Greentown Labs announced that it added five startups to its Houston community in Q1 of 2025.

The companies are among a group of 19 that joined the climatetech incubator, which is co-located in Houston and Boston, in the same time period. The companies that joined the Houston-based lab specialize in a number of "green" applications, from converting plastic waste into sustainable materials to developing energy-storage solutions.

The new Houston members include:

  • Concept Loop, a project of Pakistan-based Innova8e Inc., aims to repurpose post-industrial and post-consumer plastic waste into sustainable building materials.
  • GeoFuels, a Sugar Land-based company that produces hydrogen by using baseload geothermal power and methane pyrolysis.
  • PLASENE, a Houston-based company with an innovative platform that converts plastic waste into liquid fuel and low-carbon hydrogen through its proprietary catalysts and modular, scalable, pre-engineered units platform. The company was named to Greentown's ACCEL Year 3 cohort earlier this year.
  • RepAir Carbon, an Israeli company with a fully electric, zero-heat carbon-removal technology that consumes minimal energy, operates without liquids or solvents, and produces no hazardous materials or waste.
  • RotorVault from Pasadena, California, is commercializing energy-storage and load-following solutions that are containerized, modular, and field-deployable systems built on flywheel technology.

Fourteen other companies will join Greentown Boston's incubator. See the full list here.

PLASENE and five other new members—Thola, Respire Energy, Andros Innovations, FAST Metals and Tato Labs—join Greentown Labs through its most recent Advancing Climatetech and Clean Energy Leaders Program, or ACCEL, cohort. ACCEL, which works to advance BIPOC-led startups in the climatetech space, announced its third cohort last month.

Houston private equity firm beats target on first investment fund

fresh funds

Houston-based private equity firm Sallyport has raised $160 million for its first investment fund, exceeding the target amount by $10 million.

The Sallyport Partners Fund focuses primarily on investments in founder- and family-owned businesses, corporate carve-outs and startups in various industries.

The firm’s chairman, Doug Foshee, seeded the fund. He and managing partners Kyle Bethancourt and Ryan Howard started the firm in 2023.

“Sallyport Partners Fund was created to utilize the proven processes our team has developed over time to generate value for like-minded investors on a larger and more impactful scale,” Foshee says in a news release.

Investors in the Sallyport fund include entrepreneurs, business executives and influential Texas families. Aside from Foshee, names of the fund’s investors weren’t disclosed.

“We are deeply committed to working hand-in-hand with management teams to drive transformative growth and generate long-term value,” says Bethancourt. “Our operational capabilities are forged from decades of firsthand experience leading, investing in, and building thriving businesses from the ground up. We have a unique appreciation for the management team’s perspective because we’ve been in their shoes.”

Those shoes have covered some pretty impressive ground:

  • Foshee is former chairman, president, and CEO of Houston-based El Paso Corp., which owned and operated a 44,000-mile natural gas pipeline network. In 2012, El Paso merged with Houston-based pipeline company Kinder Morgan in a multibillion-dollar deal.
  • Before Sallyport, Bethancourt was a vice president in the credit division of Blackstone, an investment powerhouse with more than $1 trillion in assets under management. Earlier, he worked at D.E. Shaw & Co., a New York City-based hedge fund with more than $65 billion in assets under management.
  • Before Sallyport, Howard worked at Platform Partners, a Houston-based private equity firm. Earlier, he worked for the natural resources arm of investment banking giant Goldman Sachs.

Launching and growing small businesses and startups can take a village, and Houston Community College has a program that can help be that village for entrepreneurs.

HCC's HOU Made, which launched in 2021 and is run from HCC's West Houston Institute, is a free initiative that provides programming — workshops, resources and networking — to local businesses.

"It is designed to open up HCC's Makerspace to the public with access to tools and resources that were previously reserved for staff, faculty and students,” Connie Leon, the program’s coordinator, says in a news release. “The initiative gives small business owners access to use the Makerspace after their representatives attend a series of workshops.”

In addition to the workshops, which range from business 101 and branding to scaling operations, participants have access to equipment like laser cutters, 3D printers and heat press machines. One program within HOU Made is the Maker to Market initiative that provides entrepreneurs with materials including tents, tables, and marketing collateral to help set up pop-up stores for markets.

The program also provides opportunities with key financial advisers and partners like Chase Bank. LaShan Arceneaux, owner of Three Lumps of Sugar that creates mixes for cocktails, secured a $12,000 startup loan from participating in the program.

"I plan to use the loan to have a website built, and to purchase equipment and business supplies such as mixers, aprons, and supplies needed for business. This will allow me to grow the business successfully," Arceneaux says in the news release.

10th Houston cohort named to early-stage accelerator

ready to grow

National venture capital firm gener8tor named its 10th Houston cohort this week, which includes startups focused on innovative tableware to substitute teacher operations.

gBETA Houston offers startups and founders with a non-equity seven-week program that features intensive concierge coaching and access to a network of investors and partners. The founders will pitch their ideas on Oct. 24 at 6:30 p.m. at the Esperson Building.

"Each cohort shows us how innovation evolves and thrives," Muriel Foster, gBETA Houston director, says in a statement. "The Spring 2024 gBETA Houston cohort embodies creative brilliance and unyielding ambition."

The five companies named to gBETA were chosen based on their growth potential and investor readiness. They include:

  • BrainBuffet, an AI-powered platform that has already created over 250 courses to refine its personalized learning algorithm that builds customized courses that feature curated content, YouTube videos, quizzes, and progress tracking
  • Colorfull Plates, a tableware startup that creates durable, vibrant products that aim to streamline family meals and encourage children to try new flavors. It has generated $300,000 in revenue without outside dilutive funding.
  • The Parent Teacher Collaborative, a web- and mobile-based platform that aims to improve student outcomes by building strong collaborative partnerships, growing parent-teacher organizations and better managing school events. It's worked with five Houston-area communities and has raised over $144,000 in grant and contract funding since April 2023.
  • Kinfolk, a user-friendly mobile application that creates a digital time capsule of family traditions, memories and cultural heritage. It has over 50 beta-testing customers.
  • SubSpark, a mobile and desktop app that allows school administrators and teachers to post available openings for substitute teachers. The Houston-based LLC is currently beta-testing its apps with one Houston-area private school.

The five companies joined the spring 2024 cohort and the rest of the Houston gBETA network.

gBETA is supported by Downtown Houston, the City of Houston and the Downtown Redevelopment Authority. The program has accelerated 45 Houston companies since its launch in Houston in 2019. It was launched by a $1.25 million grant to be paid out over five years.

Expert: Demystifying SBIR grants for Houston startups

guest column

Grants are everywhere, all the time, but often seem unobtainable for startups. Most companies tell me about their competitors winning grants but don’t know how to secure non-dilutive funding for themselves. It’s true that the SBIR program is competitive — with only 10 to 15 percent of applicants receiving awards — but with a little guidance and perseverance, they are most definitely obtainable.

An SBIR overview

The Small Business Innovation Research program was introduced on the federal level in 1982 with the purpose of de-risking early technologies. While most investors are hesitant to invest in a company that’s still in ideation, the SBIR program would provide an initial level of feasibility funding to develop a prototype. The program issues funds to companies without taking any equity, IP, or asking for the money back.

Since its inception, the SBIR program has funded over 200,000 projects through 11 different federal agencies, including, but not limited to, the Department of Defense, the National Institute of Health, and the National Science Foundation. Federal agencies with R&D budgets over $100 million dedicate at least 3.2 percent of their budget to the SBIR program to fund research initiated by small businesses.

Eligibility and application process

It is no surprise that only small businesses can apply for this non-dilutive funding. For SBIR purposes, a small business is defined as being a for-profit entity, smaller than 500 employees, 51 percent owned by US citizens or permanent residents, and not primarily owned by venture capital groups. This small business must also have the rights to the IP that needs de-risking.

To apply, the small business must have a specific project that needs funding. Normally, this project will have three specific aims that detail the action items that will be attempted during the funded period. Some agencies require a pre-application, like a letter of intent (DOE) or a project pitch (NSF). Others don’t have a screening process and you can simply submit a full application at the deadline. Most agencies published examples of funded or denied applications for you to review.

SBIR phases

Phase I of the SBIR program is the normal entry point for every agency. It takes your product from ideation, through a feasibility study, to having a prototype. While agencies provide various funding amounts, the range is between $75,000 to $300,000 for 3 to 12 months of R&D activities. Applications contain a feasibility research plan (around six pages), an abstract, specific aims, supporting documents, and a budget.

While some programs allow for Direct to Phase II (D2P2) applications, most don’t apply for Phase II until they have secured Phase I funding. This second phase allows companies with completed feasibility studies to test their new prototype at a larger scale. The budgets for this phase range from $600,000 to $3 million and span an average of two years. The research plan is twice as robust and a commercialization plan is also needed.

Tips for success

If you’re wondering if your technology would be a good fit for a certain program, you can start by looking at the SBIR website to see the previously funded projects. The more recent projects will give you an idea of the funding priorities for each agency. Most abstracts will allude to the specific aims, meaning you can get a sense of the research projects that were approved. If you regularly see an agency funding projects similar to yours, you can search sbir.gov/topics for that agency’s research topics and upcoming deadlines.

Your team is one of the most important aspects of the application. Since you will be reviewed by academic experts, it’s helpful to have a principal investigator on your project that has a history of experience or publications with similar technology. Keep in mind that this principal investigator must be primarily employed by your company at the time of the grant. If this individual is employed by a university or nonprofit research organization, consider taking the STTR route so you can utilize their expertise.

Preparing Phase I applications should take no less than eight weeks, and Phase II should take at least ten. Your first step should be read the entire solicitation and create action items. The early action items should be

  1. Completing government registrations, like SAM.gov
  2. Writing your abstract and specific aims
  3. Contacting the program manager or director for early feedback

Any bids, estimates, or letters of support may also take time to receive, so don’t delay pursuing these items.

Don’t stop trying

If you speak to any program officer, they will encourage you to keep applying. For resubmissions, you will have a chance to explain why your previous application was denied and what you’ve done to improve. Most companies receive funding on the resubmission. If you get the feeling that a specific agency isn’t the right fit, reach out to other agencies that may be interested in the technology. You may realize that a small pivot may open up better opportunities.

There are frequently published webinars from different agencies that will give overviews of the specific solicitations and allow for Q&A. If you feel stuck or are still concerned about getting started, reach out to an individual or group that can provide guidance. There are plenty of grant writers, some of which have reviewed for the SBIR program for different agencies, who can provide strategy, guidance, reviews, and writing services to provide different levels of help.

Securing SBIR funding can be a game-changer for startups. While the process may seem daunting at first, with the right approach and persistence, it’s very obtainable. Remember, each application is a learning experience, and every iteration brings you closer to success. Whether you seek support from webinars, program officers, or professional grant writers, the key is to keep pushing forward. The potential rewards far outweigh the challenges, and with determination, your startup could be the next SBIR success story.

Four startups from across the country won over $160,000 in cash prizes from the U.S. Department of Energy’s Office of Technology Transitions earlier this month, and a Houston-area company claimed the top prize.

Hertha Metals, based in Conroe, won first place at the 2024 Summer Energy Program for Innovation Clusters (EPIC) Startup Pitch Competition. The program honors and supports clean energy innovators nominated by clean technology business incubators.

“The EPIC Pitch Competition is a unique opportunity for start ups to highlight their technology, get on the main stage, and receive direct funding,” DOE Chief Commercialization Officer and Director of OTT Vanessa Chan says in a news release. “The startup pitch winners have honed their entrepreneurial skills and demonstrated a critical understanding of their technological impacts, targeted markets, and scalable strategies.”

Focused on environmentally responsible steel, Hertha Metals won the $100,000 prize. The company's steelmaking process reduces emissions by 95 percent, per the news release, while remaining financially accessible. Hertha Metals was nominated by Greentown Labs, which won $25,000 for its nomination.

The program's other 2024 winners included:

Hertha Metals was founded by Laureen Meroueh, a mechanical engineer and materials scientist, in 2022. A Greentown Houston member, the company is also currently in the inaugural cohort of the Breakthrough Energy Innovator Fellows.

Houston VC funding surged in Q1 2025 to highest level in years, report says

by the numbers

First-quarter funding for Houston-area startups just hit its highest level since 2022, according to the latest PitchBook-NVCA Venture Monitor. But fundraising in subsequent quarters might not be as robust thanks to ongoing economic turmoil, the report warns.

In the first quarter of 2025, Houston-area startups raised $544.2 million in venture capital from investors, PitchBook-NVCA data shows. That compares with $263.5 million in Q1 2024 and $344.5 million in Q1 2023. For the first quarter of 2022, local startups nabbed $745.5 million in venture capital.

The Houston-area total for first-quarter VC funding this year fell well short of the sum for the Austin area (more than $3.3 billion) and Dallas-Fort Worth ($696.8 million), according to PitchBook-NVCA data.

While first-quarter 2025 funding for Houston-area startups got a boost, the number of VC deals declined versus the first quarters of 2024, 2023 and 2022. The PitchBook-NVCA Monitor reported 37 local VC deals in this year’s first quarter, compared with 45 during the same period in 2024, 53 in 2023, and 57 in 2022.

The PitchBook-NVCA report indicates fundraising figures for the Houston area, the Austin area, Dallas-Fort Worth and other markets might shrink in upcoming quarters.

“Should the latest iteration of tariffs stand, we expect significant pressure on fundraising and dealmaking in the near term as investors sit on the sidelines and wait for signs of market stabilization,” the report says.

Due to new trade tariffs and policy shifts, the chances of an upcoming rebound in the VC market have likely faded, says Nizar Tarhuni, executive vice president of research and market intelligence at PitchBook.

“These impacts amplify economic uncertainty and could further disrupt the private markets by complicating investment decisions, supply chains, exit windows, and portfolio strategies,” Tarhuni says. “While this may eventually lead to new domestic investment and create opportunities, the overall environment is facing volatility, hesitation, and structural change.”

Expert: Texas is building a cybersecurity wall — but it needs more bricklayers

Guest Column

Texas has always been a state that thinks in terms of scale. Big energy, big ambitions and now, big action in cybersecurity.

With the creation of the Texas Cyber Command under the Department of Information Resources, the state is recognizing what many of us in the industry have long understood: cybersecurity is not just an IT issue, it's a matter of public safety and economic resilience. Protecting municipal systems, schools, and critical energy infrastructure from cyber threats is no longer optional. It is essential.

For these efforts to succeed, Texas must invest as much in people as it does in technology. Without a capable, well-trained workforce to carry out the mission, even the strongest cyber strategies will struggle to hold the line.

The scope of the threat

Cyberattacks are not theoretical. In the last year alone, several cities in Texas experienced major ransomware attacks. One incident in Fort Worth took down core city systems, affecting everything from email access to permitting operations. The ripple effects were significant.

The energy sector is also under constant pressure. As a cornerstone of both the Texas and national economy, the it is a high-value target. Hackers are probing systems that manage oil, gas, and renewable energy infrastructure, looking for weaknesses that could be exploited to steal data or disrupt operations.

Texas has responded by centralizing its cyber incident response capabilities. The Texas Cyber Command is a smart step forward. It brings coordination and focus to an increasingly complex landscape. But its effectiveness will depend entirely on the professionals tasked with doing the work. And that’s where the challenge lies.

The workforce gap

Across the U.S., there are an estimated 400,000 unfilled cybersecurity positions. In Texas, more than 40,000 roles remain vacant, according to CyberSeek. These are not just numbers in a report. They represent a growing vulnerability with gaps in frontline defenses against real and persistent threats.

We cannot afford to rely solely on traditional pathways to fill this gap. Four-year degree programs are important, but they are not designed to scale fast enough or flexibly enough to meet today’s needs. Instead, we need to broaden our view of what a cybersecurity talent pipeline looks like and who it includes.

There needs to be an expanded focus on practical, skills-based training that takes high-aptitude individuals, including those from non-traditional backgrounds, and prepares them for success in cybersecurity careers through rigorous hands-on training that reflects the demands of real-world cyber roles. With the right structure and support, people from all walks of life are already proving they can become capable defenders of our digital infrastructure.

The same entrepreneurial spirit that drives innovation in other sectors can be applied to cybersecurity workforce development. We don’t have to wait years to grow the next generation of defenders. We can do it now, with the right focus and investment.

Texas has taken a critical first step by creating the Cyber Command, but if we want to build lasting resilience, we need to address the workforce bottleneck head-on. Cybersecurity needs more than tech…it needs talent.
