Greentown Labs has accumulated several new corporate partners in the past year.

The nonprofit climatetech incubator with locations in Houston and Somerville, Massachusetts, has a roster of over 80 corporates that provide funding, pilot opportunities, mentorship, and more.

In March, Ecopetrol joined Greentown as a Terawatt Partner, the highest level partner for the incubator. The company, which the Colombian government holds a majority ownership stake in, has integrated business across the hydrocarbon value chain, as well as low emission solutions and energy transmission. The company followed TotalEnergies, which joined at the Terawatt level, in January, and GE Vernova, a global energy company, which was announced as a partner in November.

Greentown's other new Terrawatt Partners include sustainable building solutions company Holcim and Boston Consulting Group, which helped the organization enhance its strategy for the future.

"As part of the partnership, BCG guided Greentown through a mission, vision, and strategy refresh aimed at maximizing the nonprofit incubator’s impact over the next several years," reads the Greentown Labs news release.

These are the other new additions to Greentown's corporate roster at the other levels:

• Cell Signaling Technology (Gigawatt Partner), a life science company founded, owned, and led by active research scientists
• SLB (Gigawatt Partner), a global technology company focused on innovating oil and gas, delivering digital at scale, decarbonizing industries, and developing and scaling new energy systems that accelerate the energy transition
• Embraer-X (Megawatt Partner), the disruptive innovation company of Embraer, the world’s third-largest aircraft manufacturer
• Koppers (Megawatt Partner), an integrated global provider of treated-wood products, wood-treatment chemicals, and carbon compounds
