Signals that move deals. Not lists that go cold.
Both Rembrandt and Apollo aim to help sales teams find and engage prospects. But they take very different approaches—and deliver very different outcomes.

Apollo is built for scale.
It hands you a giant list and a “maybe” tag.
Everyone’s hitting the same accounts, with the same pitch, at the same time. You’re just noise in the inbox.
Rembrandt is built for timing.
We don’t sell leads. We track account movement — using your own signal logic — so you know exactly when and why a company’s warming up.
No more guessing. No more spray.
