Antidote Legal automates billing compliance for law firms by checking time entries against outside counsel guidelines (OCGs) as work is recorded, rather than weeks later during billing review. The AI platform identifies non-compliant entries, suggests corrections, and sends fixes directly to fee earners’ email for approval. Co-founded by Nicholas d’Adhemar, former CEO of Apperio (well-known UK legal spend analytics platform). London-based. Raised $5M seed round led by Lakestar (Jan 2026). Claims firms lose 6-10% of revenue to manual billing compliance review. Addresses the ‘Saturday Morning Problem’ — partners spending weekends manually reviewing and rewriting time entries. Built by lawyers who’ve lived the billing compliance frustration. Listed on LawTech UK ecosystem, Crunchbase, Tracxn, F6S. Covered by The SaaS News and multiple LinkedIn legal tech publications. Very early stage (founded ~2025, funded Jan 2026) but with experienced legal tech founder and significant institutional backing.

Workflows
Based on practitioner evidence, Antidote Legal is used in these workflows:
What practitioners struggle with
Real frustrations from legal professionals — the problems Antidote Legal addresses (or should address). Sourced from practitioner reviews, Reddit threads, and case studies.
Attorneys reconstruct their day at 9pm, guessing at time entries — studies show 10-15% of billable hours vanish when you don't track in real time
BigLaw billing coordinators spend days processing proformas — reviewing each partner's time entries, applying billing guidelines, adjusting rates, and generating invoices across hundreds of matters monthly
Corporate client sends a 50-page outside counsel guidelines document with 200+ billing rules — block billing prohibitions, task code requirements, rate caps, travel restrictions, staffing limitations — and the billing coordinator spends two days manually extracting and entering these rules into the billing system, only to discover six months later that timekeepers have been violating rules nobody told them about, resulting in $80K in rejected invoices
