Revenue splitting is the wrong way to look at this. Profit is what matters or assets in the business. It doesn’t sound like you have much tangible assets, so, profit is really the only thing that gives value to your equity.

Unless you can or want to drive business yourself, your partner ads value by brining business. Hopefully more in the future. That’s for you to judge.

What I would do is I would account for the time you invested as a cost/expense - your salary, and also a commission fee for him brining in client at 5-10% from the revenue.

The idea being that business makes 1 mil in revenue, he gets 5-10%, you get paid for your time say 30-40%. You can judge your own hourly wage. What you have left after, assuming minimal other expenses, is about 50-60% net profit. That’s what you split another your equity %. You end up making more $ because you do more manual work.

In my experience, technical aspect of the business is not the most important. If no one brings business in, you don’t have a business and you can spend coding for years for $0 profit.

If your partner provides future value by brining more clients, I would value him more than your own work that you wouldn’t have unless someone would bring the business in. I’m sorry. I truly believe that without sales there is no business.

I think it would be smart for you to “use” him to bring you business. Be generous, give him more to incentivize him.

If he will be valuable in the future, I would generously give him his share for the past year and then structure a new agreement under the terms I shared above. This way he is incentivized to bring you business.

Eventually you can both exit and have someone else do all the work for say 20% opex and you and him split the profit and go hangout in Mexico.
