The Business Model Canvas consists of nine building blocks: customer segments, value proposition, channels, customer relationships, revenue streams, key resources, key activities, key partnerships, and cost structure. Alexander Osterwalder and Yves Pigneur described it in 2010 in ‘Business Model Generation’ as follows: the Canvas brings all relevant questions about a business model onto a single page. Who really pays? Why do they buy here and not elsewhere? How is value produced and what does it cost?
Everything is interconnected
What appears at first glance to be a checklist follows an internal logic. The right side is customer-centric. It examines what value you create for whom, how you convey it, and how you market it. The left side describes the operational infrastructure—how and with whom the value is produced. In the middle is the value proposition. This is the core that everything else must feed into.
All nine fields are interconnected. If you change the value proposition, you must check whether the channels still fit, whether the customer relationship needs to be reconsidered, and whether the cost structure changes.
The value proposition first
Many founders start with channels or resources. But the right starting point is the center of the Canvas with the value proposition. To articulate this clearly, two questions must be answered: What problem do I solve? And why should someone pay me for this instead of going elsewhere?
A common mistake is confusing value proposition with feature list. “Our app is fast, intuitive, and free” is not a value proposition. “Founders in early phases have no time for accounting. We reduce the time commitment to ten minutes per week” is one. The difference is that the latter identifies the problem, the target audience, and the measurable benefit.
Right side: who buys, who uses, who pays?
The Canvas doesn’t automatically distinguish between users and paying customers. For digital business models especially, this is a critical point. If you’re building a platform where different groups interact, you must think of both as separate customer segments. Each segment has its own value proposition, its own channels, its own relationship needs.
Osterwalder himself recommends filling out the Canvas multiple times: once for each relevant customer segment. That’s a lot of work. But it prevents you from building a business model that doesn’t really work for anyone. The Munich Chamber of Commerce uses the Canvas as a standard starting point in their startup consulting precisely because it forces founders to think concretely about their target audiences early on.
Left side: what do you really need?
The left side of the Canvas answers a question many founders ask too late: What do I really need to deliver my value proposition? Key resources, key activities, and key partnerships determine together with the cost structure whether a business model is viable.
Often the left side is filled out too optimistically. Resources are underestimated, partnerships assumed as given, costs set too low. A rule of thumb circulating in the founder community helps with calibration: plan for double the costs, expect only half of the anticipated revenue.
The most common mistakes
Fill out the Canvas once and never look at it again. It’s a living document. When you open a new channel, change the product, or acquire your first customer, you must update it.
Write the value proposition from the founder’s perspective. What founders think is value doesn’t matter to anyone. What customers perceive as value does.
Treat assumptions as facts. Each field is initially a hypothesis. Only when customers actually buy and a channel actually works do hypotheses become facts.
Ignore the competition. The Canvas reflects the internal business model, not the environment. This is intentional and at the same time not a free pass. If you don’t separately analyze competitors, regulation, or market changes, you have blind spots.
BMC versus Lean Canvas
For those who want to dive deeper, the Lean Canvas model is worth exploring. In 2010, Ash Maurya published the Lean Canvas as a further development specifically for the early startup phase. He replaced four fields with problem, solution, key metrics, and unfair advantage. His reasoning was that when you’re just starting out, you don’t yet know if your business model works. The Lean Canvas focuses on the hypotheses that must be tested first.
In practice, many founders use both. First the Lean Canvas for testing, then BMC for communicating and scaling.
The Canvas convinces before the pitch
According to the ‘German Startup Monitor 2025,’ around three-quarters of surveyed startups plan to raise external capital within the next twelve months. For venture capitalists and business angels, the Canvas is often the first structured insight into a business model—more compact than a business plan, more substantial than a pitch deck.
What interests investors is not the filled-out document, but what’s behind it: Does the founding team understand how the building blocks fit together? Why do customers buy here and not elsewhere?
This also brings us full circle to the pivot. If you update the Canvas regularly from the start, when you change direction you immediately see which hypothesis didn’t hold up—instead of having to laboriously reconstruct it later.
