AppSumo:
Post acquisition, the revenue coming in from AppSumo fluctuated anywhere between $300-$1000 per month for about 6 months. Then it started to steadily declined from there. Currently (about 1 year post acquisition) I'm only seeing about 1 or 2 sales per month come from that platform which only brings in about $40-$80 in revenue. Not ideal.
MRR Subscriptions:
In that same period of time, the monthly recurring subscriptions revenue went to $0. There were only about 3 real customers paying monthly, and they all cancelled their plans within months after the acquisition.
However, just last month I got our first net-new paid subscriber post-acquisition. I'm pretty sure this was sourced from running Google search ads, although it's tough to say 100% because our GA/tracking is pretty basic at the moment.
All of that said, our current total revenue is about $50-$100 per month when you combine our MRR with AppSumo.
