There's no simple answer to the question of whether angel investors prefer startups' founding teams to be from Harvard Business School. Some angels may place a high value on a team's pedigree, while others may be more interested in the team's skills and experience.  That said, there are a few factors that may make HBS-educated teams more attractive to angel investors. First, HBS students tend to be well-rounded and have experience in a variety of fields. This can be helpful in a startup environment, where team members often have to wear many hats.  Second, HBS graduates often have strong networks, which can be helpful in getting a new business off the ground.  Finally, HBS students are often groomed for leadership positions, so they may be more prepared to take on chief financial officer or chief marketing officer roles within a startup. Ultimately, it's up to each individual angel investor to decide what type of team he or she prefers.
