This is a truly impressive undertaking.
However I wonder if there could potentially exist some trademark infringement on YC (regardless of whether they care or would even pursue any potential infringement.)
Part of the logo colors are similar, as well as the general concept of "startup accelerator", and most importantly the actual name.
From the site:
"We envision, incorporate, finance, support, and mentor a select number of startups that we are committed to make successful. Each startup is funded from the beginning for success, allowing the team to exploit new developments in physics, math, and the life sciences to create truly novel technologies and do the science enabled by being first."
I'm noting (after checking USPTO) that YC doesn't appear to have applied for a Federal trademark although obviously they quite clearly have the necessary common law rights and this name is certainly similar enough.
