Liam Fallen

I build AI agents, and I got here in a slightly odd order. Football came first, then a school I left with no qualifications. After that I did two years of exams in one, went to Sheffield Hallam and moved into technical SEO, living and working all over the world along the way.

Football

Football was the main thing for most of my childhood. I played as much as I could, and I was good enough to get scouted.

I spent three years playing for the youth team of a club that's won the Premier League. Then life got in the way and I stopped playing at that level.

It was the first time I'd spent years trying to get properly good at something, and I've gone about most things the same way since.

School and Sheffield Hallam

I grew up working class and went to what was officially the worst school in Britain at the time.

I left with no qualifications.

I didn't fancy waiting around after that, so I did my GCSEs and A-levels in one year. Most people take two years or more to get through them. It was an intense year, and I wouldn't recommend it to everyone, but it worked.

At the end of it I had an interview at Oxford University.

I went to Sheffield Hallam after that. One intense year had taken me from no qualifications to a university place.

Technical SEO

For most of the time since university I've worked in technical SEO.

That's basically working out why a website isn't showing up in search the way it should, then fixing it. I did it for more than eight years as a consultant and strategist, with companies like monday.com, Riverside and LeoVegas, and for It's Nice That.

In iGaming, which is about as competitive as search gets, I ranked first across 16 of the biggest iGaming sites. Several SEO publications and LinkedIn named me the top technical SEO in the world.

I also founded Mostly SEO, a marketing community that started out as Mostly Marketing. I still run it.

  • No. 1 technical SEO in the world, according to several SEO publications and LinkedIn

AI agents

I've been building AI agent workflows and automations for several years. I've always liked learning new things, and AI keeps giving me something new to learn, so it was a pretty natural move.

Technical SEO turned out to be good practice for it. Most of that job is working out how a system fits together, finding the part that's broken and fixing it, and building an agent takes a lot of the same thinking.

Recently I've been doing a lot of that in Grok Bot, mostly building agents that handle the boring jobs people would rather not do themselves. Once a month I send one of them free to my newsletter, so there's always a new one on the go.

Cycling

Outside work I'm usually on a road bike. A typical ride for me is between 100 and 150km, and I go to the gym as well.

When I was living abroad I set up a cycling community, and it grew to more than 250 people. We've ridden together in a lot of different countries, and two of our members got married after meeting on one of our rides.

What I'm like to work with

I'd rather not describe myself, so here's what some of the people I've worked with wrote on LinkedIn.

Liam has the funniest brain muscle on LinkedIn.

Alpana Chand

  • …he can also write in a way that makes people think and feel something. He possesses the rare ability to make those around him feel validated and appreciated, consistently championing the work of others rather than claiming credit for himself.

    Erica Ylimäki Head of Marketing at MedicubeX

  • He not only taught me but also gave me the freedom to work independently. This pushed me to new levels of creativity and showed me the kind of leader Liam is.

  • Liam is a pleasure to work with, he is kind, efficient, intelligent, and organised, which makes any collaboration very easy and enjoyable!

    Vladi Kriulin

    Bruna Cecilio

  • Liam brings a set of expert eyes to a project, he's someone who will hold you to account, push for higher evidence-based standards… He also has your long term interests in mind - he leaves you in a better position having passed on increased understanding…

    Sune Nightingale Renewable heating expert

  • Liam is also an excellent communicator in guiding you through the many aspects which combine to make an effective strategy.

    Simon Smith Head of Content at It's Nice That

  • …you can rarely find a person… willing to share all secrets, but also kind and good human being.
