Celebrating its 25th year, the Rice Alliance for Technology and Entrepreneurship hosted the celebrated Rice Business Plan Competition this month, doling out more than $2 million in investment and cash prizes to the top-performing teams.

“For 25 years, the Rice Business Plan Competition has helped shape how Rice Business shows up in the world by creating a platform where student-entrepreneurs can tackle some of the most complex challenges of our time in energy, in health care, in technology and beyond,” Peter Rodriguez, dean of Rice Business, the presenting sponsor of the event, said in a news release. “If we’re serious about changing the world — and I believe we are — then it’s our responsibility to open doors for students everywhere to imagine bold solutions and build what comes next.”

Over the course of the three-day event, the 42 startups competing this year from colleges or universities around the world presented their plans before more than 300 angel, venture capital, and corporate investors. The teams were selected from the event’s largest applicant pool to date and represented 34 universities across four countries, according to Rice. Winners were announced at the company showcase and awards ceremony April 12 in downtown Houston.

Seven finalists were selected, though each team left the competition with some form of funding, according to Rice. The University of Michigan's Intero Biosystems was the star of the show, bringing home both the top-place finish and the largest total investment. Rice's own Pattern Materials also had a strong showing, placing fourth in the pitch competition and also earning the fourth-highest investment total.

Houston expert examines the importance of early-stage investors in the innovation ecosystem

guest column

In a flourishing startup ecosystem, the roles of entrepreneurs, venture capitalists, startup development organizations, policymakers, research institutions, and universities are well documented and understood. Less obvious, however, is the role of early-stage investors, aka, “angel investors.”

These unique people are often the first non-family money to invest in a young company, often while it is still refining its business model, completing its minimum viable product (MVP), or finding product-market fit. Excellent angel investors, however, provide value to the ecosystem far beyond their ability to write a check.

Most angel investors bring deep expertise within their domain. These can be 20- or 30-year industry veterans with invaluable been-there-done-that experience in a particular technology, discipline, vertical, or regulatory environment. They can share insights learned from various industry trends that have succeeded and failed, which often save startups significant time and effort. Or they may bring complementary business expertise such as legal, accounting, technology, financing, or startup strategy. Many angels have launched or worked in multiple startups themselves, which gives them an ability to quickly understand and assist with the unique challenges of early-stage business.

Additionally, good investors are aggregators of knowledge. They constantly read about the sectors in which they invest, learn the latest trends, and watch for innovations that they believe will change industries. As forward thinkers, they know how to look past buzzwords to find what is truly unique or different. They often ask the “hard questions” that cut to the heart of the matter. Wise founders learn how to listen and use this feedback to improve their company and strategy.

Many angel investors serve as mentors to startups and share their hard-won knowledge. Most start with informal or unpaid relationships either through an SDO or personal referral. If they form a meaningful connection with a particular startup, this could turn into an official role as a compensated advisor. The best of these relationships are mutually beneficial and ultimately profitable if the company has a successful exit. Similarly, angels may become advisors to venture capital funds that want to bring their insights to their portfolio companies.

Investors are natural connectors in an ecosystem. As they search for, invest in, and mentor great startups, they foster connections across the innovation community. Relationship-building is key to all business success, and a wise angel knows how to respectfully leverage connections for mutual benefit. However, be careful not to ask an investor to share connections too soon. One of the fastest turn-offs is someone who asks me to open my rolodex before earning my trust and respect.

The most obvious benefit that investors bring to the innovation ecosystem is funding for early-stage businesses. This infusion of capital enables young businesses to identify, create, and grow value, which is the ultimate point of innovation. I mention it last, however, because savvy entrepreneurs know the difference between “smart money” and “dumb money.” Dumb money is not a pejorative but a label for money that has no voice or utility beyond its monetary value (which makes it silent or “dumb”).

Smart money, on the other hand, brings many or all of the other attributes discussed above: knowledge, expertise, mentoring, and connections. In terms of value, smart money is worth many times more than its cash value.

As the Houston innovation ecosystem grows, we need more accredited investors with a passion for innovation to learn about angel investing and determine if it is a fit for them. Given its very high-risk profile, it certainly isn’t appropriate for everyone. However, angel investing is a powerful way that investors can help solve society’s biggest challenges and contribute to a thriving innovation community.

Houston startup with next-gen farming tech calls for crowdfunding as it plans to grow

seeing green

Whether it’s on Mars or at the kitchen table, entrepreneur Bart Womack wants to change what and how you eat.

But the CEO and founder of next-generation farming startup Eden Grow Systems is seeking crowdfunders to help feed the venture.

The company evokes images of a garden paradise on earth. But the idea behind the Houston-based NASA spinoff came from a more pragmatic view of the world. Womack’s company sells indoor food towers, self-contained, modular plant growth systems built on years of research by NASA scientists looking for the best way to feed astronauts in space.

The company has launched a $1.24 million regulated crowdfunding campaign to raise the money it needs to scale and expand manufacturing outside the current location in Washington state.

Additionally, the U.S. Air Force recently chose Eden as a food source for the U.S. Space Force base on remote Ascension Island, in the Atlantic Ocean, Womack tells InnovationMap. Another project with Space Center Houston is also in the works.

“We want to be the government and DOD contractor for these kind of next-generation farming systems,” he says.

The Houston-based company includes former NASA scientists, like recent hire Dr. L. Marshall Porterfield, of Purdue University, as an innovation advisor.

Womack, a former digital marketer, Houston public channel show host, night club owner and entertainment entrepreneur, left those ventures in 2012, after the birth of his first child. While taking a year to study trends research, in 2014, what he read intrigued and alarmed him.

“I’ll never forget, I came across a report from Chase Manhattan Bank….of the top 10 disruptive investment sectors, over the next decade,” he says. “At the very top of the list was food.”

His conclusions on the fragility of the world’s food supply system, due to overpopulation, and scarcer land, led him to launch Eden in 2017, funded by venture capital firm SpaceFund, Womack, his family, friends and angel investors.

Womack believes “black swan” events will only increase, disrupting the food supply system and further jeopardizing food supplies.

“We’re going to enter a period of hyper novelty in history,” Womack says.. "The system we’ve built for the last 100 years, the super optimized system, is going to begin to break apart."

To avert a centralized food production outcome, operated by corporate giants like Amazon or Walmart, Womack’s vision offers a decentralized alternative, leaving it in local hands.

With $2 million put into the company so far and a half million-dollars in sales last year, Womack argues that Eden has achieved much and can make food independence within reach for everyday families.

The company commercialized NASA technology to fill what it viewed as “a huge gap within the controlled…agricultural space.”

The tower is the building block of a modular, automated and vertical indoor plant growth system, with calibrated misting, fans, and LED lighting, controlled by an app.

The company website touts the towers as an easy way to grow plants like lettuce, carrots, tomatoes, and potatoes, with little water, no soil, and lots of air, without the expense and work of cultivating an earth-based garden.

For those who want to eat more than greens, the towers provide a way to breed fish and shrimp in an aquaponic version, recycling fish waste as plant fertilizer.

However, big plans come with big costs. The towers range in price from $5,000 to $7,000, although payment plans for those who qualify make it affordable.

Eden has sold around 100 of their towers so far, to a variety of customers. But rising costs and shipping delays have led to a a three-month backlog.

The manufacturing and shipping associated with larger installations means that even if the company made a million-dollar sale, delivery of the product would take a year.

“One of the hardest things…as a start-up, the last couple of years, is trying to narrow down exactly where the biggest payback is,” Womack says. “There is the lower hanging fruit, of small sales to individual buyers, but there’s the larger fruit of institutional buyers. But they can take months and years to convert into an actual buyer.”

Customers include several universities, including Texas A&M University and Prairie View A&M University, and talks are underway with other large academic institutions.

For now, attracting investors so the company can reach its funding goal poses the biggest challenge.

“Texas investors are very, very hard-nosed, and they’re not like West Coast investors. They want to understand exactly how they’re going to get their money back, and exactly how quickly,” he says.

Womack says the crowdfunding round would allow the company to expand manufacturing operations into Houston, deliver product faster, and invest in advertising.

“When we complete this round, and become completely self sufficient, we’re planning on moving to a $25 million valuation,” Womack says. “We can show, given money, we can scale the company.”

The city of Nassau Bay, next to NASA’s Johnson Space Center, has purchased towers and plans to purchase more, not for the production of food, but to grow ornamental flowers.

Womack says that city officials there found that it’s cheaper to grow the decorative plants themselves, rather than buying them.

The towers are adaptable, and can grow not only food but cannabis and other plants, and if buyers want to use them other purposes, that adds to the product’s appeal, Womack says.

Eden has also sold some towers to Harris County Precinct 2 and the city of Houston, as part of a project he says will turn food deserts throughout the area into “food prosperity zones.”

“Our goal is to be the farming equivalent of Boeing,” Womack says.

Investors join forces for citywide alliance to increase access to early-stage capital

Teamwork makes the dream work

Securing funding for your startup is now a one-stop shopping experience. Over 200 accredited investors have teamed up to create the Houston Investment Network Alliance — a platform that promotes investment opportunities and mentorship for early-stage companies.

HINA is a collaboration where participating investors can partner up to co-invest in startups, co-host investor events, and share opportunities.

Behind the alliance are four Houston investment entities: the Houston Angel Network, Rice Angel Network, GOOSE Society of Texas, and Cannon Ventures.

"HAN and the Goose Society have invested over $150M in early stage companies over the last decade. The appetite for startup investing continues to be alive and strong in Houston," says Stephanie Campbell, HAN managing director, in a release. "The birth of new groups like RAN and Cannon Ventures demonstrates a new and growing appetite for investment."

Each of the organizations have connections to Rice University and previously worked together on a sports technology-focused pitch night hosted at The Cannon, a West Houston coworking space lead by CEO and founder, Lawson Gow. Gow is the son of David Gow, owner of InnovationMap's parent company Gow Media.

The Cannon launched its own fund, Cannon Ventures, about seven months ago. It has four startup partners: SEATz, Win-Win, Data Gumbo, and SeeHerWork. Each Cannon Ventures startup partner will received anywhere between $100,000 to $400,000 of seed funding as well as access to space in The Cannon and its accelerator opportunities, Gow says.

Cannon Ventures has already also collaborated with the other HINA organizations. The Rice Angel Network is even based out The Cannon.

"We're increasingly co-investing with other angel networks," Gow says, "because it's hard to start a company and raise money, so the more we can do that to help Houston startups get the money they need."

According to Gow, Houston's thriving startup scene and deep pockets is a perfect opportunity for HINA.

"One of the great things about Houston is we've got a lot of money here," he says. "One of the most transformative things we can do for the startup community is get a lot of high-net worth individuals is get them off the bench and onto the field and activate them as regular angel investors into Houston-based startups. That's a really important goal of Cannon Ventures is to grow our membership base and get ore people involved."

Houston medtech startup clears FDA approval for new surgical tool

precision surgery

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 sales of $7.5 billion from the Prana System in the United States, estimating that 2.5 million surgical modules will be able to use 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

Texas still ranks as No. 1 in U.S. for inbound moves, but growth dips

by the numbers

Texas continues to be the country’s No. 1 magnet for newcomers from other states, giving a boost to the state’s economy. However, Texas’ appeal weakened in 2024 compared with the previous year, due in large part to spiking home prices.

An analysis of U.S. Census Bureau data by self-storage platform StorageCafe shows Texas saw net interstate migration of 76,000 people in 2024. Texas’ net interstate migration dropped nearly 50 percent from 2023, according to the analysis. Net migration refers to the number of incoming residents minus the number of outgoing residents.

California remained the top source of newcomers for Texas, sending nearly 77,000 residents to the Lone Star State in 2024, the analysis says. Florida ranked second, followed by New York, Colorado and Illinois.

“These trends reveal Texas’ continued pull from both high-cost coastal markets and other large Sun Belt states, resulting in a mix of affordability-driven and job-driven relocation,” StorageCafe says.

Putting a damper on the influx of new residents: a roughly 124 percent surge in Texas home prices over the past decade, according to StorageCafe.

“While the state remains significantly more affordable than California, its top feeder state, the once-wide pricing gap has narrowed,” says StorageCafe. “For many movers, Texas is still a relative bargain, but no longer an undisputed one.”

Nonetheless, Texas keeps attracting young, highly educated people, which bodes well for the state’s long-term economic outlook, StorageCafe says. More than half of new arrivals to Texas in 2024 held at least a bachelor’s degree, and the age of newcomers averaged 32.

Where are most of these young, highly educated newcomers settling?

Lloyd Potter, former Texas state demographer, tells StorageCafe that population growth in Texas is happening most rapidly in suburban “ring counties” at the expense of slowing growth in urban cores. Ring counties are on the outskirts of major metro areas.

“Many people are moving from urban cores to suburban rings seeking lower costs, newer housing, better schools, and more space,” Potter says. “Typically, a move to a suburban county will be within commuting or hybrid‑commuting distance of major metro economies.”

Artemis II makes historic call to space station with help from Houston Mission Control

History in the making

Still aglow from their triumphant lunar flyby, the Artemis II astronauts made more history Tuesday, April 7: calling their friends aboard the International Space Station hundreds of thousands of miles away as they headed home from the moon.

It was the first moonship-to-spaceship radio linkup ever. NASA's Apollo crews had no off-the-planet company back in the 1960s and 1970s, the last time humanity set sail for deep space.

"We have been waiting for this like you can’t imagine,” Artemis II commander Reid Wiseman called out.

For Christina Koch on Artemis II and Jessica Meir aboard the space station, it marked a joyous space reunion despite being 230,000 miles (370,000 kilometers) apart. The two teamed up for the world's first all-female spacewalk in 2019 outside the orbiting lab.

Koch told her “astro-sister” that she'd hoped to meet up with her again in space “but I never thought it would be like this — it's amazing.”

“I'm so happy that we are back in space together,” Meir replied, “even if we are a few miles apart.”

Houston's Mission Control arranged the cosmic chitchat between the four lunar travelers and the space station's three NASA and one French residents.

Koch described being awe-struck by not just the beauty of Earth, “but how much blackness there was around it.”

“It just made it even more special. It truly emphasized how alike we are, how the same thing keeps every single person on planet Earth alive,” she told the space station crew. “The specialness and preciousness of that really is emphasized” when viewing the home planet from the moon.

By late Tuesday afternoon, the Artemis II astronauts had beamed back more than 50 gigabytes' worth of pictures and other data from the previous day's lunar rendezvous, which set a new distance record for humanity. The highlight: an Earthset photo reminiscent of Apollo 8's Earthrise shot from 1968.

"While they are inspirational and, I think, allow all of us to really feel a little bit of what they were feeling, there's also a lot of science hidden inside of those images," said Mission Control's lead lunar scientist Kelsey Young. “The conversations and the science lessons learned are just beginning."

During a debriefing with Young, the astronauts recounted how they spotted a cascade of pinpricks of light on the lunar surface from impacting cosmic debris. The flashes lasted mere milliseconds and coincided by chance with Monday evening's total solar eclipse.

Young said it was too soon to know whether the crew witnessed an actual meteor shower or more random, run-of-the-mill micrometeoroid hits. Either way, there were “audible screams of delight” in the science operations center, she said.

Koch described being awe-struck by not just the beauty of Earth, “but how much blackness there was around it.”

“It just made it even more special. It truly emphasized how alike we are, how the same thing keeps every single person on planet Earth alive,” she told the space station crew. “The specialness and preciousness of that really is emphasized” when viewing the home planet from the moon.

The first lunar explorers since Apollo 17 in 1972, Wiseman and his crew are aiming for a splashdown off the San Diego coast on Friday to wrap up the nearly 10-day test flight. The recovery ship USS John P. Murtha left port Tuesday for the target zone.

It sets the stage for next year's Artemis III, a lunar lander docking demo in orbit around Earth. Artemis IV will follow in 2028 with two astronauts attempting to land near the lunar south pole.

As for the Orion capsule’s pesky potty, Mission Control assured the astronauts that no maintenance was required Tuesday. The toilet has been on-and-off limits to the crew ever since last week’s launch, prompting them to rely on a backup bag-and-funnel system for urinating.

NASA Administrator Jared Isaacman told the crew following the lunar flyby Monday night: “We definitely have to fix some of the plumbing” ahead of the next Artemis mission. Engineers suspect a clogged filter in the overboard flushing system.

Aside from the toilet and other relatively minor matters, the mission has gone well, Isaacman noted at a news conference Tuesday, “but I'll breathe easier when we get through reentry and everybody's under chutes and in the water.”
