Company Overview
About Solo.io
Solo.io is a cloud-native infrastructure software company that builds enterprise-grade API gateway, service mesh, and AI gateway products for platform engineering and DevOps teams. Founded in 2017 by Idit Levine and headquartered in Cambridge, Massachusetts, Solo.io is best known for its Gloo product family and its role as a co-creator (alongside Google) of the Istio open-source service mesh — which has become the de facto standard for microservices networking in Kubernetes environments. Solo.io provides enterprise support, hardened distributions, and advanced features on top of open-source Istio, enabling large organizations to run Istio in production at scale with enterprise SLAs.
Business Model & Competitive Advantage
Solo.io''s product portfolio includes Gloo Gateway (an API gateway built on Envoy Proxy), Gloo Mesh (enterprise Istio management with multi-cluster support), and Gloo AI Gateway (security and governance for LLM API traffic). In 2026, the company donated its open-source Gloo Gateway project to the CNCF (Cloud Native Computing Foundation) as the kgateway project, deepening its open-source credibility. Solo.io also launched Agentgateway — a high-performance, Rust-based gateway purpose-built for agentic AI workloads, now a Linux Foundation project — positioning the company at the intersection of cloud-native infrastructure and the emerging AI agent ecosystem.
Competitive Landscape 2025–2026
Solo.io has raised significant funding from investors including Redpoint Ventures and New Enterprise Associates. It competes with Kong, Apigee (Google Cloud), AWS API Gateway, and Traefik in the API gateway market, and with managed Istio offerings from cloud providers in the service mesh segment. Its open-source roots, CNCF involvement, and early positioning in AI agent infrastructure make it a significant voice in cloud-native architecture.
