7 Contract Mistakes That Kill Startups

January 24, 2026 8 min read

Startups fail for many reasons—bad product-market fit, running out of money, team conflicts. But one silent killer that rarely makes headlines: contract mistakes. One bad agreement signed in the early days can haunt a company for years, or kill it entirely.

Here are 7 contract mistakes we've seen destroy otherwise promising startups.

⚠️ Mistake #1: No Founder Agreement

The #1 startup killer. Co-founders start building without defining equity splits, vesting schedules, roles, or what happens if someone leaves. When conflict arises (it always does), there's no framework to resolve it.

Fix: Get a founder agreement before writing a single line of code. Include vesting (typically 4-year with 1-year cliff), decision-making authority, and exit scenarios.

⚠️ Mistake #2: Giving Away IP to Contractors

You hire a developer to build your MVP. The contract doesn't include an IP assignment clause. Surprise: they own the code, not you.

Fix: Every contractor agreement must include explicit "work for hire" language and IP assignment. Have a lawyer review before signing.

⚠️ Mistake #3: Personal Guarantees on Business Contracts

Landlords and vendors often ask founders to personally guarantee contracts. If the startup fails, they come after your personal assets.

Fix: Negotiate to remove personal guarantees, or at minimum, cap them. Never guarantee more than you can afford to lose.

⚠️ Mistake #4: Exclusivity Clauses with Early Customers

An excited first customer asks for exclusivity in their industry. You agree. Later, you realize you just locked yourself out of 80% of your market.

Fix: Resist exclusivity. If absolutely necessary, make it narrow (geographic, time-limited) and expensive.

⚠️ Mistake #5: Signing VC Terms Without Understanding Them

Liquidation preferences, anti-dilution clauses, participating preferred—these terms can wipe out founders even in a "successful" exit.

Fix: Hire a startup-savvy lawyer to review term sheets. Understand how different exit scenarios affect founder payouts.

⚠️ Mistake #6: Auto-Renewing SaaS Contracts

You sign up for a tool with annual billing. It auto-renews without notice, charging you ₹5 lakh when you're broke.

Fix: Track all contract renewal dates. Negotiate for 30-day cancellation windows, not 90-day.

⚠️ Mistake #7: No Exit Clause in Partnerships

You enter a "strategic partnership" with a big company. The contract has no exit clause. Now you're stuck in a bad relationship with no way out.

Fix: Every partnership should have termination clauses for convenience (30-60 day notice) and cause (breach remedies).

The Common Thread

All these mistakes share one thing: founders signing contracts they didn't fully understand. In the excitement of early traction, it's tempting to just sign and move on. But contracts are legally binding—and ignorance isn't a defense.
