“It's like a companion that does a lot of thinking for me, highlighting the contacts that are important for the team to reach out to, without them having to think about it. It provides signals to the team without them having to go three layers deep to try and surface in themselves, saving them time and making them more effective”

“Cognism’s data quality was about 30% better than everything else we were looking at.” “With ZoomInfo, the data quality in Europe isn’t what we would need. With Lusha, we get something, but when we dial, it’s not at all where we would expect it to be.”
