I would encourage you to join Microconf Connect, a Slack community of software entrepreneurs, where topics like this are discussed often: https://microconf.com/connect. Many of the old Microconf conference presentations are also on YouTube: https://www.youtube.com/c/MicroConf
This excludes all small software shops and single-man ops that do conventional desktop software. The community would easily grow 2x if the SaaS restriction is removed.
We used to cater to all software: mobile apps, desktop, WordPress, etc. and we still have many folks in the community who are non-SaaS. But the focus on SaaS was a spark that dramatically increased growth as it allowed us to optimize everything we offer (content, community, masterminds) on the specific problems SaaS folks face.
We don’t restrict folks who can join based on the type of software, so “restriction” is not the right word to use there. It’s just a focus.
And it was a great choice, allowing us to be the best in the world at what we do (rather than serving a broader market, poorly).
