I saved Tesla $50 million a year.

I'll do the same for you — at zero risk.

I don't take clients I'm not confident I can save $10M+

I audit your CAD and assembly line to strip out excess BOM cost. If I can't find savings, you pay nothing. If I do, I take 10% of the savings I free up for you in year one — capped at $1M. You keep 100% of the savings for the entire rest of the product's lifespan.

If your annual production costs are under $100M, I'm probably not the right fit. But if you're leaving millions on the table with over-engineered legacy components, let's talk.

For earlier-stage companies with compelling hardware problems, I selectively take on projects at flat rate or equity. Reach out — the worst I can say is not yet.
