Claim
The growth playbooks that built LinkedIn, Google, and Heineken into giants were written when markets were less saturated, customers were excited about innovation, and budgets were bigger. Those playbooks don't translate to bootstrapped startups, clever leaders in tech, or independent innovators today. The modern GTM strategist works backward from product-market fit through 135 mental models and 17 workshop templates that force decisions on who you're selling to, what price to set, what channels to focus on, and what growth techniques will actually move the needle.
Mechanism
Old playbooks assume scale-driven distribution (you can buy demand). Modern markets require focus-driven distribution (you have to choose). Mental models force the founder to make explicit choices instead of running a generic checklist; workshop templates compress the decision cycle. The result is a strategy that fits the company's actual constraints rather than imitating Google's.
Conditions
Holds for founders and PMMs at pre-PMF and early-PMF stages. Less critical for mature SaaS where the playbook is already differentiated.
