If you have a plan to move-over to next venture after the successful establishment of company in future, Be clear about it.
I just started a new physical business, and this is what I shared with the partners;
I informed them about my intended exit plan with gradual transfer of my responsibilities via new hires and training them. I also clarified my position after exit that my exit from business operations does not indicate in lower future benefits.
After sharing this, Ask if they have anything like that in mind.
Other matters that needs to be discussed includes, clarification of responsibilities, the vesting period, agreement for the case of dispute and who will own what, etc.
make sure to get it documented legally(I made a mistake here for said business and I am regretting it).
