What Lucio does
Lucio is an AI-native legal workspace platform founded in 2022 by Vasu Aggarwal and Darsan Guruvayurappan, two law school classmates who identified repetitive work as a major productivity drain for junior lawyers at Indian firms. The company, headquartered in Bengaluru with US sales offices in New York and Los Angeles, sells a unified subscription product ($149 per user per month, no minimum seats) that combines a conversational research assistant (Lucio Assistant), Microsoft Word and Outlook plugins, and a centralized workflow hub (Lucio Studio) covering legal research, document review, contract drafting, due diligence, and chronology generation. Underlying architecture is model-agnostic and built on Microsoft Azure and Google Cloud Platform, with firm-specific knowledge layered on top of third-party LLMs and contractual commitments that client data is not used for model training.
The platform is distributed through a hybrid go-to-market motion combining self-serve product-led growth with white-glove enterprise onboarding by in-house legal engineers, alongside dedicated account executives in the US and curated dinner events for mid-market firm leaders. Lucio holds enterprise-grade security certifications including ISO 27001:2022, SOC 2 Type II, GDPR, CCPA, UAE PDPL, and DPDP ACT, and is backed financially by Microsoft and Google in addition to its $5 million October 2025 round led by DeVC and Ashish Kacholia. The company serves 3,500+ users across 9+ jurisdictions with named customers including Trilegal, Hadef & Partners, WMHW, S&R Associates, Luthra and Luthra, TT&A, and Falcon Rappaport, and operates academic partnerships with King's College London and NUS Faculty of Law to seed long-term practitioner adoption.
