How Sandstone Grew 40x in 147 Days with Vercel

Legal tech startup Sandstone built a platform that automates the manual process of legal teams gathering data. They automatically extract context from various systems such as Salesforce, email, and messaging tools, providing an environment where lawyers can focus on their work immediately.

Sandstone achieved 40x revenue growth in less than 6 months after launch. Behind this explosive growth, Vercel's infrastructure played a key role.

The main factors that enabled this growth are as follows:

• Preview Deployments: Providing a fast deployment environment that earns the trust of enterprise customers
• AI SDK: A flexible AI layer that enables agentic workflows to be implemented in minutes
• Secure Compute: A secure computing environment that allows security issues to be resolved immediately

In particular, Vercel's features maximized development speed. A customer request that came in on a Sunday could be reflected in production in 5 minutes, and by using Preview branches and inline comment features, feedback from the marketing team was automatically connected to engineering tickets (Linear issues), boosting collaboration efficiency.

Also, they use Vercel Flags to control features without deployment, and efficiently manage a Monorepo containing 7 or more applications. Sandstone is evolving beyond simple classification into a complex AI agent workflow that searches thousands of contracts, detects risk factors, and sends alerts to Slack.
