I did not develop it but I worked as the UI/UX designer. I worked with start up companies and designed I'd Go Back, which is a social app. I also provided my services to Steadfast Innovation and worked with Squid which at the time was called Papyrus.

Mlungisi, Have you developed a software which is sold out to the people?

@Andrew. This is not a help question, its just a question which can be answered by anyone who had developed commercial software or game. @Juana Great job there.

Well I did develop one years back but there we some issues with the distribution as well as marketing so it didn't sell out but now I'm providing with a Software/Game piracy protection.

@Mlungisi I totally agree; marketing is super important. I feel I'd Go Back was not successful due to the lack of marketing. WOW!! Software/Game piracy protection... that sounds super!! I tried to do the UI/UX and animations for a game app and doing the animations was very painful to me hahahaha.

Creating an app/software is time consuming (research, implementation, marketing, distribution, feedback, repeat) and a good team is needed in order to be successful.

Indeed. But I think the problem is that especially in software we don't have something like a channel which we as developers could use to share our products because as of my case, the service that I'm providing is not for the end user/community but its for game developers/software developers so can you imagine the time it will take before it can reach them, but as of games its not complicated that much then software.

But marketing is the key whereas also building a channel is much more important as its simplifies the marketing effort that would be required before your product can sell out.
