About Keryx
The herald for the right people.
Keryx is the writing surface for hiring teams. From the first intake to the last rejection letter, we draft, check and archive every message you send to candidates — in one voice, and audit-ready.
Why we built it.
Hiring writing is where companies quietly leak trust. Vague job posts, recycled outreach, boilerplate rejections that read like they were generated in 2011. Every message that goes out shapes what candidates think of you — and most of them are written under time pressure by people who'd rather be doing something else.
Keryx exists so hiring teams can write clearly, kindly and quickly — without cutting the corners that matter.
What we believe.
Craft over volume.
A hiring team that sends fewer, better messages hears back from better candidates. Keryx defaults to fewer, better.
Deterministic where it matters.
Herald Check is rules-based, not a black box. Same draft, same score, every time — so you can defend it.
Inclusive by default.
Bias, gendered phrasing and vague seniority language get flagged before a candidate ever sees them.
Made for teams, not lone recruiters.
Brand voices, shared templates and an audit trail keep a hiring team speaking as one company.
