N°043
I-Beam TheoristEric Ho
Co-founder & CEO, Goodfire AI · previously Co-founder & CEO, RippleMatch
Replaces opaque matching systems with geometrically legible intentional interfaces. Walked away from an $80M-backed recruiting company to write the for-profit alignment thesis, then built Goodfire — proving neural networks think in curved manifolds, not linear directions — to a $1.25B valuation and Anthropic’s first direct corporate venture bet.
