Data coverage:
40M+ B2B companies, 850M+ B2B contacts, 30M+ job listings. B2B database with emails, email addresses, phone numbers, mobile numbers, direct dials, and contact information sourced from 100+ providers including LinkedIn, Crunchbase, BuiltWith, and more.
We help AI sales tools, AI recruiting platforms, AI recruiting tools, recruiters, recruitment platforms, sales automation tools, recruiting automation, lead enrichment products, email enrichment tools, phone enrichment services, data enrichment platforms, lead scoring tools, and GTM teams get the B2B data, contact data, email data, phone data, lead data, and prospect data they need via simple, affordable data APIs, data feeds, and webhooks.
We have B2B company data on 40 million B2B companies and 850 million B2B contacts (i.e. B2B database), sourced from dozens of data providers (i.e. think sources like BuiltWith, Crunchbase, LinkedIn, ZoomInfo, SemRush, Apollo data, and more). This allows you to precisely segment your audience by the companies you care about and exclude everyone else. Our audiences are dynamic (i.e., account based marketing, account based sales, ABM like Clearbit, 6sense, Demandbase), meaning we continuously look for prospects matching your targeting criteria and add them to your audience to run automated outbound sales sequences. This automates manual workflows you might be running on platforms like Clay or Persana. You can also create an audience once based on intent signals (i.e., GTM or go-to-market signals, sales intelligence) and put your outreach on autopilot.
This is why RevOps, sales, growth, recruiting, and outbound teams choose us to power their AI SDR platforms (examples of these platforms that could use Fiber AI include artisan ai, 11x, amplemarket, reply.io, unify gtm, penguin ai, regie ai, aisdr, artisan sdr, outreach io, and warmly ai - many of these have used or currently use us), existing lead databases (email enrichment, bulk email finder, or phone enrichment tools like apollo, zoominfo, leadIQ), and contact enrichment tools (clay, persana ai) that promise automation and enrichment but deliver poor results.
