About me

Hi there 👋,

I’m Matt Delacour, CTO at CoinList. CoinList is a regulated platform for token sales, tokenized equities, and yield products, used by more than 12 million verified investors. We recently launched Passage, a platform where CoinList sits in the middle of asset providers (Superstate, Ondo, etc.) and distribution partners. Passage came with an SDK to make it as easy as possible to our partners to offer a vast regulated suite of products to their own users.
I lead an engineering organization of 30+ people building consumer fintech products across web, backend, and mobile. My work spans technical strategy, team-building, and the day-to-day judgment calls of shipping at velocity in a regulated industry.

I came up the unconventional way — I started by founding a B2C company, taught myself to code, and worked as a data scientist before moving into data engineering and backend. I started my long journey of becoming an engineering leader in 2023. That path still shapes how I think: product empathy, and well-crafted systems.

I care a lot about open source and the craft of building maintainable software. I’m the author and maintainer of tiny-orm, a small Rust ORM built for simplicity, and earlier I was a core maintainer of Feast, the open-source feature store.

These days I mostly write about engineering leadership, judgment and taste, and what AI-assisted development actually changes about the work, and what it doesn’t.

Quick timeline

Dec 2024 — Became CTO at CoinList, leading a 30+ person engineering organization through engineering managers and tech leads.
Apr 2024 — As Head of Engineering, led the team that shipped CoinList’s native iOS and Android apps, extending the platform to mobile.
March 2022 — Joined CoinList to build out their data team. I’d been curious about blockchain for a while, and it was a way into an industry I wanted to understand from the inside.
August 2022 — My team at Shopify released Merlin, the first in-house Machine Learning platform — about 1.5 years of work. My colleague Isaac wrote a great blog post on it.
2021 — Became a core maintainer of Feast, gave a talk on scaling its offline queries to billions of rows, and built an open-source Feast/Trino plugin that later moved into the official repo. Contributing to open source has been some of the most gratifying work I’ve done. © 2026 Matt Delacour
