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, Astro Mechanica, Barnwell Bio, Bedrock Materials, Beeper (acquired by Automattic), Boom Supersonic, Cambrian Genomics (shut down), Channing Copper, Compound Eye, Critical Energy, 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):

Hydrocarbon synthesis

- Solar to fuel

Storage

- Thermal and chemical long-duration

Geothermal

- Superhot rock / enhanced geothermal

Efficient computing

- Low power hardware for AI/ML
