Agent debugging startup Laminar raises $3M seed to tackle the observability gap in AI agents

Laminar Secures $3 Million Seed Round to Revolutionize AI Agent Observability

In a significant development for the AI infrastructure landscape, Laminar, a cutting-edge observability platform designed specifically for AI agents, has announced a $3 million seed funding round. The investment was led by Atlantic.vC, with participation from Y Combinator, AAL.vC, and a host of notable angel investors including Ben Sigelman, co-creator of OpenTelemetry, and Ant Wilson, CTO of Supabase. This funding marks a pivotal moment for the company as it seeks to address one of the most pressing challenges in the rapidly evolving AI agent ecosystem.

The Founders’ Journey: From Kazakhstan to Silicon Valley

The story of Laminar begins with its co-founders, Robert Kim and Dinmukhamed Mailibay, who share a unique bond that dates back to their childhood in Kazakhstan. The duo later pursued their studies at KAIST, one of South Korea’s most prestigious universities, before reuniting in London to work on ambitious projects. Robert Kim built his expertise in infrastructure at Palantir and Bloomberg, while Dinmukhamed Mailibay honed his skills in payment infrastructure at AWS. Their shared vision and complementary skill sets eventually led them to co-found Laminar, and they were accepted into Y Combinator’s S24 batch, a testament to the potential of their idea.

The Problem: Traditional Observability Tools Are Failing AI Agents

As AI agents become increasingly sophisticated, the tools designed to monitor and debug them are struggling to keep up. Traditional observability platforms, which were built for single large language model (LLM) calls and simple chains, are ill-equipped to handle the complexity of modern AI agents. These agents can run for hours, generate thousands of spans per session, and require advanced debugging capabilities, such as browser session replay, to identify and resolve issues. Laminar was created to fill this critical gap.

The Solution: A Single Line of Code for Comprehensive Observability

Laminar’s platform is designed to be as seamless as it is powerful. With just a single line of code, developers can capture every action an AI agent takes, from LLM calls and tool usage to function executions. For browser-based agents, Laminar goes a step further by capturing browser session recordings and syncing them with traces. This allows developers to see exactly what the agent was interacting with at the moment a decision was made, providing unparalleled insight into the agent’s behavior.

Key Features: Signals and Agent Debugger

Two standout features of Laminar are its Signals and Agent Debugger capabilities. The Signals feature leverages AI to automatically identify failure patterns and anomalies at scale, transforming raw observability data into actionable insights. This creates a continuous improvement loop, enabling developers to refine their agents over time. The Agent Debugger, on the other hand, allows developers to rerun an agent from any step in its workflow while preserving full prior context. This eliminates the need to start from scratch when debugging, saving valuable time and resources.

CEO Robert Kim on the Vision Behind Laminar

Robert Kim, CEO of Laminar, articulated the company’s mission in a recent statement: “When your agent fails 40 minutes into a task, today’s tools show you a wall of thousands of spans and say ‘good luck.’ We built Laminar so you can pinpoint the exact decision that went wrong and rerun from that point.” This vision underscores the platform’s commitment to simplifying the debugging process and empowering developers to build more reliable AI agents.

Early Traction: Trusted by Industry Leaders

Since its launch in 2025, Laminar has quickly gained traction among industry leaders. Notable customers include Browser Use, OpenHands, Rye.com, and Alai. The platform’s SDK is directly integrated into OpenHands’ software agent and benchmarking infrastructure, and it is the default observability solution in Browser Use’s documentation. Multiple companies have chosen Laminar over incumbent platforms specifically for its Signals feature, and at least one well-funded AI company has built a similar capability in-house, validating the growing importance of agent-native observability.

Investor Confidence: A Critical Layer in the AI Stack

Lukas Erbguth, Principal at Atlantic.vC, expressed confidence in Laminar’s potential: “Robert and Din are technically exceptional and deeply customer-obsessed. Agent observability is a critical infrastructure layer for the next generation of AI, and Laminar has the right architecture to own it.” This endorsement highlights the strategic importance of Laminar’s technology in the broader AI ecosystem.

The Road Ahead: Scaling for the Future

With the new funding, Laminar plans to accelerate product development and expand its go-to-market efforts. As AI agents transition from prototypes to production at scale, the demand for robust observability tools is expected to grow exponentially. Laminar is well-positioned to lead this charge, offering a solution that is both innovative and essential for the future of AI.
