Billing accuracy has become a mounting concern inside global law firms as clients impose increasingly complex guidelines and firms struggle with outdated, manual review processes. Into this gap steps Antidote, a fast growing legal technology company that uses artificial intelligence to eliminate billing friction and protect firm revenue. The company has now strengthened its position with a substantial seed funding round.
A Significant Seed Raise to Fuel Growth
Antidote has raised five million dollars in seed funding. The round was led by Lakestar with participation from Concept Ventures, The LegalTech Fund and a group of industry angel investors. Combined with its two million dollar pre seed raise in 2025, the company has now secured a total of seven million dollars to scale its platform and expand internationally.
The new capital will support product development, integrations with major legal systems and expansion in the United States where demand for billing automation continues to rise.
The Hidden Cost of Manual Billing Compliance
Law firms face growing pressure to comply with detailed Outside Counsel Guidelines that govern billing practices, task descriptions, rates and client specific requirements. Yet many firms still rely on end of month manual reviews to detect compliance issues.
This reactive process often results in significant financial loss. Industry data shows that between eight and twelve per cent of billable hours are lost every year due to write offs, rejected invoices and non compliant entries. Beyond revenue leakage, these errors can undermine trust with clients and strain long term relationships.
Antidote was created to address these costly inefficiencies by moving compliance checks upstream to the moment work is recorded rather than waiting until invoices are generated.
AI Powered Real Time Review
Antidote integrates directly with a firm’s existing time recording and practice management systems. The platform reviews each time entry in real time, checking it against client guidelines and internal firm policies. If an entry appears non compliant, the system flags the issue and suggests a corrected version that aligns with the client’s requirements.
Founder and chief executive Nicholas d Adhemar explains that Antidote was born from witnessing persistent revenue leakage caused by manual compliance reviews. He says the goal is to remove billing friction altogether by ensuring compliance while the work is done rather than relying on late stage corrections.
This proactive approach helps firms avoid write offs, improve billing accuracy and accelerate invoice approval cycles.
Growing Global Adoption
Antidote is already in use among law firms across the United States, the United Kingdom and Australia. Adoption has been driven by firms seeking to reduce administrative burden, improve real time visibility into billing compliance and protect revenue from preventable errors.
For many firms, the platform also helps strengthen client relationships by ensuring invoices consistently meet strict service level and documentation expectations.
Funding to Deepen Integrations and Expand AI Capabilities
The new investment will support the next phase of Antidote’s development. This includes enhancing the underlying AI models, expanding the platform’s ability to interpret complex guidelines and increasing support for diverse global billing requirements.
The company also plans to deepen its integrations with legal practice management and timekeeping systems, enabling frictionless onboarding for law firms of all sizes. With stronger integrations, Antidote aims to become an essential compliance layer embedded directly into daily attorney workflows.
A major focus will be on scaling adoption among large firms, particularly in the United States where compliance related write offs are a growing concern.
Positioning for the Future of Legal Billing
As law firms move toward more automated and data driven operations, Antidote is positioning itself as a core part of the next generation legal technology stack. By eliminating manual review cycles, reducing revenue leakage and supporting stronger client compliance, the platform aims to redefine how firms manage billing from day one.
With fresh capital, expanding global traction and a rapidly maturing AI engine, Antidote is on track to become a central technology layer for the future of legal billing compliance.
