4 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 a podcast with a tech founder supporting small businesses, a mom designing next-generation bibs, and two energy tech collaborators.

For decades, small businesses have operated in essentially the same manner — handwritten notes to request time off, manual punch cards to clock in, and verbal agreements to swap shifts. And 10 years ago, Houstonian Rushi Patel thought it was time to upgrade these local shops, eateries, and other businesses.

Homebase, which was founded in San Francisco in 2014 and has its largest office in Houston, provides a suite of software tools for employee scheduling, time tracking, communication, and task management for its users, most of which are small businesses.

After a decade of growing its technology and clientbase, Patel, co-founder and COO of the company, explains the unique challenges these small businesses face on the Houston Innovators Podcast — as well as how Homebase helps.

"It's a bit of an orchestra in terms of what entrepreneurs have to do. Your job is to compose a little, but conduct as well," Patel says on the show. "You've built the song of what you want to have happen, but you're conducting lots of different things to make it a reality as a small business owner." Read more.

Ashley Gooch has taken her entrepreneurial spirit from the fitness studio to the finger foods.

The Houston-based founder of high-end cycling studio RYDE and mom of three has launched a new baby gear brand, Babynetic. The company debuted its first product this month: the Babynetic bib.

Using a patented magnetic closure, the colorful platinum-grade silicone bibs are designed to snap and stay secured while holding up to four pounds of food. The snap is intended to be easy for parents to use, but more difficult for messy little hands to remove without assistance.

“As busy moms ourselves juggling careers and with five kids between us, we needed baby gear we could rely on,” Gooch said in a statement.Read more.

A group of Houston's innovation and energy leaders teamed up to establish an initiative supporting equitability in the energy transition.

Impact Hub Houston, a nonprofit incubator and ecosystem builder, partnered with Energy Tech Nexus to establish the Equitable Energy Transition Alliance and Lab to accelerate startup pilots for underserved communities. The initiative announced that it's won the 2024 U.S. Small Business Administration Growth Accelerator Fund Competition, or GAFC, Stage One award.

"We are incredibly honored to be recognized by the SBA alongside our esteemed partners at Energy Tech Nexus," Grace Rodriguez, co-founder and executive director of Impact Hub Houston, says in a news release. "This award validates our shared commitment to building a robust innovation ecosystem in Houston, especially for solutions that advance the Sustainable Development Goals at the critical intersections of industry, innovation, sustainability, and reducing inequality."

Houston tech founder shines spotlight on small businesses with new awards initiative

houston innovators podcast episode 234

For decades, small businesses have operated in essentially the same manner — handwritten notes to request time off, manual punch cards to clock in, and verbal agreements to swap shifts. And 10 years ago, Houstonian Rushi Patel thought it was time to upgrade these local shops, eateries, and other businesses.

Homebase, which was founded in San Francisco in 2014 and has its largest office in Houston, provides a suite of software tools for employee scheduling, time tracking, communication, and task management for its users, most of which are small businesses.

After a decade of growing its technology and clientbase, Patel, co-founder and COO of the company, explains the unique challenges these small businesses face on the Houston Innovators Podcast — as well as how Homebase helps.

"It's a bit of an orchestra in terms of what entrepreneurs have to do. Your job is to compose a little, but conduct as well," Patel says on the show. "You've built the song of what you want to have happen, but you're conducting lots of different things to make it a reality as a small business owner."



Patel explains how optimizing these personnel aspects of the business frees up founders and managers and improves the employee experience too. Currently, the job market is competitive for these types of businesses, and retention and hiring are major focus points for entrepreneurs.

With 10 years of data and experience of working with small businesses, Homebase introduced a new awards program this week in honor of National Small Business Week. The inaugural Top Local Workplace Awards honored over 50,000 businesses across the country for a range of positive workplace factors — like pay transparency and employee engagement.

"There are over 2 million employee-centric, main street type of businesses in the United States," Patel says, "these are the restaurants, the retailers, and the service providers. They employ north of 70 million people, so there's a lot of impact that these businesses can have. But what we found was they deserve recognition, and there wasn't recognition for the good practices that these employers were doing."

Using its data, which includes over 2.5 million hourly worker data points, Homebase's team implemented the awards to highlight the companies providing their employees — who are in most cases considered a work family, as Patel says — with a great experience.

Houston ranks No. 2 for share of AI talent in professional services

AI surge

Houston’s professional and business services sector—think law, accounting, consulting, and engineering firms—grabs one of the industry’s biggest shares of AI talent.

A report from commercial real estate services giant CBRE ranks Houston No. 2 among the top 50 U.S. and Canadian tech markets for the concentration of AI talent in professional and business services.

Houston’s share of AI talent in professional and business services stands at 26 percent, the report shows. Washington, D.C., tops the list at 31 percent. At 25 percent, Dallas-Fort Worth claims the No. 3 spot.

CBRE based the AI ranking on data from the LinkedIn networking platform.

The company’s researchers tallied 11,709 AI-related tech jobs in Houston. Nationwide, data scientists lead AI-related job growth in the U.S., according to the report.

“AI software and hardware developers are currently the most sought-after tech talent by employers,” the report says.

Houston faces AI talent gap

DoubleTrack, a provider of AI and data consulting, reported in June that Houston faces an AI talent gap.

“The places where businesses say they will adopt AI over the next six months, well ahead of where they are today, are mostly the same places already short on talent: Miami, Houston, and Denver among the metros, South Dakota and South Carolina among the states,” DoubleTrack said.

This labor shortage comes amid Houston’s ascent as an AI hub. For instance, a factory being built here by AI chipmaker NVIDIA and electronics manufacturer Foxconn will produce AI supercomputers and infrastructure systems.

Houston’s place in the sphere of tech talent

Overall, Houston ranks No. 32 in the CBRE report among the top 50 U.S. and Canadian markets for tech talent. The San Francisco Bay Area claims the top spot, with Austin at No. 5 and DFW at No. 8.

CBRE relied on 13 metrics to rank tech talent markets, including concentration of tech talent, tech talent pipeline, and research-and-development investments.

Here are other Houston details from the report:

  • In 2025, Houston’s tech talent workforce numbered 104,080, up 7.3 percent over the past three years.
  • Houston’s average wage for tech talent within the tech industry was $120,216 in 2025, up 13.3 percent over the past three years.

New pilot program for air taxis, Project Nexus, takes flight in Texas

Project Nexus

By 2029, Texas skies could be buzzing with air taxis, much like they are with drones today.

To kick off the "Project Nexus" pilot program in Texas, U.S. Transportation Secretary Sean Duffy, U.S. Sen. Ted Cruz, and Texas Department of Transportation officials attended an event September 10 at Fort Worth Alliance Airport, which serves as the launchpad for a statewide pilot program that could result in air taxis, self-piloted planes, and vertical take-off-and-landing aircraft permanently buzzing across the skies of Texas.

It was the first demonstration in Texas of next-generation aircraft under the pilot program; Texas is the sixth state to participate in the program.

Air taxi service on the radar
The federal government has teamed up with aviation companies BETA Technologies and Joby Aviation, as well as the Texas Department of Transportation, to develop regional air taxi service in Dallas, Austin, San Antonio, and eventually Houston.

Roger Venables, Fort Worth’s aviation director, said in January that he foresees regular air taxi service becoming a reality in the next five years.

On September 12, a Joby-made electric air taxi took a roundtrip flight between Fort Worth Alliance and Dallas Fort Worth International Airport to test flight operations.

The mission was part of a five-day test involving Fort Worth Alliance and DFW Airport flights, and flights over the Fort Worth Stockyards, Toyota Motor North America’s Plano headquarters, and other sites.

A new facility at Fort Worth Alliance will be Joby’s long-term home for regional flight operations.

Building a 'framework' for electric aircraft
TxDOT said Project Nexus is aimed at creating “a scalable system” to connect urban areas, rural communities, and neighboring states as air mobility technology advances.

In a TxDOT release, Marc Williams, the agency’s executive director, said the pilot program will “build a framework for how electric aircraft could one day connect people, goods, and communities across the state.”

Three-phase project will test flight capabilities

Initial flights in the third-year pilot program won’t carry passengers, according to TxDOT. Instead, the flights will gather data, validate air travel routes, and help improve the safety of air mobility technology.

The first phase of the U.S. Department of Transportation’s Project Nexus will feature piloted aircraft such as helicopters and fixed-wing planes. CultureMap previously reported Plano-based VertiPorts by Atlantic, which develops takeoff and landing sites for airplane-helicopter hybrids, would be part of Project Nexus.

The second phase will involve testing airborne medical and cargo logistics. This includes transporting critical medical supplies or donor organs between rural and urban hospitals in the Austin and San Antonio areas.

In the third and final phase, passengers will fly aboard air taxis across the Texas Triangle. Dallas-Fort Worth, Austin, Houston, and San Antonio anchor the triangle.

“In Texas, we don’t wait for the future to arrive, we build it,” Cruz said in the TxDOT release. “The Lone Star State is pushing the boundaries by testing the next generation of aircraft through Project Nexus.”

“These technologies will connect communities, expand access to jobs and services, and strengthen supply chains,” the senator added. “What starts in Texas will help shape the future of aviation throughout the entire country.”

Houston-area NASA contractor plans Nasdaq IPO

going public

Webster-based NASA contractor Rothe Development Inc. has filed paperwork with the U.S. Securities and Exchange Commission to go public.

Rothe, a minority- and woman-owned business, hasn’t yet identified how many shares it will sell and how much money its IPO might raise. Rothe plans to offer Class B common stock on the Nasdaq exchange.

CEO Karen Wheeler-Hall owns all of the Class A shares and would retain majority control after the IPO, according to the SEC filing. The company plans to use $2.4 million of the IPO proceeds so Wheeler-Hall can pay off a loan from the seller for her 2021 acquisition of Rothe.

From last December to this May, the company raised about $2.1 million in a pre-IPO private placement at $1 per share, the SEC filing shows.

Rothe runs NASA training lab in Houston

Founded in 1967, Rothe supplies engineering, technology, operations and technical services to NASA, the U.S. Department of Defense, other federal agencies, commercial space operators, and regulated industries.

Rothe is likely best known for operating NASA’s Neutral Buoyancy Laboratory in Houston. The lab trains astronauts for spacewalks and simulates space missions. It supports NASA’s International Space Station and Artemis programs.

Company sees room for growth

In the SEC filing, Rothe said it operates in several expanding markets driven by rising investments, including space exploration, national security, cybersecurity and digital infrastructure.

“We believe these market trends create significant opportunities for continued growth across both government and commercial sectors,” the company said.

Rothe generated nearly $126.4 million in revenue last year, up from $117.3 million the previous year. However, the company swung to a $700,000 operating loss in 2025 versus $1.8 million in operating income in 2024.

At the end of 2025, Rothe’s workforce comprised 385 employees and 25 subcontractors. The company also works in the cybersecurity, computer engineering, software development, multimedia and communication, and commercial calibration sectors, according to its website.
