Building hyper ambitious startups that deliver energy abundance.

Kunal’s story ↓

Groq

Language on silicon. Not a GPU farm.

LPU. Less energy per token. Deterministic inference. Stop confusing FLOPs with a blackout.

Nth Cycle

Electricity in. Critical metals out.

Oyster. Electro-extraction. No foreign furnace. First U.S. nickel-cobalt MHP from scrap. Commercial.

Amprius

More energy per kilo. Not more kilos.

SiCore. Silicon in the anode, not graphite. Up to 450 Wh/kg. Drones and stratospheric aircraft stay up longer.

Kunal’s story 01 / 04

The red lights

There’s a special kind of silence before the red lights go out on a race track.

Your brain inventories every variable at once.

Lights out

That precise moment clarifies something simple, life only pays out to decisive drivers who race to the first corner.

The history

In 1973 the lines wrapped the block and energy security stopped being a phrase.

Lithium ion showed up in 1991 and then it crawled. That’s the history.

The present

The present is harder.

If the teams who tell the truth on the ugly days keep shipping what works and fixing what fails, that’s the best memorial.

Minutes given back to humanity, that’s the future we want to live in where energy abundance arrives.

Escape velocity

Startups aren’t about forecasting.

It’s about finding the people who refuse to be average and then adding more friction so they can move at escape velocity.

What we do

Investing in hyper ambitious startups that deliver energy abundance. We go after boring problems most do not want to touch and solve them with ridiculous tech taking a monopolistic approach.
