The Slicing Pie model is excellent. The official software around it — The Pie Slicer from slicingpie.com — is essentially a downloadable spreadsheet plus a low-profile app, which is why many founders end up in paid Notion templates and homemade sheets instead. If you love the model but want a modern tool to run it, Equafy applies Slicing Pie on a real cap table and does the one thing spreadsheets and the Pie Slicer can't: freeze the dynamic split into fixed shares when you raise.

Credit where it's due: Mike Moyer's Slicing Pie (Grunt Fund) is the clearest framework for fair, contribution-based equity in the pre-funding phase. The gap isn't the model — it's the software. The official Pie Slicer is a spreadsheet-plus-basic-app product, so teams outgrow it the moment they need a real cap table, convertibles, or anything an investor will actually look at.
A dynamic-equity tool should do more than divide a pie. It should hold a real cap table, understand the instruments a startup actually issues, and — critically — let you exit the dynamic phase cleanly when you raise. Here's the checklist worth measuring any option against:
The Pie Slicer and a spreadsheet can both compute a dynamic split. Neither gives you a cap table you can raise on, and neither can convert the dynamic model into fixed shares. That's the line Equafy is built to cross.
| Equafy | The Pie Slicer | Spreadsheet | |
|---|---|---|---|
| Live dynamic split | Yes | Yes | Manual formulas |
| Editable multipliers | Yes | Yes | Manual |
| Real cap table | Yes | No | No |
| SAFEs & convertibles | Yes | No | No |
| Freeze dynamic → static | Yes | No | No |
| Round / dilution simulator | Yes | No | No |
| Price | Free to start | $19.95/mo · $199.95/yr | Free / paid templates |
The reason to switch isn't a nicer split screen — it's what happens next. When an investor shows up, Equafy freezes each member's dynamic share into fixed shares in one click, then manages the rest of the journey (share classes, SAFEs, round simulation) on the same cap table. With a spreadsheet or the Pie Slicer, that's where the tool stops and the manual rebuild begins.
The feature the incumbent doesn't have
Freezing a dynamic split into an investor-ready static cap table — in one step, with an audit trail — is exactly what a spreadsheet and The Pie Slicer can't do, and it's the moment that matters most.
Equafy is a modern alternative that runs the Slicing Pie model on a real cap table — with editable multipliers, SAFEs and share classes, a round simulator, and a one-click freeze from dynamic to static when you raise. It's free to start.
For most teams, yes. The Pie Slicer computes a dynamic split; Equafy does that and adds a real cap table, convertibles, round simulation and the freeze to static — the pieces you need once you move past the spreadsheet stage.
Equafy implements the same dynamic, contribution-based logic that Slicing Pie popularized: contributions are valued and multiplied per type into slices, and each member's share is their slices over the team total. You can also mix in fixed equity and a reserved pool.
Equafy is free to start, with no download and no spreadsheet to maintain. The Pie Slicer is priced at $19.95/month or $199.95/year for a spreadsheet-plus-app product without a real cap table.
Equafy runs Slicing Pie on a real cap table and freezes it to fixed shares when you raise — everything the Pie Slicer and a spreadsheet can't do.
