That said, the pricing worries me a bit. This is a tool we'd have to build on top of. Which means that if it disappears later because you went out of business (or just changed your pricing in some way that hosed us), we'd have a whole big, unexpected engineering project to rewrite our SSO.
And given that you're giving a hosted product away for free, it seems pretty likely that you will either eventually go out of business or change your pricing.
I know it sounds silly, but as someone who'll probably have to add SSO to my current project in the next 6-12 months, I'd be a lot more comfortable betting on you if you had a sustainable-sounding paid tier other than "free for now" and "idk email us." It'd certainly make it easier to pitch to the rest of my team. :)
I may not successfully convince you of the commercial logic here, but we are making a calculated bet that a generous free offering serves our long-term interests.
We're betting that this product will establish our credibility with developers and result in efficient distribution in the future. It's a pretty common commercial open source playbook not to monetize in the early days.
Thankfully, some subset of venture capitalists will happily underwrite companies with popular commercial open source products.
Please bear in mind that we're an early stage company. We will build more depth into the existing product, and we'll offer new products over time. We will charge for those new features / new products. It may take years to earn meaningful revenue, let alone generate cash flow, and we're fine with that.
