HubSpot’s First CRO on Scaling Smarter, Not Faster with Mark Roberge

Most startups obsess over growth. Very few actually understand when scaling makes sense—and when it doesn’t.

In this episode, John talks with Mark Roberge about the real science behind building and scaling a company. They unpack the myths around product-market fit, the ethical decision point every salesperson faces, and why revenue alone can be a dangerously misleading signal for founders.
