Technographics, Lead Intelligence & Web Insights
Founded in 2021, at Ful.io we help sales and marketing teams stop guessing and start targeting with precision with our technology profiler & lookup tool.

Our engine scans and tracks hundreds of millions of websites, revealing key technographic signals across all major and niche tech stacks, seprated in categories like eCommerce, CRMs, analytics, hosting providers, Content Management Systems, Payment gateways and many more.

Along with the Lead Intelligence we offer bulk lookup, allowing you to upload a list of websites and get complete technographic details, including contact information.

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.

We're always looking for new ways to boost our advertising efforts and analyze websites to improve our processes. Ful.io has been a perfect partner throughout. We've been able to discover more valuable data on prospects than we ever did on our own.

Any ecommerce platform not using Ful.io's technologies is seriously missing out. The crawling tool at Ful.io is the best we've used so far. We love that you can pull it up right in the Chrome browser too. Technologies, contact info, the speed we can draw in new clients now... Ful.io is amazing!

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.

Being able to quickly identify the software and security tools a website is using helps us assess risks and provide better recommendations. Ful.io’s technology profiling is both powerful and incredibly easy to use, which is exactly what we needed. Ful.io just works for us. Their technology is incredible.
