About Fiber

- Natural-language and structured search across large company, people, and job datasets
- Reverse email lookup plus contact enrichment, live fetch, and CRM-style enrichment endpoints
- Verified email and phone waterfalls with bounce detection and validation
- Real-time LinkedIn and company data retrieval for fresher enrichment workflows
So agents can…
- Build lead or candidate lists from partial information instead of exact identifiers
- Enrich signups, CRM records, or outbound targets with verified company and contact data
- Pull fresh people, job, and company signals into recruiting, sales, or market-mapping workflows
Listing decision
Why Fiber is listed
Fiber is a general B2B search and enrichment service that agents can call through APIs or MCP; its core data service enables agent workflows rather than operating as an autonomous agent.
