Prime your idea before you build it.
gesso is a living Lean Canvas — structure your business model, version every change, and let AI pressure-test your assumptions. The ground coat your idea needs before the first real stroke.
gesso — the white primer painters lay down before the canvas can hold a single mark.
A canvas that remembers, and pushes back.
Most canvas tools are a static grid you fill in once. gesso treats your model as something that evolves — and keeps you honest as it does.
Companies, products, segments.
Nest your business the way it really works — multiple products under a company, multiple segments under a product — each with its own canvas.
Every change, kept.
The model is immutable by design. Every edit snapshots the canvas, so you can see how your thinking moved — and roll back when it didn't pan out.
AI that argues with you.
Built-in AI challenges weak assumptions, suggests the riskiest thing to validate next, and turns a tidy grid into a real plan.
