Dynamic equity is optional
Three ways to run your cap table
Use Aportia as a fully static cap table, a hybrid, or 100% dynamic. You choose the model — and you can switch whenever you want.
Static
Conventional cap table
A classic cap table with fixed percentages or fixed shares — exactly like the tools you already know. No contributions, no recalculations.
- Fixed % or share counts
- No dynamic tracking required
- Ideal when the split is already agreed
Hybrid
The best of both worlds
Lock protected percentages for founders or investors, and let the rest of the pie distribute dynamically from real contributions.
- Fixed + dynamic + reserved
- Protect key stakeholders
- Reward ongoing contribution
Dynamic
100% performance-based
The whole pie splits automatically based on what each person actually contributes — time, cash, IP and resources. Recalculates in real time.
- Everything distributed by contribution
- Real-time recalculation
- Perfect for early-stage teams
Same platform. Same 100% ownership. You decide how it’s split.
No expertise required

It calls things what your country calls them
A Spanish S.L. has participaciones held by socios; a Delaware C-Corp has shares held by shareholders; a US LLC has units held by members. Aportia uses each one where it belongs — in the app, in the reports and in the documents.
And everywhere else?
It works the same. Outside these 11 countries Aportia uses generic wording — shares and shareholders — and every calculation, document and report behaves exactly as it does here.
Equal splits feel fair.
Until they don’t.
Most founding teams lock in equity during their first month — usually splitting it equally. Six months later, when one founder is working 80-hour weeks, another has invested €20K of personal savings, and a third has quietly disengaged, that “fair” deal becomes the root of every conflict.
