“Reducing Houston’s emissions and leading a global transition is a community-wide effort and will require action from residents and the business community. This is why it’s more important than ever to have partners and organizations like Greentown Labs, whose mission is to solve the climate crisis through entrepreneurship and collaboration.

“When we decided to move operations to the U.S., we didn’t have anything here. We were selected for more than one incubator, but we decided to go with Greentown Houston. All the help Greentown Labs has given us, from the beginning, has been amazing. All the networking that we’ve done through Greentown was very, very helpful, and was one of the reasons we decided to move everything to the U.S.”
