I spend a lot of time thinking about potential start up ideas. I come up with a couple every now and then, but when I go searching online there is always quite a few competitors. I don't think I've come up with an idea that no one has already thought of. Because of this I've been deterred from starting anything. Now I'm thinking I should look at the competition and decide if it is worth competing in the idea space. What should one look for when trying to determine if it is worth competing in an idea space?
For example, I recently thought of innovative support software, but when I looked around I found that sites like Zendesk and Snap Engage (and probably quite a few more) are already implementing the things I was thinking of doing. Based on the quality of those products, and the amount of competitors, it doesn't seem like a space that is worth trying to compete in.
