Alt Capital is a 2023-founded San Francisco firm that has built an unusually large early-stage portfolio (40+ companies) in just two years, functioning as a tiny team that writes $1-25M checks like a much larger institutional fund but maintains direct founder relationships. The firm differentiates itself through founder Jack Altman's operator background (previously built Lattice) and "founder-philosopher-led" approach, quickly becoming a preferred co-investor for top-tier firms like Sequoia and Y Combinator in competitive AI and software rounds.
