Antidote, an AI-powered automated billing compliance platform for global law firms, announced it has raised a $5 million Seed round led by Lakestar, with participation from Concept Ventures, The LegalTech Fund (TLTF), and a group of prominent industry angels. This follows the company’s earlier $2 million pre-seed round in 2025, bringing total funding raised to $7 million.
Funding accelerates product development and US expansion, building on adoption by leading firms across the US, UK, and Australia. Current billing practices and OCG non-compliance lead to 8–12% of billable hours lost to non-compliance write-offs and rejected invoices every year. An AI platform automatically extracts rules from clients’ Outside Counsel Guidelines, checks time entries against client rules, details any violations, and provides compliant time entries, reducing write-offs and improving client trust.
Nicholas d’Adhemar, Founder and CEO of Antidote, said: “Law firm billing compliance is one of the biggest sources of revenue leakage inside firms, not to mention being a generally despised manual task that adds to client friction. We built Antidote to remove billing friction by automating compliance for law firms, removing the manual work and shifting compliance upstream, when the work is done, not when you’re trying to send out the bill.”
Navid Meyer, Venture Partner at Lakestar, said: “Antidote is solving a deeply embedded and very expensive problem in the legal industry, and Nicholas brings rare credibility here. He’s lived the problem as both a lawyer and a private equity client and has already built and scaled legaltech startups into category-defining platforms for legal spend management. We’re backing Antidote because it combines a clear product advantage with a founder who has proven he can execute in this market.”
