The best way to reach humans instead of spam folders. Deliver transactional and marketing emails at scale.
The title and description the site itself served, answering 200. Not a cached copy and not the company's directory entry — what was live when we asked.
Counted only where a thread links to this company's own site, announces it by name on that forum, or names it beside its own Y Combinator batch. A thread whose title merely carries the words is not counted — a name is not an identifier. More may exist than the one page of results read here. Hacker News is not us, and nothing above is our opinion of the company.

No investor is drawn from a Form D — the form states how many invested and never who. The one investor on this graph is named because a batch has exactly one.

If you're behind Resend: acceptance into a YC batch is one of the few weeks a young company gets looked up by people who matter — investors, other founders, press. FoxPlug turns the commits, deploys, and releases you're already making into that story automatically, so anyone who looks finds something current. GetFoxChat puts a guide on your own site so the people YC's own page just sent you don't read one line and leave.
Sourced from the company's Y Combinator directory entry, from the company's own site, read directly on 2026-09-27 (resend.com), from the public GitHub account that record links to (resend), and from Hacker News, where 9 threads met the matching rule stated beside the count.
