna Nathan and her team at Prana as they seek to develop solutions for the early detection and intervention of lung cancer,” he says in the release

Since the company emerged from stealth last summer, Prana has added a few feathers to its cap as a startup. In November, Nathan pitched and won first place at Ignite Healthcare Network’s annual Fire Pitch Competition. Prana was also named a finalist in the Female-Founded Businesses category of the Houston Innovation Awards. Currently, Prana is a member of the Spring 2023 cohort of the TMCi HealthTech Accelerator.

Houston health tech startup wins female-focused pitch competition

women in health care

For the fourth year, a Houston-based, female-focused health tech organization has spotlighted the industry's emerging technology entrepreneurs.

Earlier this month, Ignite Healthcare Network’s Accelerator Program hosted its seven women-led digital health startup finalists, narrowed down from over 330 startups, at its annual Fire Pitch Competition. The nonprofit is led by a group of women executives committed to shaping the future of health care.

“The fourth year of Ignite Health’s Accelerator Program has proved to attract more and more women founders of digital tech and med device startups from around the world,” says Ayse McCracken, Ignite's founder, in a news release.

According to McCracken, 22 applicants made it into the program, which launched earlier this year. A group of judges narrowed down that group to seven finalists, before announcing the top three companies for the competition.

Joanna Nathan, CEO of Houston-based Prana Thoracic, won the top award for her company. Stephanie Gravenor, founder of Denver-based Medecipher, and Liane Clamen, founder of Chestnut Hill, Massachusetts-based Adaptilens, won second and third, respectively.

The event doled out over $500,000 in total. Jay Goss, general partner of Wavemaker Three-Sixty Health, announced $100,000 investments into four finalists' companies. The finalists receiving this award are:

  • Pamela Bonnett, CEO of Denver-based Ultrasound AI
  • Christine Lum Lung, co-founder and CEO of Fort Collins, Colorado-based Origin Healthcare
  • Pamela Singh, co-founder and CEO of Houston-based CaseCTRL
  • Stephanie Gravenor, founder and CEO of Denver-based Medecipher

The partner organizations participating in this year's accelerator and event included Houston Methodist, Memorial Hermann Health System, Texas Children’s Hospital, Texas Children’s Pediatrics, The Menninger Clinic, HCA, Kindred Healthcare, Aetna, Texas Health Resources, Cook Children’s Hospital, TMC, Golden Seeds, Wavemaker 360 Health, Portfolia, Prosalus, 7Wire, Texas Halo Fund, Unity Point Ventures, and others.

“We are grateful for the support and generosity of our sponsors for helping to make this event possible,” says Cheryl Stavins, Ignite board member and co-chair of the event, in the news release. “Their support and involvement continue to ignite our mission and passion to ensure the success and recognition of women entrepreneurs in healthcare.”

Earlier in the day, Ignite Health hosted a new event called “Women Shaping the Future of Healthcare Luncheon." Eighty female executives, investors, founders, and community leaders gathered to hear from three of Ignite Health’s alumni founders: Somer Baburek, CEO of Hera Biotech, Dr. Liz Clayborne, CEO of Nasaclip, and Amanda Gorman, chief clinical officer of Nest Collaborative.

Overheard: Houston-based BIPOC, female founder finalists of 2022 share challenges overcome

eavesdropping at the houston innovation awards gala

Houston is often lauded as one of the most diverse cities in America, and that diversity is seen across its business communities as well, which includes its innovation ecosystem.

Some of the BIPOC-Founded and Female-Founded Business category finalists from the Houston Innovation Awards Gala, which will be held on November 9, shared some of the challenges they faced being in the minority of their industries and careers.

"The biggest challenge I've faced as a female BIPOC founder is having to work 2 to 4 times harder to convince individuals that I am an expert in my field, and that I know what I'm talking about when it comes to my technology and implementation."

— Asma Mirza, CEO and co-founder of Steradian Technologies. "The way I overcame it was by showing irrefutable data to support my expertise and our invention, as well as hiring a diverse team that could substantiate our claims," she adds.

"As a female founder, I used to think that I was looked at as 'less than,' compared to my male counterparts. While I still struggle with this feeling,...  I decided that the biggest hinderance in my confidence as a female founder was the lies that I was telling myself."

— Megan Eddings, founder of Accel Unite. "I felt — and still sometimes do — insecure in a room filled with male founders, not because I thought I was any less-than, but because I was thinking they thought I was less-than — before ever even meeting me," Eddings added, sharing how she tries to change her own perspective. "I now feel a responsibility to share my story, as to show other women that they are not alone, their voice matters and to keep going."

"As a BIPOC founder, it was not easy in the beginning to find the connections and network with folks that had the resources to help us with our aspirations. That was the biggest challenge in getting started."

Photo courtesy

— Enrique Carro, CEO of Blue People. "Now that we have a few clients and testimonials, we are able to pull on them to help us find new clients and connections," he continues. "But this was something that we had to really work hard on at the beginning."

"One of my fears going into the fundraising process was being seen as too weak or too fragile to lead an early-stage venture."

— Joanna Nathan, CEO of Prana Thoracic, who shares she feels this way following the loss of her son. "I found that in being transparent with potential investors, after building some trust, and speaking openly about my loss and how it has inspired me to build this company, I was able to overcome this fear."

"The biggest challenge I’ve faced as a female founder comes down to resources. Finding the capital and time to get everything done is difficult for female founders because we have a lot on our shoulders and there are systemic inequalities that make things even more difficult."

— Allie Danziger, founder and CEO of Ampersand. "I’m creating a billion dollar company, but I’m a mom of two young girls, the executive director of one nonprofit and a board member of another, and a dependable friend, wife, daughter, sister and niece, too," she continues. "Other female founders and VCs are stretched, too, so it can be difficult to connect and find time to figure it out together. I have been very fortunate and also worked really hard to find both the time and resources to make it all work."

Houston-based Fervo Energy bumps up IPO target to $1.82 billion

IPO update

Houston-based geothermal power company Fervo Energy is now eyeing an IPO that would raise $1.75 billion to $1.82 billion, up from the previous target of $1.33 billion.

In paperwork filed Monday, May 11 with the U.S. Securities and Exchange Commission, Fervo says it plans to sell 70 million shares of Class A common stock at $25 to $26 per share.

In addition, Fervo expects to grant underwriters 30-day options to buy up to 8.33 million additional shares of Class A common stock. This could raise nearly $200 million.

When it announced the IPO on May 4, Fervo aimed to sell 55.56 million shares at $21 to $24 per share, which would have raised $1.17 billion to $1.33 billion. The initial valuation target was $6.5 billion.

A date for the IPO hasn’t been scheduled. Fervo’s stock will be listed on Nasdaq under the ticker symbol FRVO.

Fervo, founded in 2017, has attracted about $1.5 billion in funding from investors such as Bill Gates-founded Breakthrough Energy Ventures, Google, Mitsubishi Heavy Industries, Devon Energy (which is moving its headquarters to Houston), Tesla co-founder JB Straubel, CalSTRS, Liberty Mutual Investments, AllianceBernstein, JPMorgan, Bank of America and Sumitomo Mitsui Trust Bank.

Fervo’s marquee project is Cape Station in Beaver County, Utah, the world’s largest EGS (enhanced geothermal system) project. The first phase will deliver 100 megawatts of baseload clean power, with the second phase adding another 400 megawatts. The site can accommodate 2 gigawatts of geothermal energy. Fervo holds more than 595,000 leased acres for potential expansion.

Cape Station has secured power purchase agreements for the entire 500-megawatt capacity. Customers include Houston-based Shell Energy North America and Southern California Edison.

Texas university's new flight academy opens at Houston Spaceport

cleared for takeoff

The vehicles may not have “student driver” stickers on them, but Texas Southern University has moved a dozen planes into its new training facility at the Houston Spaceport, opening the way for student flyers to use the facility.

TSU previously reached a deal with Houston Airports and the City of Houston in 2023 to house its prospective Flight Academy at Ellington Field. At the time, TSU had a small fleet of nine planes for student use, but a $5.5 million investment from the city greatly expanded the space available.

The Flight Academy includes a 20,000-square-foot hangar that serves as a TSU satellite campus. The school now has a fleet of 12 Cirrus SR20 aircraft that were acquired last year through state and alumni funding. An additional 4,500 square feet is used as classroom and office space. An 8,000-gallon fuel tank will support flight training operations.

TSU first launched its Aviation Science Management program in 1986 and added a professional pilot program in 2016. The school is now part of the United Airlines pipeline program and has also forged relationships with Delta and Southwest.

“I want to commend Texas Southern University and Houston Airports for their leadership and partnership in advancing aviation education right here in our city,” Houston City Councilwoman Dr. Carolyn Evans-Shabazz in a press release.

“It connects our students to high-paying, high-demand careers in aviation and aerospace. This is how we grow a city in the right way—by investing in workforce development, aligning education with industry and making sure our residents are prepared to lead in the industries of tomorrow. Houston is already a global leader in aerospace and projects like this strengthen that position even further, especially here at Ellington, where innovation and opportunity continue to take flight.”

The City of Houston signed an agreement to continue funding the academy for five years.

Amazon launches ultrafast, 30-minute delivery service across Houston

Amazon Now

More than 20 years after it redefined fast shipping, Amazon is preparing to raise the bar on consumer expectations again by offering to fulfill customers' most urgent product needs in Houston and other parts of the world in a half-hour or less for an extra fee.

The company, which revolutionized online shopping in 2005 with two-day deliveries for Prime members, is rapidly opening small order-processing hubs in dozens of U.S. and foreign cities to cater to shoppers who can't or don't want to wait for cough medicine to relieve flu symptoms or tomatoes for tonight's dinner salad.

The ultrafast service, called Amazon Now, first launched in India last June. Amazon says 30-minute deliveries now are also available in urban areas of the United States, Brazil, Mexico, Japan, the United Arab Emirates, the United Kingdom.

The mini-warehouses devoted to Amazon Now are about the size of a CVS drugstore. They stock about 3,500 products for expedited delivery, including beer, diapers, pet food, meat, nonprescription medications, playing cards and cellphone charging cables.

“We know that customers love speed and always have,” Beryl Tomay, Amazon’s head of transportation, told The Associated Press on Monday. “What we see customers doing, when we offer faster speeds, are they purchase more from Amazon. And Amazon becomes more top of mind for that or other types of items as well.”

In the U.S., the company first tested Amazon Now in Seattle, the home of its headquarters, and in Philadelphia. Most residents of the Dallas-Fort Worth area and Atlanta now have access as well. The service is also live in Dallas-Fort Worth, Denver, Minneapolis, Phoenix, Oklahoma City, Orlando, and dozens of other cities, Amazon said, with New York City and others expected by year-end.

The service charges for Amazon Now start at $3.99 for Prime members, who pay an annual fee of $139, and $13.99 for non-members. A $1.99 small basket fee applies to orders under $15, Amazon said.

The company's bet on a need for speed also comes as some consumers are rebelling against rushed deliveries as they weigh the potential impact on the environment and the workers tasked with preparing orders at a rapid rate.

Amazon’s approach
A relentless focus on speed helped Amazon build a logistics and e-commerce empire. After it made two days the new delivery time normal, Amazon moved into one-day and same-day deliveries for its Prime members. This spring, the company began making 90,000 products available in one hour or three hours at an extra cost.

The scaled down and sped up microhubs that are designed to handle 30-minute orders represent another step in Amazon's pursuit.

Only a handful of people prepare orders from aisles of shelves in the 5,000- to 10,000-square-foot facilities, unlike the sprawling fulfillment centers storing millions of items where Amazon employs a mix of human workers and robotics to pick and pack orders.

Amazon tailors the product inventory to each location and uses artificial intelligence and other technology to analyze what customers buy, as well as when and how often. The most popular U.S. purchases so far include soap, toothpaste, mouthwash, toilet plungers, bananas, limes and wireless earbuds, Amazon said.

The competition
Amazon’s attempt to up the instant gratification ante provides direct competition to on-demand food delivery platforms like Instacart, Uber Eats, DoorDash and Grubhub, which don't have the scale of the e-commerce titan, according to independent retail analyst Bruce Winder.

“What Amazon brings is their prowess in supply chain,” Winder said.

These smaller companies said they don't see Amazon as a threat, though, citing the hundreds of thousands of items they are able to deliver to users' doorsteps by partnering with various merchants and restaurants.

“DoorDash has a mission to empower grocers and retailers and augment their existing footprint, not to replace them,” DoorDash spokesperson Ali Musa said in an emailed statement. “We win only when they win, which is how we can offer over half a million grocery and retail items in under an hour across the country.”

Amazon also is in a race with Walmart to become the retailer that reliably gets orders to online shoppers in under an hour.

For an additional $10 on top of standard delivery charges, shoppers can place Walmart Express Delivery orders from among more than 100,000 products that are guaranteed to arrive in an hour. Many customers, however, are receiving the items under 30 minutes, Walmart CEO John Furner told analysts in February.

Domino's cautionary tale
Companies have promised deliveries in 30 minutes or less before, but the landscape also is littered with failed attempts to break the speed barrier.

The COVID-19 pandemic produced a flurry of companies that promised 10- to 15-minute grocery deliveries from microwarehouses in dense neighborhoods, according to Sucharita Kodali, an analyst at market research firm Forrester Research.

But soaring operating costs, low customer loyalty and the drying up of investor money ultimately caused most to fail before the pandemic was over, analysts said.

Domino’s in 1984 pushed a guarantee that customers would receive their pizzas for free if they weren't delivered in under a half-hour. The company amended the “30 minutes or it’s free” policy after two years, providing only a $3 discount for late deliveries.

The promotion helped Domino’s win market share, but it ended up tarnishing the company's reputation. It dropped the guarantee in December 1993 after a string of crashes and lawsuits involving drivers racing to meet the deadline.

Brad Jashinsky, a retail analyst at information technology research and consulting firm Gartner, said he thinks Amazon should take the pizza chain's experience as a cautionary tale.

“You get in trouble when you start overpromising something like that,” he said.

Amazon won't be making any time guarantees and instead plans to keep customers who chose the 30-minute delivery option updated on the progress of their orders, Tomay said.

“There's no rushing either in our building workers or the gig workers,” she said.

Taking it slow
Kodali thinks Amazon will need a lot of people placing orders around the same time from the same or adjacent apartment buildings for the 30-minute service to be cost-effective.

Consumers may appreciate rapid receipt of products like toilet paper and batteries, but retailers and logistics experts said they also see some online shoppers, especially members of Generation Z, choosing no-rush shipping for products they don't need in a hurry.

Amazon for several years has invited customers to skip one- or two-day delivery and to receive their orders on the same day in as few parcels as possible. Consolidating orders into fewer packages by electing to have them delivered at the same time cuts down on boxes, shipping envelopes and fuel use, analysts said.

“The millennials who came to age in an era that was on fast delivery came to expect it de facto, whereas ... Gen Z is more accepting of a slower speed than previous generations before them,” said Darby Meegan, a general manager at Flexport, a supply chain and logistics company that fulfills orders for thousands of online merchants.

Still, Amazon executives have cited positive early results for Amazon Now in India, where they said Prime members tripled their requests for 30-minute deliveries once they started using the service.

Amazon Now also is attracting more repeat American customers, Tomay said.

“It’s in early days and time will tell,” she said. “I think that it will be interesting to see how it evolves.”
