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.
Prior to joining YC, Veniamin was a PhD student at Princeton where he worked on large language models. His work is widely cited and covered by the media. Before that, he did research in Toronto, Switzerland, Germany, and had a brief stint at a Ukrainian start up building interactive tables.

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 Preseen: 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, and from the company's own site, read directly on 2026-09-27 (preseen.com).
