Most the tools today didn't exist when I started. At each point in time I looked up and didn't see a better tool. The initial competition was focussed on DBA tasks, my colleagues and I mostly analyse large data. So we don't perform a lot of DBA tasks or manual editing of data (it's too large for that). We mostly select or create new tables that are cleaned up version using coded fixes.

There are better tools now, partly why qStudio is free as I don't believe it could compete with the paid offerings. My main profit making focus has moved onto a new niche that I think is underserved....building real-time apps based on a database. qStudio acts as a good advertisement and brand awareness for that much heavier product.
