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 five core motions
Almost everything Fiber offers maps onto one of five 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 |
| Trackers | Get alerted when a tracked company or person changes — funding, headcount, job moves, and more | Tracker |
These compose naturally:
Kitchen Sink resolves the entity → Contact Enrichment reveals contacts → Live Enrich refreshes before outreach.
Trackers run across all of them: once you know who matters, watch them and get told the moment something changes.
