The global legal industry, long considered resistant to digital disruption, is on the cusp of a transformation. A&O Shearman’s latest venture—developing and deploying agentic AI agents in collaboration with Harvey—is not merely a tech upgrade; it’s the opening chapter of a redefined legal practice. These agentic tools are being rolled out internally, sold to clients, and even offered to rival law firms, all while aiming to accelerate multi-step legal workflows without compromising legal integrity or accuracy.
By fusing A&O Shearman’s elite legal acumen with Harvey’s leading AI infrastructure, the firms are pioneering a new legal operations model—one where intelligent agents autonomously manage complex, multi-layered legal tasks across domains like antitrust, cybersecurity, fund formation, and loan review. And notably, they’re doing this in real commercial terms: through revenue sharing, client subscriptions, and usage-based monetization.
This article offers an in-depth analysis of the deployment of agentic AI in the legal domain, its commercial implications, technical framework, and future outlook—backed by structured data, expert quotes, and authoritative insights.
The Rise of Agentic AI: Beyond Automation
Traditional legal tech has focused on digitization and workflow automation. Agentic AI, however, represents a substantial leap. Unlike narrow-task AI tools that follow strict if-then logic, agentic AI mimics human reasoning, autonomy, and adaptability—particularly important for nuanced legal workflows.
At its core, agentic AI embodies:
Multi-step reasoning
Interdependent task execution
Transparent audit trails
Matter-specific contextual understanding
These agents are not just chatbots; they are intelligent collaborators capable of interpreting case-specific documents, conducting detailed regulatory research, synthesizing insights, and even generating deliverables with minimal oversight.
“There has been a lot of hype, but these agents are the first concrete legal use-cases of agentic AI within a multinational law firm—and therefore within much of the commercial landscape.”— David Wakeling, Global Head of AI Advisory, A&O Shearman
Applications: Where Legal Expertise Meets Agentic Intelligence
The initial wave of A&O Shearman’s AI agents target high-value, high-complexity areas of law:
Domain | Legal Function | Agentic AI Capability |
Antitrust | Filing Analysis | Extracts filing data, cross-references global regulatory requirements, flags compliance risks |
Cybersecurity | Regulatory Analysis | Monitors changing policies, evaluates incident reports, auto-generates compliance strategies |
Fund Formation | Structuring & Compliance | Maps fund hierarchies, reviews LP agreements, assesses jurisdictional constraints |
Loan Review | Leveraged Finance | Reviews documentation, extracts covenants, performs comparative analysis |
These are areas where legacy tools fall short. The agents go beyond keyword search—they ingest entire documents, reason across multiple inputs, and output structured, actionable insights.
“Loan documentation for leveraged finance transactions is highly complex and bespoke… We’ve created an agent that can extract data and perform comparative analysis across portfolios—quickly, reliably, and efficiently.”— Filippo Crosara, Partner, A&O Shearman
Business Model Innovation: AI as a Revenue Stream
For the first time, A&O Shearman is not just using AI to improve internal efficiency—they are selling it. The tools will be offered via subscription and usage-based fees to corporations, financial services, and other law firms.
This is significant for several reasons:
Software Revenue Sharing: A&O Shearman will share revenue from the commercial use of the software—marking a departure from traditional billable hour models.
Legal IP as Product: By embedding its legal expertise into agentic systems, the firm is effectively monetizing its intellectual capital.
Market Leadership: Offering these tools to peer firms is a bold strategy that positions A&O Shearman as a leader in legal innovation.
“For decades, the legal industry has relied on the same structure… Together with A&O Shearman, Harvey is building agentic workflows that save tremendous amounts of time without sacrificing accuracy and trust.”— Winston Weinberg, CEO, Harvey
Technical Architecture: What Makes Agentic AI Work
While specifics are proprietary, the architecture likely includes:
Large Language Models (LLMs) for context understanding and document synthesis
Multi-agent collaboration frameworks for sequential task execution
Rule-based compliance engines for jurisdictional requirements
Custom datasets curated from A&O Shearman’s internal legal IP
The combination allows the agents to ingest unstructured legal texts, identify actionable items, synthesize intermediate findings, and construct final work products—often faster than a team of junior lawyers.
Estimated Performance Gains:
Task | Traditional Time | Agentic AI Time | Time Saved |
Antitrust Filing Review | 5-8 hours | 20-40 mins | Up to 90% |
Cyber Policy Scan | 3-5 hours | 15-30 mins | Up to 85% |
Loan Document Extraction | 10+ hours | 1 hour | 90%+ |
These improvements are particularly critical in high-volume, deadline-sensitive matters such as mergers, regulatory disclosures, or crisis response.
Historical Context: Why A&O Shearman Was Ready
A&O Shearman’s innovation track record dates back decades. Its precursor, Allen & Overy, pioneered AOSphere in 2002—one of the earliest SaaS platforms for risk management tools in law. While AOSphere was divested before the Shearman merger in 2023, its legacy continues in this agentic shift.
In 2023, A&O Shearman launched ContractMatrix in collaboration with Microsoft and Harvey—an AI tool for in-house counsel. That success helped lay the foundation for this deeper, enterprise-grade deployment of agentic systems.
This strategic evolution shows how A&O Shearman is building not just AI tools—but AI infrastructure around legal knowledge.
Market Impact: Redefining the Law Firm Business Model
The decision to sell agentic tools to other law firms might seem counterintuitive—why enable competitors? But this is a pre-emptive strike against commoditization.
As routine legal tasks get automated, law firms must evolve from service providers to solution developers. A&O Shearman is embracing this change by:
Productizing commoditizable work
Freeing up human lawyers for bespoke advisory
Capturing value from previously low-margin workflows
While this may not disrupt “bet-the-company” matters yet, it firmly establishes A&O Shearman as an innovation leader and tech integrator in legal practice.
“All lawyers working on antitrust matters have had that sinking feeling—usually around 3am—of ‘there must be an easier and quicker way of doing this’. Those days are fading fast.”— James Webber, Antitrust Partner, A&O Shearman
Challenges and Cautions: Will It Cannibalize Legal Work?
Despite the optimism, the deployment isn’t without strategic risks:
Revenue Cannibalization: Automating tasks might reduce billable hours, forcing shifts in pricing models.
Adoption Friction: Conservative firms may hesitate to trust AI agents with critical workflows.
Transparency Concerns: Clients may demand explainability—especially in high-stakes or regulated matters.
Still, the structured oversight and auditability of these agents mitigate some of these risks. Plus, the efficiency gains and commercial potential outweigh short-term disruptions.
The Legal Industry’s Next Chapter Has Begun
A&O Shearman’s agentic AI deployment with Harvey marks a landmark moment in legal history. It’s not just about efficiency—it’s about reimagining what it means to be a law firm in the digital age. With multi-agent reasoning systems, monetization through client tools, and strategic partnerships, A&O Shearman is not following legal tech trends—it is setting them.
As this model scales across more practice areas and client types, it could inspire a new legal market dynamic—one where human lawyers, intelligent agents, and legal IP co-create value in ways we’ve never seen before.
