Houston had a strong showing at this week's SXSW Pitch showcase in Austin, with two local startups claiming top prizes in their respective categories.

Little Place Labs, a Houston space data startup, won the Security, GovTech & Space competition. Clean-tech company Helix Earth, which spun out of Rice University and was incubated at Greentown Labs, won in the Smart Cities, Transportation & Sustainability contest.

As one of SWSX's marquee events, held March 8-10, the pitch competition featured 45 finalists, selected from 589 applicants, in nine categories.

"We faced impressive competition from a well-chosen set of finalists, and we're honored to be chosen as the winners. One of the judges even commented, ‘Who knew you could make air conditioning sexy,’” Brad Husick, Helix's co-founder and chief business officer, said in a release.

Helix Earth was launched in 2022 and is known for its space capsule air filtration system that was co-developed for NASA. The commercial air conditioner add-on technology, now in a pilot phase, has been used to retrofit HVAC systems for commercial buildings and can save up to 50 percent of the net energy, cutting down on emissions and operating costs, according to the company. Its co-founder and CEO Rawand Rasheed was named to the Forbes 30 Under 30 Energy and Green Tech list for 2025.

“This win validates our mission to drive sustainable innovation in commercial air conditioning and beyond. We are excited about the future of Helix Earth and the impact we will have in reducing energy consumption and emissions," Rasheed said in a statement.

Little Place Labs echoed that sentiment with a post on LinkedIn celebrating the win.

"This all started with a simple mission: To deliver real-time space insights to help first responders, mission planners, and decision-makers act before problems arise,” the post read. "Today, that mission feels even stronger."

The company uses advanced AI and machine learning to deliver near-real-time space analytics for both ground and space-based applications. Its software aims to help first responders, mission planners and decision-makers detect anomalies and make informed decisions quickly. It was co-founded in 2020 at Oxford by Houstonian and CEO Bosco Lai and Gaurav Bajaj and participated in the 2023 AWS Space Accelerator.

Tempesst Droneworx, a veteran-owned software company that provides real-time contextual intelligence for early warning detection, took home the Best Speed Pitch prize.

Jesse Martinez, founder of invincible, and Anu Puvvada of KPMG were two judges representing Houston.

According to SXSW, 647 companies have participated in SXSW Pitch over the years, with over 93 percent receiving funding and acquisitions totaling nearly $23.2 billion. See the full list of 2025 winners here.

Houston energy startup wins Ion's annual showcase, pitch competition

1st place

The Ion hosted its annual startup pitch competition, and one company walked away with a win.

WellWorth, a financial modeling and analysis software-as-a-service company for the upstream energy sector, won the Houston Startup Showcase + Expo and secured a $5,000 prize. The startup's technology introduces a more streamlined approach to NAV modeling or corporate financial modeling for its users.

“Having worked in investment banking, I have seen firsthand how the limitations of Excel models and a lack of bespoke tools have led to inefficient workflows in upstream Oil & Gas finance," says Samra Nawaz, CEO and Co-founder of WellWorth, in a statement. "We decided to solve this problem by building a cloud-based platform that helps energy finance leaders improve decision-making around raising, managing, and deploying capital.”

Nawaz explains how impactful the opportunity to pitch has been on WellWorth, which aims to raise funding early next year accelerate customer acquisition and product development.

“By getting involved in the Ion’s innovation ecosystem, we’ve been able to not only network with many entrepreneurs and innovators in the Houston community, but also find opportunities to scale our growth,” continues Nawaz. “We’re thrilled to have brought a few more customers onboard recently, and are working closely with them to optimize our product pipeline."

The company pitched alongside the other five finalists, which included Tierra Climate, MRG Health, BeOne Sports, Trez, and Mallard Bay. Mallard Bay, a booking platform for hunting and fishing trips, secured the people's choice award, which was decided by the crowd.

“Our flagship event, Houston Startup Showcase, not only connects startups and entrepreneurs with top business leaders but also provides them an opportunity to pitch their innovations to the technology ecosystem,” says Jan Odegard, executive director of the Ion, in a news release. “We extend our congratulations to WellWorth and the company’s innovative SaaS platform for energy industry finance teams, as well as Mallard Bay, the People’s Choice winner. These companies are exemplifying the exciting new technologies being developed in Houston today.”

In addition to the pitches, several companies showcased at the event, including Nanotech, manufacturer of thermal management materials for the built environment; last year's winner Unytag, a universal toll tag that provides drivers the ability to pass through tolls anywhere in the nation; and Softeq, provides early-stage innovation, technology business consulting, and full-stack development solutions to enterprise companies and innovative startups.

Axiom Space expands executive team with two C-suite hires

new leaders

Fresh off officially making Texas its legal headquarters, Axiom Space has named two new C-level executives.

The Houston-based spacetech company, which is developing the first commercial space station, announced earlier this month that it had appointed Zach Gitomer as its new chief financial officer and Erick Wegerer as chief information officer.

Gitomer served as vice president of investor relations and capital markets for Axiom from March to June of this year. Before joining Axiom, he held various leadership roles at Bank of America, Merrill Lynch, and Citi, where he supported technology and growth companies, according to Axiom.

"Building era-defining space infrastructure and pioneering the orbital economy is a complex endeavor that requires not just an audacious vision and stellar engineering talent, but the financial infrastructure, discipline, and capital strategy to match," Gitomer shared in a LinkedIn post. "I’m honored to take on this role ... I’m looking forward to partnering with the exceptional leadership team here at Axiom Space during a defining chapter for the company and commercial spaceflight broadly, as well as a crucial period for maintaining U.S. human presence in low-Earth orbit and leadership in space exploration."

Wegerer joins Axiom after most recently serving as CIO of Washington-based Insitu Inc., a subsidiary of Boeing that develops customized unmanned hardware for commercial, government and defense customers.

"My time at Insitu was defined by talented people, meaningful challenges, and work that mattered. I'm grateful for the teams, partners, and leaders who made progress there possible. Stepping into Axiom, I'm energized by the mission, the momentum, and the opportunity to help shape what's next," Wegerer shared.

The duo was celebrated on the floor of the New York Stock Exchange last week.

“We are pleased to welcome these exceptional leaders to the Axiom Space team," Axiom CEO Jonathan Cirtain added in the announcement. “Their strong record of helping complex organizations advance their strategic priorities will strengthen our executive team to further advance our core business objectives."

It's been a busy summer for Axiom. The company tacked on an additional $175 million to a previously announced capital raise, bringing the oversubscribed round to a total of more than $525 million, in June.

It also announced plans to open a Japanese subsidiary July 1. It tapped veteran Japanese astronaut Koichi Wakata to lead Axiom Space Japan as chief technology officer in the Asia-Pacific region. It also shared plans to establish Axiom Space Switzerland, a wholly owned subsidiary based in Lucerne that is also expected to begin operations this summer.

Axiom also officially redomiciled its legal headquarters from Delaware to Texas last month. Read more here.

Houston hardtech accelerator names 8 founders to 2026 cohort

Activate Houston is led by managing director Jeremy Pitts, who co-founded Greentown Labs in Boston. It is based out of the Ion. The latest cohort is Activate Houston's third. Read more about the last year's cohort here.

Rice, Houston Methodist award $90K for cancer research projects

seed grants

Rice University’s Synthesis X Center, in partnership with the Houston Methodist Neal Cancer Center, announced earlier this month the organizations would award $90,000 in seed grant funding to two projects that could help fight cancer. One would ease the pain of chemotherapy, while the other could change the way the progression of leukemia is tracked.

“We’re excited to be collaborating with the Neal Cancer Center to support collaborative, novel and interdisciplinary proposals to improve cancer care and outcomes,” Han Xiao, Rice professor of chemistry and the director of the SynthX Center, said in a news release. “Together, we can achieve translational excellence.”

The projects

Chemotherapy is one of the most effective cancer treatments, but it can be hard on the body. The human body doesn’t like being injected with radioactive material, especially the skin around the injection point, which can become extremely irritated. For patients in long-term treatment, the skin irritation can be more than just a bother; it can lead to infections that are dangerous to a compromised immune system.

Angel A Marti, a professor of chemistry at Rice University, and Biana Godin, an associate professor of nanoscience at Houston Methodist Research Institute, are experimenting with metal nanoclusters as a way to block radiation at the injection site. The nanocluster could be applied in a cream or a gel on the skin, serving as a type of shield against the harsh radioactive material.

Meanwhile, Yuan Ma, an assistant professor of chemistry at Rice, and Shu-Hsia Chen, a professor of immunology at Houston Methodist Research Institute, are working with m6A. Discovered in the 1970s, m6A is the most prevalent chemical modifier found in mRNA in mammals. It is prevalent in many cancers, including leukemia.

Ma and Chen are working on measuring the amount of m6A in leukemia to see if it can determine the most effective cancer treatments. The team is also experimenting with ways to shut off m6A to see if it makes current leukemia treatments more effective.

Progress from SynthX

SynthX was first launched in April 2024 to turn research from Rice and Houston Methodist into real-world cancer treatments. Within a year, the center had secured $1.5 million in grant money to work on crossing the blood-brain barrier in brain cancer treatments. These latest awards show that SynthX Center continues to bridge the worlds of research and clinical practice.

“This collaboration reflects a shared commitment to team science in cancer research,” Daniela Matei, the director of the Houston Methodist Neal Cancer Center, added in the release. “These are the types of translational and pioneering projects that lead to transformation in patient care.”'

The SynthX Center awarded $90,000 in seed grants to three teams in 2025 and $80,000 to three teams in 2024.
