It depends entirely on the type of business you plan to create. Let's put potential businesses in three categories: 1) technical innovation, e.g. Google. If you want to go this route then a PhD program might be your best bet. 2) business model innovation, this is the most common type of entrepreneurship (outside of HN circles), think the Inc 500 list of fastest growing companies. You probably don't need an MBA for this and definitely don't need a PhD. 3) HN type of businesses, not necessarily technically genius, but at least one technical founder is needed. e.g. Facebook. Neither MBA or PhD, just do it now. Where can an MBA be useful? If you plan to grow through business development, i.e. deals, JV's, alliances. An MBA connects you to financiers more quickly than a PhD would and it definitely gets you talking their language. For example, running a search fund out of business school is definitely doable. An MBA is also very useful if you want to get a solid reliable day job in corporate America and eventually run or support corporate R&D or incubators. Most F100 companies spend more on R&D than the large multi-year VC funds do over a decade. From such a perch you can have a big impact if you've got the patience for corporate politics. This is the route I've taken and I can get access to top management faster than engineers who have been their for years and definitely faster than two guys and a dog. Of course, this is definitely trying in terms of patience. As for MBA support for entrepreneurship. It entirely depends on the program. That's just part of the due diligence you've got to do before applying to business school. Most top 10 business schools will get you in front of VCs faster than just about any other way and your competition will be nothing. As an MBA I would recommend most people who are reading HN to not get an MBA. It's not a bad degree, like anything it's what you make of it. But I can tell you that if you have the intellectual curiosity and the "get it done now" and "show me" attitude prevalent on HN, you're going to get frustrated very quickly with your MBA classmates and your corporate co-workers. If you've got the patience, great, but be forewarned, it's a tough road.
