YC Summer 2026 (S26) founder

Karan Brar

Founder of hiloop, Autoresearch as a service: we solve your hardest measurable problems

Company

Karan Brar is listed as a founder of hiloop. hiloop helps teams train agents for tasks where general models are not good enough. Give us a task, your current agent or model, and an evaluation. hiloop runs an autoresearch campaign across data, SFT and other post-training methods, continual learning, prompts, tools, harnesses, and systems, then returns the best verified improvement. It runs hosted or in your cloud. We provide the research system around models: persistent memory, full experiment lineage, compute orchestration, and statistical verification. We’re starting with agent and model training, continual learning, and optimization. Reach out to us for early access at founders@hiloop.ai.

    Simple example but I’m excited about autoresearch x robotics.

    Simple example but I’m excited about autoresearch x robotics. Results from our harness + fable 5 and Sol to the prompt “wave at me”

    It’s quite annoying that people can’t just have a nuanced take.

    It’s quite annoying that people can’t just have a nuanced take. I’m not sure any of these results are Fields medal worthy. That doesn’t take away from the accomplishment but like please stop. ASI is almost surely not here.

    My brother you’ve turned all of meta into a data sweatshop, let’s not talk about doing things for commercial convenience

    for when @_vatsadev graduates, he's smarter that most researchers I've met, already high intercept and high slope!
