ANECDOTE

Some Products Need Years To Break Out

Mark and panel discuss founders who let projects sit and later saw breakout growth years after initial work (e.g., Replit, Figma).
These examples show product timelines can be multi-year and require patience rather than immediate pivoting.

INSIGHT

AI Cohort Likely To See Massive Failures

Mark Roberge predicts the recent two-year cohort of AI-native startups will see the highest company-level failure rate in tech history.
He allows that a few massive exits could still make the cohort look successful for investors.

ADVICE

Validate Readiness Before Rapid Scaling

Assess readiness before you scale revenue and don't time hiring to VC checks.
Avoid hiring reps fast based on Excel models without validating product-market and go-to-market fit.

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
