Founder, CEO & CTO of Samouraï Coop, a worker cooperative from Paris that is a film crew and an engineering studio in one company, building and promoting open-source culture since 2016.
Co-founder of the Paris P2P Festival. For more than 12 years I've worked across the peer-to-peer, cybersecurity and open-source ecosystems, researching and building decentralized organizations. Alongside the coop, I lead samcrew, our gno.land team: core contributors to GnoVM and the gno.land chain, and one of its genesis validators. I also build Memba.

gnoland-1, live since mainnet launch on 12 September 2026. - Memba, on mainnet. 14 samcrew packages are live, from the App Store to escrow and an arcade leaderboard.
- Filming the chain. The crew keeps documenting gno.land: retreats, events, builders.
道 Four years in the gno.land core
Samouraï Coop has contributed to the gno.land core for more than four years. The crew has 256 merged pull requests in gnolang/gno, about one in eleven of every PR ever merged there, and more each year: 48 in 2024, 79 in 2025, 128 so far in 2026.
| what we do | |
|---|---|
| GnoVM | The interpreter, its type checker, stdlibs and test suite: most of our upstream work. |
| Security | Hardening the VM, consensus and p2p against crashes, overflows and malformed input. |
| Chain & tooling | gno.land node, tm2, genesis tools, gnodev, docs. |
| Validators | A genesis validator, gnomonitoring and the katana GovDAO daemon. |
| Governance research | Our research lab studies how cooperatives, DAOs and open-source projects govern themselves. gnodaokit and Memba are its output. |
| Design partner | We build our own products on gno.land and send what they teach us back upstream. |
| Documentation | Retreat and event reports for the core team, the Peer Dev tutorials, the WEB TRIP interviews. |
源 Open source
Everything we can open, we open. Our public gno repositories are on GitHub; the whole team page is at /u/samcrew.
作 Products
Products built and run by the coop, closest to gno.land first.
組 Inside Memba
Memba is an experimental operating system for decentralised organisations, and the direct output of our governance research. It is MIT-licensed and open source. Each of its parts is a product in its own right. Hover a card for details.
Every game uses one daily seed for everyone, drawn from a gno.land block, and needs no wallet.
録 gno.land on film
The crew films gno.land from the inside: brand films, core-team retreats, portraits of the teams building on it.
祭 Events
We produce the events we believe in, and we film the rest of the ecosystem's. Paris P2P Festival: five days of peer-to-peer at Ground Control, free, for 5,000 people. The Édition #1 talks are all online. Hyper Hacktive Festival: a film festival for independent documentaries funded by Samouraï Grants. It has had three editions, two at mk2 Quai de Seine, and sells its tickets on Zenao.
報 Contribution reports
Each year, one film shows everything the coop shipped.
学 Peer Dev: gno.land, taught on video
A 17-lesson curriculum, produced end to end by the coop, that takes a developer from an empty machine to GovDAO and the interrealm spec. Watch the playlist.
旅 WEB TRIP
Eight conversations with gno.land and web3 builders, filmed by the crew in 2024.
映 Films by the crew
40 festival selections, 3 wins. The Underground Sistine Chapel took Best Documentary at the London Independent Film Awards and was released free on both IPFS and YouTube.
