Sounds like a powerful service. What have you done to market it and find customers?
We also did a little bit of content marketing (Reddit, Indiehackers) which resulted in ~$2k MRR. We should normally hit $10k MRR and will launch a v2 of the site pretty site (right now it is just a landing page that I created in 5 hours to launch ASAP & let the market decide if our productized service was worth it!)
