Julian Espérat is a Staff Engineer based in Lyon with 13 years of experience building web-first products and developer-facing APIs. He co-founded two startups (MailClark and Clubble) and led end-to-end engineering efforts—from product design to operations—before MailClark was acquired by Sendinblue (now Brevo). At Brevo he has driven Conversations, Inbound Email Parsing and Email Sync APIs and now architects solutions across CRM, Phone & Meetings, Conversations and AI Assistant teams. Comfortable operating in tiny teams, he combines hands-on implementation with system-level thinking and a focus on email and messaging workflows. His background in R&D and open-source CMS work gives him a pragmatic approach to maintainability and tooling.
