My heart sinks every time I hear a would-be-entrepreneur announcing they have written yet another Twitter client, RSS reader, ToDo list or backup application. Haven’t we got enough of those already? There are more than 1,900 Twitter apps already (possibly a lot more). Somebody probably released another one while I was writing this post. We have passed the Twitter app event horizon, where it is probably quicker to write your own custom app than it is to try and work out if any of the existing apps fulfils your requirements.
Even if you have done something radically new, interesting and different in one of these markets, how are you ever going to get noticed amongst thousands of more established competitors? Wouldn’t it be better to find a market that is currently under-served by software? It may be less fashionable than writing software for other techies, but it will probably contribute more to the sum of human happiness and be a lot more profitable.
There must be thousands of niches where there is a real need for software, but limited competition. You just need to open your eyes to the bigger world around you. It may mean having to learn about an unfamiliar domain. But it is generally much easier for a software developer to learn some domain knowledge about, say, butterfly collecting, than it is for the average butterfly collector to learn to create a software product. Next time you are talking to a non-techie about their job or hobbies, just ask them “Do you use software for that?” and “Is it any good?”. The ideal answers you are looking for are “Yes” (if there are existing software packages, there is probably a market) and “No” (maybe you can do better).
