Validate Your Startup Idea in 30 Days

Learn how to test your idea quickly, cheaply, and effectively. Get users first, then build.


Course Overview

The most common mistake first time founders make is they don't validate their idea properly – or at all. Too often, founders plunge headfirst into working on their ideas without ensuring it's viability. Result? Months or even years of wasted time, money and opportunities working on something nobody wants.

Learn how to get users first (yes, you can do this!), then build your product based on what you know users want. Discover whether your startup idea is one that people want and will use. Find out quickly, at low cost, and with no code.

Learn from Successful Founders

Drawing from their own entrepreneurial journeys – spanning two decades, successful exits, and a $2 billion unicorn – Brian Ma and Hsu Ken Ooi have also amassed invaluable experience engaging with thousands of startups as Managing Partners of Iterative, a YC-style program tailored for Southeast Asia.
