We receive an idea for a service, an application project, or a consulting offer to structure. The classic reflex: open a blank document and write a thirty-page business plan. The problem is that after two weeks, the document is already outdated because the initial assumptions have not been tested against reality.
The canvas offers a radically different approach: to lay out all the components of a project on a single page, and then evolve them as feedback comes in.

Structural Limits of the Canvas in the Face of Regulated or Platform Projects
Before detailing how to fill out a canvas, it is important to know where the tool falls short. The Business Model Canvas is designed around the organization itself: its resources, its partners, its channels. It does not capture what is happening around it.
Specifically, if we launch a connected health product, the canvas does not provide any space for regulatory constraints (CE certification, GDPR health, HDS approval). We can slip them into “key activities” or “key partners,” but that’s just patchwork. The model wasn’t designed for that.

The same observation applies to platform businesses. Network effects, dependence on Apple or Google app stores, commissions taken by a third-party marketplace: none of this naturally fits into the nine blocks. Recent studies highlight that the canvas remains structurally focused on the internal and must be complemented by an analysis of the external environment.
We found it useful, in this case, to add an annex listing three elements: regulatory constraints, dependencies on third-party platforms, and expected network effects. It’s not elegant, but it prevents discovering these blockages during the development phase. To delve deeper into the definition of the canvas on Cyber Business, you can find a clear framing of the blocks and their interconnections.
Canvas as a Hypothesis Map: Filling and Iteration
The most common mistake we observe among project leaders: filling out the canvas once, printing it, and never touching it again. The document ends up in a drawer or as an attachment in a funding file.
A canvas filled out only once and archived has almost no value. What matters is to treat it as a living map of hypotheses to be tested.
Order of Filling in the Field
We always start with the value proposition and customer segments. These two blocks are interdependent: value only exists if someone is willing to pay for it. The other blocks (channels, key resources, cost structure) come next, as they stem from the answers obtained on the first two.
Here’s an order that works in practice:
- Value proposition and customer segments first, tested through interviews or pre-sales before touching on the rest.
- Customer relationships and distribution channels second, to verify how we actually reach the identified target.
- Key resources, partners, and cost structure last, once the value/customer pair is validated by real feedback.
Each block contains hypotheses, not certainties. “Our customers are freelance designers” remains a hypothesis until we have had conversations with freelance designers who confirm the need.
Frequency of Updates
After each significant test (customer interview, acquisition campaign, price test), we revisit the canvas and modify what has changed. A canvas revised five or six times in three months tells the real story of the project. A frozen canvas tells a fiction.
Canvas and Financial Model: Two Distinct Tools Not to Be Confused
We regularly see project leaders trying to integrate a financial forecast into the “revenue streams” and “cost structure” blocks of the canvas. The result is unreadable: numbers piled up on sticky notes, without the rigor of a spreadsheet.
The good practice, increasingly documented, is to clearly separate the canvas from the detailed financial model. The canvas is used to design and communicate the logic of the business model. The financial spreadsheet is used to quantify, project, and simulate.
In the “revenue streams” block of the canvas, we note the type of revenue (subscription, commission, unit sale), not the projected amount. In “cost structure,” we identify the main items (hosting, customer acquisition, production), without going into monthly detail.
This separation has a concrete advantage: when presenting the project to a partner or investor, the canvas provides an overview in two minutes. The financial model then answers profitability questions. Mixing the two produces a document that fulfills neither role correctly.
Lean Canvas or Business Model Canvas: Choose According to the Stage of the Project
The Business Model Canvas by Alexander Osterwalder and the Lean Canvas by Ash Maurya share the same structure of nine blocks, but three boxes differ. The Lean Canvas replaces “key partners” with “problem,” “key activities” with “solution,” and “key resources” with “key metrics.”
In practice, the choice depends on the stage of the project:
- In the exploration phase (still looking for the problem to solve), the Lean Canvas forces you to explicitly formulate the problem and existing alternatives. This is more useful than a list of partners that haven’t been contacted yet.
- In the structuring phase (the product exists, we are building the organization), the Business Model Canvas regains the advantage because partners, resources, and activities become concrete operational subjects.
- For a platform or marketplace project, neither is sufficient alone. We complement with an analysis of network effects and technical dependencies, as mentioned earlier.
The canvas is not a form to fill out to obtain funding. It is a working tool that loses its value as soon as it stops evolving. Regardless of the format chosen, the discipline that matters is that of updating: confronting each box with feedback from the field, modifying what no longer holds, and accepting that the final version does not exist.
