so many, here are a few that I think are pretty good and relate to skills/journey of a startup:

• The hard hard things by Ben Horowitz (great insight into what its like to run one)
• Venture Deals by Brad Feld and Jason Mendelson (explain VC term sheets if that is relevant)
• Who moved my cheese? by Spencer Johnson (better get ready to pivot, this is good for that)
• Crossing the chasm by Geoffrey Moore (great insight to think about your market)
• the Innovators Dilemma and the Lean Startup are good reads too (Christensen and Ries respectively)
