Neostack is a personal investment vehicle for early-stage bets in AI and developer tools. Conviction-led, founder-first, long horizon.
Neostack invests at the earliest stage in companies building the tools, models and infrastructure that define the next decade of software.
We focus on AI and developer tools — areas where small teams of exceptional builders can compound into category-defining companies. Investments are personal, conviction-driven, and made with a long time horizon.
Based in Stockholm. Run by Emil Ahlbäck.
