About DeviLabs
DeviLabs started by using AI to make performance creative faster and better. Now we use the same obsession to make AI engines recommend the brands we work with.
DeviLabs is a Generative Engine Optimization (GEO) agency based in Wassenaar, the Netherlands, that gets DTC, ecommerce, SaaS and SMB brands cited and recommended in AI answers across ChatGPT, Perplexity, Gemini and Google AI Overviews. GEO at DeviLabs combines AI search optimization with traditional SEO foundations — entity optimization, structured data, citation-ready content and ongoing AI visibility tracking — backed by years of performance creative production that converts the traffic once it lands. We serve clients across the European Union and the United States.
01Founder
I founded DeviLabs and I still run both halves of it — the GEO practice and the AI-native creative production — from Wassenaar, the Netherlands. I started it because I kept seeing the same gap: brands buying visibility they could not convert, and creative nobody could tie back to a number. Five years in SEO and AI-generated creative, since before either went mainstream, turned into one agency that handles both.
The way I work is simple: baseline first, opinion second. Before I touch anything I measure where your brand stands on a fixed set of prompts, then re-run those same prompts on the same cadence so you can see movement instead of taking my word for it. When something is a judgment call, I say it is a judgment call. I would rather lose an argument than sell you a number I cannot stand behind.
And I keep the client list small on purpose. Every brand I take on, I want to understand properly — the margins, the returning-customer rate, what your buyers actually type into ChatGPT at 11pm. That is not something you can do well for fifty companies at once, so I do not try. You get my attention and my direct line, not a template with your logo dropped into it.
A short list I know well beats a long list I service at arm’s length.
If it does not move citations, CPA or ROAS, it did not happen — however good it looked.
The tools make it fast. I still make the call on what is good enough to ship with your name on it.
02Where we came from
Great performance creative starts with understanding the buyer — what they want, what they fear, what makes them act. GEO starts in exactly the same place: understanding what your buyers ask AI engines, and making sure the answer is you. Different surface, same craft. We research the questions, engineer the content and structure AI engines trust, and back it with creative that converts the demand once it arrives.
We have worked in SEO and AI-generated creative for five years — since before either went mainstream. That started with using AI to make performance creative faster and better, and led directly into Generative Engine Optimization: the same obsession with what actually moves numbers, applied to the layer where AI engines decide which brands to name. DeviLabs was the first agency to bring GEO to the Lithuanian market.
That discipline is what we now point at AI search. The engines your buyers ask — ChatGPT, Perplexity, Gemini, Google AI Overviews — decide which brands get named long before anyone reaches a website. Getting into those answers is a systems problem, not a content problem: entity clarity, structured data, extractable content, third-party corroboration, measured on a fixed cadence. It is the same work we have always done, applied one step earlier in the buying journey.
Not an agency that added AI later. AI production was the model from the beginning — video, static and UGC-style creative at a speed and cost traditional studios could not match.
Years of performance creative for DTC and ecommerce brands, judged on CPA and ROAS rather than on how the work looked in a deck.
GEO is our lead service. We get brands cited in AI answers — then use the creative side of the business to convert the buyers who arrive.

04How we work
Most brands buy AI visibility from one vendor and creative from another, then discover the traffic does not convert. We own both halves, so the buyer an AI engine sends you actually lands somewhere built to sell.
We baseline your AI visibility on a fixed prompt set before we touch anything, then re-run the same prompts on the same cadence. Same method every time, so the numbers mean something.
We were building with these tools before it was a positioning statement. That means realistic judgment about what AI does well, what it does badly, and where a human still has to make the call.
GEO is a young practice and AI answers are volatile. We publish our methodology alongside any number we report, and we will tell you when something is a judgment call rather than a measured result.
