Pulsent continuously watches how your users and interacts with your product and engages them at the right moment to convert, upsell, and retain. As companies scale, founders, account managers and customer success teams can only take care of a small fraction of users. The rest receive generic, annoying and poorly timed communication. Opportunities are missed, customers churn, and revenue is lost. The core problem is that user behavior is fragmented across tools like PostHog, Stripe, Salesforce, etc., making it impossible to understand users in real time. We unify all data into a single view and let AI agents act on top. This only recently became possible with advances in visual AI (dec ‘25), allowing agents to watch sessions and understand behavior at human or better level. Pulsent detects expansion and churn signals, prioritizes high-value accounts, and executes through AI agents across channels like email, LinkedIn, and WhatsApp. It increases conversion and reduces churn without adding headcount. We already have paying customers, process hundreds of millions of events daily, and are seeing strong demand from PLG B2B Clients. Nicolò is an ex-BCG who has scaled two startups to millions in ARR. Arseniy worked for several years at Datadog handling billions of datapoints. We’ve worked together for 3+ years and experienced this problem firsthand in our previous startup.

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.
