5 clauses founders almost always leave out of their contracts

Most contract mistakes aren't about what's in the document.
They're about what's missing.

After writing 80+ contracts for my own company, these are the ones that came back to bite me or someone I know every single time.

1. Deliverable definition
   "20 reels in different outfits and locations" sounds specific. It isn't. If you don't define the numbers, the other party defines them for you.

2. Revision limits
   You hired a designer. They send version 1. You ask for changes. And again. And again. Without a revision cap in the contract, that's unlimited free labor you just promised yourself.

3. Force Majeure
   Almost never likely to happen but could. Look at Covid? Half of the factories or supply chain was delayed/slowed. Even now with the Iran war. Protect yourself by adding a force majeure clause.

4. IP ownership upon non-payment
   Work gets done. Invoice goes unpaid. Without this clause, the contractor may still own what they built for you until you pay. Most founders find this out too late.

5. Auto-renewal
   SaaS tools, agency retainers, vendor agreements. If there's no notice period defined, you're locked in for another cycle whether you meant to be or not.
   None of these require a lawyer to get right. They just require knowing they exist before you hit send.

That's the whole problem we're solving at Claustar. Launching next week.
