Self-driving observability, evals, and gateway for AI agents

Respan (formerly Keywords AI) gives teams a unified control plane to trace and evaluate agent behavior without guesswork, automatically surface issues, and fix what breaks faster. Respan connects production observability, automated and human-in-the-loop evaluations, and an adaptive AI gateway to close the loop between detection, decision, and action - so agents improve continuously in production. Respan is trusted by 100+ AI startups and enterprise teams. Today, the platform process 1B+ logs and 2T+ tokens every month, supporting more than 6.5M end users.

‼️ The Problem

LLM developers face many challenges that hinder the ability to quickly build and scale high-quality products that people love:

  • Time-consuming infrastructure setup and maintenance for deploying and scaling LLM applications

  • Difficulty collaborating on prompt engineering and evaluating models for specific use cases

  • Challenges monitoring and ensuring consistent performance in production for optimal user experience

  • Tedious process of creating datasets for fine-tuning and iteratively improving output quality

🤠 The Team

Andy and Raymond both studied mechanical engineering at UIUC and have been best friends since college.

Andy took a gap year to work as a product design engineer at Apple after freshman year, where he designed parts for the next-gen & next-next-next-gen AirPods. He dropped out after realizing his dream job wasn’t that fun.

Raymond is so good at learning things. He graduated with the highest honor in just three years and self-mastered software engineering within a year. He dropped his robotics PhD offers from top schools.

We’ve worked on a bunch of very bad ideas together in the past year. Now we think we've stumbled upon a good one :)
