Investor Program Case Study


The Startup

Elemental Recycling, a Greentown Labs member, recycles all plastics and tires to create high-purity graphene, graphite, and hydrogen in a process that’s CO2 equivalent (CO2e) neutral.

The Investment

Elemental Recycling recently raised its Series A, led by Freestone, a portfolio company of Tailwater Capital. Freestone learned about Elemental Recycling through Greentown’s Deal Flow Digest—a core component of our Investor Program that showcases fundraising members to our investor network.

From the Startup

“It’s amazing how many people found us through the Deal Flow Digest.”

From the Investor

“The Deal Flow Digest is a great reference to stay up to date on who in the cleantech venture space is looking for capital and what the latest developments at each company are. It also allows for an easy filter by maturity and fundraising stage (pre-seed through Series B) and allows investors to reach out directly to founders to schedule introductory meetings. The inclusion of their pitch deck also gives more info than would be available on their website, so investors have a bit more info prior to meeting with companies.”
