Seed activity in this category runs heavily through the accelerator ecosystem and the funds that follow its cohorts. The AI build-out has made developer tooling one of the fastest-moving early stage categories in the market. For a company raising at this stage, these are the highest-velocity check writers in the category, and the accelerator and syndicate paths are often the most direct way to reach them.
