I'm the founder of Keniri, which I've worked on full-time since it launched in October 2026, and of Socion. I'm based in London. Before that I spent nine years at Reach plc — one of the UK's largest digital publishers — moving from digital production and business analysis into data over time. For the last four of those years, the work was product-facing: designing and analysing A/B tests, investigating user behaviour with BigQuery and Athena, and turning results into recommendations for product managers and senior stakeholders.
In parallel, I've spent over 22 years researching and writing about Socionics — a personality theory developed in the 1970s by Lithuanian researcher Aushra Augusta, built on Jungian foundations and centred on how different types interact with each other rather than just who they are individually.
The two things are less disconnected than they appear. At Reach, the work was about understanding behaviour at population scale — millions of sessions, experiment readouts, patterns in aggregate data. Socionics works at a different resolution: the specific dynamic between two people, named and characterised. One zooms out, the other zooms in. The underlying curiosity about why people behave as they do connects them.
The books
I wrote Your Social World Explained as the first serious English-language treatment of what I call the SLIDE System — a modernisation of classical Socionics designed to make the theory accessible without sacrificing its rigour. That was followed by the Socionics Made Simple series: 16 Kindle volumes, one for every type in the system.
The free reference site behind the books is Socionics Insight — 372 pages covering all 16 types, all 16 intertype relations, cognitive functions, and more. The leading English-language Socionics reference online.
There are also two memoirs: Escaping the Vulture's Shadow (2024), the personal story behind the research — two decades inside the psychiatric system, and how Socionics became the framework that helped me rebuild — and Stern by Name, Stern by Nature (2014), its raw, unedited companion, written from inside the recovery itself. Together they're the "why" behind everything else on this page.
The analyst work
Nine years of product and experimentation analytics at Reach plc — experiment readouts across 65+ titles, a painted-door subscription test, and a feature case that shipped and is still live. The work page has the background and outcomes, and the case studies walk through three experiments start to decision.
What I’m building
The Socionics research eventually led to Socion — a matching app where you choose the intertype dynamic rather than delegating that decision to an algorithm — which I now build and run as founder. Free to join, with a premium tier for those who want the full experience.
My main focus now is Keniri, a voice conversation that helps you understand yourself and the people you care about. You talk out loud for about fifteen minutes and get a plain-language picture of how you think, what you need, and why some relationships come easily while others take work. It launched in October 2026, and you can start a conversation free.
