Subsignal is like having a research team that never sleeps. Found 12 qualified leads from Reddit in one day. This is a game changer for outbound.

It's actually unbelievable how good Subsignal is. It replaces manual prospecting. The ability to "chat with the signals" to understand context is pure gold. There's no going back.

The two AI tools I use most often right now: - Subsignal - Clay Both are 10/10. Subsignal has solved signal detection for me and Clay has saved me dozens of hours of enrichment.

I don't think I've ever gotten more thanks from people recommending an app than I have for @usesubsignal. Everyone thinks they have a good prospecting tool, but it's only once they use Subsignal they realise what they've been missing.

Subsignal is one of the best made "AI" apps that I've used this year. If you do any outbound sales, this is a gamechanger. It finds signals in all that noise for you. It's minimal, fast, with no setup. It. just. works.

Been using subsignal.ai a bit lately; it finds the best buying signals of anything I've tried so far. Not sure how they did that.

Subsignal is so good. I hope they introduce a marketplace of one-click integrations. I got use cases! :)

I get uncharacteristically excited about checking my feed now Why? Because the payoff is seeing @usesubsignal really work its magic and surface incredible leads seconds after they post
