How Rillet ships 3× faster with AI agents on Vercel
Rillet, an AI-native ERP platform, accelerated software delivery threefold by deploying AI agents on Vercel, reducing customer request fulfillment from days to hours.
Rillet, an AI-native enterprise resource planning platform, uses AI agents to perform accounting tasks within a real-time general ledger, enabling customers to move toward zero-day financial closes. The company’s two-person frontend team, led by Anthony Liang, deploys these agents using eve, Vercel’s open-source agent framework, to automate internal workflows such as shipping customer fixes and reviewing code. Agents are built with instructions and tools consolidated in a single directory, allowing non-technical staff to configure behavior via markdown while developers manage TypeScript-based tools. Deployments are managed within Rillet’s Vercel organization, ensuring consistency and scalability across the company’s agent ecosystem.
Rillet leverages Vercel Connect to grant agents access to Slack and Linear through reusable, short-lived tokens that expire automatically, reducing credential management overhead. The team built a Slack bot that processes tickets and opens pull requests, while other agents handle incident analysis and Linear board management. Shared conventions in eve simplify reuse, enabling non-engineering teams like customer success to initiate changes directly through a Chrome extension that captures context and triggers agent-driven development workflows.
Customer requests are now fulfilled within two hours via Rillet’s in-house agent, Nebula, compared to prior cycles measured in days or weeks. Agents test changes in sandboxed browsers and attach screenshots as proof, while Anthony Liang reviews and merges pull requests, with agents resuming sessions to address feedback. The company reports shipping more in recent weeks than in the first half of 2026, tripling its deployment rate over the prior three months.
AI Gateway consolidates model provider access, allowing agents to route requests to Anthropic and OpenAI through a single integration without separate configurations. Usage tracking within AI Gateway helps Anthony Liang monitor spending and model performance, while Enterprise Managed Users centralizes Vercel account access under Rillet’s identity provider, replacing personal accounts with company-managed sign-ins managed via Google Workspace and directory sync.
