Signal Over Noise book cover showing a minimalist design with bold typography

Publishes May 12, 2026 (pre-order today)

Most decisions aren't blocked by a lack of data—they're blocked by messy data.

What this book does: A field guide to framing choices, triaging uncertainty, and moving forward with guardrails. You'll learn a repeatable cadence for product bets, growth experiments, and operational changes—under constraints that look like the real world.

Who it's for: Product managers, growth leads, analysts, ops leaders, founders, and anyone asked, "So…what's the call?"

Tone: Practical, example-driven, no jargon; models you can teach to your team.

What You'll Learn

Five core frameworks to make better decisions with imperfect data

Decision Frames That Survive the Meeting

A 7-question checklist that turns opinions into options.

Estimating with Ranges

Use order-of-magnitude math and base rates to avoid false precision.

Evidence Triage

Rank inputs by reliability × relevance so loud data doesn't win by default.

Experiment Design That Answers the Real Question

Guardrails, minimal viable tests, and when to not A/B.

Narratives That Align Stakeholders

A memo structure that makes your trade-offs legible and defensible.
