My problem is kind of weird so please bear with me.

I have been working in a start up concerned basically with mobile development since my graduation 2 years ago. I develop apps for iOS but it's not really relevant. The start up structure is simply founders > developers, with no middle-tier technical supervision or project management whatsoever.

A typical project cycle of ours is like this: meet with a client > send very vague recruitment to an outsourced graphics designer > dig in development right after we get the design, no questions asked > then improvise improvise improvise! It's not that we are unaware that stuff like requirements analysis, UML, design patterns, source code control, testing, development methodologies... etc. exist, we just simply don't use them, and I mean like never.

The result is usually a clunk of hardly-maintainable yet working code. Despite everything we are literally flourishing with many successful apps on all platforms and bigger clients each project. The thing is, we want the chaos and we're looking for advice.

How would you fix our company technically? Given that you can't hire project managers or team leaders just because we are barely 5 developers, so it wouldn't be a justified cost for the founders, but one-time things like courses, books, private training... etc is an option. Lastly, if it's relevant, we are based in Egypt.

Thank you a lot in advance.
