A method for identifying high-leverage product improvements by focusing on the user 'on the cusp' of conversion or the 'worst-case scenario' user. Solving for the user with the most friction (e.g., bad device, slow network, language barriers) often resolves hidden issues for the entire user base.

"If you don't have a product that's providing real fundamental value to people... you can growth hack your way into something that might last for a few months but people will catch on."

A philosophy that treats algorithms as tools to amplify human intent rather than autonomous decision-makers. It emphasizes that while machines excel at optimization and scale, humans must provide the constraints, strategy, and judgment for unforeseen contexts.

"The algorithms need people to help make judgment calls... Your job is figuring out what the algorithm should be responsible for, what people are responsible for, and the framework for making decisions."

A resource allocation framework for product development. 'Lead Bullets' are small, incremental optimizations (experiments) that accumulate value. 'Cannonballs' are massive, fundamental changes requiring high effort but offering transformational impact.

"There's a laziness that can creep in where you're just finding a lot of little things because they're easier to come up with... Just bang the big things out."
