I think, now is not exist big enough niche for just ordinary compilers (tools) for cpu, after Eclipse there are only combine products, ide+compilers+tools in one. But mathematics is shared (or very similar) with ultra-focused and at the moment alive niches of tools for gpu, fpga, or even game engines and 3d render engines. For example, OpenGL community constantly struggle with tools issue, and people pay money for proprietary products or even switch to proprietary DirectX world. Similarly, game engines customers pay for customization. So I think it worth to try pivot, to some of these niches, or to other.
