Technically correct but getting rid of someone at 11 months is their mistake not the employee. They should have evaluated at 3 and 6 months. Letting go at those points and not vesting seems fair enough. The company needs to sharpen their processes. I am guessing this is a startup founded by people who have never worked for someone else as this is commonplace process to have set up 3 and 6 month reviews, PDPs, and probably a tighter hiring process is needed too.
I'm willing to give leeway to a new company. Many founders, even those from companies that have these processes, might not fully understand the value of those processes until they're in the spot of needing them (like in this case).
