Anh-Tho Chuong is the CEO and Co-Founder of Lago, the open-source billing platform developers love. Lago powers companies like Groq, Together AI, and Mistral AI, and has raised $22M from leading investors including FirstMark, SignalFire, and Y Combinator. A strong advocate for open-source and extensible infrastructure, Anh-Tho also invests in B2B SaaS as an angel and fund LP. Before founding Lago, she helped scale Mailjet (acquired by Mailgun), Weebly (acquired by Square), and $5B fintech Qonto.
Driven by her frustration with the complexity of in-house billing systems, she launched Lago to help software companies grow without revenue bottlenecks. With real-time usage metering, a developer-friendly API, and an intuitive UI for business teams, Lago makes usage-based pricing straightforward—freeing engineering teams to focus on building great products.
