After a marriage and a divorce I can expand on this (marital lessons reframed for business though).

There's a second question to ask: how often do you fight?

If you are generally in alignment but disagree sometimes / occasionally, that's good. If you seem to disagree most of the time, that's a problem.

Other specifics I'd look at:

- are you aligned on the fundamentals? (e.g. B2C vs B2B)

- do you fight the same way? If one of you prefers rational discussion and the other prefers combative, whoever-sticks-longest-wins then it's going to go poorly

- how do the fights end? "ok, after thinking about it, I think you were right about XYZ" is very different from "fine, whatever. I'm tired of arguing."

- do you resolve issues and come to agreement or do the same topics come up again and again?

- after a conclusion is reached and a plan is put together, do both parties fulfill their pieces of it reliably and on time?

One very simple way to avoid issues during fights is the 'I statement': "I feel my opinions get ignored a lot..." is a lot less escalation-inducing than "You always ignore my opinions".
