The success rate of startups varies greatly depending on the industry or "idea pool." I am interested in forgotten industries where there is little to no software being used in various processes, or where ancient pieces of software are still being utilized.<p>Can you think of any ancient software that is still actively being used or purchased in niche industries? Ideally, this software is not tied to specific hardware, making it more accessible for outsiders to develop.
Random advice from the internet.<p>If you look at business software, think it is crappy, and wonder why people use it; you probably don't understand the business reasons behind the decision.<p>As the business becomes more niche, the more likely it is that you don't understand.<p>But the high level bit is always that the software is incidental to the business, not its core. It is a cost center not a source of revenue. Stable cost centers can be plugged into budgets and cash flow analysis.<p>Which is to say, "your software is old" is not a business case that will drive sales.<p>Good luck.
