What Polar Signals does
Polar Signals is a continuous profiling platform founded in 2020 that provides zero-instrumentation, always-on production profiling of CPU, memory, and GPU workloads. The company's core technology is built on eBPF, enabling profiling with under 1% overhead and no code changes across Kubernetes, Docker, ECS, and bare metal environments. The platform extends beyond CPU/memory to NVIDIA GPU profiling via the open-source parcagpu library, which combines CUPTI, USDT probes, and eBPF for low-overhead production CUDA profiling, including instruction-level PC sampling. An AI integration layer is delivered through a remote Model Context Protocol (MCP) server with OAuth authentication, enabling natural language querying and autonomous code optimization via Claude Code, Cursor, Copilot, and Gemini, along with a VS Code extension and Open VSX distribution for Cursor, Windsurf, and Antigravity.
The product surface includes the hosted Polar Signals Cloud SaaS platform, the open-source Parca project (with parca-agent, parcagpu, parca-debuginfo, parca-push, and pprof.me), a Prometheus-style query language, flame graph visualization, and side-by-side profile comparison with regression detection. The company operates a product-led growth go-to-market with a 14-day free trial and single kubectl command deployment, supplemented by an enterprise sales motion, Google Cloud Marketplace listing, and a Chronosphere partner ISV integration. Pricing is usage-based on profiling data volume, billed monthly. Polar Signals serves engineering teams and ML practitioners at technology companies, with named customers including Vercel, Materialize, Thought Machine, Notion, Zalando, Weaviate, Langchain, OQTON, Modal, Turbopuffer, and Authzed. The company is remote-first, headquartered in the US, venture-backed with $10.8M raised across two seed rounds (2021 and March 2024 led by Spark Capital), and maintains AICPA SOC compliance.

Polar Signals product offering
Product offeringCore offering
Polar Signals operates a continuous profiling platform that provides always-on, low-overhead visibility into production code performance using eBPF-based zero-instrumentation profiling. The platform supports CPU, memory, and GPU profiling (including NVIDIA CUDA workloads) and integrates with AI coding assistants through a Model Context Protocol (MCP) server to enable natural-language queries and automated code optimization suggestions.
Product overview
Polar Signals offers a unified continuous profiling platform comprising Polar Signals Cloud (the primary hosted SaaS product), the open-source Parca project for self-hosted deployments, and a suite of specialized agents and tools. The core platform uses eBPF-based parca-agent for zero-instrumentation profiling, supplemented by parca-debuginfo for symbol upload and parca-push for direct data submission. AI capabilities are delivered through the Polar Signals MCP Server enabling natural language queries via Claude, Cursor, and Gemini. GPU profiling is provided via the parcagpu library with CUPTI integration for NVIDIA GPUs. The VS Code Extension brings profiling annotations directly into the development environment. Additional tools include pprof.me for public profile sharing.
