We have raised a $550M Series E at an $8.8B valuation, led by Atreides. Every major existing investor is back in, and we’re welcoming Baron Capital, Capital Group, Fidelity, Glade Brook and J.P. Morgan. We picked investors who think in decades. Several of them work with law firms and legal teams every day, so they can see where the work is heading. Lawyers are moving from AI assistants to agents that do multi-step work. The money goes there. We’re growing our teams across North America, Europe, Latin America and Asia-Pacific, and going deeper on the Legora aOS. Thank you to the 1,000+ people at Legora, and to the 140,000 legal professionals who use what we build. I say this a lot because I believe it: it’s the best time in history to be a lawyer. We're thankful to be a part of it. Full story: legora.com/blog/series-e

Kurt has built Corient into one of the most impressive firms in wealth management. A great conversation on the enormous opportunity to innovate and shape the future of the industry. Highly recommend giving it a listen.
Kurt MacAlpine’s company manages $525 billion and it didn’t even exist six years ago. At 39, he set his sights on the ultra-high-net-worth wealth management industry and decided to take it over as if he were a Canadian Genghis Khan. He went into debt to fund acquisitions, and when the stock market turned against his strategy he kept buying back shares and eventually took the company private. This is a fascinating conversation about incentives, conviction, and building a business that can compound for generations. 0:00 Building Corient and managing $525 billion 5:32 Why wealth management’s incentives are broken 11:42 Bringing the partnership model to wealth management 22:15 Sharing the benefits of scale with clients 24:25 One compensation plan, one P&L, no exceptions 27:58 Why independent wealth managers join Corient 39:21 Staying the course when the stock market disagrees 48:25 Betting on the business through share buybacks 51:52 Taking CI Financial private with Mubadala Capital 59:08 Acquiring great partners and building one company 1:04:43 Giving employees a voice in building the brand 1:12:39 Building a business that lasts for generations Includes paid partnerships.

I was in the Bloomberg studio in London this morning. Q3 was the most hectic quarter in @WeareLegora's history. We added 800 new customers in three months and now work with more than 2,300 across 80+ countries. We also added more ARR this quarter than our total ARR at the end of 2025. I was asked the jobs question, and my answer hasn't changed: our customers are hiring more lawyers. Legal is supply constrained. If you could review every contract, you would. If you could run full diligence on every asset before it goes to investment committee, you would. Better tools mean more of that work gets done, and a lawyer still owns the judgment. We talked about junior lawyers wondering whether they need to learn to code. With large language models, the programming language is English. I'm not especially good with words. Lawyers are, and they turn out to be some of the best drivers of our product. I've said it before, and I'll say it again: I think this is the best time in history to be a lawyer. Thanks @TomMackenzieTV for having me on The Opening Trade. Full interview below.

Legora has crossed $200M ARR. In our 2026 State of Scaling report, we highlighted the company’s climb from $1M to $100M ARR in just 18 months. The next $100M came in less than six. Since we partnered with @MaxJunestrand, @siggelabor, and the team a year and a half ago in their Series B, @WeAreLegora has grown to 130,000 monthly users across 2,100 firms and legal teams in 80+ countries, with the US now its largest market by revenue. It’s been a privilege to watch this team build with such speed and rigor. Congratulations to everyone at Legora on an extraordinary milestone.

This week, we brought all of @ElevenLabs together. 800 of us, from 50 countries! Remote-first has been a superpower for us, but there’s nothing like having everyone in one place and feeling the energy across the team. Now onwards - so much more to build!

Anthropic, Legora, Sierra, ElevenLabs, OpenAI, and Glean are reaching $100M ARR in one to three years, a milestone that used to take software companies five or more. The growth curve for AI-native companies looks fundamentally different. More on what sets the outliers apart: bit.ly/4hcZT0P Disclaimer: bit.ly/3H4dQj0

What separates the software companies pulling ahead from the ones falling behind? @alexrkonrad dug into our latest research and put it plainly. His piece highlights some of the key signals we identified in our report: faster paths to $100M ARR, sustained new-logo growth, aggressive investment, and improving burn at scale.

There is no best model. There's a lot of noise about models right now. Who is training them, who owns them, where legal intelligence should live. One question actually matters: what produces the best outcome for the legal task in front of you? That's how we decide things at @WeareLegora. We optimize for the end-to-end outcome on a legal task. The model is one layer of that system, not the system. Models are uneven and the frontier changes almost weekly. One model plans a long job well, another runs deep analysis across thousands of documents. Some have to be told exactly what to do, and some are fine with a vague brief. They all break in different ways. So our lawyers write evals and we test them with the Legora BAR, our benchmark for agentic reasoning. Every model takes every test, and the model that wins gets the work. We post-train when we know it buys our customers better performance on a specialized task. Training is a tool we reach for when it helps, nothing more than that. The intelligence that compounds sits in the orchestration layer. Precedents, review standards, client requirements. That knowledge has to stay editable, auditable and portable. In our system, a changed review standard is an edit that takes effect the same day, with no new model training required. No lawyer should have to worry about which model did the work, any more than they think about which chip is in their laptop. They should only care about the quality of the work. That's what we are focused on. If you want the engineering version of this argument rather than the CEO version, our CPO, Bryan Tsao, and CTO, @jacsebl, take it apart in the video below.

Who owns the model? Where should a legal team's intelligence live? These questions are at the center of many conversations in legal AI, but we think the most important question to answer is: what produces the best outcome for every legal task? As CTO @jacsebl and CPO Bryan Tsao explain, there is no best model. Different models lead on different tasks, and the frontier changes almost weekly. At Legora, we use the best available model for each task, and invest in the system, where intelligence compounds and remains editable, auditable, and portable. We post-train when we know it delivers our customers better performance on a specialized task. Training is a tool, not a strategy. No lawyer should have to worry about which model did the work. Just whether the work holds up.

I first came to San Francisco when I was 15, with my dad. He is a programmer. To a teenager from a small island outside of Stockholm, this was the place where the future was being built. We walked into Salesforce East and stood there watching the enormous digital display of moving water. Outside, Salesforce Tower was starting to rise. I remember looking up and thinking it would be pretty sweet to have a tower someday. We are not there yet. What I could not have known is that I would be back years later, having dinner with @Benioff and welcoming @salesforce as a @WeAreLegora customer. Salesforce's Legal and Corporate Affairs organization will now use Legora across North America, EMEA and APAC. Their lawyers keep the judgment calls. We take care of the work around them. We have run on Slack since day one and became Salesforce customers when our sales team outgrew its first CRM, so it is good to have it run in the other direction too. Welcome to Legora, Salesforce. Dad, this one feels special.

For the first time, firms can build compounding engines of institutional knowledge. Those that succeed will become massively more valuable than those that don't.

Legora's revenue has increased by over 9x from this time a year ago. That's an astounding growth rate for a company of this size. It's not unusual for a startup to grow that fast in the first 6 months, but Legora is 3 years in.
The momentum continues at @WeAreLegora ...we beat our original Q3 '26 plan a full month early. July was the strongest quarter-opening month in Legora's history, and August was even larger. Total net new ARR grew 36% MoM. But the story of the month is in-house teams. ARR from in-house is up 15x+ YoY, average ARR per in-house customer is up 2.5x+ YoY, and in-house teams are now almost half of our total new customers. Most importantly, you earn ARR by building the best product on the market. Our usage climbs every month: 16+ hours per monthly active user. In September, we expect to add more ARR than in all of Q1 '26 combined, which would make Q3 the best quarter in our history and capture yet another ARR milestone. LFG!
