Experts' advice at every stage

It's okay if you're not tech-savvy, we are. That's why you come to us. Our value-first approach is what drives us in any custom product development. We'll advise you at every step of the way to ultimately build a product that solves your business's real needs.

Direct client-team interaction

Nobody likes multiple levels of communication, maybe only in the Gartic Phone game. That's why we promote transparency and direct communication between the software development team and product stakeholders. This is our secret sauce.

Here's how we develop custom software

We've tested several development models when it comes to software. Our experience has proven that the most effective of all are Agile and Lean. These allow us to deliver value at every stage of the process in custom product development:

    1.   Product Discovery & Research - We gather and analyze requirements, form product documentation, and specifications (SRS).

    2.   UX/UI Design & Prototyping - We apply a design-thinking approach to anticipate users' needs, flows, and identify the best solutions to solve them. 

    3.   Product Development - We plan releases and continue with implementation according to Agile. We work mainly with Scrum, Kanban, and Scrumban.

    4.   Testing (QA) - We run different types of testing to ensure that the products run smoothly and are bug-free.

    5.   Release, Monitoring & Support - Our work doesn't end when the product goes live. We provide ongoing support if you don't have in-house experts.
