> The clinic is the collateral to the bank. VC stand to loose nothing
This is actually a case where using the correct terminology clarifies.
VCs don’t do LBOs. Private equity firms do. When their deals go bust they lose the equity they invested. That equity is the first layer to take a loss. When that happens, the lenders—whether they be banks or private credit firms—take over the company, often converting some of their previous debt into equity.
There is a lot of risk in LBOs. It’s why they have such a mixed record.
PE includes buy-out (leveraged and not) and VC transactions. PE is typically any medium to long term equity investment not traded publicly on an exchange. Even this is cloudy now that the PE firms themselves are going public.
LBOs are also not a black and white classification, at least not the way they were in the Gordon Gecko 80's, with varying levels of target-borne debt financing specific to the deal. So while I agree "VCs don't do LBOs", PE does both LBOs and VC deals, with the PE firms doing their own style of fund and deals.
I found this book (though dated) to be a more academic analysis of PE: https://www.wiley.com/en-us/Private+Equity%3A+History%2C+Gov...
