What Set In Stone does

Set In Stone (legal entity BENOIT IMPULSION SARL) is a French cybersecurity company specializing in smart contract vulnerability analysis for the Web3 and blockchain ecosystem. Its core product is an automated scanning engine that ingests Solidity source code — via deployed contract address, GitHub repository, or ZIP archive — across 25+ blockchain networks including Ethereum, Arbitrum, Base, Polygon, BNB Smart Chain, Optimism, Linea, Mantle, Fantom, Gnosis, Celo, and Cronos, and produces a security score, a vulnerability report, and (in its Security Assistant product launched April 2024) AI-assisted remediation guidance, all driven by an in-house proprietary vulnerability reference framework.

The business operates a hybrid product-led and sales-led model. Acquisition is driven by a free homepage scanner (email-gated) that delivers an instant security assessment without payment, after which users can convert to a paid Individual subscription (1 report/month + 100 API calls) or Professional subscription (10 reports/month + 1,000 API calls). Higher-margin revenue comes from a custom-quoted Code Security Assistance service combining full analysis with hands-on code remediation, plus re-audit engagements. A REST API enables platforms to embed scanning functionality and security scores inside third-party products, positioning the company for both SMB self-serve volume and selective enterprise integration.

The company is founder-led (Thomas BENOIT serves as manager and Data Protection Officer), privately held as a French SARL, and currently structured at 1–10 employees with offices at Campus Cyber in Puteaux and a registered address in Senlis. It carries no disclosed institutional investors or funding rounds, and has built credibility through analyst recognition (Wavestone Radar 2024 and 2025) and selection for the StartinBlock Top 100 at Paris Blockchain Week 2024.
