Lean-Case Workshops are a much better way than Excel to give investors and startups the numbers and metrics which they want

The Relevance of Unit Economics impacts every startup

Key Question "Is Customer Lifetime Value higher than Cost of Customer Acquisition?" is rarely addressed

One of the most common oversights of a seed stage company (or an innovation project) is not thinking about unit economics at the early stages of their business. Far too frequently we see strong founding teams raise a seed and unfortunately fail to close an A-round because unit economics never came close to working even though they thought they actually were working. These situations are avoidable, and simply require some conversation around the unit economics framework and theory.

... and Lean-Canvas and Design Thinking do not provide any guidance

Methodologies surrender to the complexity of business models and accept Excel dominance


.. but Excel as a solution kills investor’s trust

If startups have to create a business model to show investors, what are their options?


Excel is a solution. But it's really part of the problem. Using Excel always leads to inconsistent results.

This totally kills investor’s trust your business
