The Pie Slicer

The online Pie Slicer application captures the contributions made by each team member and calculates each person's share in real-time.

The Pie Slicer follows the Slicing Pie formula

Slicing Pie is a universal formula for creating a perfectly fair equity split in an early-stage, bootstrapped startup. Traditional, old-fashioned equity splits are based on guesses about the future, negotiation skills and rules-of-thumb. The Slicing Pie model is different because it's based on what participants actually contribute over time.

The Pie Slicer applies the Slicing Pie formula as outlined in the book Slicing Pie and The Slicing Pie Handbook.

Keep track of what people actually contribute.

The Slicing Pie Pie Slicer application will help you and your team keep track of your individual contributions and calculate the pie based on the calculations in Slicing Pie. Keep track of time, expenses, supplies, equipment, royalties on ideas, commissions on sales and any other contribution an individual could make.

Contributions can be set to repeat at regular intervals. Set a monthly rent contribution or a weekly payroll, for instance.

Manage access and monitor contributions.

Team members can submit their own contributions through their own account. Pie administrators can manage what individual users can see or do in the Pie Slicer. For instance, the Employee setting allows the user to see only their own contributions while the Executive setting allows the user to see all contributions.

Pie administrators can allow someone to enter contributions directly or require approval before slices are added.

Track direct cash investments with the Well.

The Well feature allows the team to track cash investments in the company. When money is invested it is held in the Well. When money is drawn from the Well to cover company expenses, the Pie Slicer allocates slices to each participant in the Well according to their share. 

The Well helps prevent unnecessary equity allocations by only calculating slices when investment funds are consumed.

Customize variables based on your company's policies.

The Pie Slicer's default settings are set to reflect best practices for fairness as outlined in the Slicing Pie books. However, variables can be changed to reflect your industry norms or company policy.

For example, Pie administrators can edit commission and royalty rates, set up their own project categories or determine how to calculate mileage rates.

Make due diligence a snap.

The Pie Slicer includes logs, reports and charts based on the team's contributions providing valuable insight for managers and potential investors. 

Gain a deeper understanding of how your team is spending their time, investing their cash, and consuming other inputs such as supplies or equipment.

Handle departures fairly while protecting the interests of the company.

When someone leaves the company, the Pie Slicer will help calculate the fair buyout price and re-allocate slices depending on the circumstances of the separation.

Slicing Pie protects the interests of both the company and the individual employees. Being fair to ex-employees is as important as being fair with employees.

Your cap table is always fair!

With Slicing Pie, your cap table always shows the fairest split no matter what changes. All other models and online tools create one-off, fixed equity splits based on estimates and guesses.

Slicing Pie is the only equity model that guarantees a perfectly fair split.

Slicing Pie works. It creates a fair equity split, it prevents equity disputes, and it sets your team up for success. Since publishing the first description of the model in 2010, it has been used by startups all over the world. The books have been translated into many languages and thousands of companies have used this software. In all that time, we have never heard of a single company that failed because they used Slicing Pie. That's a pretty good track record considering that we've seen estimates that as many as 67% of companies who fail do so because of founder disputes.

If your team implements Slicing Pie as described in the books and software and it does not deliver on it's promise of fairness, we will happily refund your money and apologize for wasting your time.

    Hi Mike
    any chance to have the book lead or so that you refer to please.

    Hi Mike

    How do I manage/run multiple pies? I see your plans only include one pie. Suppose I would need to sign up with different email and create a separate account for each pie required?
