Greentown Labs, which is co-located in the Boston and Houston areas, has announced its current CEO is stepping down after less than a year in the position.

The nonprofit's CEO and President Kevin Knobloch announced that he will be stepping down at the end of July 2024. Knobloch assumed his role last September, previously serving as chief of staff of the United States Department of Energy in President Barack Obama’s second term.

“It has been an honor to lead this incredible team and organization, and a true privilege to get to know many of our brilliant startup founders," Knobloch says in the news release. “Greentown is a proven leader in supporting early-stage climatetech companies and I can’t wait to see all that it will accomplish in the coming years.”

The news of Knobloch's departure comes just over a month after the organization announced that it was eliminating 30 percent of its staff, which affected 12 roles in Boston and six in Houston.

According the Greentown, its board of directors is expected to launch a national search for its next CEO.

“On behalf of the entire Board of Directors, I want to thank Kevin for his efforts to strengthen the foundation of Greentown Labs and for charting the next chapter for the organization through a strategic refresh process,” says Dawn James, Greentown Labs Board Chair, in the release. “His thoughtful leadership will leave a lasting impact on the team and community for years to come.”

Knobloch reportedly shifted Greentown's sponsorship relationships with oil companies, sparking "friction within the organization," according to the Houston Chronicle, which also reported that Knobloch said he intends to return to his clean energy consulting firm.

Greentown Labs names new CEO to oversee Houston, Boston incubators

seeing green

The largest climatetech incubator in North America has named an Obama Administration appointee as its next CEO.

Kevin Knobloch, who served as chief of staff of the United States Department of Energy in President Barack Obama’s second term, will be CEO of Greentown Labs, effective September 5. In his role, Knobloch will oversee both Greentown locations in Houston and Somerville, Massachusetts, outside of Boston.

“Kevin has a proven and impressive track record of growing, operationalizing, and leading a dynamic mix of organizations at different stages and in various industries, all of which have aligned with his unwavering commitment to addressing the climate crisis,” Greentown Labs Board Chair Dawn James says in a news release. “On behalf of the entire Board of Directors, I am thrilled to welcome Kevin as our next CEO. We are excited for what is to come under Kevin’s leadership and look forward to the positive impact he will undoubtedly have on our team, our startup community, and the ecosystem at large.”

With 30 years of experience across sectors, Knobloch most recently served as president of Knobloch Energy, an independent advisory and consulting firm. He also served as acting executive director of the National Offshore Wind Research & Development Consortium from June through December 2022. From 2018 to 2020, Knobloch was president of New York OceanGrid LLC, where he led Anbaric’s efforts to develop offshore wind transmission in New York.

“I’m honored and thrilled to have the opportunity to once again pass the leadership baton,” Greentown Co-Founder Jason Hanna says, who has been serving as interim CEO. “Especially so given Kevin’s incredible record of climate leadership. I’m excited for the future of this organization and the impact he can make as Greentown enters the second decade of its climate mission.”

The appointment follows an executive search that began after Greentown's previous CEO Emily Reichert announced she was stepping down in December.

“I’m delighted to be asked by Greentown Labs’ Board of Directors to be the next leader of this highly effective organization—and very excited to get to work,” Knobloch says in a statement. “I’ve long admired the critical role Greentown plays in supporting the growth and impact of early-stage climate and energy transition technology companies, as well as the impressive efforts by former longtime CEO Emily Reichert and the talented Board and staff to build Greentown into a national powerhouse and model for other incubators around the world. The climate crisis demands that we accelerate our collective pace of deployment and I look forward to collaborating with our startups, staff, and partners to support that acceleration.”

The announcement comes on the heels of Greentown naming its inaugural Houston general manager. Timmeko Moore Love was named to that new position last week.

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.
