Syntracts Raises $5.3M for On-Prem Legal AI Platform

Syntracts, an API-first contract intelligence platform built for full on-premises deployment, has closed a $5.3M seed round led by Hyperplane. The round includes participation from Khosla Ventures, Top Harvest Capital, and Fortitude Ventures, along with continued backing from existing investors Myriad Venture Partners and Point72 Ventures.

The funding will help Syntracts expand its reach across BigLaw and corporate legal teams. The startup recently secured a multi-year partnership with an AmLaw 25 firm after competitive evaluations and was selected for A&O Shearman’s Fuse incubator, a program designed to identify standout legal innovation.

Building Secure Infrastructure for Legal AI

Law firms face a difficult choice when adopting AI. They need accuracy and speed, but they can’t compromise on privacy or data security. Syntracts addresses this by serving as a secure infrastructure layer that sits beneath existing workflows and AI tools.

The platform works through an API that allows teams to pull documents from systems like iManage, NetDocs, or SharePoint. It then organizes those documents into structured, searchable data and sends the results back into whatever tools the firm already uses—dashboards, AI assistants, or knowledge management systems. Every step happens within the firm’s own environment. Nothing leaves their walls.

“Our mission is simple: enable law firms to use AI that’s both private and verifiable,” said Doug Bemis, co-founder of Syntracts and former CTO at Uber AI Labs. “Firms don’t need another app — they need a secure data layer that powers their existing AI with clean, structured knowledge from their own contracts. That’s Syntracts: infrastructure that runs fully on-prem and makes what they already use smarter, faster, and more reliable.”

Why Privacy Matters in Legal Tech

Unlike many legal AI tools that depend on third-party APIs or cloud-hosted large language models, Syntracts runs entirely on-premises. The company uses specialized models fine-tuned with synthetic legal data derived from each client’s own documents. This approach makes existing AI tools smarter and more contextually aware without exposing sensitive information to outside systems.

The result is outputs that lawyers can actually use—structured, auditable, and consistent. Syntracts cuts contract review time by at least 80%, turning hours of work into minutes while maintaining the control and transparency that generic prompting can’t provide.

“In law, you shouldn’t have to choose between airtight privacy and answers that are consistent and reliable,” said Christopher Martin, co-founder of Syntracts. “We’re building the secure AI backbone for the legal industry — one that helps firms unlock the full value of their data safely and at scale. The backing from Hyperplane, Myriad Venture Partners, Khosla Ventures, and Point72 Ventures highlights how critical a privacy-first foundation is to the future of legal AI.”

How the Funding Will Be Used

The new capital will go toward accelerating adoption among BigLaw and corporate legal teams. Syntracts plans to invest in product development, expand its go-to-market efforts, and grow its team to support increasing demand from firms that need secure, reliable AI infrastructure.

The company is also focused on deepening integrations with the tools legal teams already rely on. By making it easier for firms to adopt Syntracts without overhauling their existing tech stack, the startup aims to become the default infrastructure layer for legal AI.

Solving AI’s Accuracy Problem

Accuracy remains one of the biggest barriers to AI adoption in law. First-generation legal AI tools could read contracts, but they struggled to understand the relationships between deal points or the structure of a transaction.

“First-generation legal AI tools could read contracts, but they couldn’t understand them because they lacked the context of how deal points relate to each other within a transaction,” said Chris Fisher, founder and managing partner at Myriad Venture Partners. “Syntracts solves that with custom-trained models that capture not just terms, but the structure and relationships between those terms, delivering true deal intelligence. And they’re doing it entirely on-premise, which we believe is the only viable path for handling confidential transaction data.”

Syntracts tackles this by training models on synthetic data that reflects the structure and language of each firm’s specific contracts. The platform doesn’t just extract information—it understands how different terms relate to each other, giving firms what amounts to deal intelligence rather than keyword searches.

About the Company

Syntracts was co-founded by Doug Bemis, former CTO at Uber AI Labs, and Christopher Martin, a veteran of Big Law. The combination of deep AI expertise and firsthand legal experience has shaped the company’s approach to building technology that actually fits into how law firms work.

The startup focuses on API-first design, which means firms can integrate Syntracts into their existing systems rather than asking lawyers to learn new software. Documents come in, structured data goes out, and everything stays within the client’s environment.

What sets Syntracts apart is its commitment to running entirely on-premises. While many AI tools require cloud access or third-party APIs, Syntracts keeps all data inside the firm’s infrastructure. For legal teams handling confidential transactions, this isn’t just a feature—it’s a requirement.

Investor Perspective on Legal AI

Investors see Syntracts as addressing one of the most pressing challenges in legal tech: how to make AI accurate and trustworthy without sacrificing privacy.

“As AI adoption accelerates across the legal and enterprise markets, the biggest challenge users face is accuracy and trust,” said John Murphy, co-founder and managing partner at Hyperplane. “What excites us about Syntracts is their approach to solving this through small, specialized language models trained on proprietary synthetic data. The platform seamlessly integrates into existing workflows and AI tools, delivering unrivaled accuracy, transparency, and privacy.”

The round includes a mix of investors with backgrounds in enterprise software, AI, and venture capital. Hyperplane, Khosla Ventures, Point72 Ventures, Myriad Venture Partners, Top Harvest Capital, and Fortitude Ventures all participated in the seed round.
