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.

Houston battery tech startup FlowCellutions acquired by Katy energy co.

M&A

Katy-based TerraFlow Energy, an energy storage and infrastructure company, has acquired Houston-based battery technology startup FlowCellutions. Financial terms weren’t disclosed.

FlowCellutions still operates under its established name, but with the tagline “A TerraFlow Energy Company.” Becca Segel, founder and CEO of FlowCellutions, now runs the business as its president.

FlowCellutions specializes in electrochemical sensing, diagnostics, analytics, and testing that offer insights into battery chemistry, charging capabilities, and system performance.

“FlowCellutions has always been focused on developing better ways to understand what is happening inside a flow battery and using that information to improve how these systems perform,” Segal said in a press release. “Joining TerraFlow gives us the opportunity to apply that work at a much larger scale while continuing to build the capabilities and expertise that make FlowCellutions unique.”

The FlowCellutions platform supports data centers and other heavy users of power. It’s designed to help reduce operating costs, prevent failures and costly downtime, and extend battery lifetime from about seven years to more than 30 years.

Segel founded the company in 2022. A member of Greentown Labs, the company raised more than $2 million in non-dilutive funding and received $1.5 million in National Science Foundation funding earlier this year.

FlowCellutions is one of five finalists in the Energy Transition Business category of InnovationMap’s 2026 Houston Innovation Awards.

“FlowCellutions brings a depth of scientific and technical expertise that fits naturally with where TerraFlow is going,” Jon Parrella, CEO of TerraFlow, said in the release.

“As we move from developing these systems to deploying them at commercial scale, understanding performance at a deeper level matters,” he said. “Bringing FlowCellutions into TerraFlow strengthens that capability and gives both teams more opportunity to advance the technology.”TerraFlow, founded in 2024, develops long-duration energy storage and power infrastructure for data centers, industrial facilities, utilities and other large power consumers.

meet the finalists

From IPOs to groundbreakings, some of Houston's most innovative companies reached major milestones this year.

As part of the 2026 Houston Innovation Awards, our Scaleup of the Year category honors innovative later-stage startups that have recently reached a significant milestone in company growth. Three scaleups have been named finalists for the 2026 award.

Read more about these businesses, their founders and their breakthrough technologies below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Erock

Energy infrastructure company Erock, previously known as Enchanted Rock, develops dual-purpose microgrids that rely on natural gas and renewable natural gas to produce lower carbon emissions and air pollutants than diesel generators. Its products can provide bridge power before grid interconnection, backup power during outages and dispatchable capacity that supports long-term grid reliability. The company has more than 1,100 megawatts of installed capacity and over 20 years of experience serving commercial, municipal and large-scale technology customers.

Erock completed its initial public offering this year, raising approximately $600 million in gross proceeds. It also grew its contracted power system sales backlog to approximately $1.7 billion, up tenfold year-over-year, with production sold out through 2028, according to the company's application. The company secured a major equipment order from Anthropic, began construction of the 366-megawatt El Paso Electric project supporting Meta's data center campus, and started assembly operations at its Hyperion facility in Cypress, Texas.

Hertha Metals

Hertha Metals produces lower-cost, lower-emission steel and high-purity iron. The company has developed a single-step process that uses natural gas as a direct reductant instead of metallurgical coal, which cuts production costs by more than 25 percent and emissions by up to 50 percent, according to the company. The same process produces high-purity iron needed for high-purity steels and rare earth magnets. The company says it aims to "re-industrialize America’s production of critical materials."

Hertha Metals was founded by CEO Laureen Meroueh in 2022 and emerged from stealth last year with more than $17 million in venture capital funding. The company closed a $133.65 million Series A this month and also broke ground on its $100M high-purity iron factory known as Chalyx in Conroe.

Venus Aerospace

Spacetech company Venus Aerospace is developing a high-thrust rotating detonation rocket engine (RDRE) that replaces the subsonic combustion used in conventional rocket engines. The RDRE is a compact, simpler engine that can deliver up to 15 percent greater efficiency for defense and space applications. It completed its first U.S. flight test of the engine last summer.

Venus Aerospace was founded in 2020 by CEO Cassie Duggleby and CTO Andrew Duggleby. It raised a $20 million Series A in 2022 and $42 million Series A2 in 2025. It closed a $91 million Series B earlier this year and expanded its leadership team. The company is working toward longer-duration and higher-thrust testing and advancing its flight program.

Texas ranks among top 10 best states for jobs in new report

jobs report

Business boosters often describe Texas as an economic engine. A new ranking from personal finance website WalletHub underscores that assessment.

WalletHub put Texas at No. 8 on its new list of the best states for jobs. Nebraska grabbed the No. 1 spot, and West Virginia landed at No. 50.

To compile the list, WalletHub evaluated 34 metrics from two categories: job market and economic environment. It then crunched the numbers to create a score for each state. A score of 100 represents the most favorable conditions for job seekers.

Texas ranked 25th in the job market category and second in the economic environment category. Texas’ eighth-place showing was based on a score of 59.23.

“The best states for jobs make it easier for residents to find and retain jobs, and employers in these states also offer very competitive compensation and benefits,” WalletHub analyst Chip Lupo said. “In addition, the top states are great places for people looking to raise a family, ranking among the best states for working parents.”

Data released in late October shows Texas led all states for job growth during the 12-month period that ended in September. In that time, Texas added 154,300 jobs at an annual rate of 1.1 percent.

“Texas is America’s jobs leader,” Gov. Greg Abbott said in a press release. “Businesses big and small invest with confidence in Texas and in our growing and skilled workforce. That means bigger paychecks for more Texans and more opportunities for Texas families to prosper for years to come.”

Abbott noted Texas reigns as the top state for attracting job-producing businesses and creating jobs at small businesses.

The Houston metro area actually saw a decline in new jobs in September, losing 7,300 jobs compared with the previous month. On a year-over-year basis, the region added 13,500 jobs, with professional and business services, construction, and private education and health services leading the growth.
