Hi! I'm Mike Mettler (linkedin & x). I support & make small angel investments (usually $25k) in awesome people building things that help our planet. I prefer to get involved as early as possible, including being the first check. I like working directly with teams on product, sales, recruiting, and operations. I'm not as useful at the later growth stages. If you think I might be able to help, get in touch! Warm intros are nice but not required.
I've invested in AirMyne, Barnwell Bio, Bedrock Materials, Beeper (acquired by Automattic), Boom Supersonic, Cambrian Genomics (shut down), Channing Copper, Compound Eye, Critical Energy, Deep Fission, Elephant Energy, Elroy Air, Hexium, Kopperfield, Lightcell Energy, Lumen Energy, Lydian Labs, Seabound, Super, Tailscale, and Transition Biomining.
Some areas that I'm actively looking to fund/help (not restrictive - if you're working on something else, great):
Machine learning
- Catalysts for electrochemistry
- Minerals discovery
Chemical synthesis
- Low-temp plasma
- Cell-free biology
Mining
- In-situ recovery
Storage
- Chemical long-duration
Geothermal
- Heat transfer
Efficient computing
- Low power hardware for AI/ML
