ADHDEV

ADHDEV is a Polish web development agency working with clients across Europe and the US. The company specializes in .NET, Kentico, and Umbraco development, positioning itself as a technology partner for digital agencies and software houses. They bring over ten years of experience and have completed hundreds of web projects. The team operates on a philosophy of cost-effectiveness—defined not as cheap work, but as delivering results without waste. They use AI tools to eliminate unnecessary process overhead, build solutions teams can manage internally, and integrate with existing systems rather than reinventing the wheel.

Services and capabilities

ADHDEV's core offerings revolve around three specialisms. Kentico development targets clients seeking a digital experience platform combining content management with marketing features across multiple channels. They position themselves as Kentico Partners with the depth to support delivery teams, maintain existing platforms, or launch new projects from scratch.

Umbraco development serves clients wanting a flexible, open-source content management system. ADHDEV offers full-lifecycle support: team augmentation, maintenance and ongoing development, or complete project kickoff.

Digital transformation covers custom .NET solutions tailored to specific business problems. The agency works on modernizing legacy systems, developing secure multi-site content management tools, building high-performance websites, and creating APIs and applications. Their approach emphasizes clear communication and reliable delivery without excessive back-and-forth.

Industry-specific work includes solutions for publishing and online media (gated content, subscription models, multi-channel content tools), oil and energy (legacy system modernization, secure multi-site CMS), and self-storage (website redesign, storage management system integration, ordering and customer service optimization).

Notable work

Oakwood Agency, a digital solutions firm, has worked with ADHDEV for four years. Matt Newman, their Digital Solutions Head, notes the agency acts "as an extension of our own team," helping maintain and improve existing websites and develop new digital solutions.

Emberson Marketing reports ADHDEV's work on a secure, well-performing portal "was instrumental in generating more business opportunities for our client" and received positive feedback from end users.

Euro Innowacje (CEO Marcin Król) completed a project with ADHDEV that "ran very smoothly and the outcome exceeded our expectations—it helped us build trust and start a solid business relationship."

How they work

ADHDEV offers a free consultation for new clients and provides a free UX audit (real designers reviewing your website as first-time users, no AI assistance or proprietary methodology). The agency emphasizes clear alignment from day one and transparent communication. They skip unnecessary process overhead by using AI tools strategically, and focus on delivering solutions that fit within clients' existing technical ecosystems rather than imposing new ones. Engagement typically flows from discovery through delivery with an emphasis on ongoing support and partnership rather than transactional handoff.
