Types of websites

The web is the first contact with your brand - and often determines trust even before the first conversation. We build presentation websites that communicate brand positioning, generate demand, and scale along with your business. 

Presentation websites

Do you want to present your company or brand? We create presentation websites that communicate brand positioning, values, and expertise. For B2B companies, manufacturers, financial institutions, and professional services. 

Presentation websites

Lead generation websites

A lead generation website is primarily a powerful business tool for acquiring contacts, building trust, and supporting business growth. At ui42, we design and develop conversion-focused websites, from a clear value proposition through a thoughtful structure to form optimization and performance measurement. We create solutions that turn traffic into real business opportunities.

Media portals, magazines, and content platforms

Solutions for editorial offices and publishers who work with content on a large scale.

Types of web applications

The web application addresses what common tools cannot handle. It digitizes processes that are unique to your business - partner sales, production, field operations, internal administration, customer service. From strategic discovery through UX and development to integrations and evolutionary development.

Portal for your subscribers, business partners, distribution network - with individual price lists, real-time stock statuses, approval workflow, and full integration with ERP.

Internal company systems and process applications

Applications that replace Excel, emails, and paper processes are designed according to the real functioning of the company. We configure workflows, data, and integrations precisely to your processes. Data is collected and processed directly in the system and seamlessly flows between different parts of the company - without manual rewriting, losses, or delays.

Internal corporate systems and custom process applications

Custom manufacturing and warehouse applications

Digitization of production and warehouse logistics. Systems connect orders, production, and warehouse into a single controlled flow. Interfaces are linked to both ERP and the production line, allowing operators to work in a unified environment without manual data re-entry. The result is fewer errors, faster processing, and an up-to-date overview of the production and warehouse status in real-time.

Custom manufacturing and warehouse applications

An authenticated environment where the customer manages services without the need to contact support. Orders, invoices, services, requests - all in one place. Connected to internal systems, always with up-to-date data.
