Checked away from the directory entry. Neither line below comes from the company's Y Combinator page.
We develop our own AI models for audio and video generation, editing, and understanding. They power Descript's video editing workflows.
The title and description the site itself served, answering 200, after redirecting from https://lyrebird.ai/. 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. Hacker News is not us, and nothing above is our opinion of the company.
I started lyrebird.ai which pioneered voice cloning technology. Lyrebird.ai was sold to Descript, where I led AI for 5 years and shipped a bunch of AI features. Additionally, I have been serving on the board of Descript after lyrebird acquisition (pre-Series A, until now in 2024, post-series C).
Founders, titles and bios as the company published them. Photographs are our own copies of the ones on that record, so they do not break when the original link expires.
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 Lyrebird: 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 (descript.com), and from Hacker News, where 5 threads met the matching rule stated beside the count.
