This week, Chainalysis welcomes Sebastien Giroux as the company’s Chief Financial Officer. As a key member of the leadership team, Seb will lead the finance organization and serve as a bridge builder across functions as we invest in Chainalysis’s next phase of growth: helping enterprises move on-chain.
Seb brings decades of financial leadership across high-growth tech and AI companies. Known for his rigor and thoughtful leadership, he joins Chainalysis after more than three and a half years at Productboard, where he served as CFO and partnered closely with product, go-to-market, and operations leaders to strengthen financial foundations, improve operating discipline, and support strategic decision-making across the business. Prior to Productboard, he served as CFO of data and AI governance platform Collibra for 4 years, and senior finance roles at RingCentral, Atlassian, IBM, and Taleo Corporation (acquired by Oracle).
Chainalysis is entering 2026 with strong momentum. Over the course of 2025 we accelerated ARR growth across both public and private sector, and made significant product investments, including leveraging AI to expand our proprietary crypto data advantage. Seb takes the helm at a time of transformation for the company: we’re building alongside the world’s largest government agencies and financial institutions, arming our customers with the enterprise-grade data platform and tools that meet their demands – from risk and compliance to investigations and fraud.
Internally, Seb will be a partner to teams across Chainalysis, helping us make smart bets, prioritize the highest‑impact opportunities, and turn our product roadmap and go‑to‑market strategy into a profitable, scaled business. His track record of collaborating across engineering, product, and sales will be central to how we operate and win together in this next chapter.
“Sebastien is exactly the leader I need on my team during this time of opportunity and transformation at the company,” said Chainalysis Cofounder and CEO Jonathan Levin. “A strong operator and a world-class leader with high-growth and public company experience, Seb will guide our investments as we work to expand our leadership position as the data platform for crypto as enterprises move on-chain.”
“Chainalysis is an integral part of the world moving on-chain, equipping its customers with the tools they need to make our world safer and our financial system more trustworthy,” said Sebastien Giroux. “It’s an incredible time to join the company, and I’m looking forward to working alongside Jonathan, the leadership team, and colleagues across every function to build a profitable, scalable business and help Chainalysis execute this next phase of growth.”
