hiloop
hiloop is a San Francisco startup building infrastructure for automated research - the compute and observability layer that lets AI agents propose, run, and verify their own experiments. Teams hand hiloop a task, a model or agent, and a metric; hiloop runs snapshottable, forkable compute where every run is captured as a single queryable trace, then returns the best verified improvement across training, data, prompts, tools, and systems. Founded in 2026 by Karan Brar and Thomas Boser, it is part of Y Combinator's Summer 2026 batch.
