Yeah, spin up a bunch of modules for different ecommerce platforms that integrate with your platform. See if your ex-co-founder will be your first customer, if they still need the service the software provided. It might actually turn out to be a fruitful relationship to have such a close feedback loop for shaping the software into something customers want. Just be careful not to accidentally build them a custom plugin only useful to them specifically. Charge them accordingly if they ask for big features. A lot of customers to SaaS products are willing to help fund feature development as custom work in addition to the recurring payments..
