I wonder if there's room for a software deployment model for SMBs. Create a GUI on top of Ansible so customers can configure their build, build/deploy a software tarball to a VM, and provide data and code migration tools to your local community colo - all open source. Company offers upgrades, security patches, operations/customer support, and occasionally new features - no mandatory subscription fees, no forced cloud-native stack, and no VCs demanding 20x returns. Something friendlier to programs than Microsoft Excel and XP, and friendlier to SMBs and end users than Slack and G-Suite. Almost like a neighborhood Red Hat, with shims for toy shops, bakeries, and bookstores.
I think a bootstrapper could pull it off, or a small team of two/three funded by a friendly angel.
