green businesses in the Grina network
Your green business.
Ready to grow.
Enterprise Support & Investment is Grina Foundation’s work to help green businesses in Tanzania grow, become investment-ready and connect to finance. We do it through three programmes and one network. Every business starts by joining the network.

One network.
The way in to everything we offer.
Every route to Grina’s support starts here. Register your business once, and you’re visible when funders, corporates and development partners come looking for businesses like yours. Opportunities, training and introductions reach you through the network, so you don’t have to chase them alone.
We want as many green businesses in Tanzania as possible to join. The more businesses in the network, the more opportunities we can bring to it.
You register yourself. We don’t showcase you, we match you.
Clean Energy · Circularity & Green Cities · Smart Mobility · Blue Economy & Nature-Based Solutions · Smart Agriculture & Food System · Carbon Markets

The right meeting beats a hundred introductions.
Grina Deal Rooms bring green businesses together with financiers, buyers and partners, pre-matched so every conversation is relevant. We hold them several times a year, in different parts of Tanzania.
At the 2026 Summit, 16 hosts, including investors, financiers and development partners, held more than 300 meetings with businesses over two days.
Why be in the network?
When a funder or corporate brings us a need, we go to the network first. If you’re registered with a complete profile, you’re who we think of.
Stay connected as you grow.

- Financial readiness support
- Quarterly meetups and networking events
- Exclusive member Deal Rooms
