Series Seed Equity & Series Seed Notes

About Series Seed Documents

The original "Series Seed" equity financing document sets was a collaborative effort among lawyers and investors, spearheaded by lawyer-turned-investor Ted Wang, to reduce the cost of fundraising for emerging companies by standardizing the core necessary legal documents, thereby reducing the amount of attorney-time required to get to a "first draft." While the original project did not create the concept of “Series Seed Preferred Stock,” it did provide a set of documents to the community under CC0 open source license via the Series Seed blog and in a GitHub repository that have become one of the "go-to" sets of documents for many early-stage equity financings. In addition, convertible promissory notes remain popular for early-stage financings, although to our knowledge there is no publicly available and commonly accepted "form" of convertible promissory note documents.

About Cooley's Series Seed Fork

"Seed Note" Convertible Debt Financing Documents Series

Issuing convertible notes is one of the most popular ways for startups to raise initial seed funding. Cooley uses these documents in hundreds of transactions each year for its startup clients and believes making these documents publicly available adds efficiency to the early-stage startup funding ecosystem and provides entrepreneurs and the community at large the opportunity to collaborate to ensure they evolve with the needs of entrepreneurs and investors.

In the open source spirit of the Series Seed project, we have made available to the wider community a Series Seed Notes package, which includes a convertible promissory note, term sheet and supporting documentation, as an addition to our "fork" of the original Series Seed equity financing documents repository. The Cooley form of convertible note has been structured so as to avoid the need for a separate note purchase agreement, thereby simplifying the documentation. The Series Seed Notes package is available in the notes directory of our Series Seed repository on GitHub.

Series Seed Equity Documents

At the same time, we wanted to contribute back to the original Series Seed equity documents a number of refinements and features, many of which address community comments made in the original GitHub repository, since the last-released version of Series Seed equity documents (v3.2) as well as adding supporting documents (namely Board and Stockholder Consents and an Accredited Investor Questionnaire). These changes and documents may be found in the equity directory of our Series Seed repository fork on GitHub.

We will review suggested updates to all of this documentation, and periodically release new versions when appropriate.

Please see the "Original Text", below, for the README text that was included in the original, master Series Seed Repository, which contains additional information and an important disclaimer.

Series Seed Document Generation via Cooley GO

In addition to the Markdown versions included in this repository, the Series Seed equity and notes documents available for generation as packages via our Cooley GO Docs document generator. This system enabled entrepreneurs, investors and other lawyers to create fully customized versions of these documents in a matter of minutes. We endeavor to ensure that the documents available on Cooley GO Docs are kept in sync with those in this repository.
