Tools for thinking, deciding and building better products.
A growing collection of frameworks, templates, mental models and practical tools I've developed, adapted or found useful in the real work of product.
Use them. Break them. Make them better.

The layers under a financial product: rails, ledgers, compliance controls, partners and operations.
What has to be true before a regulated financial product is allowed to meet customers.
Using AI to widen discovery and pressure-test your thinking, not to generate confident nonsense.
