That's your favorite tech startup book. Oh, there's just so many, um, differently. Eric Reese's lean startup is great. Um, Brad Feld has a Venture Deals book. That's good. Let's see what else would be a great one? Um John Collins Book from Good to Great Crossing the Chasm. Jeffrey Moore. Uh, those air, probably probably good of the couple in their general business books, but apply largely to start up. Spend Horwitz hard things about the hard things is is also a great one.
