Advocacy Raises $3.5M to Cure AI's 'Hallucination' Problem in Law

SAN FRANCISCO, CA – March 06, 2026

A new legal technology startup, Advocacy, has emerged from stealth with $3.5 million in seed funding to tackle one of the most perilous challenges in modern law: the unreliability of artificial intelligence. As litigators increasingly experiment with AI, they face the career-threatening risk of "hallucinations"—AI-generated fabrications, from non-existent case law to misstated facts—that have already led to court sanctions and professional embarrassment. Advocacy aims to solve this accuracy crisis with an AI-native workspace designed to provide something generic tools cannot: deep, unwavering case context.

The funding round was led by venture firm Relentless, with significant participation from legal tech giant Relativity, through its innovation arm Rel Labs, and Am Law 100 firm Fenwick & West LLP. The investment signals a strong vote of confidence from both the tech investment community and the legal industry itself that specialized, high-accuracy AI is the only viable path forward.

The High Cost of the AI Accuracy Gap

The rapid adoption of generative AI has created a paradox for the legal profession. While the potential for efficiency is immense, the risk associated with generic, large-language models has proven to be a minefield. Recent years have seen numerous high-profile incidents where lawyers have submitted briefs to courts containing fictitious case citations generated by popular AI tools. The fallout has been severe, resulting in public admonishments, financial penalties, and a growing skepticism toward AI's role in high-stakes legal work.

This "accuracy gap" is what Advocacy was built to close. The problem stems from the fact that general-purpose AI models lack a cohesive, memory-based understanding of a specific legal matter. They operate on vast but disconnected datasets, unable to grasp the intricate web of facts, evidence, and arguments that define a complex case.

“In litigation, an AI hallucination is a career ender," said Damir Becirovic, founding partner at Relentless. "That’s why the hype cycle tools are failing while Advocacy is winning. They have solved the accuracy gap and earned the trust of the nation’s top trial lawyers by delivering the only thing that matters: flawless context."

A 'Case Memory' to Combat Inaccuracy

Advocacy’s solution moves beyond the standalone, task-based functions of most legal AI tools. Instead, it positions itself as a "context-driven memory layer" that sits across a firm's entire litigation technology stack. The platform is designed to centralize the fragmented intelligence of a case—which traditionally lives in disconnected e-discovery platforms, legal research tools, document folders, and litigators' minds—into a single, unified workspace.

This "case memory" platform ingests and organizes all matter-critical information, creating a continuously enriched digital desk for the legal team. By shifting from simple keyword searches to what the company calls "context orchestration," the system builds an institutional knowledge base for each case.

“AI can assist with discrete tasks, but litigation demands continuity and context,” said Téo Doremus, CEO and co-founder of Advocacy, who brings experience as a litigator to the company's leadership. “Litigation teams need more than standalone tools. They need memory-driven infrastructure that understands their case as deeply as they do."

The company reports that this model has already been proven with paying clients and in active pilots with top-tier law firms. Its latest deployment expands this capability, allowing the platform to ingest, process, and map new data types like raw audio and video evidence directly into the case timeline, ensuring the AI's contextual awareness grows with every new piece of information.

'Smart Capital' Bets on a Specialized Solution

The composition of Advocacy's seed round investors is as significant as the amount raised. The investment from Relentless provides strong venture backing, while the participation of Relativity and Fenwick & West represents a powerful industry endorsement.

Relativity, a dominant force in e-discovery and legal data management, made the investment through Rel Labs, its innovation hub launched in late 2025 to fund strategic technologies that extend its core RelativityOne platform. This partnership suggests a deep potential for integration, allowing Advocacy's contextual AI to leverage the vast document and data repositories already managed within the Relativity ecosystem.

The investment from Fenwick & West, a top law firm deeply embedded in the tech industry, serves as a crucial validation from an intended end-user. It indicates that practitioners on the front lines see a tangible need and a credible solution in Advocacy's platform. The round was further supported by a consortium of legal scholars from top-14 law schools and partners from other Big Law and boutique litigation firms, underscoring a broad consensus on the problem and the promise of this approach.

With the new capital, Advocacy plans to expand its product and engineering teams and scale its customer support infrastructure. A key part of this expansion includes hiring "specialized legal alignment experts" tasked with working directly with practice groups. This initiative aims to ensure the AI continually adapts to the nuanced demands of different areas of complex litigation, creating a feedback loop that refines the platform's accuracy and utility. The company will also focus on deepening its strategic partnership with Relativity, further cementing its role within the established legal tech landscape.

The company's recent recognition as a finalist for the Legalweek Leaders in Tech Law Awards in the Litigation Technology category further validates its innovative approach ahead of its planned appearance at Legalweek New York, where it will engage with firm leaders exploring AI adoption.
