After turning off paid marketing, Zipline's growth continued to accelerate. The CEO discovered that the spectacle of a robot delivering items to a home is inherently shareable content, with customers' viral TikTok videos becoming its most effective and free marketing channel.

James Ashford modeled his marketing on celebrity chefs who share recipes freely yet still have packed restaurants. He taught accountants exactly how to improve their pricing without his software, building trust so that when they wanted an easier solution, GoProposal was the only choice.

Instead of traditional marketing, Higgsfield's go-to-market strategy focused on creators who teach others how to use AI tools. By positioning their product as the best tool for specific use cases these creators teach (like product placement), they generated powerful, organic distribution and initial customer acquisition.

Instead of building a consumer brand from scratch, a technologically innovative but unknown company can license its core tech to an established player. This go-to-market strategy leverages the partner's brand equity and distribution to reach customers faster and validate the technology without massive marketing spend.

This strategy removes barriers to entry and drives word-of-mouth more effectively than competing for eyeballs on traditional paid ad channels.

Robinhood amassed nearly a million users before launch without a marketing team. Their key tactic was a gamified waitlist where users could see their position in line and jump ahead by referring friends, creating a powerful and cost-free viral acquisition loop.

Hera's explosive growth came from organic word-of-mouth, with YouTubers making videos voluntarily. The founder's philosophy is that the best marketing is no marketing; a product that solves a real pain point spreads naturally. Paid marketing is seen as a 'tax' for not having achieved strong PMF.

Instead of paid marketing, Nubank scaled to over 120 million users with a customer acquisition cost of just a few dollars. This was achieved organically through word-of-mouth, fueled by a superior value proposition (no fees, better service) that solved a clear and painful consumer problem, enabled by a 20x more efficient cost structure.

Early on, Tock turned down restaurant groups eager to sign up. The founders knew their product lacked features crucial for those clients, and a premature onboarding would lead to failure and churn. By saying "not yet," they protected their reputation and successfully signed those same clients years later.
