MassVentures

florrent makes ultracapacitors with hemp grown by Black and Indigenous farmers. It met its largest investor, MassVentures, through Greentown's Deal Flow Digest.

Greentown's been incredibly supportive. The Investor Program has led to so many investor conversations, some of which are already lined up for when we're ready to raise our seed. MassVentures is a great example: they're our biggest investor, and that connection was through Greentown Labs.

Florrent

florrent has a strong team; they listen well; and their technology is making the right advances. florrent hits our investment sweet spot and we are grateful to Greentown Labs for bringing the startup to our attention.

Freestone / Tailwater Capital

Elemental Recycling turns plastics and tires into high-purity graphene, graphite, and hydrogen. Freestone, a portfolio company of Tailwater Capital, led their Series A after discovering them through the Deal Flow Digest.

It's amazing how many people found us through the Deal Flow Digest.

Elemental Recycling

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.
