As interest in entrepreneurship through acquisition (ETA) has increased over the years, so has the growth of investors interested in backing acquisition entrepreneurs.


But finding the right investors for an acquisition is still a major challenge for operators seeking to buy a business. How do you know which investors are actively deploying capital into your target's industry and geography with the right size of check required for your deal?


In this year’s top investors list, we’ve gathered investor profiles from across the industry—from individuals to syndicates, private equity funds to family offices—and presented them below with key details for each investor such as their investing thesis, average investment size, types of deals they invest in, and more.


Operators on Mainshares can leverage our exclusive investor directory to invite prospective investors, including many of those on this year’s list, to their deals.
