What is Series Seed?

Series Seed is a standardized set of legal documents that can be quickly and easily deployed for a seed investment round. This collection was developed by Cooley LLP and represents a streamlined approach to seed financing that balances the interests of both entrepreneurs and investors.
The Series Seed documents are designed for seed rounds typically ranging from 250Kto250K to 2M, though they can be adapted for different amounts based on your specific needs.

Key Features

Simplicity and Speed

The Series Seed documents are intentionally straightforward, avoiding unnecessary complexity that can slow down early-stage financings. They provide essential protections while minimizing negotiation time.

Balanced Terms

These documents reflect “market” terms that are generally fair to both founders and investors, incorporating lessons learned from thousands of seed financings.

Automated Document Generation

The documents are available through automated document generators at:

Document Sets Available

Series Seed includes two primary financing structures:
Used when investors purchase preferred stock directly:
  • Term Sheet (Equity)
  • Preferred Stock Investment Agreement
  • Restated Certificate of Incorporation
  • Board Consent
  • Stockholder Consent
  • Investor Questionnaire
Used when investors provide debt that converts to equity later:
  • Term Sheet (Convertible Note)
  • Convertible Promissory Note
  • Board Consent
  • Investor Questionnaire

When to Use Series Seed

Consider using Series Seed documents when:
  • Raising your first institutional capital (seed round)
  • Seeking a balance between founder-friendly and investor-protective terms
  • Working with professional angel investors or seed funds
  • Looking to close quickly without extensive legal negotiations
  • Raising between 250Kand250K and 2M (though adaptable)
While Series Seed documents are designed to be straightforward, they still create legally binding obligations. Always consult with qualified legal counsel before using these documents.

Comparison with Other Options

Series Seed vs. SAFE

While Y Combinator’s SAFE (Simple Agreement for Future Equity) is simpler and faster, Series Seed equity documents provide more structure and immediate investor rights, which some investors prefer.

Series Seed vs. Full Series A

Series Seed documents are lighter than typical Series A documents. They have fewer protective provisions, simpler governance structures, and less extensive representations and warranties.

Key Terms Overview

Series Seed typically includes 1x non-participating liquidation preference, meaning preferred stockholders receive their investment back before common stockholders in a liquidation event.
Board structure is negotiable but typically includes founder representatives and may include one or more investor representatives depending on the round size.
Major Purchasers (those investing above a specified threshold) receive annual and quarterly financial statements and inspection rights.
Major Purchasers have pro rata rights to participate in future financing rounds to maintain their ownership percentage.
If approved by required majorities, all stockholders must participate in a sale of the company on the same terms.

Source and Attribution

The Series Seed documents are maintained by Cooley LLP and are available as open-source resources. The current version (v3.2) reflects updates and improvements based on market practice and feedback from the startup community.

Getting Started

  1. Determine your financing structure: Equity vs. convertible note
  2. Review the term sheet: Understand key economic and governance terms
  3. Consult with counsel: Have experienced startup counsel review terms
  4. Generate documents: Use the automated tools with your specific terms
  5. Execute and close: Sign documents and receive funding
The Series Seed documents are designed to work together as a complete package. Modifying individual documents without considering the entire set may create inconsistencies.
