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.

Two other Houston companies were selected as finalists:

  • 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.

3 Houston innovators to know this week

who's who

Editor's note: Every week, I introduce you to a handful of Houston innovators to know recently making headlines with news of innovative technology, investment activity, and more. This week's batch includes three innovators across robotics, climatetech, and more.

After working for years in the downstream energy industry where safety and efficiency were top priorities, Dianna Liu thought there was a way technology could make a huge difference.

Despite loving her company and her job, she took a leap of faith to start a robotics company to create technology to more safely and efficiently monitor corrosion in pipelines. ARIX Technologies has developed software and hardware solutions for its customers with pipelines in downstream and beyond.

"Overall, this industry is an industry that really harps on doing things safely, doing things well, and having all the data to make really informed decisions," Liu says on the Houston Innovators Podcast. "Because these are huge companies with huge problems, it takes a lot of time to set up the right systems, adopt new things, and make changes." Continue reading.

Rawand Rasheed, co-founder and CEO of Helix Earth

Helix Earth Technologies closed an oversubscribed $5.6 million seed funding led by Houston-based research and investment firm Veriten. Anthropocene Ventures, Semilla Capital, and others including individual investors also participated in the round.

“This investment will empower the Helix Earth team to accelerate the development and deployment of our first groundbreaking hardware technology designed to disrupt a significant portion of the commercial air conditioning market, an industry that is ready for innovation,” Rawand Rasheed, Helix Earth co-founder and CEO, says in a news release.

In a guest column, Nada Ahmed, founding partner at Houston-based Energy Tech Nexus, draws a uniquely Houston comparison between the health tech innovation sector and that of the climate tech world.

"Over the past several decades, climate tech has faced numerous challenges, ranging from inconsistent public support to a lack of funding from cautious investors. While grassroots organizations and climate innovators have made notable efforts to address urgent environmental issues, we have yet to see large-scale, lasting impact," she writes.

"A common tendency is to compare climate tech to the rapid advancements made in digital and software technology, but perhaps a more appropriate parallel is the health tech sector, which encountered many of the same struggles in its early days," she continues. Continue reading.

Pharmaceutical giant looks to bring $5.9 billion facility to Houston

in the works

Pharmaceutical company Eli Lilly and Company is looking to build a $5.9 billion active pharmaceutical ingredient (API) manufacturing facility in Houston, according to a recent filing with the state of Texas.

The proposal states that the project plans to employ 604 full-time direct employees at the site upon ramp-up completion. These would include operations technicians, production specialists, maintenance support, quality control/assurance, engineering, administration, and management. Construction is projected to begin in 2026, with a completion target of 2030 and commercial operations beginning in 2031.

If completed, Lilly would purchase 236 acres at Houston’s Generation Park from McCord Development, the commercial development’s owner. The purchase would include multiple buildings, outdoor facilities, infrastructure buildout, and equipment installation.

This proposed Texas plant would be part of Lilly’s $27 billion effort to expand its U.S. production capacity, which was announced in February and includes construction on four new facilities in America. Lilly has previously referred to the plants as “mega sites.”

"This represents the largest pharmaceutical expansion investment in U.S. history," Lilly CEO David Ricks said during the February news conference.

The company has applied for school tax abatements under the new Texas Jobs, Energy, Technology, and Innovation program, according to reports from the Houston Business Journal. This incentive program allows school districts to limit the taxable value of a property for a portion of school taxes, which could save companies millions of dollars on a large portion of property tax bills. It also gives a 10-year tax cut for new manufacturing and development facilities, as long as there is localized job creation.

Houston airports poised for 1.3 million travelers on Memorial Day weekend

Taking Off

George Bush Intercontinental Airport (IAH) and William P. Hobby Airport (HOU) are estimated to see 1.3 million travelers during the Memorial Day period (May 20 - May 28). Despite large crowds, the airports say they have prepared with multiple new improvements designed to slow traffic and make check-ins easier.

“Air travel drives jobs, business and tourism — and this summer, Houston Airports is powering that growth,” said Jim Szczesniak, director of aviation for Houston Airports.

“From streamlined security to a smarter website to new flights and fresh amenities, we’re delivering improvements that support Mayor Whitmire’s call for a more user-friendly Houston. These upgrades aren’t just about moving people — they’re about moving our economy forward.”

IAH in particular has seen remarkable drops in wait times thanks to the new IAH International Arrivals Curb. Part of the $1.458 billion IAH Terminal Redevelopment Program (ITRP), it reduced airport traffic during the Christmas holidays by a whopping 99 percent, with the average wait time reaching only two minutes. Other improvements include TSA Precheck enrollment pods at both airports and the agility for international travelers to recheck bags without leaving the terminal after they have passed through customs.

The amount of travelers expected for Memorial Day is slightly below 2024 numbers, but Houston Airports expects record-breaking travel over the summer. Current estimates show 19.5 million people moving through both airports through Labor Day, a 250,000 increase over last year. Part of this can be attributed to IAH's increasing status as the gateway to Mexico, Central America, and South America, running nonstop flights to new tourist hot spots like Puerto Escondido.

In additions to streamlining the flight processes, Houston Airports are expanding concession and shop offerings. Hobby recently opened The Rustic, Chick-fil-A, Pei Wei, and Throughgood Bistro. Bush added Hip & Humble, a boutique gift and souvenir seller focused on the items for women travelers and those looking for a little luxury when they return home. And, as always, Houston Airports have some of the finest art in the country. All of it together makes traveling to and from the city much less stressful than the big crowds would portend.

"We’re ready to welcome millions with efficiency and a warm Houston spirit,” said Szczesniak. “This summer, travelers will see and feel the difference we’ve made.”

Houston e-commerce unicorn reaches $1.6B valuation with $50M fundraising round

fresh funding

Houston-based Cart.com, a provider of fulfillment and logistics services for B2C and B2B brands, has raised $50 million in venture capital, pushing its valuation to $1.6 billion. Since it was founded in 2020, Cart.com has raised $475 million.

Cart.com earned “unicorn” status in 2023 after securing a $60 million Series C round of funding. In the startup universe, “unicorn” refers to a private company that’s valued at $1 billion or more. Last year, Cart.com nailed down $130 million in debt funding, lifting its valuation to $1.2 billion.

Technically, Cart.com no longer qualifies as a startup. Rather, it’s now in “scaleup” territory. This term refers to a startup that has notched substantial growth and has maintained a stable workforce, among other positive achievements. Notable brands that have graduated from startup to scaleup include Airbnb, Peloton and Uber.

The $50 million round includes money from funds and accounts managed by BlackRock and Neuberger Berman, and new investors such as eGateway Capital, along with several unidentified venture capital firms, investors and family offices.

The company said it will use the fresh capital to fuel its global expansion through investments in infrastructure, technology, and M&A.

“Cart.com is continuing our strong growth trajectory across all operating metrics, and we intend to utilize this additional capital to accelerate the expansion of our platform and bring our customers new capabilities to enable their growth,” Omair Tariq, founder and CEO of Cart.com, said in a news release. Tariq added that his company is “well on our way to building the largest and most comprehensive platform in our space.”

Over the past 12 months, Cart.com completed its acquisition of OceanX, the fulfillment operation of direct marketing company Guthy-Renker, and Amify, an Amazon marketplace optimization and advertising platform. Bill Guthy, founder of Guthy-Renker, now sits on Cart.com’s board of directors
