While most marketing tech stacks scream for attention, Leadinfo operates in the shadows—literally. This Dutch-born platform doesn't just track website visitors; it unmaskes the companies behind anonymous traffic, turning invisible clicks into qualified sales pipelines. With 72 employees and $10.4M in revenue, they've built a quiet empire on the premise that knowing who visited is more valuable than how many visited.

"They're not selling visitor analytics—they're selling the moment a sales rep can finally say, 'I know exactly who you are.'"

The company's tech stack tells a story of pragmatic modernity. They use jQuery alongside Tailwind CSS and Bootstrap—a hybrid approach that prioritizes stability over bleeding-edge frameworks. The presence of PWA (Progressive Web App) support and Priority Hints indicates they're optimizing for performance, while Lazy Loading suggests a focus on user experience. This isn't a startup chasing tech trends; it's a product team building for reliability.
