The Science of Scaling: Using data to scale your startup perfectly w/ Mark Roberge

The Science of Scaling: Using data to scale your startup perfectly w/ Mark Roberge

Author: Yaniv Bernstein and Chris Saad May 18, 2026 Duration: 1:05:03

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. 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'.

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 you can act on in week one.


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

  • Hear Mark coach Yaniv through Vera's LIR in real time, and pick up a repeatable method for designing one for your own business

  • 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
