Backed by Y Combinator

Agents that build your custom intelligence layer.

They curate your data, post-train open-weight models, evaluate and serve them. You own the weights.

01

Data curation

Traces, documents and logs into a clean training set.

02

Training

Fine-tuning to reinforcement learning, within your spend cap.

03

Evaluation

Every candidate graded in your own environment.

04

Serving

Download the weights, or use our OpenAI- and Anthropic-compatible endpoint.

Real screens from the Manifold workbench.

The recipe as a graph. Load, prepare, qualify, budget, train, export.

The agent reads the plan and names every gate. Each check passes before the next step runs.

One model serves the task. Promote a checkpoint. Your API call does not change.

Growth-stage startups

Pipe your traces into a model of your own

Point your agent's logs at Ashr. The agents qualify the traces, train, evaluate and hand you an endpoint. You keep shipping.

Research teams

A harness built for post-training

Your researchers set direction. The agents run on tested code with receipts and spend caps, instead of a general coding agent like Codex or Claude Code improvising the script.

Enterprise

Open-weight models on your infrastructure, without an ML team

Providers host the weights and run the jobs. Judgment, data curation and evaluation are still on you. Ashr takes that part.

“We wanted our research agents fine-tuned on our own tool sets. Ashr could start on that immediately, using data we already owned.”

Head of Engineering

“Our custom model tripled browser agent performance on EHR workflows at over 20 medical clinics.”

Mathieu RihetCEO, Novoflow

“Their post-trained model is what we run our world model evals against now, and it's way more accurate.”

Researcher, Berkeley

Own your intelligence.

Our engineers forward-deploy with the agents in your stack. The agents ship as a product after the first cohort.
