In the world of early stage investing, there exists a range of structures from the most founder friendly to the most investor friendly. 

The most investor-friendly structure involves some type of a priced round in which the investor receives shares of a class of preferred stock with a negotiated set of enhanced economic, management and exit rights.  These rights and other terms are memorialized in a group of governance documents and agreements among the company, the investors and the founders.

On the other hand, the most founder-friendly investment structure is the simple agreement for future equity, or SAFE, which is similar to a convertible note but notably lacks an interest component and a maturity date.  Next along the range of investor friendliness is the convertible note, which contains several investor protections, including interest, maturity, some reps and warranties and (sometimes) security.  In the real world, however, more sophisticated investors routinely augment their protection under both SAFEs and convertible notes by negotiating side letters that provide them with more enhanced rights.

Documentation for priced rounds and SAFEs have benefited from standardization.  The National Venture Capital Association website open sources a set of standard Series A documents which are a convenient starting point for initial VC rounds.  Ted Wang of Fenwick & West developed a set of standard Series Seed documents in 2010 for use in lower dollar amount priced rounds.  Gust Launch, a SaaS platform for founding, operating and investing in startups open sources a slightly more elaborate set of Series Seed documents.  And Y Combinator, which created the SAFE, open sources its several varieties of the SAFE on its website.  Only convertible notes have lacked standardization and the efficiencies that come with it.Continue Reading Planting Seeds:  New Standard Convertible Note Could Disrupt Angel Investing
