Institutional Fund Incubator/Accelerator/Etc.

Greetings all. The long-term plan for my firm is to raise an institutional fund of let's say $100M. I have seen numerous search fund incubators or accelerators but was wondering what options there are for institutional funds. I am aware of Fund Launch Secrets/Black Card but that is the only one. Anyone out there know of any others? Alternatively, would be happy to connect with others whose firms are at a similar stage. Thanks all!
