Sirion
Agentic AI contract lifecycle management for the enterprise
About Sirion
Sirion (formerly SirionLabs) is an enterprise contract lifecycle management (CLM) platform built around AI agents and a conversational interface called AskSirion. It covers the full contract lifecycle, from extracting and organizing legacy contracts to drafting, negotiation, obligation tracking, and invoice reconciliation. Gartner named it a Leader in its 2025 Magic Quadrant for Contract Life Cycle Management.
Pros & Cons
Pros
- Covers post-signature work such as obligations, service levels, and invoice reconciliation, not only drafting and approval
- AI answers and redlines include source links and explanations, which makes them easier to verify
- Strong analyst standing, including Leader in the 2025 Gartner Magic Quadrant for CLM
- Reviewers on G2 and Gartner Peer Insights rate customer support and partnership highly
- Industry-specific solutions for financial services, insurance, healthcare, pharma, telecom, and IT services
Cons
- No published pricing; every deal goes through a sales demo and custom quote
- Built for large enterprises, so it is heavy for small legal or procurement teams
- Reviewers report setup friction and that reporting and admin settings for complex hierarchies need tuning
- Some users report mixed experiences after platform upgrades

Describe a task in plain language and AskSirion picks the right agents, runs them, and explains the result with source links.
AI-built contract repository
Point the extraction agents at your contract sources and they extract, normalize, and organize agreements into a structured, access-controlled repository.
Contract search and portfolio Q&A
Ask questions about a single contract or the whole repository, such as risk exposure or spend patterns, and get answers linked to the source clauses.
AI drafting and playbooks
Generate NDAs, service agreements, and MSAs from your templates, and build playbooks automatically from precedent agreements and policies.
Negotiation and redlining in Word
Issue Detection and Redline agents flag clause-level deviations and propose policy-backed edits, with counterparty insights inside Microsoft Word.
Obligation and performance management
Track obligations, renewals, and service levels after signature, with alerts before breaches or missed commitments.
Invoice reconciliation
The Invoice agent checks invoices against contract terms and flags mismatches so payments match the agreed value.
