How do I hand my SaaS product to a co-founder who is buying me out over time?

A gradual buyout means you hand over responsibility in steps while the business keeps running. Start by mapping the product: the code and where it is stored, the servers and accounts it runs on, the third-party tools, the customer data, the billing set-up and the support routine. For each, note who now holds access and who will hold it after each stage.

Then connect the handover to the payments. Many founders tie each transfer of duties to a milestone, so that the co-founder takes on support first, then releases, then billing and customer contracts, while you keep an approval role until the final stage. Ask your lawyer to put the milestones, your remaining role and what happens if a payment is missed into the agreement.

Write down the knowledge that only you hold: why the system was built the way it was, known weak spots, the customers who need special care. Record walkthroughs. Look after customer data carefully, and ask your lawyer about privacy duties during the transition. Agree also how the product’s name and branding will be used afterwards. Finally, plan how customers will be told, and keep a set of regular check-ins so small disagreements are settled before they grow.

Key takeaways

• Map code, servers, accounts, customer data and billing, and who holds access to each.
• Tie each transfer of duties to an agreed milestone.
• Record the knowledge only you hold, with walkthroughs.
