## What is Outthink?

Think through any problem.

The world's best engineers, founders, and investors don't just work harder — they think differently. They use mental frameworks: structured approaches to decisions that cut through complexity and reveal what matters.

Outthink puts 16 of these frameworks in your pocket.

What's inside:

• Eisenhower Matrix — Prioritize ruthlessly. Separate urgent from important.

• Two-Way Door Decisions (Bezos) — Know when to move fast and when to deliberate.

• Inversion (Munger) — Solve problems by thinking backwards. Avoid failure modes to succeed.

• The 5-Step Algorithm (Musk) — Question, delete, simplify, accelerate, automate. In that order.

• Pareto 80/20 — Find the vital few inputs that drive most results.

• First Principles — Break problems down to fundamental truths and rebuild.

• Pre-mortem — Imagine failure before it happens. Then prevent it.

• And 9 more frameworks from thinkers like Feynman, Boyd, and Buffett.

How it works:

Each framework is interactive. Enter your actual decision, goal, or problem — and work through it step by step. Get actionable insights, not just theory.

Free to start:

4 complete frameworks are free forever. Unlock all 16 (plus future additions) with a one-time Founding Member purchase — no subscriptions.

Built for doers:

Whether you're making a career move, prioritizing a product roadmap, or deciding whether to buy that house — Outthink helps you think it through.

"I think it is possible for ordinary people to choose to be extraordinary." — Elon Musk
