The history of dynamic equity

For decades, startup founders split equity the same way: sit down on day one, guess who will contribute what, and lock in percentages that never change. The problem? Those guesses are almost always wrong. One founder works 80-hour weeks while another drifts away. The equity split stays frozen.

In 2012, Mike Moyer published Slicing Pie, introducing the concept of dynamic equity—ownership that adjusts based on actual contributions over time. Instead of guessing upfront, you track what everyone puts in (time, money, resources) and calculate fair shares continuously. It was a breakthrough idea that changed how thousands of founders think about equity.

The Slicing Pie book is still worth reading. The core formula is sound, and if you're choosing between a static 50/50 split and any dynamic model, the dynamic model wins every time.

We built Equity Matrix because the idea deserved better software. Modern interface, tax-ready snapshots, loyalty protections, mobile access—features that make dynamic equity practical for teams who don't want to manage spreadsheets. Same fair philosophy, better execution.

Common Questions

Is Equity Matrix based on Slicing Pie?
Both tools use contribution-based equity calculations, but Equity Matrix is its own platform with unique features like tax snapshots, loyalty protections, and multi-company support that Slicing Pie doesn't offer.
Can I migrate from Slicing Pie to Equity Matrix?
We can import existing contributions you have in a CSV or spreadsheet. Contact us and we'll help you get set up.
What are loyalty protections?
Cliffs and thresholds that protect your company from early departures. Set a minimum contribution period before equity vests, or require certain milestones. Slicing Pie awards equity immediately for every contribution—which can be risky.
Will investors accept dynamic equity?
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. We help with that transition.
How does pricing compare?
Equity Matrix starts at $9/month for up to 3 contributors (Early plan) and $49/month for up to 10 contributors (Growth plan). Slicing Pie's pricing is similar, starting around $10/month. Both offer free trials.
What is dynamic equity and how does it work?
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.
Is dynamic equity legally binding?
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.
What happens when a co-founder leaves?
With Slicing Pie, a departing co-founder typically keeps equity based on what they contributed—or loses some depending on departure terms. 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.
Can I use dynamic equity for an LLC?
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.
How do you value time contributions vs cash?
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 Slicing Pie and Equity Matrix use these principles, though the exact multipliers can be customized.
Do I still need a cap table if I use dynamic equity?
Dynamic equity is typically used before you have a formal cap table—during the bootstrapping phase when contributions are still being made. Once you raise funding or reach a natural stopping point, you "freeze" the dynamic equity into fixed percentages and transition to a traditional cap table.
