Talk

1 hour 15 minutes

One brave startup. One ambitious growth plan. And a panel of VCs who’ve seen it all—and aren’t afraid to say what they think.

In this fun-but-fierce session, a CEO will pitch their scale-up strategy live, only to face a panel of sharp-tongued investors ready to poke holes, ask the uncomfortable questions, and serve up some spicy feedback. But it’s not just about the roast—these VCs will also share real-world advice and help reshape the plan into - hopefully - something fundable.

It’s part pitch, part pressure test, and 100% learning opportunity for anyone serious about scaling smart. Bring popcorn.
