I understand that a Profit Sharing Agreement would be the solution. You could negotiate a formal written agreement that guarantees you a percentage of future profits, even if you reduce your active participation. This could be a fixed percentage of profits or royalties. The most important thing is to make sure you have everything in writing and that both parties agree. It would be advisable to consult with a lawyer specialized in startups and entrepreneurship to help you structure an agreement that protects your long-term interests. This will avoid future misunderstandings or disputes. Also consider that 50/50 companies are the most difficult to manage in situations or conflicts between their shareholders, which can cause paralysis in the company's operations. Good luck.
