Timing. Relevance. Relationships.

Fundz is the only platform that reads more than a dozen real‑time signals all day, every day, so you know about new funding, new executives and new contracts within minutes of them happening, not days or weeks later like the databases you’re used to. It then combines the signals on each company, scores every company against what you offer, and weaves in your own network, so you discover new accounts first and work existing ones better.

Each morning you get the ones worth your time right now: who to reach, why now, and who you already know there. Now it answers in Claude too: ask for today’s leads, then write the note in the same window.
