THE NEW REALITY

When code becomes trivial with AI, the quality of ideation and turning ideas into products people want become the only differentiators.

THE PROBLEM

Traditional hackathons waste time on shallow brainstorming, producing technically impressive demos that solve non-existent problems.

Experts with deep domain knowledge lack the product craft to transform insights into solutions people actually use.

THE SOLUTION

EXPERTS (NGOs, researchers, professionals) define thoughtful challenges based on real-world expertise.

PRODUCT BUILDERS transform these visions into usable products in one weekend.

Domain Expertise + Product Craft = Solutions That Matter

THE 5 PRINCIPLES

Our manifesto for the AI era

01

Tech is commodity, product is value

Code is free, user experience is precious

02

Expert problems deserve product solutions

Not just technical demos

03

Great products need both vision AND craft

Ideas alone are not enough

04

Builders aren't coders, they're product creators

Focus on experience, not the stack

05

User impact > technical elegance

What matters is adoption
