The Opportunity

Problem

Freelance climatetech developers struggle to find consistent clients for carbon tracking apps because enterprises prefer established agencies over solo freelancers.

Solution

CarbonMatch is a niche marketplace where freelance developers showcase carbon tracking portfolios and get matched with enterprises seeking specialized apps. It verifies dev expertise via GitHub integrations and provides client leads vetted for budget and urgency. Solo devs win more projects by appearing in a trusted, climate-focused network that bypasses general freelance sites.
