Gbaldraw is an n-user drawing app. It contains a variety of drawing tools, more are being added over time. It also has a chat and private rooms. I'm seeking advice for turning this into a successful business or a potential buyer. I'm also seeking advice about monetization models. It currently allows buying ads for $1/month. It is powered by Redis and Ruby on Rails 6 with WebSockets. I have closed 58 issues on it and only 14 remain. It is a powerful alternative to Microsoft Whiteboard and contains some features missing from that app. My intention is to provide collaborative drawing software for artists and a whiteboarding solution for teams. It is a fully collaborative real time software (not turn based.)
Also please be warned that the main (global) canvas is unmoderated. However if you see something you don't like, you can erase it yourself.
