Fiber AI is a platform for finding and verifying B2B contact data. It uses AI to deliver more accurate results than LinkedIn and aims to be more cost-effective than tools like Clay, Apollo, and ZoomInfo.
Verified contacts with a guarantee
Fiber AI provides validated email addresses and phone numbers with a 0% bounce guarantee: if emails don’t deliver, you get a refund.
- Verified emails and phone numbers for outreach
- Coverage of 40M+ companies and 850M+ people
- Database also includes 32M job postings
AI search and research agents
The platform uses AI-powered search and AI research agents to surface leads that may not be available through standard tools like LinkedIn Sales Navigator. Data is continuously refreshed, and multi-step “waterfall” validation helps reduce errors and outdated contacts.
For sales teams and developers
Fiber AI works for sales and marketing teams as well as developers who need data access inside their own systems.
- API for integrating contact data and search into CRMs, products, and internal tools
- Supports scaling cold outreach while improving conversion and lowering cost per lead
