When you start a business, you need to be a raging optimist. That's because, frankly, it's hard and many people don't succeed. So to stand a chance, you really need to have a sunny view of the future.
However, you also need to be a realist. A friend of mine was working in a new start up. He asked me if I was interested in investing, so I took home a sample of his product. In the meantime, he had managed to place it with a couple of major high street chains. I tried it with my wife and daughter who were in the target market. Neither of them liked it, so I declined to invest.
The business in the meantime continued. A while later they were back to the drawing board, because the product hadn't sold through the retail channel at all and had been dropped by the retailers. Fortunately they have now completely changed the offering and are doing okay, albeit on a much smaller scale. My friend is no longer involved.
Another business planned to sell a website monitoring service to small companies. After a few months of selling, it was clear there wasn't much of a market. The management team changed direction and started selling to big corporate sites instead. This was a raging success and several years later they still have a razor focus on the same market. I was happy and this time invested in the company when they changed direction.
What are the lessons from these stories? It's about realism and facing the facts. The lesson isn't to chop and change, as the second company had to stay their new course for several years. However, the quicker you face difficult facts the better, particularly when it comes to customers.
The most important thing any start-up can do is to get some happy, paying customers. If the prospects won't buy or don't like the product after they do, don't try to tell them how they're wrong. Instead, change direction and provide something that they want. Then press on. A dose of realism is worth a ton of investment. In fact, having the money to continue backing a losing strategy can be the biggest disaster.
