This week I have been talking about some of the popular early-stage startup founding vehicles. On Monday we talked about convertible notes and on Wednesday I covered the more popular SAFE funding option.   While the SAFE was created by the folks at Y Combinator, the Keep in Simple Security, or KISS, funding vehicle was created by another popular incubator team at 500 Startups.   This funding option is also designed to make the use of convertible notes even more simple, as the name eludes to.   What is a Keep it Simple Security?   The KISS is even more focused on simplifying the startup funding process through convertible notes by making the legal  process of closing such a deal easier.   One of the biggest expenses in closing a round of funding with an investor can be the legal costs associated with the deal. The KISS documents were specifically designed to be open sourced, short (less than ten pages in length), and extremely flexible.    My one concern is that with the flexibility you often leave the opportunity for each side to add too much customization to an agreement. Hopefully, the team has addressed this by limiting the conditions that can be added to the document.   I did note that the KISS legal documents come in two separate formats. One each specifically for debt-based or equity-based funding rounds.   Next up   Normally I have my episodes all scheduled out in advance. But next week that isn’t yet the case. So, here is your chance to request topics you’d like to see me cover. Tag me over on Twitter if you’d like to suggest a topic.
