Hi everyone. I wanted to get some framework to think about this situation I am in. Hoping I can get some perspective from your experience.I have started a start-up whose MVP is out currently and we are testing every week with users and getting good insights on the problem/solution space. I am currently a solo founder and obviously want a co-founder in the not so distant future.During the journey of putting the product out there and generally talking about the problem in public, I encountered this person (lets call them "P"). P has good insights on the problem area and they have been a product person with significant experience (decades).They feel quite passionate about the problem space. Our insights on the problem, mission for the company resonate quite well. They have also been thinking of starting up in this space for a number of years (but haven't yet).We started doing sprints together where they opined (advised) on the product aspects, sat with me on user interviews and we brainstormed different aspects together. Their inputs have been very useful generally. We have discussed how we can work together. They envision their role to be that of opining on product roadmap, features and direction based on insights on data and user testing given their deep empathy with problem and expertise in product field generally. They also have expertise in team, culture and company building - that they expect to contribute towards as the company grows.They have a number of side things too - like their own consulting business so they will be devote 7-9 hours per week towards this and maybe going to 20 in the future.I will be doing the heavy lifting of building, growth, project/product management (running sprints, delivery etc), customer support, logistics of the product itself, hacking way through things etc. Now these seem to be a lot of tasks on my plate but idea is to get another co-founder onboard (or employees depending on how this goes). I am currently working 40-50 hours per week on this and doing all the execution. As the start-up matures, I will also transit completely full time on this (>50 hrs).Now P wishes to be co-founder in this relationship with double digit equity (less than 50% though), whereas I think this is an advisory role (with single digit equity, but more than what FAST advocates). Which is where we do not agree - as P wishes to have a founder's say in company's decision making and future. And I believe the level of contribution that we have discussed is not in line with the equity ask.Have you encountered or been in such a situation and what is the best way think about it?I would really appreciate your insights and help. Thank you.
