Even a midsize company wants SSO (which is $7 a seat through Microsoft) and don’t want to have to worry about onboard and off board users individually to every SaaS product they use

Any midsize company that would trust having their proprietary information like would be in one on ones would be a complete idiot to depend on a random website.

One on ones usually feed into reviews. What guarantees would their be that the site would be up in a year?

Interesting theory.

IRL: I could add whatever I wanted into my computer at most places I've worked, including multi-billion$ international companies.

Can you put your company’s proprietary information on any website? Sure I can put anything on my work computer.

If your company wouldn’t mind you putting details of your 1 on 1s on his website, do you mind just emailing me those notes?

Yes it would be kind of crazy to do that wouldn’t it?

Enterprise shouldn't be the bar for caring where you store your data. Just putting data anywhere needs to end.

Would you be okay with your doctor putting his notes on you in the website? Would you be okay with your accountant putting all of your financial data here?
