The end of the zero-interest-rate period compressed lending margins, but it had a silver lining. It forced fintech companies to become 'full-stack' by acquiring bank charters and building significant revenue streams from customer deposits, ultimately making their business models more durable.

During Ethic's long build phase before traction, the founder found it crucial to ignore external validation signals like other companies' funding announcements. The key to surviving this lonely period is a relentless daily focus on execution and solving customer problems, not chasing industry hype.

The founder describes growth not as a smooth upward curve, but as a series of chaotic 'bursts.' Each spurt breaks existing systems and requires intense effort to adapt processes and thinking to meet the new demand. The feeling of success only arrives after the chaos has been managed and new systems are in place.

Emilie Choi explains that market downturns are beneficial because they drive out short-term "mercenaries," allowing dedicated builders to thrive. Her promotion came from proving she could operate effectively during a downturn, rewarding her resilience when others fled.

Early in a technology cycle like the web or AI, successful founders must be technical geniuses to build necessary infrastructure. As the ecosystem matures with tools like AWS or open-source models, the advantage shifts to product geniuses who can build great user experiences without deep technical expertise.

Maximum growth occurs during 'boring' periods of repetitive execution, not exciting periods of innovation. Many leaders, craving novelty, mistake this valuable stability for stagnation and prematurely introduce disruptive changes that hurt the compounding returns of a team mastering its craft.

Founder Sam Darawish argues that a healthy, moderate growth rate (25-30%) is often better than chasing venture-backed hyper-growth. He believes rapid growth can lead to taking on non-ICP customers, which pulls the product in multiple directions, wastes resources, and ultimately thins the team's focus.

CEO Vlad Tenev considers 2022 the "refounding" of Robinhood. The business model strategically shifted from catering primarily to first-time investors to focusing on more sophisticated, resilient active traders. This pivot drove a 5x increase in product velocity (from one to five major new products per year) and built a more cycle-agnostic business.

The 2022-2023 market downturn acted as a forcing function for survival. Point solutions like neobanks had to expand into lending or investing to retain users. This culling process resulted in the winners emerging as much more comprehensive, full-fledged financial platforms, not just niche apps.
