Resend reports 4.3 million users and $10 million in annual recurring revenue
The developer-focused email platform has reached $10 million in annual recurring revenue with 120,000 paid customers. Founder Zeno Rocha says the company has surpassed SendGrid in SDK downloads while building its own infrastructure to improve deliverability.
Resend, an email infrastructure platform founded by Zeno Rocha, reported powering 4.3 million users and 120,000 paid customers as of November 2026. The YC Winter 2023 company has reached $10 million in annual recurring revenue, with notable clients including Warner Brothers and HBO. Rocha stated that Resend has surpassed SendGrid in NPM SDK downloads, currently exceeding SendGrid's volume by more than double, although SendGrid still handles higher total email volumes due to its enterprise client base.
The company is transitioning away from relying on AWS SES to build its own underlying infrastructure. This move allows Resend to manage IP blocks and traffic control directly, aiming for better deliverability and observability. Rocha emphasized a 'trust by default' philosophy for user onboarding, contrasting this approach with competitors who require lengthy human verification processes. He argued that Resend's developer-first approach and lack of friction are key differentiators against legacy competitors like SendGrid and MailChimp, which he views as neglecting the developer persona. The company maintains a free tier to support developers, citing its own origins in using free tools like Heroku.
