Read away from the record, per side. A side with nothing here is a side where nothing answered — the space is left empty rather than filled from the other one.
Conifer
Conifer routes to the Pareto frontier: the cheapest seat that still clears the work. Name a model and that model is served.
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. Hacker News is not us, and nothing above is our opinion of the company.
Nebula Security
NebuSec builds Nebu, an AI security platform for continuous code and cloud protection, backed by researchers who find zero-days in Chrome and Linux.
