Have the conversation nobody has.
Most founding teams split equity with a handshake and a spreadsheet, then discover what they actually agreed two years later. Pie Divide turns it into a structured negotiation everyone signs off on — and leaves you a record you can point at.
A full trial run on our standard weights. No card required.

The hard part was never the arithmetic
Teams get the sums right and the conversation wrong. The split gets avoided, settled quickly to keep the peace, and never revisited — and the number one person quietly resents is the one still on the cap table years later.
founding teams divide their equity equally, across 1,476 founders in 511 ventures.
the value the same study estimates is at stake in that one decision: around 10% of the firm, or a quarter of the average founder’s stake.
followed for six months: whether the split was felt to be just— not how large anyone’s share was — predicted whether the team spiralled upward or downward.

Four steps, and nobody can skip one
Every stage needs everyone. That is the point — the structure is what makes the outcome hold.
Agree what matters
Negotiate the weight of each contribution — idea, capital, execution, sales — before anyone sees a number attached to their name. Propose a change, say why, and nothing moves until a co-founder accepts it.

Assess each other
Everyone scores themselves and every co-founder, privately, on the dimensions you agreed. Nobody sees anyone else’s answers while they work — and a 1 means “contributed nothing here”, not a polite low mark.

See the split
One result, computed from everything submitted, with the contribution of each category shown openly rather than as a black box. You can see which categories produced whose share.

Approve it together
It is not final until every founder approves. Anyone can dispute and reopen the round — with the previous result kept intact, so a reopened question starts from what you had rather than from nothing.

That is the whole process
Run all four phases with your real co-founders, free, on our standard weights.
A calculator gives you a number. This gives you an agreement.
The difference shows up on the day someone disagrees with what was decided.
A free equity calculator
- One person, one browser tab
- You rate yourself, with nothing to counterweight it
- Nothing is saved when you close the tab
- No record of who agreed, or when
- Reopening the question starts from zero
Pie Divide
- Every founder takes part, from their own account
- Peer assessment counts for more than self-assessment
- Weights are negotiated and approved before scoring begins
- Unanimous approval, with a timestamped record of it
- Dispute and re-run a round, with the previous result kept beside the new one
Questions founding teams ask
Plain answers, including what this is not. More on the limits is on About, and the two prices are on Pricing.
How is this different from a handshake and a spreadsheet?
Most founding teams split equity with a handshake and a spreadsheet, then discover what they actually agreed two years later. A calculator gives one person a number in one browser tab. Pie Divide runs a structured negotiation: every founder takes part from their own account, peer assessment counts for more than self-assessment, weights are agreed before scoring, and the split is final only when every founder approves. You keep a timestamped record of who agreed and when.
Is what we agree here legally binding?
Pie Divide is not a law firm and does not give legal advice. What the app produces is a record: the weights the team agreed, who proposed what and why, and every approval timestamped against the exact version of the numbers that was on screen at the time. What it does not do is draft, sign or file anything. It is not a founder agreement and it does not issue shares. Turning the split into shares and a signed agreement is a separate step with a lawyer.
What is free, and what is $49.99?
The free version is a full run: every phase, with your real co-founders, on our standard weights. No card required. $49.99 is a one-time charge per project for custom weights, your own categories and items, and the industry templates. There is no subscription and no percentage of anything.
What is Pie Divide not?
Pie Divide is the process of record for founder equity, not a calculator and not a law firm. It does not give legal, tax or financial advice, incorporate a company, file anything, draft or store a founder agreement, issue shares, or model vesting. Those sit with counsel after the split is recorded.
Built so it can’t be gamed
Three decisions that make the result something a team can actually live with.
Your own score counts for less
Rating yourself a ten cannot outvote what your co-founders think.
Change a weight, lose the approvals
Nobody is ever recorded as agreeing to numbers they did not see.
The result is fixed once computed
A finalized split is stored, not recalculated from whatever the weights say later.
The paperwork does not do itself
Finalizing puts a dated checklist in front of the team: incorporate, EIN, bank account, the 83(b) window, founder agreements. What every new company has to do is already on it. What only applies to some is offered separately, so the list you open is short enough to read. Everything on it is yours to re-date, rename or delete.
Dates are a starting point, not advice about your situation. Deadlines vary by entity and state.

Not just venture-backed startups
Anyone going into business with someone else has to divide it. Most of them have never been offered a tool for it.
Startups
Pre-incorporation teams deciding the split before the lawyer papers it.
Agencies & studios
Partners whose contributions look nothing alike and never have.
Trades & construction
One partner brings the capital, another the crew and the customers.
Professional practices
Clinics, firms and consultancies splitting ownership among partners.
Now — not in year three.
