Respan, formerly Keywords AI Inc., has raised $5 million in seed funding to launch a proactive AI observability platform. The system deploys an automated evaluation agent that identifies regressions, pinpoints root causes of agent failures, and recommends prompt updates or new evaluations.
As AI agents proliferate, stability demands more than retrospective tracing. Respan’s platform integrates in minutes with existing frameworks, models, and languages-providing full visibility into non-deterministic agentic behavior.
The evaluation agent uses third-party foundation models-deliberately distinct from the agent’s own model family-to avoid bias. Customers configure it at low temperature for conservative, deterministic outputs.
Alerts fire via Slack, email, or text across dev, staging, and production environments. Backers include Gradient, Y Combinator, Hat-Trick Capital, Xiaoxiao Fund, Antigravity Capital, Alpen Capital, and prominent AI founders.
Respan now prioritizes engineering hires and infrastructure reliability, serving over 100 startup and enterprise teams.
