List of "Accelerators" and "Search Partners"

Using accelerators and organizations who provide direct assistance to searchers has its pros and cons, but searchers would likely benefit from a one-stop list of accelerators and groups who provide hands-on assistance to searchers working through the search and acquisition process (and possibly operating and exiting also). There are a few scattered posts on searchfunder.com that mention accelerators and reference a well written article by Jake Nicholson on the SMEVentures site, but the information is thin. A few entities that I have found include the fairly well known Search Fund Accelerator, Endurance Search Partners, NextGen Growth Partners, Pacific Lake Partners, and Broadtree Partners. Please comment below to add to this short list. I'm sure there are more out there.
