Dimitris Koutentakis is Co-Founder and CEO of Atomarine, a Y Combinator-backed startup building floating, nuclear-powered data centers at sea to solve the AI infrastructure power crisis.

A quadruple MIT graduate, Dimitris holds a BS and MEng in EECS, an MS in Mechanical Engineering, and an MBA from MIT Sloan, with deep roots in the Greek shipping industry.

Dimitris brings a rare combination of quantitative finance, engineering optimization, and maritime heritage, positioning him uniquely at the intersection of compute infrastructure and offshore energy.

Before Atomarine, he was a Portfolio Management Associate at Arrowstreet Capital ($200B AUM) and at Amazon designed fleet charging optimization that quantified $193M in CapEx avoidance.

Atomarine's modular offshore platforms target 75 to 100 MW per barge, scaling to a 450 MW campus, with a first pilot deployment planned for 2028 and a long-term transition to compact marine nuclear reactors.
