CEOs with formal business backgrounds are really good at squeezing technical types in negotiation. He might be betting on you being so tired of the company you'll take the lowball and running. But you still have some leverage given your ownership, and it sounds like your relationship hasn't completely deteriorated. I wouldn't burn the bridge yet.

€60k seems pretty low for half of a company making €600k/y and is about to get a €1.3M grant. I'd ask for the following:

1. €150k for the buyout 2. Some percentage of the incoming grant, since your work clearly contributed to its approval 3. Clear termination of any claims to your IP/copyright

It's not the best deal that they're offering but it's not a ripoff. Try to salvage whatever good faith you two have left, get everything in writing. I think you can both come out of this satisfied.

They are not "making" €600k / year. The had some one-off grants. This is not ARR.

The €1.3M grant has not landed and you can't use that. Even if that lands, it's still not ARR.

[skeeter2020]

this. The value of a company in this scenario is ARR, discounted sales pipeline, IP, and goodwill. It's likely to be very low for a departing founder, because it's almost all goodwill at this stage which for tech startups is essentially "the perceived ability of the founders to build something that eats the world", which by definition is a going concern he won't be part of.

[biphasic]

that is correct. The company needs to build a product more or less from scratch at this point
