  Sébastien Martin

  Co-founder & CEO

  "Security is not an add-on layer: it is the foundation of trust."

  A lawyer by training, Sébastien Martin spent five years studying French and German business law at Université Paris Nanterre and the University of Potsdam. A European childhood, in a family focused on security, international relations and the fight against fraud, taught him to connect the human, economic and institutional dimensions of risk. He speaks five languages: French, English, German, Spanish and Polish.

  He entered the crypto-asset ecosystem through its legal and compliance issues and quickly identified an under-anticipated risk: traceable wealth, identifiable executives, a digital threat that turns physical. He co-founded RAID Square in Paris in 2022 to turn that insight into action: more than 500 operations carried out in four years, while remaining self-funded, independent and sovereign, the condition for confidential casework.

  He frames digital investigation (OSINT, dark web, fund tracing and blockchain analysis) as evidence work: establishing facts and producing material that withstands challenge in litigation, arbitration and court proceedings. He also steers the cybersecurity strategy of regulated companies and the digital protection of executives and high-net-worth individuals, up to kidnapping or extortion situations linked to assets.

  Initiator of the Ligue pour la Sécurité du Web3 (LSW3) in 2024, integrated into ADAN in 2026, he now leads ADAN's Cybersecurity Commission, Europe's main blockchain and digital asset lobby, and is involved in the Franco-German think tank Eurosens.

  Esteban Lopes

  Co-founder & CTO

  "Boundless ambition, uncompromising security."

  A specialist in decentralised infrastructure and offensive security, Esteban Lopes trained in penetration testing from 2014 and in distributed systems from 2017 before focusing on blockchains. An independent security researcher until 2022, he took part in the early development on Solana before its launch, auditing projects and joining the first hackathon, then contributed to projects such as the infrastructure of an oracle that processed more than 70,000 transactions. He identified critical vulnerabilities in several exchanges and protocols, including Binance and projects in the Solana and Ethereum ecosystems.

  In a personal capacity, he is the author of Wabasen, an open-source file-encryption tool he created and develops independently of RAID Square. Files and folders are encrypted (XChaCha20-Poly1305) and protected by both a password and a crypto wallet, hardware wallets included. Cross-platform (Windows, macOS, Linux) and lightweight, written in Rust, its code is open and auditable by anyone, protecting data as much as funds.

  Co-founder and CTO of RAID Square since 2022, he leads technical and R&D operations: more than 500 digital operations (fund tracing, fraud, cyberattacks), including collaborations with government agencies, and dozens of cybersecurity audits (smart contracts, infrastructure), including audits conducted for licensing applications with the ACPR, the French banking regulator.
