Reinforcement learning post-training platform

market profile

  • text: Agent developers face compounding errors in multi-step tasks and repeated manual prompt fixes.
  • text: Specialized models can be trained for extraction, tool use and code generation, with continuous retraining tied to evaluations.

personas

  • title: Head of AI or applied ML
    pains:
    • Foundation model latency and inference cost undermine the economics of production agents.
    • Agent failures compound across long workflows.
  • title: ML engineer or post-training lead
    pains:
    • Reward function design and training infrastructure require specialized time.
    • Connecting evaluation feedback to reliable retraining is operationally difficult.
  • title: AI product engineering lead
    pains:
    • Prompt changes for each edge case do not produce durable learning.
    • Production tool use requires task-specific reliability.

icp

  • text: AI product companies deploying multi-step tool-using agents with evaluation data and measurable task outcomes.
  • text: Teams with recurring domain-specific extraction or code generation workloads and a reason to improve model cost, speed or accuracy; size is not specified.

message pillars

  • text: Offer specialized models with lower costs.
  • text: Remove training infrastructure work.
  • text: Keep models improving through evaluations and retraining.
  • text: Preserve customer model ownership.

objections

  • objection: Will a fine-tuned model beat our existing foundation model on our own tasks?
    response: Benchmark a held-out task set on quality, latency and total inference cost before committing to deployment.
  • objection: Are we locked into the vendor for serving?
    response: The company says customers can export their fine-tuned models for self-hosting; confirm terms and format.
