Mark Roberge delivers a keynote at SXSW detailing the data-driven framework behind his book, The Science of Scaling.

Roberge explains that waiting for annual customer retention figures means running a company a year too late, so founders must establish an observable, leading indicator of retention within the customer's first month.
Roberge cautions founders against treating scaling as a single massive hiring blitz after a funding round. Instead, he advocates establishing a steady hiring pace and using quarterly data milestones to decide whether to stay, accelerate, or slow down.
Roberge stresses that startups frequently derail by letting sales representatives close deals outside their core target audience. He argues that a company's true market is defined exclusively by who sales reps are permitted to sell to.
Roberge predicts that artificial intelligence will reverse the decades-long trend of hyper-specialized sales roles like SDRs and CSMs, pushing organizations back toward full-cycle sales reps with much higher manager-to-rep ratios.
