What Tetrate does
Tetrate is a private infrastructure-software company founded in 2017 and headquartered in Milpitas, California, that builds enterprise service mesh and AI gateway products on the CNCF Envoy Proxy. Its core platform, Agent Router, provides a unified AI gateway across 16+ LLM providers (OpenAI, Anthropic, Google Gemini, Azure OpenAI, AWS Bedrock) through an OpenAI-compatible API, with capabilities including automatic failover, token-aware rate limiting, per-team and per-agent cost attribution, MCP Gateway for secure agent-tool connectivity, and runtime AI Guardrails for PII redaction and prompt filtering. The company co-created Envoy AI Gateway with Bloomberg, the first CNCF-backed open-source AI gateway, which reached v1.0 production maturity in June 2026 and serves as the foundational data plane for Tetrate's commercial products.
Tetrate generates revenue primarily through enterprise subscription licenses for Agent Router Enterprise, Tetrate Enterprise Gateway for Envoy (TEG), and Tetrate Istio Subscription (TIS/TIS+), with additional recurring revenue from Standard and Premium technical support tiers carrying SLAs and project-based revenue from forward-deployed professional services. A free self-serve developer tier (Agent Router Service) supports a product-led growth motion aimed at individual developers, while enterprise sales are driven through direct field engagement, demo booking, and cloud marketplace listings on AWS, Azure, and the Red Hat Ecosystem Catalog. Its target buyers are enterprise platform engineering teams, financial services firms governed by FINOS AI Governance and NIST standards, US federal and defense agencies requiring FIPS-verified and FedRAMP-Ready builds, and cloud-native organizations running multi-cluster Kubernetes. Notable customers include Bloomberg, Nutanix, Tencent Cloud, LY Corporation, the US Air Force ($1.75M contract), and Ory.
The company has raised $52.5M across two disclosed rounds (a $12.5M round in March 2019 led by Dell Technologies Capital and a $40M Series B in March 2021 led by Sapphire Ventures with 8VC, Dell Technologies Capital, Intel Capital, NTT Venture Capital, Samsung NEXT, and Scale Venture Partners). Tetrate maintains 101-250 employees, active governance roles within CNCF and FINOS, and an open-source stewardship position over Envoy Proxy and Envoy AI Gateway that anchors its commercial moat in regulated and large-enterprise procurement.
