Always Fair

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.

    I need to setup a partition and I can not figure out how to do that in the shreadsheet nor in thepieslicer. Please tell me how to add a partition.

    • The spreadsheet and the software won’t help you manage a partition because it just divides up what’s left. You shouldn’t use a partition anyway. I regret putting that in the book and will remove it from future updates… It’s not really fair!

      • ryan

        Thanks for the reply. I’ve been building a business on my owner for the last 7 years and current annual profit is about $150,000. I have reached a point where I am positioned well for significant growth and have started working with two grunts that I would like to share equity with. I thought a partition would be perfect for this situation. I wouldn’t know where to begin with trying to calculate my share of the pie. Also considering my contribution to then company I want to insure that my share is always greater than 50%. My plan was to partition 50% and then share the rest between myself and the other grunts. Wouldn’t the partition be handled the same way as if an investor purchased a specific share of the company? How would that be reflected in the spreadsheet or software?

        • The spreadsheet and software don’t accommodate a partition. You can do a retrofit with this tool:

          The model will always give you what you deserve to have. If you deserve 50% the model will give you 50%. I understand the desire for controlling interest, but giving yourself a fixed split isn’t the best way to do it. Putting up more than 50% if the risk is.

          If you do use a partition for 50% you simply apply the Slicing Pie split to the remaining 50%. You, too, should participate in the Slicing Pie model.

    Is there an API on the roadmap by any chance? 🙂

    • Nothing yet, but I’d love to know what you have in mind!

      • Jason Asbahr

        Offhand, automatic logging from third party time tracker software would be a handy use case needing an API.

        • Which tracker do you use?

    Hi, is there a possible integration with Harvest app? Or alternatively a mobile app where individual members can set their own contributions especially time!
    Our team got used to the ease of time and expense entry on Harvest mobile app, as you recommended in Slicing Pie. Thx

    Btw. Big fan, great book & stellar app!

    • Mobile app…maybe, Harvest integration…probably not. When I wrote Slicing Pie I did not have the Slicing Pie App built yet so I recommended Harvest. I still like Harvest, but there are lots of other time-tracking tools out there and I don’t know how much value-add I could create through integrations at this point. You can use harvest to track time and expenses and then create an invoice that you can enter into the Pie Slicer

    Beware guys, this software has so many bugs. Have been waiting for months for them to send me passwords that work for my team members. They are really slow to respond, if at all, to email queries and there is no telephone number to call. If they get it sorted and improve on customer service then great, but in the meantime I wouldn’t waste your money or time.

    Hi, it would be awesome if you could do API w Harvest (or other hourly tracking tool). We use Harvest + asana Prj Mgmt tool to track hours and tasks completed.

  • John Martin

    If I begin using the free Slicing Pie Excel spreadsheet, can I later import the spreadsheet into the paid subscription online tool?

    • Hi John,

      While there is not an import tool for the spreadsheet you can get started with the Pie Slicer by making initial cash and non-cash entries for each participant. The online tool is easier to use than the spreadsheet.

    Has anyone used the software for company ESOPs?

    • Slicing Pie is for early-stage, bootstrapped startups. ESOPs are generally used in more established companies with an underlying valuation.

  • Mike

    Can the software do what the book refers to as “calibration”? Can it split different grunts or different sectors of the business up where they each have their own “sub-pie” which is then divided in accordance with what each member contributed? Simple stupid example = the engineers don’t get marketing pie unless they contribute to marketing in a meaningful way.

    • Technically, yes, but I don’t recommend taking that approach because it’s not fair. It was a mistake to include that in the book and I did take it out of The Slicing Pie Handbook. The model works when you apply it as described, customization will only make it less fair.

  • Mike

    Am I able to change subscriptions, or do you have to know which one you want on the front end?

    • Unfortunately, it’s not possible to change payment plans…

    Hi, I was about to sign up for the monthly plan (which shows up on this page as being $5/mo, but when I clicked through to the signup page, the price appears as $9.99/mo. Can you please tell me how I get the $5/mo price? Thanks!

    • Hmmm…somehow you reached a page to one of our staging servers! Sorry, this price is long gone. The current price is 9.95 and will be going up again soon. If you sign up your price won’t change. It’s well worth the money!

  • Hi Mike, we like fairness and fairmondo – its one of the underpinning values of our business. We’ve been plodding along for a couple of years in our spare time. We have a high degree of trust. We now need to recruit more Pioneers (our preferred term for Grunts). We started with one cooperative and have now created a second. The first coop has been building and marketing the idea and we would like not to retrospectively capture and freeze the past effort of the founders and “invest” this in the new coop. At the moment its the same member/owners. Any suggestions about the best way to handle this transition? Slicing Pie mentions both freezing and retro accounting. Cheers Bob

    • also – forgot – are there plans for an app for android

      • No, but the tool is responsive and should work well in a mobile browser…!

    • Hi Bob,

      I’m not entirely sure what you are asking…why two companies? You want to do a fixed split with one and Slicing Pie with the other?


  • myRecdex

    My co-founder and I have been working on our startup since January 2017 and have been putting in roughly the same amount of time and expenses into the company – we both agree that we are equal partners today at 50% each. We’re about to bring on a technical partner and we’ve only just stumbled across slicing pie. We think it’s a great tool and concept but we don’t remember all the time and investment spent over the last year to input into the tool to bring the pie up to date so that we can accurately allocate pie slices with the new partner. Is it too late for us to use this tool? Or is there a solution to this?

  • Paul

    Does the software allow you to see slices and other data at a historical point in time (ex. previous year’s end), or just the most current data?

    • It always displays the current split. Nobody has asked for this feature before, how would you use it?

      • Paul

        In meetings where members gets a number of votes corresponding to their proportion of the split, we may base voting on the split as of the last day of the previous month or quarter. Granted we’re still at an early stage and haven’t reached this point yet.

  • Mike McLin

    I know the book had a couple methods where early founders could be rewarded. One of which was increasing the theoretical value proportionally right before bringing on an additional grunt. What are your thoughts on a monthly/quarterly/etc dividend (of value) to grunts. That would be a time-based way to artificially grow the theoretical value, rewarding grunts based on how seasoned they are in the company. It basically adds a time-based ingredient to the pie. Have you heard or thought about something like this, and if so do you have any metrics/values you felt worked well?

    • Hi Mike,

      I no longer recommend increasing the value of the Pie (aka “Calibration”) but I’m not opposed to providing an incentive bonus from time to time as long as it’s logical. Giving someone a monthly bonus for meeting goals and milestones, for instance, would be an option. If you had a person with a $100,000 fair market salary a $2,000 monthly performance-based bonus could work. A $10,000 monthly bonus might be too high.

      Always ask yourself this: IF I were paying cash, how much would be reasonable? If you have the cash, pay it, if not, allocate slices


      PS: A “slice” = $1 theoretical
