GTM: Why Most Go-To-Market Motions Collapse at Scale, with Jeanne DeWitt Grosser, COO at Vercel

Why do so many go-to-market motions fall apart right when a company starts to scale?

In this episode of GTMnow, Sophie Buonassisi sits down with Jeanne DeWitt Grosser, former GTM leader at Google and Stripe and now COO at Vercel, to unpack why GTM fragility is one of the most underdiagnosed risks in startups and scaling companies.

This is a deep, operator-level conversation about what actually breaks in sales, why AI won’t magically fix it, and how the best teams treat go-to-market like a product that must be designed, tested, and iterated.

If you are a founder, operator, or investor navigating growth, this episode will give you clearer mental models for building GTM that actually holds up under pressure.

In this episode, we cover:

• Why most GTM motions fail at scale, even with strong products
• What it really means to treat go-to-market like a product
• How AI changes execution without changing fundamentals
• The rise of the forward deployed engineer
• Why “lost on price” is usually a lie
• What great sales reps still do better than anyone in the AI era
• How to think about joining companies “early” without getting timing wrong

Listen if GTM feels fragile, unpredictable, or overly dependent on heroes.
