Business school may not provide the skills necessary for early-stage startups; practical experience and learning by doing are more effective.

Business schools are doing a poor job of preparing students to start tech companies, as observed by Michael Seibel.

As a professor at Harvard Business School, I find it concerning that many students applying to Y Combinator lack basic knowledge of core startup principles.

The perception that an MBA is a valuable credential in the startup world is misleading; many successful entrepreneurs do not have MBAs, and the real learning often happens in the trenches of startups.

To improve startup success, business schools should focus on creating environments that foster cross-pollination between technical and business students.

Students should be aware that not all entrepreneurship programs are designed to support their success, as some may accept teams that don't meet foundational requirements.

I recommend business school for those who can afford it, but graduating with significant debt can limit future opportunities and lead to poor life choices.

Many founders fail to recognize that most startups, including their competitors, are likely to struggle, and that the common outcome is that many will not succeed.

The belief that a business person or MBA is essential for a startup is not necessarily true; a technical founder can be sufficient.
