Hey Product Hunt 👋

I'm Kshitij, cofounder of Perit with my sister Poorva. We're both IIT Kharagpur alumni and second-time YC founders, now in YC F26.

Frontier AI labs have already trained on most of the public internet. What they need now is the data the internet doesn't have: real calls, real codebases, real work captured by the people who do it, and hard tasks written by people who know a domain inside out. A lot of that sits with startups, studios, agencies and domain experts who have no idea it's valuable.

So we opened up our marketplace. There are two ways in.

1. Own data? Submit it. Today the marketplace lists 29 datasets across 9 modalities, including 2.89M+ hours of audio, 4.74M+ hours of video and 21.1M+ lines of code. Audio, video, code, documents, images, CAD, clinical, enterprise workflows, anything.

Tell us the shape and the volume. A rough description is enough to start.
We come back with what it's worth and what clearing it would take.
We package it for the labs we work with.

2. Expert in a domain? Build RL tasks with Perit Expert Tasks. Experts write agentic tasks and benchmarks on our hosted workbench. Every task is stress-tested before we pitch it to frontier AI labs.

Simple upload. You add a task bundle and a weighted rubric, and it stays in a private workspace.
Seven quality gates. A task has to pass Build, Oracle, Do Nothing, New Seed, Difficulty Probe, Human Review and Publish before it goes live.
Calibrated difficulty. It only counts if frontier models pass it between 10% and 60% of the time.
Sandboxed and auditable. Every run is isolated, and every score traces back to the exact run that produced it.
Get paid. Experts are paid when a lab picks their task, and the best ones scale to hundreds of tasks.

To submit data, head to perit.ai/marketplace and click Submit your data. To build tasks, go to perit.ai/expert-tasks. Or drop a comment below with the data you have or the domain you know best, and our team will reach out.

Perit is a YC-backed company in the current F26 batch, and we're already working with multiple frontier AI labs. We've passed $11M in revenue. Poorva and I are both 2x YC founders, and Poorva previously worked at Google training their models. YC shared our launch here: our launch on LinkedIn

I'll be here all day answering questions and replying to every comment personally.
