[Read on Substack](https://legaltechtrends.substack.com/p/legal-tech-trends-newsletter-50) · 2026-03-16 · Legal Tech Trends --- Happy Monday, and welcome to the 50th edition of Legal Tech Trends!👋 This week's edition comes to you a little early. I wanted to get ahead of a busy schedule and make sure it still goes out this week. This milestone edition features a few spotlight moments: a fun chat on the Non-Billable Podcast, a Bloomberg Law article on training 3,000+ lawyers in GenAI, and a Legalweek Award for Factor's Sensemaker Academy. ☕ Subscribe now My Work Selection of highlights from the Bloomberg Law article. (Full article linked below) Over the past year, Factor’s Sensemaker Academy trained more than 3,000 lawyers in GenAI. Alex Denniston and I outline our top learnings in Bloomberg Law, but I want to highlight one here, because it still amazes me how few people know about it. Hallucinated citations continue to make headlines. But that’s just the tip of the iceberg, and many lawyers don't grasp GenAI's broader limitations. I’d estimate that fewer than 25% of users realise that large language models struggle with numbers. LLMs are fantastic at language, but lawyers also contend with precise numbers: key dates, deadlines, limitation periods, and financial calculations. Yes, reasoning models are more capable (if still imperfect), but users don’t always select them, and products don’t always auto-route to them. Running calculations in deterministic code, essentially calling a calculator, is a far better approach. Yet many LegalTech products can’t execute code, and even products that can may not always call a tool when required. This is a major AI blind spot that most users don’t know exists. Numeric calculations are particularly problematic because we’ve grown so used to computers being fantastic at precise calculations, but LLMs aren’t. It’s worrying how few people know this. For every hallucinated case in the courts (1,080+ and counting), how many miscalculated dates, missed deadlines, and faulty financial calculations are regularly going out to clients every day? Fortunately, you're now up to speed on this particular critical limitation!👏 Know someone who'd benefit from this? Pass it along… 🏆 Legalweek Leaders in Tech Law Awards 2026: Nice to see our approach to training and delivery recognised; Factor's Sensemaker Academy took home Best Tech Training Program. LINK 🎙️ ‘AI is a top priority’: The tech bets reshaping Big Law I had a great chat with Oliver Attinger on the Non-Billable Podcast. We cover why firms are buying general-purpose legal AI platforms, where point solutions fit in, and the smart bets for the future. I’ve been running multiple RFPs with the major platforms, using these products extensively, and driving adoption at scale, so this conversation is rooted in hands-on experiences. LINK AI Harvey and Legora continue to dominate headlines, announcing fundraising, acquisitions, partnerships, and key client wins at a ferocious pace! ✨ Legora’s Monster Raise & Recent Highlights $550M Series D: Roughly tripled its valuation to $5.55 billion, from the $1.8 billion Series C in October. New offices planned in Houston and Chicago, with a target of 300+ US employees by the end of 2026. LINK Walter AI Acquisition: First acquisition, strengthens Canadian foothold. LINK Barclays: Global rollout across in-house legal. LINK Herbert Smith Freehills Kramer: Firmwide adoption announced. LINK 💡Bain on Second-Mover Advantage: An interesting piece on Legora’s trajectory and why being second can win. LINK 🚀 Harvey’s Expanding Ecosystem & Recent Highlights I attended the Harvey Forum in London last month. The side-chats I had were great, and the long-horizon agent demos highlighted a hugely exciting direction of travel. TLTF Partnership: Partnered with The LegalTech Fund to co-invest in LegalTech startups. LINK Lume Acquisition: Second acquisition of 2026, picking up AI customer integration platform Lume. LINK Microsoft 365 Copilot: Direct integration announced. LINK Intapp Ethical Walls: Partnered with Intapp to embed ethical wall enforcement directly into the platform. LINK 🧠 The Claude-Native Law Firm Lawyer Zack Shapiro’s viral post (7+ million views) detailed how his two-person firm uses customised Claude skills to dramatically accelerate their service delivery. LINK Sidenote: Claude Code/Cowork is transforming how I work. Important considerations remain for deploying this in Big Law, but anyone who hasn't tried these products is likely underestimating where AI capabilities stand right now. The capability leap feels like another ChatGPT moment. (PS - I encountered many bugs on Cowork, so I now typically use Claude Code, which is more stable) 🤖 LegalTech Giants Align with Anthropic’s Claude A wave of major LegalTech companies announced Claude integrations. Thomson Reuters is building the next generation of CoCounsel Legal on Claude and the Agent SDK. LexisNexis has integrated the tech into Protégé. Harvey has expanded its Claude capabilities. And DeepJudge, the legal search platform, has connected to Claude Cowork via MCP. LINK 💻 Microsoft Launches Copilot Cowork Microsoft announced Copilot Cowork, an AI agent tool developed in collaboration with Anthropic that enables the autonomous completion of multi-step tasks across Microsoft 365 applications. Powered by Work IQ, Cowork grounds tasks in emails, meetings, messages and files. LINK Sidenote: A big announcement given Microsoft’s reach, and how incredible Claude Cowork is, but given Copilot's lukewarm debut, I'll reserve judgment until we see this in action. It remains to be seen which models and usage limits will be offered. Acquisitions 🤝 HaystackID Acquires eDiscovery AI HaystackID has acquired eDiscovery AI in a deal aimed at strengthening HaystackID's GenAI capabilities across litigation, compliance, regulatory response, internal investigations, and cybersecurity.

LINK 🎤 Last call for early-stage startups: LegalTechTalk's LegalTech Launchpad entries close tonight. LINK Cautionary Tech Tales A few stories that serve as useful warnings… 🔒 McKinsey AI Chatbot Breach Exposes 46.5 Million Messages Security researchers exploited a vulnerability in McKinsey’s internal AI chatbot, gaining full database access within two hours and exposing 46.5 million chat messages and 728,000 files of confidential client data. A sharp reminder of the risks when systems are not properly secured. LINK Sidenote: It's important to bear these risks in mind as enthusiasm grows for lawyers building their own solutions! 🚨 LexisNexis Data Breach LexisNexis confirmed a data breach after hackers leaked over 2GB of stolen data, though the compromised systems mostly held legacy data, and no sensitive PII or financial information was exposed. LINK ⚖️ Solicitor Faces Probe After Uploading Client Documents to ChatGPT The SRA is investigating an immigration solicitor after the Upper Tribunal found that uploading client documents to ChatGPT constituted a breach of confidentiality and waived legal privilege. The tribunal warned that using free consumer AI tools to process confidential information places the data in the public domain. LINK 📋 Court Rules AI Tool Use Ends Attorney-Client Privilege And on the other side of the pond, the US District Court for the Southern District of New York has ruled that documents generated by a criminal defendant using a consumer-grade artificial intelligence tool – Anthropic’s Claude – were not protected by attorney-client privilege or work-product protection. LINK Podcasts 🎙️ EP #68: Private Equity in Law Firms: Risks, Multiples, and Value Creation Private equity investment remains one of the hottest topics in the industry.
