Hi! I'm Mike Mettler. 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, science, and sales. 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, American Supercritical, Amplify Computing, Astral Materials, Barnwell Bio, Beeper (acquired by Automattic), Boom Supersonic, Borealis Fusion, Cambrian Genomics (shut down), Channing Copper, Compound Eye, Critical Energy, Deep Fission (SPAC'ed into Surfside), Elephant Energy, Elroy Air, Hexium, Kopperfield, Lightcell Energy, Ludwig Computing, Lumen Energy, Lydian Labs, Recast Systems, Seabound, Standard Thermal, Super, SuperCool Earth, Tailscale, and Transition Metal.

Some areas that I'm actively looking to fund/help (not restrictive - if you're working on something else, great):

- Nuclear interactions (fusion, fission, isotopes, etc.)

- Geothermal

- Energy conversion

- Geoengineering
