What does LEANSpark do?

LEANSpark is an AI assistant designed specifically for early-stage founders. It helps you systematically test and validate a business idea, following the Lean Canvas methodology. Instead of giving generic advice, it asks about your specific business model, helps you identify the riskiest assumptions, and guides you through designing and running real-world experiments. The goal is to move from guessing to knowing what to build, what to skip, and when to change direction, all within a 90-day framework.

It works by first helping you create or import a Lean Canvas, which is a one-page business model. LEANSpark then scores your model across seven dimensions like Desirability, Feasibility, and Viability, highlighting weak spots. Its core feature is a structured, guided cycle where you Plan an experiment, Do it, Check the results, and Act on the findings (the PDCA cycle). The AI remembers your context throughout, recommends specific frameworks for your current stage, and helps with practical tasks like writing customer interview questions and analyzing the transcripts.

This tool is for anyone with a rough business idea who feels stuck on the next step. It's useful for solo founders, small startup teams, or creators across SaaS, physical products, or services. Real use cases include stress-testing a business plan before writing code, turning a landing page into a structured Lean Canvas, and getting actionable insights from customer interviews instead of vague feedback.
