What is the purpose of Wexler’s AI‑driven litigation platform?
You're always marketing yourself in one way or another. I think the litigators are going to want to prepare like an athlete preparing for the big race. AI that can help you play out different scenarios, using the facts, training up, putting someone on the stand, having a sort of sparring partner with a judge or arbitrator. Those are all the things that we're really interested in. The workflow at Wexler would be to build a chronology and then we even have a verify button where you go through and you verify the facts that are in that chronology at the point of finalizing it. That process of verification doesn't just make sure it's accurate, but it also makes sure you've got your fingers on the documents.
So you're actually reading the documents themselves as they should be read exactly as they would look if you printed them out, which is really important. It might take three hours to do a chronology in Wexler. It doesn't take three minutes and it doesn't take three days. But those three hours not only help you get the best output, but they also help you become an expert in the case.
On today's Legally Speaking podcast, I'm delighted to be joined by Gregory Mostyn. Gregory is the co-founder and CEO of Wexler. Wexler offers advanced AI-driven solutions for e-discovery, document review, and litigation services. With clients including the likes of Clifford Chance, Herbert Smith, Freehills Kramer, and Burge Salmon, Wexler's on a mission to solve the most complex cases. So a very big warm welcome to the show, Gregory. Thanks, Rob. Nice to see you. ah it's actually a pleasure to have you on the show and looking forward to diving into all the great stuff you're doing in around the world of law before we do that got a couple of serious questions what is your favorite beverage and what is your preferred choice of footwear on a typical work day
Beverage. I'm a sucker for Diet Coke, I'm afraid. Bit of a bad habit. DCs, I used to call them. Yeah, I think I powered my university with a sort of diet of Diet Coke, if you like, revising for finals where I got addicted. So I try and limit my Diet Coke intake. Footwear, very much trainers. I'm not sort of running around in Birkenstocks like some of the tech founders I know, but trainers, but not sort of suited and booted every day. Unlike one of my colleagues who's a former lawyer who insists on remaining smart, even in the kind of startup environment. So, yeah. There we go. I like it.
Bit of chalk and cheese. And yeah, I have to confess, I do like the odd DC as well. All right. Before we get in too much of a rabbit hole, let's talk a bit more about you. Would you mind telling our listeners a bit about your background and career journey?
Yeah, so I've had a peripatetic career, if you like. I studied at Oxford a while ago now. And I think the first thing you should know about me is that I'm from a family of lawyers. So my dad was a barrister and then a judge. My brother's a partner at Cleary. My stepmum's a barrister. I've grown up surrounded by the law and barristers. Every kind of dinner party my parents hosted was talking about this or that case. Sunday lunches, big debates about the latest and greatest in what was going on in the kind of world of law and how that, you know, more broadly impacts the world in general. So that's the kind of personal connection to this in terms of me myself. So I was very set on working in the music industry when I was at university.
I founded a few different events, businesses, and I thought I was going to become music mogul and went into that real life. Well, it was actually great. I mean, I learned so much and I very quickly rose, rose up in the, in a sort of events company, but realize there's definitely a bit of a ceiling there.
How did Gregory Mostyn’s personal and professional background shape Wexler?
and wanted to sort of challenge myself a bit more. So I moved on to something which was sort of bridge between the tech worlds and the music world. And my thing was marketing. So I did marketing and sales, but all about kind of selling in a B2B and a B2C way. So my thing, I suppose I'm good at commercializing
