Episode notes
Greg's Path From Engineer To Donor Connector
- Greg moved from energy engineering to policy work then to 1.5°Climate after seeing gaps between technology, policy, and the money needed to scale solutions.
- He found nimbleness valuable: the org shifted from federal to state/local focuses after the 2024 election.
Solving Donor Paralysis With Free Vetting
- Founder Ning created 1.5°Climate to solve 'donor paralysis' — philanthropists who care but lack time/knowledge to vet climate opportunities.
- Ning funds operations so membership and donor services stay free, lowering barriers to entry.
Structure Vetting Around Themes And Landscape Work
- Use a steering committee and landscape assessments to focus vetting on themes and geographies, then interview hundreds of orgs to find the handful worth elevating.
- Host ~20 curated pitch events yearly so donors see only pre-vetted, high-impact opportunities.
