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.
I don't know Lattice so I would not use it.
Those would have been a great starting point as well! But maybe we'll see them later.
