Crypto Consultant

Colas Gabriac is a Consultant at Sia Partners, where he has focused on crypto and blockchain since December 2018. His areas of coverage include public blockchains, decentralised finance (DeFi), automated market makers (AMMs), MEV, high-frequency trading, stablecoins, and tokenisation. In November 2024, he was interviewed by The Big Whale on the subject of blockchain-based AI agents, discussing the mechanics of LLM-based autonomous agents, the Truth Terminal case study, and the emergence of AI-managed investment vehicles such as AI16z. He explained how AI agents trained on open-source large language models can develop distinct behaviours and interact autonomously on-chain, including executing financial strategies on DeFi protocols such as Aave or Morpho.

Prior to joining Sia Partners, Gabriac worked as a Blockchain Developer at Lombard Odier Group from February to August 2018, based between Grenoble and Geneva, and as a Blockchain Analyst at Allianz France from March to August 2017 in Paris.
