About Funnel Physics

Funnel Physics covers product-led growth: activation, onboarding, packaging and the positioning work that decides whether a self-serve product converts its own users.

Funnel Physics studies product-led growth: where new users activate and where they stall, what packaging and pricing tiers really signal, and how to instrument either without fooling yourself. Every study shows its arithmetic.

Written for Growth product managers and product marketers at self-serve and hybrid companies.
