About Sandstone

Sandstone provides an AI-native operating system designed to convert institutional knowledge into agentic workflows for in-house legal teams. The company was co-founded by CEO Nick Fleisher, a former corporate legal consultant at McKinsey where he led the legal technology practice, and Jarryd Strydom, a lawyer with in-house counsel experience. The idea for the company originated from the founders' shared frustration with the inefficiencies faced by in-house legal departments, such as scattered information and repetitive tasks.

The platform serves as a centralized intelligence layer that integrates with existing business systems like Slack, Salesforce, and email to automate legal request intake, triage, and workflows. It employs AI agents that continuously learn from every interaction to build dynamic playbooks, allowing legal teams to manage and execute tasks from intake to completion. Key features include automated document management, intelligent contract review, and workflow optimization tools that help legal departments focus on higher-value strategic work. The system is designed to create 'context-in-motion' by connecting each workflow to its underlying business context, ensuring expertise is shared and applied consistently.

Sandstone caters to legal departments in companies ranging from fast-growing startups to global F500 enterprises across various industries, including software, finance, and manufacturing. The company's business model is based on providing this technology to streamline operations and reduce the administrative burden on legal professionals. In January 2026, the company announced a $10 million Seed funding round led by Sequoia Capital, with participation from numerous general counsels and legal sector experts, signaling strong investor confidence in its approach to solving long-standing issues in the legal tech space.
