Sirion pricing
Sirion does not publish prices. G2 lists the entry price as Contact Us on an Enterprise tier, and the vendor shows no plans, seat rate, annual discount or add-on list. What drives a quote is not stated either, so assume it depends on contract volume, modules and rollout scope. A competitor's article advises getting the per-seat quote and the renewal cap in writing, which is sensible whichever vendor you choose. Billing and renewal terms are not published, and the early 2026 ownership change is a reason to ask about price protection at renewal.

What Sirion really costs
Sirion publishes no price list, so the real cost depends on the quote. Use the questions below to turn a sales conversation into a number you can compare.
Questions to ask about price
- What is the price per user or per unit, and what is the pricing basis (seats, employees, usage)?
- Is there a minimum number of seats or a minimum annual spend?
- What is the discount for annual billing, and can we start monthly?
- Which features we need sit in add-ons or a higher plan, and what do they cost?
- How much can the price rise at renewal, and is the increase capped in the contract?
- Are there one-time costs for implementation, onboarding or data migration?
Is Sirion worth the price?
Sirion is worth a quote request for large enterprises with complex, high-volume contract portfolios that need post-signature obligation tracking and multi-language analytics across 100+ languages. It gets expensive and awkward for small and mid-size teams, since it is an enterprise tier with quote-only pricing. Reviewers also flag configuration complexity, and third parties report long implementations, so factor in services time alongside licence cost.
Worth it if
- Large enterprises with complex, high-volume contract portfolios.
- Teams that need multi-language contract analytics (100+ languages)
Look elsewhere if
- Small and mid-size teams (enterprise tier, quote only)
- Buyers who need a fast rollout; third parties report long implementations.
Pricing details most reviews leave out
- Sirion's AI base came partly from the June 2024 acquisition of Eigen Technologies.
- Haveli Investments took a majority stake in early 2026, a change of ownership relevant for contract renewals.
- Gartner Peer Insights shows 4.9 from 261 ratings for the Agentic CLM platform, but the page mixes snapshots.
- Third-party Spellbook claims implementations can exceed six months; competitor source, treat with caution.
- Sirion's compliance page references ISO 27001:2022; SOC 2 Type II is described but not clearly confirmed in what we could read.
- G2 product page shows 4.5 and comparison page 4.6, both from 65 reviews.
Our verdict on Sirion
Sirion, formerly SirionLabs, is an enterprise contract lifecycle management platform with no public pricing.

Majority investment from Haveli Investments was announced in January 2026 and closed in February 2026. G2 shows 4.5 from 65 reviews.
Expect a quote built for large, high-volume contract portfolios. Reviewers praise the AskSirion AI features and reporting, and they complain about a steep learning curve, complex configuration and a premium price. Small and mid-size teams are not the target buyer, and the process starts with a sales conversation.
