Searching for a small business to buy and run instead of taking a more traditional post-MBA job like consulting is an idea that we’re seeing catch on at top business schools. At the Harvard Business School, for example, the number of MBAs who decide to look for a business to acquire right after graduation has gone from less than a handful a decade ago to more than a dozen, and in an occasional year, twice that amount. Stanford’s most recent study of search funds also reports a record number of active search funds. Still, we often wonder why more students don’t follow the entrepreneurship-through-acquisition path.
