Most founders treat 'scale' like a switch you flip after raising a round: hire 14 reps, 10x the ad spend, and pray. About half scale too early and burn the runway, while the other half scale too late and get caught by a more aggressive competitor. But almost nobody can tell you, in measurable terms, when they're actually ready.

In this episode, Yaniv Bernstein is joined by Mark Roberge, founding CRO at HubSpot (where he scaled the company from $0 to $100M ARR), senior lecturer at Harvard Business School, cofounder of Stage 2 Capital, and author of the new book 'The Science of Scaling: Using Data to Decide When — and How Fast — to Scale Revenue'.

Mark walks Yaniv through his impressive data-driven framework for scaling that he's spent a decade refining, covering how to objectively define product-market fit, why customer retention is the only honest measure of PMF, and how to instrument a Leading Indicator of Retention that you can act on in week one rather than year two.

In this episode, you will:
* Learn why retention is the only honest measure of product-market fit, and why most founders are flying blind without it
* Discover Mark's framework for building a Leading Indicator of Retention (LIR) you can measure in week one, using Slack, HubSpot, and Facebook as worked examples
* Understand the four selection criteria for a great LIR event: it must be objective, instrumentable, correlated with value, and correlated with your unique value prop
* Hear Mark coach Yaniv through Vera's LIR in real time, and pick up a repeatable method for designing one for your own business
* Explore why 'go-to-market fit' must be sequenced after product-market fit, and the risk of optimizing your GTM motion on the wrong product-market combo
* Learn the 'Stay/Go/Slow' model for pacing hires and spend post-raise, and why startups should reassess monthly or quarterly rather than locking in an annual plan
* Get Mark's take on why 'paranoid optimism' is the trait that correlates most strongly with founder success, and the link between that trait and founder mental health
