Solo.io develops a cloud‑native platform that combines an API gateway and service mesh into a single control plane, notably via its Gloo Mesh product. The company was an early contributor to the open‑source Envoy proxy and Istio service mesh and builds commercial products on top of those projects. Solo.io was founded in 2017 and has grown its team to around 70 employees. Management says FY2021 ARR was on track to triple year‑over‑year by the end of Q2, and the company has signed over 100 contracts, with 35% of deals spanning two to three years. CEO Idit Levine says the firm doesn’t view itself as limited to service mesh and plans to follow market demand as it expands. The company emphasizes hiring diverse engineering talent (about 30% women) as it scales. Solo.io is an API infrastructure company that delivers application networking from the edge to service mesh, helping enterprises adopt, secure, and operate cloud-native technologies. Founded in 2017 by Idit Levine and based in Cambridge, MA, the company builds products across service mesh, API gateway, and WebAssembly for Envoy, Istio, and Gloo. Its 2020 product work included an open-sourced Service Mesh Hub, the industry-first Developer Portal for Istio, a federated multi-cluster API gateway management plane, and WebAssembly developer tooling and a module image specification. Solo.io also shipped Gloo API Gateway 1.5 with multi-cluster failover, security, and traffic control improvements, and enhanced Developer Portals for Gloo and Istio. Financially, the company raised $23M in a Series B that brought total funding to $37M. The company plans to use the funds for product and cloud-native community innovation in 2020, including new first-to-market offerings and an industry specification. Solo.io provides a suite of open-source and commercial tools to help enterprises adopt cloud-native technologies. Its open-source projects include the Gloo function gateway, the Sqoop GraphQL server, the SuperGloo service-mesh orchestration platform, a Kubernetes debugger, and unikernel tooling. The company’s first commercial product is Gloo Enterprise, an API/function gateway built on the Envoy proxy that routes requests to microservices, serverless platforms like AWS Lambda, and legacy monolithic applications while handling load balancing. Solo.io says Gloo can invoke AWS Lambda about 350ms faster than the AWS API Gateway and can reduce costs by limiting use of more expensive services. The enterprise edition adds audit controls, single sign-on, and advanced security features. The company plans to use its new funding to invest in product development for both enterprise and open-source tools and to grow sales, marketing, customer success, support, and education/evangelism efforts.
