ReasonBlocks GTM brain

ReasonBlocks helps AI engineering teams evaluate agent readiness using traces, evaluations and launch evidence.

category

AI agent evaluation and optimization

market profile

  • text: Teams deploying agents need visibility into evaluation coverage, risks and production readiness.
  • text: The YC profile also describes specialized models trained from production traces to reduce inference cost.

personas

  • title: AI engineering lead
    pains:
    • Agent behavior changes across tasks and is difficult to assess before launch.
    • Teams need evidence to decide whether quality holds when switching to cheaper models.
  • title: ML platform engineer
    pains:
    • Production traces and evaluation results are scattered across tools.
    • Inference costs grow as agent usage and model calls increase.
  • title: AI product owner
    pains:
    • Launch decisions are hard to defend without a clear view of unresolved risks.
    • Failures in agent workflows undermine user trust.

icp

  • text: Software companies with AI agents in production or preparing a production launch.
  • text: Teams with existing agent traces or evaluation datasets and a meaningful inference budget.

message pillars

  • text: Make agent progress visible.
  • text: Surface risks and launch evidence.
  • text: Use existing evaluations or construct them from traces.

objections

  • objection: We already run our own evaluations.
    response: Assess whether a shared view of evaluation evidence and risks adds value to the existing process.
  • objection: Lower model costs could hurt quality.
    response: Benchmark on representative traces and compare quality before changing production routing.
  • objection: Our agent framework is custom.
    response: Confirm integration and data handling in a small technical pilot.
