FYI your life is now complete: The Entrepreneur’s Guide to Customer Development t-shirts have arrived.
Steven of CargoHawk has put together a suite of startup-themed t-shirts that I suggest you check out.
One of my favorite analytics tools, Crazy Egg, has it’s own shirt.
Notable investor and great blogger, Bred Feld, has Feld Thought t-shirts available too.
As well as a bunch more. If you have a startup or startup themed project and want to promote yourself via t-shirts — get in touch with Steve.
