For engineering leaders scaling product judgment

Anyone can clone the framework. Getting your team to run on it is the hard part.

Running /pureinn costs nothing. Getting ten engineers who've shipped on instinct for years to trust a spec before they trust their gut - that's the part that doesn't come in a git clone.

How I work

Four things that don't depend on the tool.

Pureinn packages a product methodology that existed before it - discovery, domain modeling, prioritization, delivery discipline - refined across 10+ years of building real products by hand.

It's grounded in 450+ practitioner-sourced observations across JTBD, KANO, Design Thinking, and Hypothesis Validation, not improvised. These four hold regardless of what's running them; the fourth is what changed - how fast they execute now.

Work with me, and your team stops shipping the wrong thing - because the thinking gets fixed before the code does.

01

Discovery that turns a raw signal into a defensible case

Fast, structured, the same quality every time. Clear inputs, clear outputs - no guessing what you'll get out the other end. What comes out isn't a research deck. It's an answer to why this need is real, why the market is moving toward it now, and why the traction you already have will hold up under scrutiny.

02

Domain rigor before a single line of code

Entities, states, business rules - defined and named before the build starts, not reverse-engineered from whatever the code happened to do under a deadline. This is the discipline that keeps “we'll document it later” from becoming “nobody remembers why this works this way.”

03

Decisions built on evidence, not opinion

A prototype in front of five users beats a week of debate in a Slack thread. Every feature gets scored - value against effort, must-have against nice-to-have - so the roadmap reflects what the evidence says, not who argued loudest in the meeting.

04
How execution changed

AI-accelerated execution - from spec to shipped code

Several workstreams run in parallel and converge into one clear output - what used to take weeks now takes days. The multiplier isn't one tool: it's the product methodology above, wired into connected research tools and coding agents that actually ship the code, not just the spec.

Why this exists

The framework is open source. The cultural shift is the work we do together.

Pureinn puts 51product skills in your team's hands. My job is wiring them into the process you actually run - not replacing your team's judgment, sharpening it. Turning people who write code into people who build products is a conversation, not a checkout page.

Describe the process. I'll tell you if it's worth fixing.
