You probably want the kind of private equity funds that do succession transactions.

Small slow growing businesses tend not to actually need capital very often, so there isn't exactly a huge market for investing in them.

On the other hand, you get a lot of businesses whose owners are getting old / sick of the business. They need somebody to buy them out and install a new management structure.

There are a bunch of funds who do things like that. Look for "Private Equity" as a more broad category rather than just "Venture Capital".
