About Max Digiacomo-Castillo
Max Digiacomo-Castillo is based in San Francisco. Aristotle's September 2026 funding announcement lists him as an engineer at Latent Health. RocketReach, a contact-data aggregator, lists him as a Member of Technical Staff at Latent since 2024. It also lists him as co-founder of Aineko from 2022 to 2024. These details come from a third-party database and could not be confirmed on a personal site.
He studied Computer Science at Stanford University and appears in the university's 2025 commencement program under the name Maximino DiGiacomo-Castillo. Earlier public records show research work on blockchain and cryptocurrency, including a 2020 paper on model checking Bitcoin and other proof-of-work consensus protocols. MIT's Trancik Lab also lists him as a student researcher.
His one public AI investment found so far is Aristotle. Aristotle is a voice-first AI tutoring platform for students ages 13 to 18. It announced a $5M seed round on September 16, 2026. True Ventures led the round, with Wicklow Capital and a group of angels from AI and tech companies. The announcement names Max among the angels, with the title Engineering, Latent Health. The Lounge deals desk also records this round as Aristotle Seed, $5M, September 2026.
There is not enough public information to describe a stated thesis. The only confirmed round is a seed-stage AI company in education technology. He has not published a check size, target stage or sector list that we could find. Founders pitching him should expect an engineer's view of product and technical depth, but that is an inference from his background and not something he has said.
