Antidote, a provider of AI-based billing
compliance software for global law firms, has raised $5 million in a seed
funding round led by Lakestar, with participation from Concept Ventures, The
LegalTech Fund, and industry angel investors. The round follows a $2 million
pre-seed raise in 2025, bringing total funding to $7 million.
Law firms face increasing pressure to comply
with complex Outside Counsel Guidelines (OCGs) while often relying on manual,
end-of-month billing reviews that can result in write-offs, rejected invoices,
and strained client relationships. Current billing practices and OCG non‑compliance lead to 8–12 per cent of billable hours lost to
non-compliance write-offs and rejected invoices every year.
Antidote addresses these challenges by
integrating with existing time-recording and practice management systems to
review time entries in real time. The AI-powered platform checks entries
against client OCGs and internal firm standards, flags potential issues, and
suggests compliant revisions before invoices are submitted.
Nicholas d’Adhemar, founder and CEO of
Antidote, said the company was created in response to persistent revenue
leakage caused by manual billing compliance processes in law firms:
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.
Antidote is already used by law firms across
the US, UK, and Australia, reflecting demand for a more proactive and automated
approach to billing compliance.
The new funding will support Antidote’s next
phase of growth, with a focus on advancing its AI-powered billing compliance
platform and expanding its presence in the US.
The company plans to further develop its
product capabilities, deepen integrations with legal practice and timekeeping
systems, and scale adoption among law firms seeking to reduce billing friction
and revenue leakage through real-time, automated compliance.
