Figuring out features, while not easy, is straightforward. You talk to customers, you talk to prospects, you look at the competition, etc.
What's hard is figuring out the story. What's the actual problem that you're solving?
I'm a business hacker and generalist, with expertise in go-to-market, business development, product, UX, M&A, customer experience, to name a few. Sometimes, when you're starting a company, you know you have a problem, but don't know where to start on a solution. I can probably point you in the right direction quickly, even if I can't directly solve your problem.
Thinking about joining a startup? Startups have a lot of risk. It's a good idea to assess the risk outside your direct span of control. If you're a sales VP, you want someone to look at the product. If you're an engineering VP, you want someone to evaluate the go-to-market.
