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

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.

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.

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."

Photo courtesy

— 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."

3 fast-growing Houston scaleups named Innovation Awards finalists

meet the finalists

From IPOs to groundbreakings, some of Houston's most innovative companies reached major milestones this year.

As part of the 2026 Houston Innovation Awards, our Scaleup of the Year category honors innovative later-stage startups that have recently reached a significant milestone in company growth. Three scaleups have been named finalists for the 2026 award.

Read more about these businesses, their founders and their breakthrough technologies below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Erock

Energy infrastructure company Erock, previously known as Enchanted Rock, develops dual-purpose microgrids that rely on natural gas and renewable natural gas to produce lower carbon emissions and air pollutants than diesel generators. Its products can provide bridge power before grid interconnection, backup power during outages and dispatchable capacity that supports long-term grid reliability. The company has more than 1,100 megawatts of installed capacity and over 20 years of experience serving commercial, municipal and large-scale technology customers.

Erock completed its initial public offering this year, raising approximately $600 million in gross proceeds. It also grew its contracted power system sales backlog to approximately $1.7 billion, up tenfold year-over-year, with production sold out through 2028, according to the company's application. The company secured a major equipment order from Anthropic, began construction of the 366-megawatt El Paso Electric project supporting Meta's data center campus, and started assembly operations at its Hyperion facility in Cypress, Texas.

Hertha Metals

Hertha Metals produces lower-cost, lower-emission steel and high-purity iron. The company has developed a single-step process that uses natural gas as a direct reductant instead of metallurgical coal, which cuts production costs by more than 25 percent and emissions by up to 50 percent, according to the company. The same process produces high-purity iron needed for high-purity steels and rare earth magnets. The company says it aims to "re-industrialize America’s production of critical materials."

Hertha Metals was founded by CEO Laureen Meroueh in 2022 and emerged from stealth last year with more than $17 million in venture capital funding. The company closed a $133.65 million Series A this month and also broke ground on its $100M high-purity iron factory known as Chalyx in Conroe.

Venus Aerospace

Spacetech company Venus Aerospace is developing a high-thrust rotating detonation rocket engine (RDRE) that replaces the subsonic combustion used in conventional rocket engines. The RDRE is a compact, simpler engine that can deliver up to 15 percent greater efficiency for defense and space applications. It completed its first U.S. flight test of the engine last summer.

Venus Aerospace was founded in 2020 by CEO Cassie Duggleby and CTO Andrew Duggleby. It raised a $20 million Series A in 2022 and $42 million Series A2 in 2025. It closed a $91 million Series B earlier this year and expanded its leadership team. The company is working toward longer-duration and higher-thrust testing and advancing its flight program.
