Law.co

Background

Law.co is a cutting-edge AI platform for law firms, enabling attorneys to streamline legal research, automate contract review, and interact securely with legal content. From day one, Law.co required a legal LLM infrastructure that was secure, private, and customizable — designed for high-stakes, compliance-heavy environments.

They turned to LLM.co to build that foundation.

The Challenge

Unlike general-purpose AI solutions, Law.co needed:

• Private LLM deployment to satisfy data sovereignty and confidentiality requirements.
• Fine-tuned legal language models trained on statutes, regulations, and case law.
• Flexible architectures capable of on-premise, VPC, or hybrid deployments.
• Custom agents and features to serve the nuanced workflows of legal professionals.

Furthermore, Law.co’s clients — which range from boutique firms to Fortune 500 in-house legal departments — demanded white-glove customization of their AI solutions, tailored to their internal documents, compliance frameworks, and preferred workflows.

Our Solution

LLM.co delivered a suite of private LLM capabilities tailored to Law.co and its clients:

Private Legal LLM Infrastructure

We built Law.co’s core engine using hybrid private LLM architecture, combining open-weight foundation models with legal-specific fine-tuning, ensuring speed, performance, and compliance.

Custom Agents for Legal Workflows

From automated issue spotting in contracts to email summarization for case intake, we developed domain-specific agents to augment the Law.co interface — reducing hours of manual labor.

Multi-Tenant Customization for Law.co Clients

For Law.co clients needing fully private deployments, we offer bespoke LLM stacks — some hosted in VPC, others deployed locally. These tools are fine-tuned on client data, maintaining confidentiality and improving domain accuracy.

Legal Corpus Integration

We integrated private legal databases, statutes, and case law into vector stores and RAG (retrieval-augmented generation) pipelines, enabling clients to query their own knowledge bases safely and accurately.

The Results

• Law.co now supports hundreds of daily queries across its legal AI suite.
• Multiple law firms now use LLM.co-powered private LLMs to review contracts, summarize documents, and automate discovery — securely and at scale.
• The platform supports custom deployments for clients who want their own LLMs trained on internal legal precedent, briefs, or compliance documents.

Why It Matters

This case isn’t just about powering a single legaltech platform. It’s about enabling the next generation of AI-native law firms. With Law.co and LLM.co working hand-in-hand, firms now get:

• Compliance-first AI tooling
• Custom LLM solutions without public model risks
• Ongoing support and tuning as regulations and workloads evolve
