Side-by-side comparison

Dimension	Vallor	Sirion
Primary model	An AI coworker that reads contracts, watches systems, answers questions, and triggers follow-up work. An intelligence layer across existing systems, not a new operating system.	An AI-native enterprise CLM platform.
Implementation	First value in minutes from existing repositories and integrations. Win	Often an enterprise deployment with data migration and process alignment. Ask for a live proof using 50 of your own contracts.
AI depth	Contract-specific reasoning, citations, obligation execution, review support, and benchmarking from portfolio data.	AI-native CLM with contract data, analytics, and automation. Ask whether AI can act on business context, not only summarize documents.
Best fit	Procurement, legal, finance, and sales teams that need fast visibility into active and legacy contracts.	Large enterprises with complex supplier and customer contracting programs. Map the platform to the team that owns value leakage.
Commercial posture	Designed to cost a fraction of one FTE and avoid a large implementation services motion. Win	Usually enterprise quote-based. Confirm license, services, storage, AI usage, and integration costs. Compare total cost, not seat price.

Migration path

Sirion holds contracts, metadata, and obligations in its enterprise data model, with an extraction agent that covers 1,200+ fields. Export a representative contract set and its key metadata from Sirion, then connect ERP, AP, CRM, email, and shared drives through Vallor's connectors.

Most teams keep Sirion running during the transition.
