Coresignal Data Search

Coresignal is doing something that should've existed years ago—letting you build B2B lead lists by just talking to it. Type "find me CFOs at fintech companies in San Francisco with 500+ employees" and boom, you've got a list. No SQL, no weird filters, no exporting from LinkedIn and cleaning up the mess. That's the game they're playing.

Here's what makes them actually interesting: they have data on hundreds of millions of jobs globally, plus company data and employee profiles at scale. We're talking real-time public web data, not stale databases that haven't been updated since Q3 2023. They offer Company API, Employee API, and Jobs API so you can build whatever you're building—AI training pipelines, sales intelligence tools, recruitment platforms—without having to scrape the entire internet yourself. They've positioned themselves around the "ethically sourced" angle which is refreshing when most data companies just shrug and say "well it's public."

The team—Lev Kerzhner, Lien Chueh, Laurynas Gruzinskas, Lukas Racickas, Karolis Didziulis, and Carmona Serrat—is running things out of Lithuania, which is becoming an unexpected powerhouse for data infrastructure companies. If you're building anything that needs B2B signals at scale and you're tired of paying through the nose for outdated data, Coresignal is worth a look. They're clearly playing the long game in the HR tech and sales intelligence space.
