Learn how to divide equity with co-founders in a way that feels fair, aligns with contributions, and avoids problems later.
Learning goal
Starting a startup is exciting, until it’s time to talk ownership.
That’s when things get real.
Equity splits often create the biggest tension between co-founders.
Not because people are greedy, but because expectations aren’t clear.
This guide helps you split equity in a way that feels fair, reflects contributions, and protects your startup from future conflict.
Why it matters
- Early splits shape long-term trust 
 How you divide equity says a lot about how you value each other’s work.
- “Equal by default” isn’t always equal 
 Fair ≠ 50/50. Real fairness comes from clarity around effort, risk, and roles.
- A bad split can break a great idea 
 Misaligned equity leads to resentment, exits, and sometimes, shutdowns.
What equity actually means
Equity = ownership in your startup.
It means decision rights, future value, and long-term responsibility.
So don’t split it by gut feel or vibes.
Use real data: Who’s doing what? Who’s committing what? Who’s at risk?
What to do (before it gets messy)
- Talk about contributions honestly 
 Ask:- Who’s full-time vs part-time? 
- Who’s investing money or using their network? 
- Who’s building, selling, managing, funding? 
 - If roles aren’t equal, the split shouldn’t be either. 
- Use tools to guide the conversation 
 Try:- Slicing Pie 
- Founder's Pie Calculator 
 - These tools let you turn skills, time, and capital into numbers—so the process feels clear, not personal. 
- Add vesting to protect everyone 
 Vesting means equity is earned over time.
 Common structure: 4 years, with a 1-year cliff
 If someone leaves early, they don’t walk away with half the company.
- Put it in writing 
 At the very least, draft a shared agreement that includes:- Roles and responsibilities 
- Equity percentages 
- Vesting terms 
- What happens if someone leaves 
 - Even a Google Doc is better than a handshake. 
Quick checklist
You’re on the right track if:
- You’ve discussed roles and expectations openly 
- You’ve used a tool or framework to guide the split 
- You’ve agreed on a vesting plan 
- You’ve written down the agreement 
- Everyone feels respected and aligned 
StellarPH tip
