What Functori does
Functori SAS is a privately held French deep-tech consulting and development firm founded in Paris in 2021, focused on blockchain infrastructure, formal methods and secure distributed systems. The five-person founding team combines 12+ years of R&D in programming languages and formal methods with 7+ years of applied blockchain experience, working in OCaml, Rust, Solidity, TypeScript and Rocq/Coq. Functori operates as a technical co-founder for fast-growing ventures in tokenization, gaming and infrastructure, and runs services spanning core protocol development, smart contract audits, formal verification, monitoring and a 'CTO-as-a-Service' offering for blockchain projects from pre-seed through fundraising.
The company has built a portfolio of proprietary and open-source tools that anchor its credibility. Apollo is a free, web-based opcode-level EVM transaction debugger; Argos is a commercial blockchain intelligence platform with multi-source address analysis, MEV detection, fund flow tracing and an MCP-server interface that exposes investigation workflows to AI agents; Atlas runs high-frequency arbitrage with sub-150ms latency across EVM networks; Pandora is a notarization and timestamping service on a sovereign rollup; Explorus visualizes consensus internals for Tezos; Factori generates static interfaces for Tezos smart contracts in TypeScript, OCaml, Python and C#; Mitten is a MITM proxy for testing Tenderbake consensus scenarios; and Crawlori and Gaia provide in-house indexing and API fuzzing. Joint ventures include Fraktion (RWA tokenization on Tezos), Goat Stadium (fan ownership in professional sports) and Mosaic Labs (gaming and infrastructure).
Functori generates revenue through professional services engagements, product monetization (Argos, Atlas, Pandora), and equity-aligned technical co-founder roles in joint ventures, supplemented by non-dilutive R&D funding of €10M+ from Horizon Europe, BPI France, the Tezos Foundation and academic partners including Inria, CEA, Université Paris-Saclay and Sorbonne Université. Go-to-market is enterprise field sales complemented by developer-led adoption via the free Apollo debugger, academic publications and open-source community presence. Customer logos span Tezos, Nomadic Labs, Ubisoft, Rarible, Trilitech, Sorbonne, Université Paris-Saclay and Tarides.
