There is a new tool called monid.ai , I tried over the weekend using my ICP, it find signals from the internet ( linkedin, reddit , etc )
After trying multiple tools , didn't find one that I really liked until I landed with Monid.
I hooked up with my Apollo + Codex, and told my codex agent to spend as little as possible. It ended up spending less than 1 $ for 100 leads.
If you want I can give you a small walkthrough Andrea G.
