I recently gave a talk at NYU Startup School. The talk is pretty long, 1.5 hours and covers a really broad range of topics from types of investors to how VCs make money, from what do accelerators do to what preferred stock is, and more.
I really enjoyed this conversation, and hope you will find some of it helpful. The first 20 minutes is basically a crash course in all types of investors and sources of capital, will likely be most helpful.
Feel free to post any questions you have on these topics and I will gladly answer.
