Build smart.
Not blind.
A method for founders, product, and innovation teams to reduce risk, think clearly, and build tech products that actually work.
Why most startups fail?
Most teams either rush to build or get stuck overthinking. Rarely do they nail both: Building the right thing and building it right.
The Rational Quadrant
Right Problem. Right Product.
Deciding what to build is just as important as how you build it.
Engage customers early , Follow evidence, execute fast, and iterate frequently.
Build in vacuum, focus on tech, struggle to adapt, and fail to gain traction.
Never engage customers and fail to ship the product.
Engage customers to identify opportunities but struggle to execute fast, and fail to deliver value.
