Up until the MVP is developed there's really not much else to do. As a guy that straddles the line between "tech guy" and "business guy" (I've done both of them), my opinion is that there is a lot that can be done before the MVP is developed. In fact, if the business guy isn't out validating what the tech guy is building from day one, it is almost guaranteed the MVP is going to be wrong and/or it is going to land with a resounding splat. As the business guy, my job was getting out, meeting with potential customers, understanding what they would buy, what they wouldn't buy, and why. My job was getting early interest in our idea that could translate into (eventual) early use of the product. My job was making sure we understood who else was in the space and how we were going to differentiate our product. In short, if you practice "throw some code out and start selling", you are going to have a really hard time getting traction.
