What Sandstone does
Sandstone is an AI-native legal relationship management (LRM) platform built for in-house corporate legal teams. Operating as Glaze AI, Inc. (dba Sandstone) with operational headquarters in Brooklyn, NY, and engineering presence in Cape Town, the company positions its product as a system of intelligence and orchestration layer for general counsel, legal operations, and contract management functions at mid-market and enterprise organizations. Named customers span e-commerce, fintech, manufacturing, proptech, and edtech (Wayfair, MasterClass, Hypertherm, Ocrolus, Crexi, Middesk among 25+ logos).
The platform is organized around five integrated modules: Repository & Knowledge Management, Intake & Triage, Agentic Workflows, Context Map, and Reporting. Its central technical artifact is a proprietary Context Map — a structured knowledge graph that links contracts, clauses, parties, policies, and prior decisions, enabling agentic multi-step execution, sentence-level risk detection, and playbook-driven negotiation. The product integrates with 50+ native systems across CLM, ERP, CRM, and document management categories, is SOC 2 certified, and is delivered via a Forward Deployed Engineer model alongside a sales-led, demo-driven motion with quote-based subscription pricing that is not publicly disclosed. Customer acquisition is anchored on named case studies at Middesk, MasterClass, Crexi, Ocrolus, and Hypertherm.
The company was founded in 2025 and launched publicly in January 2026. It has raised approximately $40M in total disclosed venture funding from Sequoia (seed) and Lightspeed (Series A); AlleyWatch cites up to $49.6M including secondary or unannounced tranches. Leadership includes CEO Nick Fleisher (ex-McKinsey legal tech), COO Jarryd Strydom, CTO Liam Germain, and President/CSO/CLO Jessica Nguyen (ex-DocuSign Deputy General Counsel), joined March 2026. Strategic partners include LegalEng Consulting Group and advisor Mary O'Carroll. The company competes within a $2.4B+ legal tech funding market recorded in the first nine months of 2025. No revenue or ARR has been publicly disclosed.

Sandstone product offering
Product offeringCore offering
Sandstone provides an AI-native Legal Relationship Management platform for in-house legal departments. The platform unifies legal intake, contract management, workflow automation, contextual research, and reporting through five integrated modules (Repository & Knowledge Management, Intake & Triage, Agentic Workflows, Context Map, and Reporting & Insights), supported by 50+ native integrations with email, messaging, project management, CLM, and document systems. It is sold as a quote-based subscription with sales-led deployment to Fortune 500 and growth-stage companies.
Product overview
Sandstone offers a single unified platform — the "Legal Relationship Management" platform — that coordinates the day-to-day work of in-house legal departments. The platform is built as a platform-plus-modules architecture with five core modules: (1) Repository & Knowledge Management (CLM+), which stores documents and links them to counterparties, people, and past decisions; (2) Intake & Triage, a conversational intake layer that captures requests from 50+ business tools and auto-routes them; (3) Agentic Workflows, which runs the full lifecycle from intake to redline, draft, review, and e-signature; (4) Context Map, which automatically surfaces stakeholder, deal, and risk context for every request and is queryable in natural language; and (5) Reporting & Insights, which provides custom metrics, benchmark comparisons, and prompt-based reporting. The modules are tightly integrated — Intake feeds Triage, Triage routes into Workflows, Workflows and Repository are powered by the Context Map, and Reporting aggregates signals from all of them.

- Agentic Workflows Workflow engine that runs the full lifecycle from intake to execution — triage, contextual research across systems, playbook-aligned redlining, replying to comments, drafting from best practices, sending for e-signature, and storing memory for future deals.
- Context Map (Legal Relationship Management) Automatically surfaces stakeholder history, past lawsuits, financial agreements, active workflows, prior decisions, and sentence-level risk for each incoming request; queryable in natural language from Sandstone, Slack, Teams, or Claude.

Sandstone competitors and assessment
Company assessmentDirect peers
- Harvey: Harvey is an AI legal platform used by elite law firms and in-house legal teams for contract analysis, drafting, and research. It is the most direct competitor to Sandstone in the AI-native legal workflow category, sharing Fortune 500 buyers, agentic workflows, and playbook-style use cases.
- Evisort: Evisort is an AI-powered contract management and analytics platform used by enterprise legal and procurement teams. Its focus on automated contract intelligence, risk flagging, and obligation tracking overlaps directly with Sandstone's Repository & Knowledge Management and sentence-level risk detection modules.
- Legora: Legora is an AI legal assistant used by lawyers for drafting, review, and research, with growing traction among in-house teams. It competes head-to-head with Sandstone and Harvey in the AI-native legal assistant category and is a credible alternative in the European and US markets.
- Spellbook: Spellbook is an AI copilot for lawyers focused on contract drafting and review using LLMs trained on legal data. It targets in-house counsel and law firms with similar playbook-style drafting and redlining workflows to Sandstone's Agentic Workflows module.
- LinkSquares: LinkSquares provides AI-driven contract lifecycle management and analytics for in-house legal departments. It competes for the same GC, legal ops, and procurement buyer personas as Sandstone, with overlapping intake, repository, and analytics capabilities.
- Ironclad: Ironclad is a contract lifecycle management (CLM) platform with workflow automation used by in-house legal teams including MasterClass (a public Sandstone customer). Sandstone explicitly ingests Ironclad records and consolidates Ironclad-sourced NDAs into a single queue, positioning itself as an AI layer on top of CLMs rather than a CLM replacement.
Broad incumbents
- Luminance: Luminance is an AI platform for contract review and analysis used by enterprises and law firms globally, with strong traction in highly regulated industries. It overlaps with Sandstone's AI redlining and deviation detection but operates as a broader AI legal suite rather than a relationship-first platform.
- Onit: Onit is an established enterprise legal management platform encompassing CLM (via ContractPodAi), matter management, and spend management for in-house legal departments. It serves as a broad incumbent alternative to Sandstone's focused LRM offering, often with deeper procurement integration.
Emerging players
- Hebbia: Hebbia is an AI knowledge worker platform that ingests and analyzes large document sets for professional services firms, including legal and financial services. Its Matrix product and agent-driven document analysis overlap with Sandstone's agentic contract workflows and enterprise document understanding pipelines.
- Glean: Glean is an AI enterprise search and knowledge platform that indexes documents, conversations, and tickets across SaaS tools, similar to Sandstone's Context Map. While Glean targets enterprise-wide knowledge rather than legal specifically, its cross-system retrieval approach and large enterprise install base make it a credible adjacent threat to legal knowledge workflows.
