Rice Business Plan Competition doles out $2M to 2025 student teams

big winners

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 nonprofit news outlet will shut down after only 2 years

In the News

Amid financial challenges, the nonprofit Houston Landing online news outlet plans to shut down by mid-May.

In an April 15 announcement posted on its website, Houston Landing says that although it launched in 2023 with more than $20 million in seed funding, the outlet failed to attract enough revenue to continue operating. The announcement followed a vote by the organization’s board of directors to close the nonprofit newsroom. All 43 employees will be laid off, the Columbia Journalism Reviewreports.

“We are proud of the Landing’s coverage of Greater Houston and continue to believe deeply in the need for more free, independent journalism in our region,” Ann B. Stern, board chair of Houston Landing as well as president and CEO of the Houston Endowment, says in the announcement. “This decision was difficult but necessary. Houston Landing’s reporting has made a meaningful impact in the community, but it struggled to find its long-term financial footing.”

According to the announcement, the Landing’s board is exploring a partnership with the Austin-based Texas Tribune, a pioneer in nonprofit journalism, to potentially establish a local news initiative in Houston. Later this year, the Texas Tribune plans to open a locally focused newsroom in Waco. A similar newsroom is in the works in Austin.

“We have great respect for Houston Landing’s work in delivering high-quality, nonpartisan journalism to its readers,” says Sonal Shah, CEO of the Texas Tribune. “We also understand the profound challenges facing local newsrooms today — journalism is a public service and needs a strong ecosystem to thrive. We look forward to exploring how we can learn from what the Landing started and create a sustainable model that serves the Houston community. We will take time to explore the right path forward to ensure sustainability.”

Houston Landing was launched after a two-year study led by the American Journalism Project found many Houstonians were disappointed about a lack of trustworthy, deeply reported local news. Financial backers of the Landing include the American Journalism Project, the Houston Endowment, Arnold Ventures, the Kinder Foundation, and the John S. and James L. Knight Foundation.

Despite the high-profile support, the site struggled to find an audience. CJR notes that the Landing had approximately 13,000 newsletter subscribers and only generated about $80,000 in subscription revenue. In the article, executive editor Sewell Chan identifies a number of other issues, including a lack of editorial focus and changes in leadership. “But in the end, the gap between board and staff, between management and labor, and between runway and revenue was just too large to bridge,” he writes.

“While it’s with a heavy heart that we announce the closure of our newsroom, I want to express my deepest gratitude to the dedicated journalists and staff members who poured their passion into our mission every single day,” Houston Landing CEO Peter Bhatia says.

“Houston Landing demonstrates how a commitment to truth and accountability can transform communities and improve lives,” he adds. “I’m thankful to those who believed in us, supported us, and stood with us as we connected with each other through stories that inspired positive change.”

Houston space tech company develops new engine features with NASA funding

testing 1, 2, 3

Outfitted with a new type of aerospace technology, a rocket engine developed by Houston startup Venus Aerospace for hypersonic flights will undergo testing this summer.

Supported by a $155,908 federal Small Business Innovation Research (SBIR) grant from NASA, Venus Aerospace came up with a new design for nozzles — engine parts that help manage power — for its compact rocket engine. Venus Aerospace says the newly configured nozzles have “exceeded expectations” and will be incorporated into Venus’ upcoming ground-based engine testing.

“We’ve already proven our engine outperforms traditional systems on both efficiency and size,” Venus Aerospace CEO Sassie Duggleby says. “The technology we developed with NASA’s support will now be part of our integrated engine platform — bringing us one step closer to proving that efficient, compact, and affordable hypersonic flight can be scaled.”

The engine at the heart of Venus’ flight platform is called a rotating detonation rocket engine (RDRE). Venus says it’s the first U.S. company to make a scalable, affordable, flight-ready RDRE.

Unlike conventional rocket engines, Venus’ RDRE operates through supersonic shockwaves, called detonations, that generate more power with less fuel.

“This is just the beginning of what can be achieved with Venus propulsion technology,” says Andrew Duggleby, chief technology officer at Venus, founded in 2020. “We’ve built a compact high-performance system that unlocks speed, range, and agility across aerospace, defense, and many other applications. And we’re confident in its readiness for flight.”

Last fall, the company unveiled a high-speed engine system that enables takeoff, acceleration, and hypersonic cruising — all powered by a single engine. While most high-speed systems require multiple engines to operate at different speeds, Venus’ innovation does away with the cost, weight and complexity of traditional propulsion technology.

Among other applications, the Venus system supports:

Spacecraft landers
Low-earth-orbit satellites
Vehicles that haul space cargo
Hypersonic drones and missiles
