Proof Technology Raises $30.4 Million Series B to Expand AI-Powered Legal Services Platform

Proof Technology, a Denver-based legal technology company that provides an online marketplace for litigation services including process serving, electronic court filing, and remote notarization, has raised a $30.4 million Series B funding round as it accelerates growth and enhances its platform for law firms and government agencies. The financing marks a significant step in the company’s expansion since its earlier institutional rounds and reflects growing demand for more efficient and transparent legal operations.

The Series B round was led by Long Ridge Equity Partners, a growth investment firm focused on financial and business technology, which provided the majority of capital for the round. Joining Long Ridge in the investment were existing backers Blue Heron Capital and The LegalTech Fund, both of which have supported Proof Technology through prior financing stages and bring deep expertise in legal technology and enterprise software.

Proof Technology’s Series B funding follows an earlier $7 million Series A round and represents a continuation of investor confidence in the company’s vision and execution. The Series A was co-led by Blue Heron Capital and The LegalTech Fund, with participation from Clio Ventures alongside other strategic investors. This earlier capital helped Proof scale its platform and expand its user base among legal professionals.

Founded and led by CEO Eric Voogt, Proof Technology connects law firms, attorneys general offices, and individual litigants with a nationwide network of process servers and supports the digital filing of court documents. The company’s platform uses proprietary AI-enhanced technology to analyze uploaded legal documents, extract key case information, and coordinate delivery or e-filing with appropriate service providers. Many legal professionals use the platform to reduce administrative burden, gain real-time visibility into document status, and comply with jurisdiction-specific requirements.

With more than 5,000 law firms and government agencies using the platform and handling nearly 20,000 document transactions per month, Proof has positioned itself as an important technology partner in modernizing the delivery of litigation services. The company’s technology integrates with popular case management systems used by legal professionals, enabling seamless workflows and stronger operational efficiency across legal practices.

The new funding will be used to accelerate revenue growth, expand electronic filing capabilities, enhance integrations with more legal software platforms, and further embed artificial intelligence into its services to improve automation and user experience. As legal departments and firms increasingly adopt technology to streamline operations, Proof’s marketplace seeks to replace outdated manual processes with more measurable, reliable workflows that are compatible with digital-first legal systems.

Long Ridge Equity Partners’ leadership in the Series B round underscores the investor’s belief in the potential of legal technology to transform legacy processes in the justice system. Blue Heron Capital and The LegalTech Fund’s continued participation signals sustained confidence from investors who have watched Proof grow from an early-stage startup into a company with nationwide traction and a growing footprint among legal practitioners.

Proof’s marketplace is designed to support a broad range of litigation tasks, from serving summonses, subpoenas, and complaints to managing court filing requirements across jurisdictions. Its AI capabilities help reduce errors and improve speed, while its nationwide network of service providers ensures coverage in urban, suburban, and rural areas. These features have broadened the platform’s appeal among law firms of different sizes and specializations.

By aligning technology with traditional litigation services, Proof Technology is at the forefront of legal industry innovation, aiming to become the go-to online marketplace where legal professionals can obtain all services requiring human intervention with greater transparency and efficiency. The Series B funding solidifies the company’s financial base as it advances product development and extends its market reach.

As legal practices continue to modernize operations and adopt digital solutions, Proof’s expanded funding will support its mission to simplify complex litigation workflows, making legal services more accessible and technologically sophisticated for law firms and government entities across the United States.
