Given the other posts, there's a mix needed, and a startup CEO might need to be very different from a scaling company CEO.<p>In a startup, who's on your team matters. Are you a two man show? You (the generalist) and your co-founder/CTO (techie)? The two of you alone probably don't have what it takes to promote/market your product after it's built. However, if you're good at managing teams and can pull in people who can fill gaps (marketing, sales, etc.) and coordinate all the people in the initial phases to make things hum. However, if you can't find these people, you may need to be kick-ass (a specialist) in biz-dev to get things going.<p>In a scaling company, your curent skill-set may be perfect. There may already be enough boots in your team to fill all the critical roles, and you, as a generalist can both coordiante AND help out in any one area, as needed.<p>At the end of the day, it comes down to this: your confidence in your self.<p>You're already a generalist, and though it sounds unintuitive, becoming a generalist is not something that's simple--people tend to become good at just one or two things (coders, carpenters, paineters, etc...). Do you have the passion for the idea? Are you willing to work hard to get from a startup phase to a growth phase? Given that you're asking the question above to a forum, you're probably already thinking about these questions--and these questions are good ones for you to ask.
