Ideas
Sandy Kory Founder, Horizon 3:49
Talent-dense, mission-driven, contrarian culture wins.
Sandy invested in Palantir's 2009 bridge round after his friend and Palantir CTO Sham Sankaran raved about the talent density and mission. He valued the team's extreme first-principles thinking, ambition, dedication, and radically contrarian culture even though the company could not clearly explain its business model or GAAP revenue at the time. He put a large portion of his net worth in because he believed this could be the smartest, most ambitious group in Silicon Valley.

Founders explain hard science, overachieve.
Sandy found BillionToOne through the short-lived YC Fellowship and backed it pre-seed, then doubled down and made it his largest angel investment, including at a $4 million valuation. He was impressed by three brilliant PhD founders who were raw, honest, not bullshitters, and able to explain highly technical biology to a non-expert. They were intellectually honest about risks, overachieved repeatedly, and built a profitable diagnostics business with NIPT and liquid biopsy, reaching roughly a $400 million revenue run rate with 100% growth.

Democratizes custom manufacturing with inbound demand.
Sandy first invested in SendCutSend in its 2021 seed round and later doubled down through an SPV. He knew founder Jim through M&A and trusted him. SendCutSend democratizes custom manufacturing by letting anyone order one part online, using top-tier machines rather than trying to sell machines, which contrasts with failed 3D-printing startups that lacked demand. It has strong inbound demand from tinkerers and industrial customers tied to re-industrialization, defense tech, and robotics, is like AWS for hardware startups, and benefits from China's slower or less compliant competition for fast or restricted parts.
