SliceFair vs Equity Matrix

SliceFair is a basic web app that implements the Slicing Pie methodology for dynamic equity. It was built as an MVP and offers core contribution tracking at a one-time price.

We can import existing contributions you have in a CSV or spreadsheet. Contact us and we'll help you get set up.

Cliffs and thresholds that protect your company from early departures. Set a minimum contribution period before equity vests, or require certain milestones. Basic Slicing Pie tools award equity immediately—which can be risky if a co-founder leaves after a month.

Both tools use contribution-based equity calculations inspired by dynamic equity principles. Equity Matrix builds on this foundation with additional features like tax snapshots, loyalty protections, and detailed contributor profiles that go beyond the basic Slicing Pie formula.

Dynamic equity is a method where ownership percentages adjust based on actual contributions over time, rather than being fixed upfront. Each person's time, money, and resources are tracked and converted into "slices" that determine their ownership stake. As more contributions are made, the percentages recalculate automatically.

You convert to a fixed cap table when you're ready to raise. Dynamic equity is for the pre-funding stage when contributions are still being made and ownership is uncertain. Once you reach a fundraising milestone, you "freeze" the dynamic percentages into fixed ownership and transition to a traditional cap table that investors expect.

The software tracks contributions and calculates ownership, but you'll need a proper legal agreement (like an Operating Agreement for LLCs) to make it binding. We recommend working with an attorney to formalize your dynamic equity arrangement. Equity Matrix is working on built-in agreement templates to make this easier.

With basic Slicing Pie tools like SliceFair, a departing co-founder typically keeps equity based on what they contributed. Equity Matrix adds loyalty protections (cliffs and thresholds) so you can require minimum commitment periods before equity fully vests, reducing the risk of early departures walking away with significant ownership.

Yes, dynamic equity works well for LLCs. In fact, LLCs have more flexibility than corporations for adjusting ownership. The main challenge is tax reporting—K-1 forms require averaged ownership percentages. Equity Matrix's tax snapshot feature solves this by calculating the exact percentages you need for any reporting period. SliceFair doesn't offer this feature.

Time is typically valued at each person's hourly rate (what they'd earn elsewhere). Cash contributions are often multiplied by a risk factor (commonly 2x-4x) since cash is harder to recover than time if the venture fails. Both SliceFair and Equity Matrix use these principles, though the exact multipliers can be customized.

SliceFair was built as a weekend project and charges a one-time fee—but that means limited ongoing development and support. Equity Matrix's subscription model funds continuous improvements, new features, and responsive support. You're paying for software that grows with your needs, not a static tool that may become outdated.
