Resend (YC W23) raises $18M Series A (opens in new tab)

Hi HN! I'm Zeno, founder of Resend (YC W23).

I'm going to keep this link open all day, so feel free to ask any questions.

We're building a modern email sending platform for developers.

We've been laser-focused on giving developers a world-class DX all the while specializing in actually landing in inboxes.

It's been only 18 months since we publicly launched Resend. Now, more than 200,000 developers have signed up. Some of the biggest brands in the world, like Warner Brothers and Decathlon, and fast-growing startups like Braintrust and Raycast use Resend.

Our open source project, React Email, just crossed 300,000 weekly downloads on npm, 14,000 stars on GitHub, and more than 130 contributors.

Resend just raised a $18M Series A led by Andreessen Horowitz, and we're excited for the potential this new round of funding provides.

Thank you to those who created an account last year or this month.

Resend looked kind of cool and thought of using it. There was a security incident a while ago that had me think it again.

From the very beginning, Resend’s DX was superior and the messaging told me as a developer, “We understand you.” Over the years, that first impression has been proven true again and again. Congrats!
