Dominykas Jankauskas

What does Dominykas Jankauskas do at DeviLabs?

He founded DeviLabs and directs both halves of what the agency sells. On the GEO side that means AI visibility audits, entity and schema optimization, citation-ready content, conversational query research, authority and citation building, llms.txt and technical GEO setup, and ongoing AI visibility tracking. On the creative side it means AI-native video and static production — the performance creative that converts the traffic once an AI answer or a search result sends it.

DeviLabs started by using AI to make performance creative faster and better. The agency now applies the same approach one layer up: making AI engines recommend the brands it works with. Dominykas runs both practices as a single service rather than two separate offers, on the argument that visibility without conversion is a vanity metric.

What has he worked on?

Two engagements are published in full on this site, with the deliverables and timelines stated rather than summarised:

• Post-Peak — nine Meta-ready AI video assets produced for a DTC supplement brand over a one-month engagement, each asset shipped in one to three days. The work covered AI UGC ads, a 60-second AI VSL, and fully localized Lithuanian voiceovers on existing English creative, produced without a camera, studio, on-set day or local voice talent.
• Nike AI ad concept — a self-initiated, clearly labelled spec project testing what a single operator could produce in under a week using only publicly available AI tools. Built solo in four days with Nano Banana Pro, Kling 3.0, Higgsfield and CapCut.

Further client work is collected on the work page.

How does he approach AI production?

The position DeviLabs takes publicly, and which Dominykas sets, is that AI is the engine and judgment is the difference: volume and speed are worth nothing if the output does not carry the brand or convert. That shows up in how the agency writes about its own results — it publishes what it can evidence and says so plainly when it cannot. DeviLabs has not yet published a GEO case study, because the GEO practice is new and the agency does not publish results it cannot measure.

Where is Dominykas Jankauskas based?

He is based in Wassenaar, the Netherlands, where DeviLabs is registered as a working address: Dennenlaan 15, 2244AK Wassenaar. The agency serves clients across the European Union and the United States.
