Non-technical founders: what do you do while you wait for the MVP? (I will not promote)

I’m a non-technical founder for my company with domain expertise. Up until now, I’ve been primarily building out our product concept, use cases, and core features with my CTO co-founder, and talking to hundreds of ICPs to validate & sell the ideas. We built the prototype, got more feedback, iterating, and now in the process of building the MVP. Besides continuing to sell the idea to potential customers and taking to ICPs, what else can I do to optimize the time for my company as a non-technical founder waiting for the MVP?
