Houston had a strong showing at the 2025 SXSW Pitch showcase in Austin, with two local startups claiming top prizes, including a novel clean-tech startup.

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.

"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, a Houston space data startup, also walked away a winner in the Security, GovTech & Space competition. 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.

"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,” Little Place Labs wrote on LinkedIn. "Today, that mission feels even stronger."

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

Two other Houston companies were finalists this year:

Trez, a Latino-focused fintech company that uses AI and voice-command payroll through WhatsApp to provide culturally relevant payroll and streamline financial operations for Latino business owners.
Tempesst Droneworx, a veteran-owned software company that's Harbinger software providing real-time contextual intelligence for early warning detection, reducing time to decision and speeding time to action.

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.

Under 30: Houston innovators snag spots on Forbes list of top young energy professionals

A handful of Houstonians have been named to the Forbes 30 Under 30 Energy and Green Tech list for 2025.

Kip Daujotas is an investment associate at Aramco Ventures, a $7.5 billion venture capital arm of the world's largest energy company. Houston is the Americas headquarters for Saudi Aramco. Since its inception in 2012, Aramco Ventures has invested in more than 100 tech startups. Daujotas joined the team over two years ago after studying for an MBA at Yale University. He led Aramco’s first direct air capture (DAC) investment — in Los Alamos, New Mexico-based Spiritus.

Also representing the corporate side of the industry, Wenting Gao immigrated from Beijing to obtain an economics degree from Harvard University, then got a job at consulting giant McKinsey, where she recently became the firm’s youngest partner. Gao works on bringing sustainability strategies to energy and materials companies as well as investors. Her areas of expertise include battery materials, waste, biofuels, and low-carbon products.

Last but not least, Houston entrepreneur Rawand Rasheed is co-founder and CEO of Houston-based Helix Earth. He co-founded the startup after earning a doctoral degree from Rice University and co-inventing Helix’s core technology while at NASA, first as a graduate research fellow and then as an engineer. The core technology, a space capsule air filtration system, has been applied to retrofitting HVAC systems for commercial buildings.

Each year, Forbes 30 Under 30 recognizes 600 honorees in 20 categories. The 2025 honorees were selected from more than 10,000 nominees by Forbes staff and a panel of independent judges based on factors such as funding, revenue, social impact, scale, inventiveness, and potential.

Specifically, the Energy & Green Tech category recognizes young entrepreneurs driving innovation that’s aimed at creating a cleaner, greener future.

“Gen Z is one of the fastest-growing groups of entrepreneurs and creators, who are reshaping the way the world conducts business, and our Under 30 class of 2025 proves that you can never begin your career journey too early,” says Alexandra York, editor of Forbes Under 30. “With the expansion across AI, technology, social media, and other industries, the honorees on this year’s list are pushing the boundaries and building their brands beyond traditional scopes.”

2 sustainability-focused student startups named to Houston accelerator

ready to grow

Rice University's Liu Idea Lab for Innovation & Entrepreneurship, or Lilie, has named eight teams to the second cohort of the Lilie Summer Venture Studio, and two have sustainability as a goal.

According to Rice, the 12-week program received a record number of applications, that spanned the campus' degree offerings.

“We are thrilled to see such a high level of interest and excitement from Rice students for a high-growth venture accelerator,” Kyle Judah, executive director of Lilie, said in a statement. “The diversity and creativity in this year's applications were truly inspiring, and we’re excited to support these promising ventures with the resources and mentorship they need to hit escape velocity and create the next generation of pillar companies for Houston, Texas and the world.”

The selected teams will receive $15,000 in non-dilutive funding from the accelerator, along with access to coworking space and personalized mentorship in the Liu Idea Lab.

Coflux Purification, a patent-pending in-stream module that breaks down PFAS using a novel absorbent for chemical-free water, was named to the cohort, as was Solidec, a technology platform that extracts molecules from water and air, transforms them into pure chemicals and fuels without any carbon emissions.

Here are the rest of the teams for the 2024 Lilie Summer Venture Studio:

Docflow, focused on streamlining residency shift scheduling
JewelVision, building virtual fitting rooms for jewelry e-commerce retailers using generative AI
Levytation, using data science and AI to answer critical questions about sales and customers for coffee shop management
OnGuard, a marketplace to book off-duty police officers and security professionals
Roster, leverages data on athletes in the NCAA Transfer Portal to automatically send updates on players to coaches
Veloci, a running shoe venture that addresses common pains through shoe design

Lilie launched the Summer Venture Studio last year. According to Rice, two out of the six teams selected, Helix Earth Technologies and Tierra Climate, which both also tackle sustainability challenges, raised venture capital funds after completing the accelerator program.

Helix Earth Technologies also went on to earn the inaugural TEX-E Prize at CERAWeek in 2023.

“The track record of our Summer Venture Studio Accelerator speaks for itself, despite being early in our second year," Taylor Anne Adams, head of venture acceleration programs at the Liu Idea Lab, said in a statement. "This is the power of entrepreneurship programming that is designed by founders, for founders, that happens at the Liu Idea Lab.”

Last year, Lilie also named 11 successful business leaders with ties to Houston to its first Lilie’s Leadership Council. Each agreed to donate time and money to the university’s entrepreneurship programs.

Tesla announces annual meeting under pressure from shareholders

Tesla Talk

Tesla has scheduled an annual shareholder meeting for November, one day after it came under pressure from major shareholders to do so.

Billionaire Elon Musk's company said in a regulatory filing on Thursday that the meeting would be held Nov. 6, but that may prove troublesome because it comes nearly three months after it is required to do so under state law in Texas, where the company is incorporated.

The annual meeting, given Tesla's fortunes this year, has the potential to be a raucous event and it is unclear how investors will react to the delay, which is rare for any major U.S. corporation.

Tesla shares have plunged 27% this year, largely due to blowback over Musk's affiliation with President Donald Trump, as well as rising competition.

The announcement of the meeting comes a day after a group of more than 20 Tesla shareholders sent a letter to the company's board pressing for an annual meeting after receiving no word of one with the deadline just days away.

Many shareholders have been miffed by Musk's participation in the Trump administration this year, saying he needs to focus on his EV company which is facing extraordinary pressures.

“An annual meeting provides shareholders with the opportunity to hear directly from the board about these concerns, and to vote for or against directors, the board’s approach to executive compensation, and other matters of material importance,” the group said in the letter.

The group cited Texas law, which requires companies to schedule annual shareholders meetings within 13 months of the prior annual meeting.

Tesla’s last shareholders meeting was on June 13 of last year, where investors voted to restore Musk’s record $44.9 billion pay package that was thrown out by a Delaware judge earlier that year.

Also on Thursday, Musk that the Grok chatbot will be heading to Tesla vehicles.

“Grok is coming to Tesla vehicles very soon. Next week at the latest,” Musk said on social media platform X, in response to a post stating that Grok implementation on Teslas wasn't announced on a Grok livestream Wednesday.

Grok was developed by Musk’s artificial intelligence company xAI and pitched as an alternative to “woke AI” interactions from rival chatbots like Google’s Gemini, or OpenAI’s ChatGPT.

Shares of Tesla rose 3% at the opening bell after tumbling this week when the feud between Trump and Musk heated up again.

Greentown Labs names Lawson Gow as its new Houston leader

head of hou

Greentown Labs has named Lawson Gow as its Head of Houston.

Gow is the founder of The Cannon, a coworking space with seven locations in the Houston area, with additional partner spaces. He also recently served as managing partner at Houston-based investment and advisory firm Helium Capital. Gow is the son of David Gow, founder of Energy Capital's parent company, Gow Media.

According to Greentown, Gow will "enhance the founder experience, cultivate strategic partnerships, and accelerate climatetech solutions" in his new role.

“I couldn’t be more excited to join Greentown at this critical moment for the energy transition,” Gow said in a news release. “Greentown has a fantastic track record of supporting entrepreneurs in Houston, Boston, and beyond, and I am eager to keep advancing our mission in the energy transition capital of the world.”

Gow has also held analyst, strategy and advising roles since graduating from Rice University.

“We are thrilled to welcome Lawson to our leadership team,” Georgina Campbell Flatter, CEO of Greentown Labs, added in the release. “Lawson has spent his career building community and championing entrepreneurs, and we look forward to him deepening Greentown’s support of climate and energy startups as our Head of Houston.”

Gow is the latest addition to a series of new hires at Greentown Labs following a leadership shakeup.

Flatter was named as the organization's new CEO in February, replacing Kevin Dutt, Greentown’s interim CEO, who replaced Kevin Knobloch after he announced that he would step down in July 2024 after less than a year in the role.

Greentown also named Naheed Malik its new CFO in January.

Timmeko Moore Love was named the first Houston general manager and senior vice president of Greentown Labs. According to LinkedIn, she left the role in January.
