Slicing Pie method (Grunt Hourly Rate Rate)

The Slicing Pie method is a dynamic model for splitting equity among co-founders, allocating shares in proportion to each person's actual contribution over time: hours worked, cash contributed, professional relationships leveraged, or decisive ideas.

‍

The calculation relies on the Grunt Hourly Rate Rate (GHRR), defined as the difference between a co-founder's market salary and the salary actually paid, divided by hours worked, then multiplied by a risk factor specific to the contribution made. This formula converts contributions as varied as unpaid time, invested cash, or access to a commercial network into equity shares.

‍

The method's main appeal is deferring the negotiation of a fixed split, often premature and conflict-prone, until co-founders' actual contributions are better known: a 50/50 split decided on day one can prove deeply unfair if one co-founder ends up carrying most of the product development while the other gradually steps back, a scenario Slicing Pie corrects dynamically over time rather than through later renegotiation.

Notably, the canton of Zurich accepted this method as the basis for a tax ruling, giving it practical recognition in Switzerland. For co-founders struggling to agree on a fixed split at incorporation, Slicing Pie offers a dynamic alternative to document as part of founder-capital financial structuring.
