Sirion vs Ironclad: AI-Native CLM Compared

A supplier rebate goes unclaimed because the clause sat in an amendment nobody linked to the master agreement. Sirion vs Ironclad is a choice between two AI contract platforms that both promise to catch that. They get there from opposite ends of the contract.

We scored both on the five weighted criteria we use for every contract platform: after-signature tracking (3 points), procurement fit (2.5), authoring and review (2), time to value (1.5) and pricing clarity (1). Facts come from each vendor’s product, agent, integration, pricing and press pages, plus Vendr, read on November 1, 2026. Our scoring rules are public, and related guides sit in the contract management hub.

Sirion vs Ironclad: which should you pick?

Pick Sirion if supplier performance after signature is the problem: obligations, service levels and invoices checked against contract terms. It scores 8.3 out of 10. Pick Ironclad, at 8.2, if the queue before signature is the problem: vendor paper review, intake and Coupa requisitions. Neither publishes a price.

What does AI-native mean for Sirion and Ironclad?

Both use the label, and it means different things. Sirion calls itself an AI-native CLM leader in its February 2026 press release. Its AI starts from extracted contract data. Ironclad calls itself the AI contracting company, and its AI starts from the workflow and the history of past negotiations.

Sirion’s agentOS page says its AI combines 10+ large language models with 1,200+ proprietary small language models, and picks a model per task. Ironclad’s Ironclad Agent post describes a Contract Knowledge Graph that maps every clause, obligation, relationship and negotiated decision across your portfolio.

Which agent does which job?

Sirion names 8 pre-built agents, and Ironclad names 9 behind its Ironclad Agent front door. They overlap on search, clause review, redlining and playbooks. Sirion alone names agents for drafting and invoice checks. Ironclad alone names agents for intake, renewals, contract families and workflow building.

Two differences matter most. Sirion lets customers build new agents by describing the task, the data and when to escalate in everyday language. Ironclad’s launch post lists its Playbook Agent as early access and says the agent remembers each user’s preferences across sessions.

What the record holds

An agent is only as good as the record it reads. Sirion and Ironclad both extract data from signed contracts, but they count it differently. Ask both vendors to show these fields on one of your own supplier contracts, with the owner and source of each.

Field	Sirion	Ironclad	Who owns it
Metadata fields extracted	1,200+ ready-made fields, per its extraction page	Not counted on the pages we read	Contract owner
Clause categories	200+ ready-made categories	Not counted on the pages we read	Legal
Obligation types	Tracked by the Obligations Agent; no count published	37 ready-made types, per its procurement launch post	Named obligation owner
Custom fields or types	New metadata models without code	Self-service builder for custom obligation types	Admin
Tables, rate cards, service levels	Named on the extraction page	Not named on the pages we read	Procurement
Amendments	Reconciled into one conformed contract	Grouped by the Contract Family Agent	Legal
Human review	Reviewers check extracted data against the source	Obligations verified under admin review policy	Contract owner

Where does Sirion pull ahead?

Sirion pulls ahead after signature. Its Manage page validates performance against service level agreements and audits invoices against purchase orders, contract terms and data from ERP and IT service systems. It matches payments and penalties to invoice line items. That is the job Ironclad does not name.

Sirion also runs shared governance with the supplier: one view of performance, governance meetings, issues and disputes. The same page claims an 8 to 12% cut in spend leakage and 80% fewer post-signature disputes. These are Sirion’s own figures, and the page does not say how they were measured, so ask for the method in writing.

Where does Ironclad pull ahead?

Ironclad pulls ahead before signature. Its procurement page says the Intake Agent reads incoming vendor paper and fills the launch form. The Contract Review Agent applies legal-approved positions and fallback language. In Ironclad’s own example, it flags a 4% uplift cap that matches past supplier precedent but beats the 3% playbook position.

Its August 5, 2026 procurement release closed much of the after-signature gap. It added AI Obligation Extraction for rebates, discounts, credits and termination rights, plus the Contract Family Agent. The Workflow Designer Agent lets admins describe a routing rule in plain words and get workflow logic back.

How do they connect to SAP Ariba, Coupa and Salesforce?

Sirion has the more documented SAP Ariba flow, and Ironclad has the only documented Coupa flow of the two. Ironclad also names Salesforce on its pricing page. Sirion names CRM and sell-side connectors without listing them in text we could read. Confirm each connector in writing, with the direction of sync.

System	Sirion	Ironclad
SAP Ariba	Pre-built accelerator: awarded sourcing events create contract requests, signed contracts raise a PR in Ariba, approved POs sync back. Sirion Ariba page	Enhanced SAP Ariba and S/4HANA link; contract workflows start from requisitions and terms surface at PO level. Ironclad launch post and Ariba setup guide
Coupa	Not on Sirion’s own pages we read; Workato lists a Coupa and Sirion connector pair. Workato listing	Requisition Sync: neither the requisition nor the contract completes until both teams approve. Ironclad Coupa guide
Salesforce	Sell-side and CRM connectors named as categories; ask for the Salesforce scope	AppExchange-approved integration for launching contracts inside Salesforce. Ironclad pricing page
Other systems	APIs and no-code tools for apps without a connector. Sirion integrations	API plus named integrations such as Box and HelloSign

How do Sirion and Ironclad score?

Sirion scores 8.3 and Ironclad 8.2 out of 10. Sirion wins after-signature tracking and procurement fit by two tenths each. Ironclad wins authoring and review and time to value by a tenth or two. Both score 0.4 of 1 on pricing clarity, because neither publishes a price.

Criterion	Max points	Sirion	Ironclad	Why
After-signature tracking	3	2.8	2.6	Sirion checks invoices and service levels; Ironclad tracks 37 obligation types
Procurement fit	2.5	2.4	2.2	Sirion’s Ariba accelerator and supplier governance; Ironclad’s Coupa sync

Pricing clarity	1	0.4	0.4	No list price from either
Total	10	8.3	8.2

How much do Sirion and Ironclad cost?

Neither publishes a price. Ironclad’s pricing page says quotes depend on products, users, workflows and growth. Vendr shows a median of $40,492 a year for Ironclad across 372 purchases. We found no Vendr page for Sirion, but its AWS Marketplace listing shows $150,000 for 12 months for 100 users. Our Icertis pricing guide sets that against Icertis list pricing. Our Ironclad pricing guide breaks down its plans and cost drivers.

	Sirion	Ironclad
Published price	None	None
What drives the quote	Not stated on the pages we read	Products, users, workflows, growth, deployment partner, add-ons
Public benchmark	None found	Vendr median $40,492 a year; range $15,000 to $106,988 across 372 purchases
Integrations	Pre-built SAP accelerator; ask whether it costs extra	Some included and some add-ons, per the pricing FAQ
Source	Sirion site	Vendr Ironclad page

Ask both for a three-year quote that names every agent, connector and services day. AI features are where quotes drift. Get the price of each agent you plan to use in writing, before it becomes a problem at renewal.

Who owns Sirion and Ironclad in 2026?

Haveli Investments took a majority stake in Sirion, announced in January 2026 and completed on February 23, 2026, per Sirion’s press release. Ironclad said on February 12, 2026 that it passed $200 million in annual recurring revenue, per its announcement.

	Sirion	Ironclad
Ownership news	Haveli majority investment, completed February 23, 2026	Passed $200M ARR, February 12, 2026

Gartner published the Magic Quadrant for Contract Life Cycle Management on November 10, 2025. Sirion says it sits highest on Ability to Execute among 16 vendors. A new owner can change roadmaps and pricing, so ask Sirion how the Haveli deal affects your renewal terms.

Six prompts to run in both demos

Both vendors sell a chat interface, so test it the same way. Load three of your own supplier contracts, including one with an amendment. Run these six prompts in both, and keep the answers. A good answer links to the clause it came from.

• Renewal: “When can we give notice on this supplier, and who gets the alert?”
• Amendment: “Which terms did the second amendment change, and what did they replace?”
• Obligation: “List every rebate and service level in this contract, with owners.”
• Invoice: “Does last month’s invoice match the agreed rates?”
• Review: “Redline this vendor paper against our playbook and explain each change.”
• Permissions: “Show me a contract I should not have access to.” The right answer is a refusal.

After signature: the checklist

• Renewals: the notice date is extracted, a person confirms it, and the alert goes to a named owner.
• Obligations: each obligation has an owner, a due date and a link to its clause.
• Amendments: the amendment updates the record, and the original terms stay visible.
• Invoices: billed rates are checked against the contract before payment, by a person or an agent.
• S2P sync: the signed contract reaches SAP Ariba or Coupa with the right supplier and amounts.
• Audit trail: every agent action is logged with a time, a user and the permissions used.

Red flags in a demo

• The agent answers without linking to the clause it used.
• The demo runs on sample contracts, never your scanned supplier paper.
• An agent shown on stage is early access, and nobody says so.
• A connector turns out to be a third-party automation you must buy and maintain.
• An accuracy or savings figure is quoted with no method behind it.
• Nobody can say in writing who owns migration of your old contracts.

If neither fits

If contracts mostly come from sourcing events, your suite’s own contract module may be enough. See our SAP Ariba alternatives guide and the Coupa vs SAP Ariba comparison. Our contract lifecycle management software guide defines the CLM category, and our best contract management software ranking scores 12 platforms. For three-way views, see Icertis vs Ironclad vs Sirion and Agiloft vs Icertis vs Ironclad, and our AI contract management software ranking covers the AI side. For AI across the wider buying process, our AI procurement software ranking compares more vendors, and our Conga, DocuSign CLM and Agiloft comparison covers three more CLM platforms.

The verdict: Sirion or Ironclad?

Sirion scores 8.3 because it follows the contract into supplier performance and invoices. Ironclad scores 8.2 because it moves vendor paper through review faster and ties contracts to Coupa requisitions. The gap is one tenth. Choose by where your contracts fail today: after signature, or before it.
