About Sandstone
Sandstone is purpose built by legal engineers and GCs who understand that efficiency is not just about speed, it is about context. The company is backed by Sequoia, Lightspeed, and F500 GCs and is headquartered in New York.
What is Sandstone
Sandstone grew out of a shared frustration. Legal has relationships with every part of the business, so the context that makes the work possible gets trapped in separate tools and siloed workflows. Teams keep answering the same questions, rewriting the same clauses, and spending their time on process instead of progress. Sandstone connects every company, person, document, and relationship related to legal work into a single connected system of record, then uses it to route, draft, and execute that work with the same context a seasoned lawyer would bring, directly in the tools teams already use. Building an AI-native legal department is a structural shift, not a tooling decision. That only works if the people building it have lived the problem: former GCs, legal ops leaders, and engineers who have spent their careers inside these workflows.

Why Sandstone exists
Sandstone was born out of the frustration of in-house legal departments who spend more time on process than progress because context is scattered across email, chat, contracts, and point tools. The platform creates a legal control tower that connects every workflow to the business context behind it.
