(0 review)Responsible AI to empower your business
Areza is an AI-native growth agency for European B2B service firms — the legal, consulting, financial and professional-services companies that have hired agencies before and come away with a folder of slides instead of results. The difference is what you keep at the end. A traditional agency hands you a campaign that stops the moment the retainer ends. We hand you infrastructure that keeps running: AI SEO — content and technical work that ranks you in Google and, increasingly, inside the AI assistants your buyers now ask first: ChatGPT, Perplexity, Gemini and Google's AI Overviews. Search is moving from ten blue links to direct answers. Most agencies still optimise only for the old game. Conversion-ready websites — built in one focused sprint, designed to sell rather than to win design awards. You get a site that turns the traffic you already have into enquiries. AI voice agents — they answer inbound calls, qualify leads and book meetings around the clock, so a missed call at 9pm isn't a lost client. Agentic workflows — automations that take over repeatable operational work and keep running long after the project is handed over. We are deliberately anti-hype. If AI is the wrong tool for a problem, we say so — brand strategy, for instance, is human work and we won't pretend otherwise. Our credibility comes from refusing the easy sale and backing claims with numbers, not adjectives. We're a small, founder-led team based in Vilnius, Lithuania, serving clients across the UK, Germany, Sweden, Poland, Lithuania and the Netherlands. You work with the people doing the work, not an account manager relaying messages. What you take home is an asset that compounds: content that ranks for years, an agent that never sleeps, workflows that run without you. That's the whole point.
