Alt Capital

Alt Capital is the investment firm founded by Jack Altman, who previously built Lattice into a leading HR software platform. Altman : Sam Altman's brother : launched Alt Capital to invest in early-stage technology companies, bringing an operator's perspective to venture investing.

In February 2026, Benchmark hired Altman as its fifth general partner, with three Alt Capital team members joining him. The move effectively merges Alt Capital's portfolio and team into one of venture capital's most prestigious firms. Benchmark's equal-partnership model and its first GP addition in years made this one of the most watched VC personnel moves of 2026.

For founders, Alt Capital's track record matters because Altman invests like a builder, not a financier. His Lattice experience : scaling a SaaS company through product-market fit, enterprise sales, and multiple funding rounds : gives him pattern recognition that pure financial VCs lack.
