An accelerator focused on supporting BIPOC-led climatetech startups and addressing inequities in the climatetech industry is accepting applications for its second cohort.

Greentown Labs, the largest climatetech incubator in North America, and Browning the Green Space (BGS), a nonprofit dedicated to making clean energy and other climate-related fields more diverse, equitable, and inclusive, lead the Advancing Climatetech and Clean Energy Leaders Program (ACCEL), which offers access to funding, networking connections, resources, and opportunities that structural inequities put out of reach.

“Opening applications for Year 2 of ACCEL is an important milestone in strengthening critical support for traditionally excluded entrepreneurs in our communities,” says Kerry Bowie, executive director and president of Browning the Green Space.

Benefits for startups accepted into the ACCEL program include:

  • gaining access to extensive mentorship from industry experts
  • $25k in non-dilutive grant funding
  • a curated curriculum of workshops led by experts — including from VentureWell — covering various essential topics for early-stage climatetech founders, such as customer discovery, design-thinking, startup finance, storytelling, and more

“Through our partnership with Greentown and VentureWell, we are able to put our respective strengths together to create an ambitious program to bolster founders of color in climatetech and propel innovations that benefit communities most impacted by climate change,” Bowie says.

For Year 2 of ACCEL, Greentown and BGS are seeking applications from startups at Technology Readiness Levels (TRL) 1-4 that are developing climate solutions for the electricity, transportation, buildings, manufacturing, agriculture, and resiliency and adaptation sectors. Applications are due January 5, 2024.

The Year 2 request for applications comes as a successful inaugural year of ACCEL winds to a close.

ACCEL Year 1 featured six startups working on innovations as diverse as sneakers made from food waste, ultracapacitors built with hemp sourced from Black and Indigenous farmers, and ultra-light solar panels.

Their accomplishments during the accelerator included raising equity funding, earning acceptances into additional accelerators, winning grants, executing customer discovery, and more. Check out more results from Year 1 of ACCEL here.

“ACCEL is one of the most impactful, meaningful programs we’ve run to date,” says Greentown Labs CEO and president Kevin Knobloch. “We are eager to expand upon the great success and momentum of Year 1, and to welcome another incredible cohort of BIPOC-led startups that are developing much-needed climatetech solutions. We’re equally committed to helping these companies accelerate and deploy their solutions, while also helping to build a more diverse, inclusive climatetech workforce — ACCEL sits at the nexus of those two critical efforts.”

Zach Ellis Jr., founder and general partner of South Loop Ventures, says the firm wants to address the "billion-dollar blind spot" of inequitable distribution of venture capital to underrepresented founders of color. The Houston-based firm recently closed its debut fund for more than $21 million. Learn more.

Ty Audronis and his company, Tempest Droneworx, made a splash at SXSW Interactive 2025, winning the Best Speed Pitch award at the annual festival. The company is known for it flagship product, Harbinger, a software solution that agnostically gathers data at virtually any scale and presents that data in easy-to-understand visualizations using a video game engine. Audronis says his company won based on its merits and the impact it’s making and will make on the world, beginning with agriculture. Learn more.

Houston-based Persona AI and CEO Nicolaus Radford continue to make steps toward deploying a rugged humanoid robot, and with that comes the expansion of its operations at Houston's Ion. Radford and company will establish a state-of-the-art development center in the prominent corner suite on the first floor of the building, with the expansion slated to begin in June. “We chose the Ion because it’s more than just a building — it’s a thriving innovation ecosystem,” Radford says.

Houston university to launch artificial intelligence major, one of first in nation

BS in AI

Rice University announced this month that it plans to introduce a Bachelor of Science in AI in the fall 2025 semester.

The new degree program will be part of the university's department of computer science in the George R. Brown School of Engineering and Computing and is one of only a few like it in the country. It aims to focus on "responsible and interdisciplinary approaches to AI," according to a news release from the university.

“We are in a moment of rapid transformation driven by AI, and Rice is committed to preparing students not just to participate in that future but to shape it responsibly,” Amy Dittmar, the Howard R. Hughes Provost and executive vice president for academic affairs, said in the release. “This new major builds on our strengths in computing and education and is a vital part of our broader vision to lead in ethical AI and deliver real-world solutions across health, sustainability and resilient communities.”

John Greiner, an assistant teaching professor of computer science in Rice's online Master of Computer Science program, will serve as the new program's director. Vicente Ordóñez-Román, an associate professor of computer science, was also instrumental in developing and approving the new major.

Until now, Rice students could study AI through elective courses and an advanced degree. The new bachelor's degree program opens up deeper learning opportunities to undergrads by blending traditional engineering and math requirements with other courses on ethics and philosophy as they relate to AI.

“With the major, we’re really setting out a curriculum that makes sense as a whole,” Greiner said in the release. “We are not simply taking a collection of courses that have been created already and putting a new wrapper around them. We’re actually creating a brand new curriculum. Most of the required courses are brand new courses designed for this major.”

Students in the program will also benefit from resources through Rice’s growing AI ecosystem, like the Ken Kennedy Institute, which focuses on AI solutions and ethical AI. The university also opened its new AI-focused "innovation factory," Rice Nexus, earlier this year.

“We have been building expertise in artificial intelligence,” Ordóñez-Román added in the release. “There are people working here on natural language processing, information retrieval systems for machine learning, more theoretical machine learning, quantum machine learning. We have a lot of expertise in these areas, and I think we’re trying to leverage that strength we’re building.”
