How Waldium made a blog platform work for humans and AI alike
By Steven Van ·
A two-person startup serves 500+ customer blogs and their AI-agent MCP endpoints from one Vercel deployment, cutting infrastructure cost by 45%.
Vercel's Routing Middleware is the piece behind a Waldium case study out this week. Waldium is a two-person, YC-backed startup that runs an agentic CMS: it automates a customer's blog research and writing, and gives every customer blog its own MCP server endpoint so AI agents can query it directly. All of it, more than 500 customer blogs, runs from a single Next.js deployment rather than one deployment per customer.
New customers get a live MCP endpoint in under five minutes, and AI query responses come back in under 50ms globally. One customer generated more than 1,000 posts in a single month, cutting research time from weeks to hours. Running everything on one deployment instead of per-customer deployments cut Waldium's infrastructure cost by 45%. Co-founder Amrutha Gujjar said the aim was to keep infrastructure from getting in the way: "I was never stuck on the part I was excited to build. It was always the infrastructure friction around it."
