Carta introduces Carta Law following the acquisition of Avantia, marking its fourth transaction in eight months.

      TL;DR Carta has acquired Avantia, an AI-driven law firm based in the UK that serves asset managers, launching Carta Law as a legal and compliance component within its private capital ERP platform. This marks Carta's fourth acquisition since October 2025, following Accelex, Sirvatus, and ListAlpha. Founded in 2019 by James Sutton, Avantia works with over 200 asset managers, including 30% of the largest global funds with a total AUM of $15 trillion, and created an AI workflow engine called Ava. Carta Law integrates legal processes with fund operations on one platform. Carta reached $500 million in revenue in 2025.

      Over the past eight months, Carta has been on a mission to establish a comprehensive platform for the private capital sector that encompasses dealmaking, fund operations, investor relations, and now legal and compliance needs. The acquisition of Avantia significantly enhances this strategy, signaling a shift from a focus solely on cap-tables to the development of an enterprise operating system for private markets, which now includes a law firm.

      Carta Law merges Avantia’s regulated legal services and AI workflow, Ava, with Carta’s existing fund administration and portfolio management systems. The aim is to provide private equity and venture capital firms with an efficient alternative to outsourcing routine legal tasks, such as fund formation and compliance checks, to external law firms at hourly rates. Carta Law offers AI-driven solutions with outcome-based pricing and human attorney reviews, all integrated into the same platform that manages cap tables, valuations, and investor information.

The Avantia acquisition is part of a clear pattern. In October 2025, Carta purchased Accelex, an AI data extraction platform for alternative investments, and also acquired Sirvatus, a loan administration solution for private credit fund CFOs. In March 2026, it added ListAlpha, a deal-flow and relationship management platform, and launched Carta CRM. Each acquisition has addressed different aspects of the private capital workflow and has been integrated under the Carta brand.

      Henry Ward, Carta’s CEO, has articulated the rationale behind these moves. He noted that large private equity firms are paying top-notch law firms for high-volume, essentially routine legal work, which they shouldn't need to do. While many enterprise software companies claim to reduce inefficiency, Carta's approach is distinctive. Rather than offering legal software for law firms, Carta is evolving into a law firm itself—one that is regulated and licensed, integrated within a technology platform.

      What Avantia built

      Founded in 2019 by James Sutton, a former solicitor at Slaughter and May, Avantia was established as an alternative business structure under UK law. This allowed it to combine licensed legal professionals with tech-driven workflows, unlike traditional law firms. Avantia secured seed funding from Hoxton Ventures, Smedvig VC, and Ace Cap.

      At the time of acquisition, Avantia was trusted by over 200 global asset managers, which includes 30% of the largest funds worldwide, managing transactions totaling over $15 trillion. Its AI platform, Ava, is designed to handle high-volume transactional tasks, contracts, compliance audits, and regulatory filings, which are then verified by human attorneys. Avantia claimed that Ava is the first AI agent developed by a law firm, a portrayal that has yet to be independently validated but contributed to its appeal to Carta.

      The integration enables Carta Law to link legal and compliance actions to the fund ledger seamlessly. For instance, a subscription agreement assessed by Ava integrates into the system managing the investor’s capital account. A KYC check simultaneously refreshes compliance records and fund administration. Additionally, Carta is incorporating AI models like Claude across its platform, with specialized agents facilitating connections among deal sourcing, portfolio analysis, and LP engagement relative to the fund ledger.

      The trust question

      Carta's ambition to serve as the operating system for private capital carries inherent risks. In January 2024, the company faced a credibility challenge when a sales employee misused confidential cap-table data to pursue a secondary share transaction without the concerned company's knowledge. This incident prompted Carta to withdraw from the secondary trading sector, and Ward acknowledged that even the mere perception of data misuse could undermine trust.

      This context is significant because Carta Law will require access to even more sensitive data than cap-table management. Legal and compliance workflows encompass privileged communications, investor identities, regulatory disclosures, and critical contractual terms, all of which are highly sensitive financial information. The argument for integration—linking legal work to fund operations to mitigate friction and costs—also raises concerns about consolidating vast amounts of sensitive data within a single platform. For firms mindful of the 2024 incident, the benefits of integration must be balanced against the potential repercussions of a similar issue arising.
