Dear Friends of Greentown,

Happy Earth Week! Our team is proud this week—and every week—to be supporting more than 200 groundbreaking climatetech startups as they develop, deploy, and commercialize their solutions. Check out just six of them in the Startup Spotlights section below, plus many of their recent wins under Startup News.

Earth Week is extra special here at Greentown, as we opened Greentown Houston on Earth Day 2021. To celebrate this milestone, we’re inviting you to an anniversary Transition On Tap!

The April 29 event will feature startup perspectives on developing and scaling climatetech in Houston. Join us to hear from longtime members Ian Bishop, founder and president of Elemental Advanced Materials, and Dr. Tara Karimi, co-founder and chief science & sustainability officer of Cemvita! We’re excited to have Greentown's CEO Georgina Campbell Flatter and Jane Stricker—a Greentown board member and the Houston Energy Transition Initiative’s senior VP, energy transition & executive director—provide remarks.

This Transition On Tap will also offer the opportunity to network with key leaders from throughout the region’s energy-transition ecosystem. We hope to see you there!

Warmly,
The Greentown Team

Startup Spotlights

Inductive Robotics delivers charging to cars that are sitting in parking lots, eliminating the need to demarcate specific parking spots with EV chargers. Its tech can be inexpensively deployed in a matter of days, without costly infrastructure installments.

Phoenix Tailings is pioneering the sustainable production of rare-earth metals that’s waste-free, net-zero, and cost-competitive with current methods.

Return to Vendor is developing an enhanced nylon—made from littered fishing nets—that can mimic the properties of other textiles, including stretch and wicking.

Revterra’s kinetic stabilizer offers many benefits for energy storage, from its long lifespan, to its full recyclability, to its high capacity. But the most game-changing feature? It plays nicely with the grid.

rStream is leveraging computer vision and data science to sort trash, recycling, and compost automatically. Watch its tech in action!

Investing Insights

Our Q1 investor roundtables were chock-full of insights into the rapidly changing climatetech-investment landscape. Check out key takeaways:

Everyone still believes in the urgent need to decarbonize, but the playbook is changing. Funding is harder to get, policies are shifting, and more than ever startups need to prove they can make money, not just make an impact.
The funding crunch is forcing discipline. Startups that have tightened operations, focused on customer revenue, and pursued capital-efficient models are thriving.
Some sectors may emerge as bipartisan winners. Grid resilience, domestic critical minerals, and nuclear energy were highlighted as areas where policy support could endure.
Industrial decarbonization, grid-edge innovation, and maritime and heavy transport may be pragmatic bets for a tough market.
