At Denver Startup Week we caught up with Mark Cuban and had a blunt talk about his annoyances, the stupid things startups do when pitching for money and the importance of sales. How much politics played into buying decisions in big companies.  I would not have wasted so much time chasing big name accounts. Business is the most competitive sport there is. If you can’t take a hit and rebound you won’t survive. No one in your industry is just going to let you take their sales from them. You have to realize it’s a never-ending battle. The relationship with your employees. They must understand your vision and goals and you need to understand theirs. When you realize how to put your employees in a position to succeed they will help put the company in a position to succeed. Knowledge. Effort. Wisdom. They have to know their industry, know their customers and understand what it takes to make their customers happy. Trolling for media appearances. Too many see it as a shortcut to sales rather than working to build a strong sales foundation. So many. One time we had an employee embezzle 82k of the 84k we had in the bank. She literally whites out the payee on our accounts payable checks and the bank cashed them. I haven’t seen her since. We had failed to protect ourselves. We had to regroup, talk to our vendors to work out a payment plan and recover quickly. It motivated me to work not just harder but smarter and not skip administration steps that were important.
