Our verdict
Fiber AI has quickly emerged as a credible alternative to established players like Clay or ZoomInfo in the segment of B2B data and AI prospecting. Its promise of ultra-fresh data, 4x cheaper than competition, combined with open APIs and hyper-targeted personalization, particularly appeals to hyper-growth startups and RevOps teams. Aggregating data from more than 50 providers (BuiltWith, LinkedIn, Gartner and others) ensures broad coverage, and claimed 80% open rates are impressive though to be confirmed in real conditions. The platform is younger than its competitors and still requires some technical maturity to be fully leveraged. But for modern outbound teams that want to industrialize prospecting with excellent value for money, Fiber AI is today a particularly interesting choice to evaluate in 2026.
