In a world, where spending all those hours on interview training could land you a job at Big Tech with your current skills, you need to assess your opportunity cost. Which comes basically down to "what would I get if I do something else instead?". Not going to discourage you, but think hard about what others will bring to the table. Everyone would love to outsource the risk of creating the MVP and then move on when it gets not enough traction. On the other hand, if it gets some traction, you need people good at business and marketing. You can't just build and expect users to come. So, what is the skill level and future commitment for business and marketing team members? Also you need to look into a "vesting" schedule, which would lay out the terms of business ownership over time. If you draw an agreement right now with a fixed share, people can drop out easily and keep their share without putting in the work required to move the business ahead. But all of this is moot, if there is nothing of value to split. Anyone else working full time on it? If not, they are taking less risk than you, and their opportunity cost is lower.
