Serverless Inc.
Serverless Inc. is a San Francisco software company that builds the Serverless Framework, one of the most widely used open-source tools for deploying applications to AWS Lambda and other cloud functions. Founded in 2015 by Austen Collins, it turned a solo open-source project called JAWS into a de facto standard for infrastructure-as-code in the function-as-a-service era, then layered commercial products - a dashboard, observability, and a subscription license - on top for larger teams.
Traefik Labs
Traefik Labs builds the cloud-native networking layer that sits between your users and your services. Its flagship open-source Traefik Proxy - downloaded more than 3 billion times - auto-discovers containers and routes traffic without hand-written config, and its commercial Traefik Hub extends that into a unified 'Triple Gate' platform covering API, AI, and MCP traffic. Founded in France in 2016 and now headquartered in San Francisco, the company's stated goal is to make networking boring: reliable enough that developers stop thinking about it.
ngrok
ngrok is developer infrastructure that puts any app, API, or AI model online with a single command. What began in 2013 as one engineer's weekend project to learn Go is now a unified ingress platform - reverse proxy, firewall, API gateway, and global load balancer rolled into one - used by more than 5 million developers and trusted by companies like GitHub, Twilio, Zoom, and HashiCorp.
Kong Inc.
Kong Inc. builds the connectivity fabric for APIs, microservices, and now AI traffic. Its open-source gateway sits in front of billions of requests at companies like Cargill, SkyScanner, GE, and Sky. In 2024 it raised a $175M Series E at a $2B valuation, sharpened its pitch as 'the AI connectivity company,' and shipped an AI Gateway that brokers calls to LLMs the same way Kong has long brokered calls to REST APIs.
