It won't be today but my goal is to earn a place on your org's approved list one day and win you as a customer :-)
Relatedly, I've had a few requests for a self hosted version already and will be offering this very soon as a priority. If that'd solve the issue also, please email me at davnicwil at gmail and I will update you when it's available.
I hate to be mean. But you never will earn a place as a one man unknown developer to be an offering at my company and be a place where we put all of our information for both confidentially reasons and we wouldn’t trust the long term viability of your company.
We already use Lattice for performance notes, peer to peer feedback and it’s a place where we put notes for our 1:1s. It integrates with Slack to remind us to enter topics before the meeting, etc.
Even with all of those objections, you won’t get anywhere in corporate America with your product unless you offer SSO. It’s not that hard to do.
I have recommended a one man SaaS once in my career to something that was critical to what I needed for a large company critical initiative. But we got lawyers involved and negotiated our own instance and the code be put in escrow with a third party that we would get access to under certain circumstances. We were going to be 70% of his post sign in revenue and growing.
