What is Fiber.ai?
Fiber.ai is a real-time people and company data API covering 850M+ professionals, 40M+ companies, and 30M+ job postings, with search, enrichment, and monitoring endpoints. It is not a recruiter-facing search tool; it is the live data feed a build team plugs into a custom sourcing or BD pipeline to keep candidate pools and prospect lists current as roles and companies change. Its API-first design, including reverse-email lookup and profile enrichment, makes it a clean fit behind an internal tool or an enrichment waterfall.
What are Fiber.ai's key features?
People and company data via API at scale: query 850M+ professional profiles and 40M+ companies programmatically to build sourcing lists and BD target lists inside your own workflow, not a search UI.
Reverse-email lookup and profile enrichment: resolve a person's current company and role from an email, or enrich a partial record - endpoints Fiber highlights as differentiators versus other providers.
Work and personal contact data: surface work emails for BD outreach and personal contact details for candidate outreach, with verification depending on the query.
Job-posting and hiring-event monitoring: webhook alerts on job and hiring events let a pipeline react to movement automatically instead of re-running a static search.
Native MCP support: connect Fiber to Claude, Cursor, and other MCP clients so an AI agent can run searches and build lists directly.
How do recruiting teams use Fiber.ai?
- A technical operator adds Fiber.ai to a Clay waterfall for work-email and mobile lookups, layering it alongside other providers to lift coverage on records a primary source misses.
- A build uses Fiber's continuously refreshed company search to auto-add prospects matching an ICP as those companies start showing hiring signals, without re-running a search.
- A recruiting-ops function uses Fiber's reverse-email lookup to identify a candidate's current company and role from an email surfaced during sourcing research.
- An AI sourcing agent calls Fiber over MCP to pull and enrich candidate profiles mid-task rather than exporting a static list.
Who is Fiber.ai best for?
- Recruiting or BD teams that need programmatic access to people and company data rather than a manual search interface.
- Builds where sourcing, enrichment, or ICP logic pulls records directly into a custom workflow or internal tool.
- Teams running a waterfall who want reverse-email and partial-search endpoints most providers do not offer.
What are Fiber.ai's pros and cons?
Pros
- Real-time data across 850M+ professionals, 40M+ companies, and 30M+ job postings, with continuous refresh (per Fiber).
- Reverse-email lookup and partial-search endpoints Fiber positions as differentiators versus other data APIs.
- Work and personal contact data, so outreach can run on either side depending on strategy.
- Webhook alerts on job and hiring events for automated monitoring.
- Native MCP support for AI agents to run searches and build lists autonomously.
Cons
- API-first; connecting it to a CRM, ATS, or outreach tool needs a developer, not a point-and-click setup.
- Credit-based, usage-dependent pricing means cost can climb with large search or enrichment volume.
- No built-in outreach or sequencing; you export data to a separate CRM or email tool to actually contact anyone.
- Not certified GDPR-compliant, which matters for EU-candidate data handling - confirm your own basis before processing.
