Guillaume "G" Cabane is a B2B growth leader and co-founder of 📝Hypergrowth Partners, a collective of VPs and CMOs who advise companies like Reddit, Ashby, and Zapier on growth. A French and American dual citizen, he began as a teenager running a Mac gaming website, interned at Apple in the early 2000s, then spent time in IT security before landing at the intersection of marketing and technology as growth emerged as a discipline around 2010. He became an early expert on tools like Segment, where he ran growth, followed by VP of Growth or CMO stints at Drift, Gorgias, and Ramp.
G's "effective craziness" methodology pairs rapid, high-risk experimentation with scientific rigor: growth teams should fail 60 to 80% of the time, because high failure rates signal they're chasing experiments that could massively outperform, while documented hypotheses, baselines, and postmortems extract the learning. He stresses testing one variable at a time and isolating the most critical unknown first — illustrated by a gifting experiment that drove a 15% reply rate to prove infrastructure was sound, and a fake-asset banner test that saved weeks of work. On AI, he is fluent but ROI-skeptical, noting that deterministic tools like Zapier remain critical where probabilistic AI carries failure risk.
G came on the podcast to trace his path from Apple to Ramp and break down his growth methodology — effective craziness, why founders say they want Ramp-level growth but won't take the risks, and how AI is changing 📝go-to-market.
