Fiber AI

Fiber AI is a people and company data platform delivered primarily as an API for AI agents, sales tools and recruiting products. It provides company and contact search, reverse email lookup, verified work emails and phone numbers, CRM enrichment and live fetches of LinkedIn profile, company and activity data. The same Fiber API is reachable through five surfaces: an MCP server, REST APIs, AI plugins, OpenFiber and SDKs, alongside webhooks, a HubSpot integration and the Fiber web interface. It suits developers building AI SDR or recruiting tools, teams wiring prospect data into coding agents, and outbound sales teams that want enrichment inside their existing stack. The MCP server has several endpoints: V2, which uses an API key and is recommended for most projects, and V3, which signs users in with OAuth and connects to Claude and ChatGPT as a custom connector. Typical prompts include finding SaaS companies of a given size in a city, locating heads of sales in a sector, matching a GitHub or X handle to a LinkedIn profile, and revealing a verified email and phone for a profile. Pricing is published and credit based, with credits charged only for successful calls. Prospector costs $300 per month for 15,000 credits. Growth costs $900 per month for 50,000 credits and adds priority support in a dedicated Slack channel and double rate limits. Enterprise costs $2,400 per month for 150,000 credits with custom rate limits and custom API endpoints. Each plan includes a seven day free trial, and yearly billing saves 17 percent. Bulk API Search, for products that embed search of companies, jobs and people, costs $2,000 per month for one million search credits, and larger custom plans are negotiated directly with the company.
