How can I sell my app but still have a say in its development?

Are you thinking of selling the app outright or just licensing its use? Licensing might allow for more options in retaining some control.

If you want to keep some control, consider only selling a portion of it—like 49%. That way, you're still a stakeholder and can influence key decisions.

You could always go the Software as a Service (SaaS) route, which might give you more control over how the app is used in the long run. If you sell it directly, though, you’ll likely need to relinquish that control.

You can definitely ask for that! Just be aware that whether they agree is another story. It all depends on how much leverage you have in the negotiations.

If you're selling the app entirely, it's really important to include any desire to stay involved in the contract. Just keep in mind, asking for a say in development might lower the app’s value since it complicates things for the buyer.
