Ido Fishman: Ironman and triathlon.
Ido Fishman is an AI investor: Founder and Managing Partner of Milenny Ventures, an early-stage firm in Limassol, Cyprus backing the founders and infrastructure behind applied AI. Before the first call of the day he is a long-distance triathlete: six mornings a week in the water, on the bike, on the road, since 2018.
The endurance work is not a hobby that sits next to the investing. It is where the temperament gets built. A full Ironman rewards the same things an early-stage position rewards: a long plan held through boring middles, honest numbers, and no improvisation on race day. This page is the record, with each result linked to its public timing data.

Why it matters to the work
The connection to the day job is mechanical, not poetic. A twelve-month training block and an early-stage thesis run on the same clock: long horizons, small compounding inputs, and no credit for looking good at the ninety-day mark. He has written about both halves of that idea, in The quarter is the wrong unit of progress and Training plans and investment theses have the same shape. The current block points at a second sub-ten attempt at the full distance.
