Mark Roberge (Ex-HubSpot CRO): "AI Startups Will See the Highest Failure Rate in History"

Mark Roberge is calling it now: we are about to witness the highest failure rate for a single cohort of startups in the history of tech. As author of Science of Scaling, and co-founder of Stage 2 Capital, Mark joins the pod to dismantle the "growth at all costs" mindset that still plagues founders. He explains why the assembly-line sales model is dead and how AI will force a return to the full-cycle "rainmaker" rep. **Key moments:** The AI Bubble: Why the index fund of the last two years of AI investments is likely doomed. Fixing Your ICP: And how optimizing for CAC or inbound volume without ICP fundamentals in place is a recipe for disaster The 80% Rule: How AI moves reps from 25% selling time to 80%, and what that means for the future of SDR, AE, and CS functions LIR - What it is and Why It Matters: Why every board deck needs a a LIR slide to predict product-market fit before revenue numbers hit **Note:** Mark is donating 100% of the proceeds from his new book to mental health causes.
