Assuming they have some kind of beta, do whatever it takes to figure out sales by yourself. This is one of the reasons PlanGrid has been so successful.After YC, we brought on a VP of Sales, but he couldn’t sell the product. At the end of the day, we knew the product best, we knew why it would add so much value to our users. Who better to sell the product than the founding team?We didn’t want our company run by a salesperson. We went out, talked to users, figured out how and when they would pay us, and got to that point.It’s nice not to have to rely on fundraising to sustain the company. It’s nice to have months where we’re cash flow positive. Figure out how to get to that point with just the founding team. You can’t rely on others to sell the product you built.
