Startup Equity Negotiation Scripts: What to Say at Every Stage

Don't leave equity on the table. Use these proven scripts to negotiate your ownership stake from co-founder discussions through Series A.

Negotiating equity is uncomfortable. Most founders default to "50/50 split" or "whatever the investor wants" because they don't know what to say. This costs them 5-15% of their company—millions at exit.

These scripts work. They're based on real negotiations from founders who've raised $500M+ combined. Use them as templates, adjust to your situation, and never go in empty-handed again.

The "Equal Split" Pushback

Scenario: Your co-founder insists on 50/50, but you're doing 80% of the initial work.

The "Idea Guy" Claim

Scenario: Co-founder claims they deserve more equity because "it was my idea."

The "Standard Market Terms" Pressure

Scenario: Investor says "these are standard terms" when pushing for aggressive liquidation preference or board control.

Option Pool Sizing Negotiation

Scenario: Investor wants a 20% option pool created before their investment (meaning you and founders get diluted by it).

Anti-Dilution Request

Scenario: You want protection against a down round in the future.

Participating Preferred vs. Non-Participating

Scenario: Investor pushes for participating preferred (they get their money back plus their equity share at exit).

Board Seat Request

Scenario: Investor demands 2 board seats, leaving you with minority control.

Pro-Rata Rights Negotiation

Scenario: You want the right to maintain your ownership percentage in future rounds.

🎯 Universal Negotiation Principles

These principles apply at every stage. Internalize them before any equity conversation.

1. Know your BATNA — Best Alternative to a Negotiated Agreement. What happens if you walk away? Having a strong alternative gives you leverage.
2. Anchor with data — Use benchmarks. "At this stage, founders typically own X%" is stronger than "I think I deserve Y%."
3. Trade value for value — Never give concessions. If you give up something, get something back. "I'll accept that liquidation preference if you drop the participating preferred."
4. Get it in writing — Handshakes mean nothing. If it's not in the term sheet or cap table, it doesn't exist.
5. Relationships matter more than any single term — Don't burn bridges for 2% more equity. Negotiate hard, but stay respectful.

📊 Before You Negotiate: Know Your Numbers

Walking into a negotiation without modeling your dilution is malpractice. Use FounderMath's dilution calculator to see exactly what happens to your ownership across rounds.

Then use the Founder Equity Score to compare your proposed deal against industry benchmarks. A 65/100 score means you're below average—negotiate harder. An 85/100 means you're in good shape.

❌ Common Negotiation Mistakes

🔥 The Nuclear Option: When to Walk Away

Sometimes terms are so bad you should walk. Here's when:

• Liquidation preference > 1x — You're building the company but they get paid back multiple times before you see a dime.
• Participating preferred at Series A — Creates misaligned incentives. They want early exits; you want to build.
• Board control loss at early stage — If you lose board control at seed/Series A, you're effectively an employee.
• Full ratchet anti-dilution without cap — Punishes you unfairly for future rounds you can't control.
• No vesting for co-founders — If someone leaves with 30% after 6 months, your company is dead.
