"There's 20 fires going on at every moment in the office and you have enough water to put out four."

Mark Roberge shares what it takes to build and scale a company, from finding product-market fit to knowing when it's time to grow.

He also shares the framework behind his new book, The Science of Selling, and why founders should scale based on their own data, not another company's success.

Guest: Mark Roberge, Founding CRO of HubSpot, HBS Professor, and Co-Founder at Stage 2 Capital
