Fiber AI Documentation
Fiber AI is a B2B sales intelligence and data enrichment platform. It gives go-to-market teams a single place to find the right companies and people, enrich them with accurate, up-to-date information — including verified work emails and phone numbers — and act on real-time signals about when those companies and people change.
In one sentence: Fiber AI helps you find any company or person, get their verified contact information, and know the moment something changes about them.
The four core motions
Almost everything Fiber offers maps onto one of four repeating motions:
| Motion | What it does | Start here |
|---|---|---|
| Search & Discovery | Find many companies/people by filters | companySearch / peopleSearch |
| Kitchen Sink | Resolve one (or many) entities from any messy identifier you have | KitchenSinkProfile / kitchenSinkCompany |
| Contact Enrichment | Reveal verified emails & phones for an already-identified person | syncQuickContactReveal, etc. |
| Live Enrich | Refresh a clean identifier to its freshest real-time snapshot | Profile/Company Live Enrich |
These compose naturally:
Kitchen Sink resolves the entity → Contact Enrichment reveals contacts → Live Enrich refreshes before outreach.
Where to start
Kitchen Sink
Resolve a person or company from whatever partial data you already have.
Contact Reveal

Ask in plain English; get a matching list of companies or people.

Filter 13M+ open roles by title, pay, and location. Count first, then pull rows.
