Best CLM for multilingual contracts: Sirion’s 100+ language advantage

Global Contracts, Local Languages: The New CLM Imperative

Regulatory complexity has reached unprecedented levels in 2025. As companies navigate cross-border deals worth billions and manage supplier relationships across continents, a critical challenge emerges: most contract lifecycle management (CLM) systems deliver quality AI only on English contracts, leaving global enterprises vulnerable to costly mistakes in their multilingual agreements.

The stakes couldn’t be higher. Poor contract management costs companies 9% of annual revenues, and when language barriers compound this risk, the potential for revenue leakage, compliance failures, and missed obligations multiplies exponentially. Yet the average global website supports just 34 languages while enterprises need hundreds to truly operate globally.

Contract lifecycle management solutions are systems that automate the authoring, negotiation, execution, implementation, monitoring and renewal of B2B contracts. But when these systems stumble on non-English contracts, they transform from efficiency engines into liability generators. The solution? A CLM platform that treats every language with equal sophistication, turning language diversity from a risk factor into a competitive advantage.

Why Most CLMs Stumble Beyond English

The language limitations plaguing most CLM platforms stem from a fundamental architectural flaw: their AI engines are trained on 90% English content. This overwhelming bias creates systems that “think” in English even when processing other languages, leading to mistranslations that create real legal liability.

A Cornell University study revealed that large language models tend to “think” in English, even when generating text in other languages. This isn’t just a technical curiosity – it’s a business risk. When your CLM misinterprets a liability clause in a Japanese contract or fails to flag a deviation in a German service agreement, the consequences ripple through your entire operation.

The problem extends beyond simple translation errors. Many CLM vendors offer language preferences and claim multilingual support, with platforms like ContractPodAi allowing users to choose their language preferences and Agiloft supporting creation, management and negotiation in different languages. Yet these solutions often fall short when dealing with the nuances of legal language across cultures. Without culturally aware models, these systems struggle with context and miss critical deviations.

English Bias in Large Language Models

The data speaks volumes about this systemic bias. GPT-4 was trained on a staggering 90% English content, with only a fraction consisting of other languages. This predominance of English data biases LLMs toward English-centric thinking patterns and linguistic structures, creating a cascade of problems for global enterprises.

Stanford researchers found that 1.52 billion people who speak English benefit from advanced AI capabilities, while the world’s 97 million Vietnamese speakers and 1.5 million Nahuatl speakers experience significantly degraded performance. As one expert noted, “There’s been excellent research showing that many language models pick up values that match the language they’ve been trained on,” creating not just linguistic but cultural misalignments that can derail international deals.

Inside Sirion’s 100-Language AI Engine

Sirion’s approach to multilingual contract management represents a fundamental departure from the English-first architecture of traditional CLMs. Named a Leader in Gartner’s 2024 Magic Quadrant for CLM for the third consecutive year, the platform manages 7M+ contracts worth nearly $800B in 100+ languages.

The platform’s AI Extraction Agent processes up to a million documents daily, supporting over 100 languages with equal sophistication. This isn’t just translation – it’s true multilingual intelligence that understands the legal nuances, cultural contexts, and regulatory requirements unique to each language and jurisdiction.

What sets this system apart is its commitment to explainable AI. Every response is cited to precedent in your own contract data, ensuring transparency and trust. Your data remains isolated to your own environment, never sent to external large language models or used for training, addressing the security concerns that plague generic AI solutions.

Multilingual Data Extraction & Redlining

The platform’s redlining capabilities transform multilingual negotiation from a bottleneck into a competitive advantage. Users experience 60% faster contract redlining across all supported languages, with clear issue summaries and suggested redlines that respect linguistic and legal nuances.

The system doesn’t just translate – it truly understands. Users can review and redline contracts 80% faster, with the AI identifying three times more issues during redlining than manual review. This comprehensive analysis extends across all 100+ languages, ensuring that a supply agreement in Mandarin receives the same rigorous scrutiny as one in English.

Results: Faster Cycle Times, Lower Risk, Happier Teams

The business impact of true multilingual CLM capabilities extends far beyond translation accuracy. Organizations using Sirion report a 60% faster contract review cycle, translating directly into accelerated deal closure and reduced operational costs. When poor contract management typically costs companies 9% of annual revenues, the ability to manage multilingual contracts with precision becomes a significant competitive advantage.

The platform’s impact on negotiation efficiency is equally impressive, with 40% faster negotiation cycles across all languages. This acceleration doesn’t come at the cost of quality – instead, the AI identifies three times more issues during redlining than traditional methods, catching problems that human reviewers might miss in unfamiliar languages.

Spend Matters validates these results, noting that “While some CLM solutions have historical strengths in certain areas of contract management, Sirion is a true enterprise CLM solution applicable to buy side, sell side and other legal department use cases.” This versatility across use cases and languages positions the platform as the go-to solution for enterprises serious about global contract management.

How Sirion Stacks Up Against DocJuris & DocuSign CLM

While competitors have recognized the multilingual challenge, their solutions remain fundamentally limited. DocJuris allows users to upload contracts in any language and use playbooks written in any language, but this flexibility doesn’t translate into true understanding. Their interface can be translated for non-English speakers, yet the underlying AI still struggles with the nuances that make or break international deals.

DocuSign CLM has made strides in global operations, with Genuine Parts Company reporting that “Whether in Europe, APAC, the United States or Canada, we all speak the same language now when it comes to contracts.” However, this standardization often means forcing all contracts into English-first workflows rather than truly supporting native language operations.

The key differentiator lies in depth versus breadth. While DocuSign offers 10+ use cases across 5 departments and DocJuris emphasizes security with SOC 2 Type II certification, neither matches the combination of 100+ language support with AI that actually understands each language’s legal and cultural context. As Spend Matters notes, Sirion “augments its strong core CLM functionality with unique capabilities for post-signature contract management including obligation and service level management,” capabilities that become even more critical when managing contracts across language barriers.

Best Practices for Rolling Out a Multilingual CLM

Implementing a multilingual CLM requires more than selecting the right technology – it demands a comprehensive change management strategy. Andrew Ng’s AI Transformation Playbook offers a valuable framework for introducing AI in ways that minimize risk and maximize organizational acceptance, particularly crucial when dealing with the complexity of multilingual operations.

Start with pilot projects that demonstrate tangible benefits. As change management experts emphasize, “A structured change management process reduces uncertainty, strengthens adoption, and improves execution.” Choose high-visibility contracts in your most critical languages to showcase the platform’s capabilities and build organizational confidence.

The human element remains paramount. With 97% of accounting firms saying they use tech inefficiently, proper training becomes the difference between transformation and expensive failure. The Prosci ADKAR model outlines fundamental elements including awareness, desire, knowledge, ability, and reinforcement – each requiring special attention in a multilingual context.

Governance structures must evolve to match your new capabilities. Establish clear protocols for which languages require native review versus AI-assisted review. Define escalation paths for high-risk multilingual contracts. Most importantly, create feedback loops that allow your legal teams in different regions to share insights and continuously improve the system’s performance.

Data quality becomes even more critical in multilingual environments. Pilot projects help transform abstract AI potential into tangible benefits, but only if the underlying contract data is clean and properly tagged. Invest time in standardizing contract templates across languages while preserving necessary local variations.

What’s Next: Agentic AI and 300-Language CLM

The future of multilingual contract management is being shaped by the convergence of agentic AI and expanding language capabilities. Forrester predicts that “As generative AI evolves into agentic AI, automation becomes more sophisticated, and emerging technologies shift to large-scale deployment, firms will no longer be experimenting with AI by the end of 2025 – they will be racing to keep up with AI’s acceleration.”

This evolution promises CLM systems that don’t just process multiple languages but actively adapt to linguistic and cultural nuances in real-time. Gartner forecasts that by 2029, agentic AI will autonomously resolve 80% of common issues without human intervention, a capability that could transform how global enterprises manage cross-border contracts.

The integration of RAG (Retrieval-Augmented Generation) with AI agents is creating what experts call Agentic RAG, where AI systems possess “the capability to act autonomously to complete tasks.” For contract management, this means CLM platforms that can independently identify jurisdiction-specific requirements, suggest culturally appropriate negotiation strategies, and even predict potential disputes based on linguistic patterns in contract language.

Turn Language Risk Into Commercial Advantage

The multilingual contract challenge isn’t going away – if anything, it’s intensifying as global trade becomes more complex and regulated. The question isn’t whether you need multilingual CLM capabilities, but whether you’ll implement them before language barriers cost you deals, compliance failures, or competitive position.

Sirion’s approach – managing contracts worth nearly $800B in 100+ languages with explainable AI – demonstrates that language diversity can become a strategic asset rather than an operational burden. By unifying legal, procurement, sales, and operations teams around a single source of contract truth that works equally well in any language, organizations can finally operate as truly global enterprises.

The path forward is clear: embrace comprehensive multilingual capabilities now, or risk being left behind as competitors leverage language advantage to win deals and enter new markets. With Sirion’s proven platform delivering 60% faster contract review cycles and identifying three times more issues during redlining across all languages, the choice becomes not whether to adopt multilingual CLM, but how quickly you can transform language risk into commercial advantage.

Explore how Sirion’s multilingual capabilities can transform your global legal operations and turn contract language diversity into your competitive edge.
