Your #1 competitor starting out will always be the BACK button, nothing else. – Garry Tan
Suppose you have an idea for a startup, and then do some research only to discover there are already similar products on the market. You become disheartened and wonder if you should abandon your idea.
In fact, the existence of competing products is a meaningful signal, but not necessarily a negative one. Here are some things to consider.
1) Almost every good idea has already been built. Sometimes new ideas are just ahead of their time. There were probably 50 companies that tried to do viral video sharing before YouTube. Before 2005, when YouTube was founded, relatively few users had broadband and video cameras. YouTube also took advantage of the latest version of Flash that could play videos seamlessly.
Other times existing companies simply didn’t execute well. Google and Facebook launched long after their competitors, but executed incredibly well and focused on the right things. When Google launched, other search engines like Yahoo, Excite, and Lycos were focused on becoming multipurpose “portals” and had de-prioritized search (Yahoo even outsourced their search technology).
2) The fact that other entrepreneurs thought the idea was good enough to build can be a positive signal. They probably went through some kind of vetting process like talking to target users and doing some market research. By launching later, you can piggyback off the work they’ve already done. That said, you do need to be careful not to get sucked into groupthink. For example, many techies follow the dictum “build something you would use yourself,” which leads to a glut of techie-centric products. There are tons Delicious and Digg clones even though it’s not clear those sites have appeal beyond their core techie audience.
3) That other people tried your idea without success could imply it’s a bad idea or simply that the timing or execution was wrong. Distinguishing between these cases is hard and where you should apply serious thought. If you think your competitors executed poorly, you should develop a theory of what they did wrong and how you’ll do better. Group buying had been tried a hundred times, but Groupon was the first to succeed, specifically by using coupons to track sales and by acquiring the local merchants first and then getting users instead of vice versa. If you think your competitor’s timing was off, you should have a thesis about what’s changed to make now the right time. These changes could come in a variety of forms: for example, it could be that users have become more sophisticated, the prices of key inputs have dropped, or that prerequisite technologies have become widely adopted.
Startups are primarly competing against indifference, lack of awareness, and lack of understanding — not other startups. For web startups this means you should worry about users simply not coming to your site, or when they do come, hitting the BACK button.
