Houston-based Aramco Americas, an arm of the Saudi Arabian energy giant, has joined climatetech incubator Greentown Labs as a top-tier partner.

“Aramco is committed to advancing technology solutions to lower carbon emissions. This partnership with Greentown Labs will deepen our ongoing engagement with climatetech innovators and startups,” Nabeel AlAfaleg, president and CEO of Aramco Americas, says in a news release.

In its role as a “Terawatt Partner,” Aramco Americas will gain access to activities within Greentown’s industry and entrepreneurial network. In addition, Aramco Americas will participate in Greentown’s Industry Leadership Council, an advisory group. Jim Sledzik, managing director of Aramco Ventures North America, will serve on the council.

Aramco’s partnership with Greentown Labs comes on the heels of last year’s announcement of the company’s $1.5 billion fund to invest in technology that supports the ongoing energy transition. Managed by Aramco Ventures, the VC arm of Aramco, the fund focuses on carbon capture and storage, greenhouse gas emissions, energy efficiency, nature-based climate solutions, digital sustainability, hydrogen, ammonia, and synthetic fuels.

To date, Aramco Ventures has invested in 22 startups and high-growth companies involved in the sustainability sector.

“Aramco Americas and Aramco Ventures have already exemplified what we look for in a partner: support of our entrepreneurs through investment and pilot opportunities, and engaging with our communities in Houston and Boston in the spirit of sustainability and climate action,” says Kevin Taylor, interim CEO and chief financial officer of Greentown Labs.

Greentown operates climatetech incubators in Houston and Somerville, Massachusetts.

2 Houston startups tapped for inaugural BIPOC-focused accelerator cohort

seeing green

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.
