Exit Opps from TMT Boutique

I know firms like Raine, LionTree, Allen & Co, Union Square Advisors, Financial Technology Partners, etc don't have a lot of precedence for exit opps, but do they still get looks from recruiters for PE? In general, how are the exit opps coming from each of these shops?

Interested in starting off at one of the above firms for two years and moving to PE.
