BotGauge is an AI agent reliability platform that red-teams agents with adaptive attacks, traces every run, turns failures into evaluations and policies, and monitors agents in production; the company also runs an AI-led managed QA service.
Overmind is an open-source (AGPL-3.0) platform that turns AI agents' production traces into datasets, evals and fine-tuned open models you own, with observability, an MCP server and a hosted console.
TheySaid is a user-testing platform that runs usability tests with synthetic AI testers or real people and delivers findings and fix prompts inside tools like Claude Code, Cursor and Jira.
telemetry.dev is a hosted LLM observability platform built on OpenTelemetry that shows each AI agent run as one trace of model calls, tool steps and retrievals, with token, cost and latency tracking, MCP analytics, alerts, prompt management and evals.
Inferock routes LLM calls through a measurement layer that records quality, latency, cost and failed calls, and offers serverless and dedicated inference with service credits for eligible failures.

FoxPhone is a cloud phone platform: isolated Android devices in the cloud, each with its own device fingerprint and IP, built for AI agents to run at scale.

NitroStack is a platform for building, testing and hosting Model Context Protocol (MCP) servers. It combines an open-source TypeScript SDK, a desktop IDE called NitroStudio and a serverless host called NitroCloud.
Composio connects AI assistants and custom agents to more than 1,500 apps through managed authentication, SDKs and an MCP gateway, and its new Instant tools let agents pay per call for search, scraping, audio and data services from one balance.
