The power of web

Web browser has never been more powerful. They offer the fastest signup path and the lowest customer acquisition costs, allow us to quickly test the MVPs, and offer great solutions working on all screens.

What is your digital strategy?

New venture

Are you building a new venture based on the web interface? We can offer a complex service starting from UX design and customer interviews through development and maintenance services. Our custom solutions are based on low-code technology, which guarantees a short time to market and affordable budgets. Your future portal could be easily integrated with all kinds of social media logins, payments systems, chats, and chatbots and can support notifications and ticketing systems.

Management tool

If you want to build custom web applications that digitalize existing business processes, we can help you integrate this new solution with your infrastructure and user management system. We support all SSO services and have experience in integrating with enterprise-grade systems like SAP, MS Dynamics and others.

New SaaS product

We can help you to offer your new services by building a web portal where user can easily log in, also with their social media accounts, manage their product, order a subscription with a free trial period and different payment methods, manage their users, and grant different level of permissions depending on a selected plan.

Migration of an existing web portal

Is your business dependent on existing legacy software? This can limit the implementation of the new features or even put your entire business at risk. In both cases, you should consider engaging a new software provider who could run an audit and assessment of the existing web portal and its infrastructure and help you build a roadmap of migration that will meet your business priorities.
