Agnost AI helps teams building chat and voice AI agents understand what users want, where they get stuck, and why they drop off. We read production AI conversations, cluster recurring intents, feature requests, frustration, and failure patterns, then open PRs against prompts, tools, and harnesses to improve the agent.

Control Seat builds the hardware and software that helps industrial teams see, understand, and run their operations. Our platform creates one clear source of truth across the plant. It connects the systems teams already use, brings control, monitoring, history, and machine health together, and adds an intelligence layer that continuously watches for meaningful changes. Teams can understand what happened, catch problems earlier, and act before they become downtime. The result is fewer surprises, faster decisions, and less time spent piecing together information across disconnected tools. We work with manufacturers, utilities, energy companies, and other industrial operators modernizing existing facilities or building new ones.

Understand user patterns and find silent failures in your AI agents. The Context Company helps teams analyze AI agent conversations to surface user behavior patterns, performance trends, and moments where agents struggle - so teams know what’s working, what’s not, and what to improve next. We turn raw conversations into structured signals: topic clustering, user feedback analysis, custom pattern tracking, and alerts. All alongside traditional observability like traces, tool calls, latency, and costs. Get started in less than 10 lines of code.

Aravolta provides a single pane of glass software for data centers to increase uptime, reduce costs, and improve performance. A single utility node onboards every asset within an hour and detects hardware failures, hotspots, and other issues. It also generates reports on important metrics like Power Usage Effectiveness (PUE), energy metering, resource utilization, and much more.

Coval is a simulation & evaluation platform for autonomous AI agents, helping engineers launch dependable assistants across chat, voice, and other modalities. We simulate thousands of scenarios engineers don't have to manually test their agents. Our CI/CD evaluations automatically simulate and detect regressions.

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.

Monitor your AI agents the right way. AI engineers use Raindrop to get alerts about silent failures in their AI agents. Raindrop sends you alerts when your AI misbehaves and links straight to the events, so you can dig into the conversations or traces, understand the root cause, and fix it, fast.

Parea AI is the essential developer platform for debugging and monitoring every stage of LLM application development. We provide testing, evaluation, and monitoring in one unified platform. These capabilities help developers get visibility into LLM responses, quickly test and optimize prompts, and ensure customers get the best user experience.
