Lean Startup
A methodology for developing products through validated learning and rapid iteration.
Definition
The lean startup methodology, popularized by Eric Ries, emphasizes building a minimum viable product (MVP), measuring customer response, and learning from the data to iterate quickly. The core loop is Build-Measure-Learn. Instead of spending months on a business plan, you test assumptions with real customers as fast as possible.
Why it matters for founders
The lean approach reduces the risk of building something nobody wants. Instead of betting everything on a grand plan, you make small bets, learn fast, and adapt. This is especially critical when you have limited runway.
Example
Instead of building a full platform, a founder creates a landing page describing the product, runs $200 in ads, and measures how many people sign up for the waitlist. In 48 hours, they know if there's demand.
How Foundra helps
Foundra is built on lean principles. Each phase forces you to validate before building. The Next 7 Days Plan card in the Spark phase gives you the smallest set of actions to create momentum.
