Law firms say they’re built to serve clients. In truth, they're built to serve their partners.

Blackletter raised $6M to put clients first. Led by @LererHippeau with the CEOs of @cohere, @twelvelabs and @adaption_ai.

75+ clients, from day-to-day work to @WindBorneWx's $37M Series B.

Great being on the show! Always love talking with @mattybcohen. This was a fun conversation.

He went from @Harvard_Law to employee #20 at @cohere . Now he's building Canada’s first AI-Native law firm, Blackletter (blackletterfirm.com) .

Jon Rosenbluth was one of the few in his Harvard Law class who didn't go into law. But after seeing countless founders lose time and money to billable hours, he wanted to build a firm that would change that.

So, he left Cohere to fix a system that hasn't changed in 70 years.

Now, his team at Blackletter consists of elite lawyers AND machines working together. The system checks for errors and stays online 24/7. But most importantly, the lawyers remain the key judgment layer, and clients are charged a flat fee.

This week on @TankTalkPodcast with Jon Rosebluth, we cover:

02:14 - His career journey from Harvard to McKinsey to Cohere
07:48 - The real case for joining an early-stage startup
15:47 - Why build an entire law firm instead of just another legal tech tool?
19:39 - Problems that most founders face with the current legal system
24:51 - Where software hands off to human lawyers
32:15 - What the law firm of the future actually looks like

Crazy to see Iran coverage right now. This AM I had to scroll past ~7 sections on the NYT homepage to find it. Below Saks bankruptcy and Jodie Foster stories. Main article calls it a “crackdown” and buries commentary on civilians being killed (and underestimates it too).

Tool use is an exciting part of Command-R

At a category level, we're moving from LLMs as The Product to LLMs as components of The Product. It started w/ RAG & now includes tool use

So what? Builders will incorporate agents in products — making life & systems easier to navigate

Something I glossed over in yesterday's release of Command-R, is the Tool Use API we released alongside the model.

I want to say more about that and share some benchmarks on ToolTalk.

Really excited about Command-R -- a model designed for use in production. Check out Aidan's thread below for more info!

Introducing Command-R, a model focused on scalability, RAG, and Tool Use. We've also released the weights for research use, we hope they're useful to the community!
