Get found by Google.
Get cited by the machines.
Search is being rewritten. ChatGPT, Claude, Perplexity, Gemini, Copilot don't show ten blue links anymore - they answer. BARREK positions brands inside the generative engines and builds the AI systems that move the rest of the business.
Recognised as one of the fastest-growing IT & digital companies in Central & Eastern Europe.
SEO is for the old web.
We work the new one.
When someone asks an LLM "what's the best [your category] in Croatia?" - there's one answer, not ten links. GEO is the discipline of engineering that answer.
Two new disciplines.
Six proven ones.
We've been shipping digital solutions for nearly a decade. Now we're applying that same operational seriousness to the two disciplines that will define the next one.
Generative Engine Optimization
We engineer how ChatGPT, Claude, Perplexity, Gemini and Copilot cite, name, and recommend your brand.
The work breaks into two phases. First, a 14-day Visibility Audit across five generative engines. Then, a monthly GEO retainer - authority architecture, semantic content engineering, structured data, and citation hooks.
- LLM Visibility Audit - 200+ prompts, 5 engines, 14 days
- Authority architecture - content systems engineered for citation
- Schema & structured data - so models can quote you cleanly
- Weekly tracking - citation share, by prompt cluster, by engine
AI Strategy & Implementation
We design, build, and ship AI systems for real businesses - and provide the strategic thinking partnership leadership teams need.
Three engagement modes. Fractional AI strategy for executive teams. Agents & RAG systems for organisations ready to ship. And team enablement workshops for teams that need to put AI to work by Monday.
- Fractional AI strategy - monthly advisory for leadership
- AI agents & RAG systems - Claude, GPT, OSS - built and owned
- Workflow automation - n8n, Make, custom code
- Team enablement - workshops, EN/HR, half-day to three days
Mobile & web apps
Native iOS and Android apps, complex web platforms. Smart Lopar, AirQ Abu Dhabi, LORO Audit.
Custom digital solutions
Bespoke software built for specific client needs. Architecture, build, ship, maintain.
Websites & e-commerce
Modern websites and online stores. WordPress, headless, custom stacks where it makes sense.
Digital marketing
Google Ads, social campaigns, content production, social media management.
A method built for moving fast,
not for billing slow.
Most consultancies stall in discovery and deliver decks. We're structured around shipping the smallest version that proves the thesis - then compounding from there.
Diagnose
We test current visibility, infrastructure, and team capability. No assumptions.
Design
We architect the smallest intervention that produces measurable lift.
Deploy
We ship. Content, code, agents, citations - hands on keys, not on hips.
Defend
LLM rankings drift weekly. We monitor and defend your position.
Trusted across the
public and private sector.
From Croatian ministries and municipal governments to international enterprise and growth-stage clients - we've spent nine years building digital systems people actually rely on.
Built by an operator, not a deck shop.
BARREK was founded in 2017 after a decade inside one of Croatia's largest enterprise groups. The lesson: consultants who don't ship don't actually know how anything works.
Nine years on, we've delivered for Croatian ministries, municipal governments, EU-funded transformation programmes, and international enterprise clients. In 2024 we were recognised by Deloitte's Technology Fast 50 as one of Central & Eastern Europe's fastest-growing IT and digital companies.
Now we're applying that same standard of craft to the two disciplines that will define the next decade: GEO and applied AI consulting.
Strategy that actually ships.
With more than a decade in digital marketing and PR, Lennarta leads how BARREK's clients show up - and get remembered. As Marketing Director and Robert's closest collaborator, she turns positioning from a buzzword into a plan that holds up in the market.
She's hands-on across every major engagement, working directly with clients on positioning, content strategy, and the narrative that makes a brand the obvious choice. The throughline: strategy that's actually executed, not just presented.
It's the same standard of craft that defines the rest of the team - now pointed at the disciplines that decide who gets found and cited: brand positioning and content built for the way people search today. and client strategy.
Reasonable questions.
