Carta acquires UK firm Avantia to launch integrated legal arm, Carta Law
Carta acquired UK law firm Avantia in June 2024 to launch Carta Law and offer tech-enabled legal services.
Why it matters: The move enables Carta to deliver regulated legal advice directly within its tech platform for private markets. This integration could simplify compliance and streamline legal workflows for clients managing complex equity and business deals.
- Carta acquired Avantia, a UK Alternative Business Structure (ABS), on June 10, 2024.
- Avantia, licensed by the Solicitors Regulation Authority, offers multidisciplinary services beyond traditional law.
- As of June 2024, Avantia is rebranded as Carta Law, serving private market clients through Carta's platform.
- Avantia introduced 'Ava,' an AI-powered legal workflow assistant, in January 2025.
- The SRA ABS register lists Avantia at firm number 655756.
On June 10, 2024, Carta completed its acquisition of Avantia, a UK law firm licensed as an Alternative Business Structure (ABS) by the Solicitors Regulation Authority (SRA). An ABS allows law firms non-lawyer ownership and the delivery of legal and non-legal services under one regulated umbrella—uncommon in the UK legal tech market.
- Avantia, established in 2018, focused on integrating legal expertise with technology for corporate clients.
- Following the acquisition, Avantia was rebranded as Carta Law and now operates from London as a legal arm for Carta’s clients in private markets, with firm number 655756 verified in the SRA ABS register.
- In January 2025, the firm launched 'Ava,' an AI-powered agent designed to automate routine legal tasks like document preparation and due diligence, with James Sutton, founder, stating Ava "lets lawyers spend more time on complex matters."
Carta’s integration of regulated legal services into its platform allows clients—especially those handling equity issuance, cap table management, or fundraising—to address compliance and legal needs without switching providers. This could save time and mitigate regulatory risk for in-house teams and deal professionals.
Industry observers note the deal continues a trend of tech companies seeking SRA-regulated status to expand legal offerings, as seen with firms like PwC and EY. Legal commentator Anna Bradshaw, writing in Legal Futures, said, "ABS licensing is reshaping how external investment flows into legal services and how firms structure for multidisciplinary delivery."
While financial details were not disclosed, SRA records and Legaltech News independently confirm the acquisition and the launch of Carta Law.
By the numbers:
- 2018 — Avantia founded as a tech-integrated law firm in London.
- June 10, 2024 — Date of Carta's acquisition of Avantia.
- January 2025 — Launch of AI legal assistant 'Ava' within Carta Law.
Yes, but: Neither Carta nor Avantia have detailed how Ava will be integrated into Carta's broader tech platform, or any changes to client pricing.
What's next: Details on the rollout of Ava within Carta’s client workflow are expected from Carta Law in late 2025.
