DevTools/Configuration Management and Automated SOC are two fairly significant example.

Am I the only one unimpressed by the dev tool situation? Debugging and verifying the generated code is more work than simply writing it.

I'm much more impressed with the advances in computer vision and image generation.

Either way, what are the startups that I should be looking at?

And even when the output is perfect, it may be that the tool is helping you write the same thing a hundred times instead of abstracting it into a better library or helper function.

Search/Replace as a service.

Those are more like broad categories than examples of startups, though.
