A new accelerator focused on BIPOC-led energy tech startups named its inaugural cohort, and two Houston-based companies made the cut.

The new program — Advancing Climatetech and Clean Energy Leaders Program, or ACCEL — is an initiative led by Greentown Labs and Browning the Green Space that was originally announced in November. The program was established to provide access to funding, networking connections, resources, and more to BIPOC-led startups working on a climatetech solution.

The program is supported by the Massachusetts Clean Energy Center, or MassCEC, a state economic development agency, and the Boston-based Barr Foundation, a Boston-based foundation. Each of the selected startups will receive a $25,000 grant, incubation at Greentown, mentorship from Greentown and BGS’s networks, and access to a curriculum curated by VentureWell, a nonprofit with deep expertise in the climatetech space.

“We are thrilled and eager to support this exceptional cohort of startup leaders as they tackle some of our world’s biggest climate challenges,” says Kevin T. Taylor, CFO and interim CEO at Greentown Labs, in a news release. “Through partnerships with Browning the Green Space and VentureWell—and with the support from MassCEC and the Barr Foundation—we look forward to offering intentional mentorship, training, and networking opportunities to help these BIPOC-led startups thrive.”

The co-located program will host startups at each of the two Greentown Labs locations in the Houston and Boston areas. The inaugural cohort includes:

  • Active Surfaces, based in Salem, Massachusetts, unlocks dual land-use applications through its ultra-thin-film, flexible solar technology. Its co-founders are Shivam Bhakta and Richard Swartwout.
  • Houston-based DrinKicks is a sneaker-themed consumer-products company that is focused on repurposing food waste and recycled materials into sustainable goods such as shoes, sports equipment, and clothing, all while educating consumers on the power of the circular economy. The company was co-founded by Kristeen Reynolds, Michael Fletcher, and Kristen Lee.
  • EarthBond, headquartered in Cambridge, Massachusetts, leverages group financing and carbon accounting to lower costs and risk in the energy transition of Nigeria's $14B fuel-based, off-grid generator market. Chidalu Onyenso founded the business.
  • Amherst, Massachusetts-based florrent is a bio-based materials and energy storage company providing solutions to address critical bottlenecks to the global decarbonization and electrification of utilities, transportation, and buildings. Its co-founders are Jose LaSalle, Joe Hastry, and Alexander Nichols. florrent is a current Greentown member.
  • frakktal, founded in Houston by Jhana Porter, is a B2B materials company developing bio-based polymer processes for the replacement of fossil-fuel-based feedstocks across industries. The company is a current Greentown member.
  • SpadXTech from Worcester, Massachusetts, is contributing to the reduction of CO2 emissions impacting several industries such as packaging, textiles, transportation, filtration, and construction through the manufacturing of its core and versatile material platform technology. Its co-founders are Lina M. González and Connor Crawford.

“We are inspired by and excited to support the wealth of innovation and fresh perspectives on climate solutions offered by our inaugural ACCEL cohort of startup leaders,” said Kerry Bowie, executive director and president of Browning the Green Space. “Through this partnership with Greentown Labs we are able to build critical support infrastructure for entrepreneurs of color and accelerate the equitable development and distribution of climate solutions across all communities.”

The program will officially kick off at an event on February 23 at Greentown’s Boston location.

Climatetech incubator announces C-suite promotion, Houston jobs, and nonprofit transition

greentown updates

The new year has brought some big news from Greentown Labs.

The Somerville, Massachusetts-based climatetech incubator with its second location at Greentown Houston named a new member to its C-suite, is seeking new Houston team members, and is in the process of transitioning into a nonprofit.

Juliana Garaizar, who originally joined Greentown as launch director ahead of the Houston opening in 2021, has been promoted from vice president of innovation to chief development and investment officer.

"I'm refocusing on the Greentown Labs level in a development role, which means fundraising for both locations and potentially new ones," Garaizar tells InnovationMap. "My role is not only development, but also investment. That's something I'm very glad to be pursuing with my investment hat. Access to capital is key for all our members, and I'm going to be in charge of refining and upgrading our investment program."

While she will also maintain her role as head of the Houston incubator, Greentown Houston is also hiring a general manager position to oversee day-to-day and internal operations of the hub. Garaizar says this role will take some of the internal-facing responsibilities off of her plate.

"Now that we are more than 80 members, we need more internal coordination," she explains. "Considering that the goal for Greentown is to grow to more locations, there's going to be more coordination and, I'd say, more autonomy for the Houston campus."

The promotion follows a recent announcement that Emily Reichert, who served as CEO for the company for a decade, has stepped back to become CEO emeritus. Greentown is searching for its next leader and CFO Kevin Taylor is currently serving as interim CEO. Garaizar says the transition is representative of Greentown's future as it expands to a larger organization.

"Emily's transition was planned — but, of course, in stealth mode," Garaizar says, adding that Reichert is assisting in the transition process. "She thinks scaling is a different animal from putting (Greentown) together, which she did really beautifully."

Garaizar says her new role comes alongside Greentown's return to nonprofit status. She tells InnovationMap that the organization originally was founded as a nonprofit, but converted to a for-profit in order to receive a loan at its first location. Now, with the mission focus Greentown has and the opportunities for grants and funding, it's time to convert back to a nonprofit, Garaizar says.

"When we started fundraising for Houston, everyone was asking why we weren't a nonprofit. That opened the discussion again," she says. "The past year we have been going through that process. ...I think it's going to open the door to a lot more collaboration and potential grants."

Greentown is continuing to grow its team ahead of planned expansion. The organization hasn't yet announced another location — Garaizar says the primary focus is filling the CEO position first. In Houston, the hub is also looking for an events manager to ensure the incubator is providing key programming for its members, as well as the Houston innovation community as a whole.

Houston scientists create platform for long-lasting, precise drug delivery

drug breakthrough

A team of Rice University scientists has developed a new drug delivery platform that researchers say can slow the rate of drug release, which has major implications for drug efficacy and potentially cancer immunotherapy.

The research was published in Nature Nanotechnology, and supported by the National Science Foundation, the National Institutes of Health, the Cancer Prevention and Research Institute of Texas and the Welch Foundation.

In the study, the team demonstrated how a peptide hydrogel functions as a three-dimensional network that controls the rate of release across a range of medication types, including small-molecule drugs and biologics such as insulin and antibodies. The system, called self-assembling boronate ester release (SABER), uses reversible chemical bonds between the peptide and the drug molecule to extend the duration of drug release. Instead of passing quickly through the net, the drug gets temporarily “stuck” each time it binds to the peptide, which slows its passage out of the hydrogel, according to Rice.

The researchers formulated a tuberculosis-treating drug into a hydrogel. They used it to treat infected mice with a single injection of the drug-laden hydrogel. In the test, the hydrogel outperformed almost daily oral administration of the medication over two weeks. Insulin packaged in SABER hydrogels successfully controlled blood sugar levels in diabetic mice for six days in another set of experiments.

Brett Pogostin, a Rice doctoral alum who led the development of SABER and served as first author of the study, began working on self-assembling peptides as an undergraduate student at Rice. Jeffrey Hartgerink, a professor of chemistry and bioengineering at Rice, and Kevin McHugh, associate professor of bioengineering and chemistry and a Cancer Prevention and Research Institute of Texas scholar, advised Pogostin and served as corresponding authors on the study.

Pogostin’s work aimed to bridge foundational materials research and biomedical applications. SABER was inspired by a drug delivery course taught by McHugh, where Pogostin learned about dynamic covalent bonds used in glucose sensing, where the bonds reversibly form and break apart. That quality inspired Pogostin to adapt the concept for drug delivery.

“Brett really drove this project in a way that is, in my experience, unusual for a graduate student,” Hartgerink said in the news release. “It’s a very versatile approach. You can make both small-molecule drugs and very large biologics sticky with the type of chemistry that Brett developed.”

The team demonstrated the platform in two different use cases with Tuberculosis and Type 1 diabetes, with SABER simplifying dosing and enhancing the efficacy of the drugs. Hartgerink described the current SABER system as “generation one,” and plans to work to make it widely applicable. He is looking into how SABER could be applied to cancer immunotherapy.

“What I’m really passionate about right now is cancer prevention — trying to think about how we can use materials to prime the immune system to prevent cancer from ever happening as opposed to just treating it,” Pogostin added.
