TL;DRCarta acquired Avantia, a UK-based AI-powered law firm for asset managers, launching Carta Law as an integrated legal and compliance layer inside its private capital ERP platform. The deal is Carta’s fourth acquisition since October 2025, following Accelex, Sirvatus, and ListAlpha. Avantia was founded in 2019 by James Sutton, serves 200+ asset managers including 30% of the world’s largest funds across $15 trillion in AUM, and built an AI workflow engine called Ava. Carta Law connects legal work directly to fund operations on a single platform. Carta hit $500M revenue in 2025.
Carta has spent the past eight months buying its way toward something that did not exist a year ago: a single platform that handles dealmaking, fund operations, investor relations, and now legal and compliance work for the private capital industry. The acquisition of Avantia, a UK-based AI-powered law firm for asset managers, is the company’s fourth deal since October 2025 and the one that makes the strategy hardest to ignore. Carta is no longer a cap-table company. It is building an enterprise operating system for private markets, and it has decided that system needs its own law firm.
The new entity, Carta Law, combines Avantia’s regulated legal practice and its AI workflow engine, Ava, with Carta’s fund administration and portfolio management infrastructure. The pitch is that private equity and venture capital firms should no longer need to send routine legal work, fund formation documents, subscription agreements, KYC and AML checks, compliance filings, to outside counsel at hourly rates. Instead, Carta Law promises AI-native delivery with outcome-based pricing and lawyer-backed review, all connected to the same system of record that already holds the firm’s cap tables, valuations, and investor data.
