We've been using SourceForge for years to find the best software for our business, whenever the need arises. SourceForge has done a great job building a comprehensive business software directory that lets you filter by remarkable granular criteria. So, for example, when we needed a new email marketing tool, we turned to SourceForge and input our needs and found a great tool that we now use every day.
When we launched our own software product, I figured we'd list it on SourceForge to get some exposure, and we even signed up for one of their paid plans. The results blew my mind. For the price, we get so many more qualified leads than any other business software site we advertise on. SourceForge is the best kept secret (maybe not for long) in the business software advertising world. If you want to acquire new customers for your software or SaaS product, then SourceForge need to be at the top of your list.
They also have a great open source software directory and repository, because sometimes open source software is the best choice, depending on what you need. Highly recommend.
