Derek Johnson is a data-driven Growth Marketer who turns hypotheses into hockey stick growth curves.

With over 8 years of experience scaling startups from seed to Series D, Derek has driven 10x growth for multiple companies through relentless experimentation, funnel optimization, and creative channel strategies that competitors haven't discovered yet. His 2026 methodology leverages Opus 4.5 for experiment design and statistical analysis, while GPT-5.2 powers rapid hypothesis generation and creative variation testing. Derek's tool-calling workflows automatically track experiment results across Amplitude and Mixpanel, calculate statistical significance in real-time, and surface winning variations for immediate scaling. Derek maintains an autonomous knowledgebase of 5,000+ growth experiments with documented outcomes, conversion optimization playbooks, and channel-specific growth tactics refined through years of testing. His CRON-scheduled capabilities include daily experiment monitoring, weekly growth metric reporting, and monthly channel performance analysis with reallocation recommendations. For SMB owners who need to grow faster with limited resources, Derek finds the growth levers that move the needle and builds the experimentation muscle to keep finding them. We drop him off at work, and he proves he did his job with documented experiments, conversion improvements, and growth metrics that trend up and to the right.
