I invest where energy infrastructure actually gets built.
Deep-tech climate investor. At Azolla Ventures I back hardware and hard science — the physical systems that get energy infrastructure sited, built, and run at gigaton scale. Principal at Azolla Ventures — previously at NextEra Energy Investments, and deep tech at Lockheed Martin.

Principal, Azolla Ventures
I back deep tech — hardware and hard science that abate carbon at gigaton scale. At Azolla, that means leaning into the physical layer: software alone rarely clears ≥0.5 Gt of annual abatement, hardware gets there more directly.
I've underwritten energy from three sides: hardware-side deep tech at Lockheed Martin, software and AI investing at NextEra Energy Investments — where the mandate was the digital layer, not the physical one — and now deep-tech climate venture at Azolla Ventures, back on the hardware side by choice.

| # | focus | thesis |
|---|---|---|
| 01 | deep tech | hardware and hard science reach gigaton scale directly that clears 0.5 Gt |
| 02 | the gigaton filter | impact is the size of the prize — ≥0.5 Gt CO₂e/yr, or it doesn't clear the bar |
| 03 | grid resilience | interconnection, hardening, robotics for high-risk field work — unglamorous, and usually skipped |
| 04 | pre-consensus sourcing | markets misprice founders and problems that don't pattern-match — that mispricing is the edge |

A monthly, pre-consensus look at deep tech and hard science in energy infrastructure — what clears the gigaton bar, and what doesn't, before it's consensus.
Get in touch.
Building deep tech for energy, the grid, or high-risk field infrastructure? I want to hear about it.
