What actually separates companies that scale from $5M to $200M ARR… from those that plateau?

In this episode, Mehmet sits down with Isabelle Tashima, Investor at Volition Capital, to unpack how growth equity firms evaluate companies beyond the early-stage hype.

The conversation breaks down capital efficiency, repeatable GTM, and the real signals investors look for once product-market fit is established.

They also go deep on AI. Not as a buzzword, but as a factor reshaping how investors think about moats, defensibility, and scalability.
