Adrian Sanchez de la Sierra. Deprecated.

Head of AI at Zartis — Anthropic's #1 European partner by client engagement volume. Through that role he sees roughly thirty client AI transformations a year. The publication is the residue.


Field notes · first person

I've been told to "lead AI adoption" three times in three different companies. The first time I assumed the problem was finding the right tools. The second I assumed it was training. The third time I noticed the pattern: every org I walked into had a different version of the same missing artifact — the inventory of what they were already doing.

At Zartis I get to run that experiment thirty times a year. Different sectors, different team sizes, different stages of denial. The variance in the strategy decks is high. The variance in what's actually shipping is low. Most rooms are running four to six unstructured agent setups, three or four conflicting CLAUDE.md hierarchies, and zero idea which of them are reaching the model on a given session.

"I'm not transforming anyone's organization. I'm translating organizations into something agents can work inside. The translation is the work."

What "thirty engagements a year" actually looks like

The publication exists because patterns repeat. The same five problems show up in different costumes across very different orgs. After the eighth engagement it stopped feeling like client work and started feeling like fieldwork. Each issue is a sanitized chapter from that fieldwork, paired with the working artifact that made the finding portable.

On the credential

Zartis is Anthropic's #1 European partner by client engagement volume. I lead AI there. That access is why this publication exists in this form — I get to watch the same problems land in thirty different rooms. It's also the only reason the course exists; I'm one of fewer than fifty people who can teach this from inside an active practice.

The credential is on the spine of every page because it explains the access. It is not on the hero of every page because the brand is anti-spectacle. The work has to do the lift.

On the persona

Deprecated is the byline. Same person. Different register. First person on case files; third person on product surfaces. The persona is allergic to hype, generic productivity language, and the entire AI-twin vocabulary. If you've read a piece that rhymes with "10x your team" or "transform your business," it didn't come from this address.
