Clarno

Simulation tool that helps founders validate what to build before building it

Webfreemiumglobal

Clarno is a simulation tool that walks founders through a structured decision workflow to map their problem space, user struggle, and demand before building, using AI 'User Twins' that simulate how potential users would react. It generates founder-ready assets like opportunity solution trees and validation reports, aimed at reducing wasted build time on the wrong direction, with a free tier and paid plans.
