These web technologies quickly became a game-changer for our business. Lead generation projects that used to take a whole team are completely automatic now. We were able to segment traffic based on location, identify more prospects, and onboard more clients. I can't say enough good things about Ful.io
Doja Marketing/Defi Founder
Companies need an edge, and Ful.io provided that edge for us. We'd previously used BuiltWith, but the data and analytics capabilities of Ful.io were a better fit for us.
We used to manually upload contact details and other data, but it took way too long. We needed a solution that could automate the process and free up resources. Ful.io just works for us. Their technology is incredible.
Ful.io's apps and tools have completely changed the way we look at traffic and identify prospects. Before, our R&D team tried BuiltWith, then worked to develop our own technology. But with Ful.io, we can save both time and money.
