Is there any PE equity fund to invest in Zerodha?

Since kamat sir opened up about not going to IPO route for funding , Is there any way I can invest in zerodha may be something like PE fund or may be if any current/ ex-employees want to sell their ESOPs ?

If not zerodha directly , atleast their platforms like coin / PI / sensibull / streak . I am very much interested any hint would be much appreciated .
