Ido Fishman. AI investor. AI builder. Ironman finisher.
Ido Fishman is the Founder and Managing Partner of Milenny Ventures, an early-stage firm backing the founders, teams, and infrastructure behind applied AI. He writes checks from pre-seed through Series A and sits close to the operator work that defines modern AI companies.
Unusually for an investor, he ships. He runs his own production stack of AI agents across daily operations, the kind of hands-on build-and-break that most check-writers stopped doing years ago. That context shows up in how he diligences founders and how he advises them after the wire hits: not from a deck, from the terminal.
What he invests in
Pre-seed and seed AI companies with a clear compounding advantage. Preference for infrastructure, developer tools, vertical agents, and founders who ship weekly. Ticket size scales with conviction, not committee.
What he builds
An in-house stack of AI agents running daily operations: email triage, project intelligence, financial reconciliation, training analysis, reputation monitoring. The same patterns he looks for in founders are the ones he ships in his own workflow.

The discipline of a twelve-month training block and the discipline of a twelve-month investment thesis, he has found, are closer than most people realize.
Where he works from
Limassol, Cyprus. A useful vantage on both European and Middle-Eastern AI ecosystems. He writes in English about what is actually working at the builder-investor seam.
