The Altman brothers sure have a knack for being venture capitalists. On Tuesday, this especially applied to Jack Altman, co-founder of $3 billion-valuation HR software startup Lattice and brother to OpenAI CEO Sam Altman.

Jack Altman just announced a second $275 million fund for his solo-run firm Alt Capital. And from start to finish, it took him a week, he told The Wall Street Journal.

His first fund, raised in early 2024, was $150 million, so this is a big step up. He used it to invest in about 20 early-stage companies, he said, including David AI (a YC-alum that does data sets for speech models) and unicorn restaurant software maker Owner.com.
