The most straightforward model, and where we are already making some money, is running a Convox as a managed service.
In this setup you and your team get Convox API keys. Convox installs, runs and updates everything for you in our accounts. You get a monthly bill that's your AWS resource costs plus a percentage to Convox for management.
We will be tweaking this model to sell packages so bills are really easy to understand.
Some other experiments we're doing...
We sell support packages and professional services for app setup, migration and custom feature development.
We have a per-seat model for productivity features. Private GitHub repos and Slack integrations are $19 / user / month. There are more closed SaaS tools like this coming.
Infra is trending to commodity prices industry wide.
We'll be selling SLAs, support, productivity tools on top of that infra.
You'll get a cutting edge private platform without hiring and managing your own devops team to build and maintain it.
Open source users will help grow the user base and make the platform better without us running a freemium platform.
