Product canvas

A product canvas is a short description of what you are selling. Every campaign starts from one, and it is the single source the AI reads before it generates anything else.

That makes it the highest-leverage text in the product. Segments, value propositions, personas and every message trace back to it, so an hour spent here saves an afternoon of rewriting message series that are individually fine and collectively aimed at the wrong problem.

What goes into it

Canvas name. An internal label, for example “Acme invoicing software”. Nobody outside your workspace sees it.

Product or service description. As detailed as you can make it. This is what the AI reads to generate your value propositions, so a vague description produces vague campaigns.

What makes a description work

The instinct is to describe the product. The useful version describes the situation the buyer is in before they have it.

Compare two descriptions of the same product:

Invoicing software with OCR, an approval workflow and accounting integrations.

Mid-sized manufacturers receive several hundred supplier invoices a month on paper and by email. Somebody in finance types them in by hand, chases approvals by email, and closes the month three days late because half the approvals are still missing. We capture the invoice automatically, route it to whoever has to approve it, and post it to the accounting system. Bought by finance managers, usually after an audit or a failed month-end close.

The first produces messages about features. The second gives the AI a problem, a person, a moment and a consequence, and those are what a message needs to earn a reply.

Four things worth including, because they are the ones the generation actually uses:

• the problem, described as it looks from the buyer’s desk rather than as a category;
• who buys it and who else has to agree;
• what triggers the purchase, the event that turns a nuisance into a project;
• what you deliberately do not do, which is what keeps the AI from promising it.

What it is not

It is not a campaign brief. The canvas describes the product and is reused; the brief describes one campaign, its goal and its audience, and lives with that campaign. If you find yourself writing “this quarter” or “for the German market” into the canvas, that belongs in the brief.

It is not marketing copy either. Nothing from the canvas is published verbatim. Write it plainly, as you would explain the product to a new colleague.

How it is used downstream

Everything in a campaign traces back to it:

• Target segments and value propositions are generated from it.
• Message sequences build on those value propositions, so a clearer canvas means less rewriting at the end of the chain, where rewriting is most expensive.

Reusing and changing it

One canvas can serve several campaigns, for example one campaign per target market or per segment, all pointing at the same product description. That is the normal case, and it is what makes the second campaign much faster than the first.

Editing a canvas does not rewrite campaigns already generated from it. Existing segments, personas and message series stay as they are, because they have been reviewed and approved and silently regenerating them would discard that work. To apply a substantially changed canvas, start the affected campaign over, which clears the generated material while keeping the campaign, its brief and the canvas itself.
