You sound like a talented person with a lot to contribute to the company. You're going to help build a great product, and if you combine that with the talents of other people you'll build a great company. That last part is the important part. A company is MORE than a product. Do a google search for Steven Blank business canvas. Product is just one column in the whole thing. It takes a lot of work to build a good product, and you'll want to best person you can get for it (sounds like you're him!) but at the end of the day, you will also need someone who is going to help get it sold. You'll need a sales team, a marketing team, relationships with partners, you'll need all sorts of non-product related things. They're necessary. Products don't sell themselves. They just don't. It doesn't sound like you have any experience building a sales pipeline, marketing, or business in general. Your CEO is going to work on those things so you can put your effort on a great product. If you don't think he's up to the task, maybe you need a new guy... but don't diminish his equity. He has an important job, he deserves as much.
