Director | SaaS GTM Leader
"Working pretty nifty compared to Snov.Io, Price wise it does give a fair shake, and IMO better Interface since It's google sheets. Snov.io does have more flexibility with extra options, but a lot of those I don't even use since they are not flesh out. We will see how this performs over time."
