Custom software development for companies of any size

Enterprise software development

The main business of big enterprises is often quite far from technology and custom programming services.

We work hard to precisely match technologies to your needs. You’ll clearly see the correlation between resources spent on IT and the impact on your core business. We’ll advise you on the best tech stack or platform to optimize and streamline the custom software development process.

Frequently asked questions

Intellias provides flexible and adjustable pricing models for our custom programming services, with the option to combine different engagement models for specific services within the same project. Every engagement is unique, and estimates for the cost of custom application development services may vary depending on the complexity of the project and your desired involvement in the management of the development team.
At Intellias, we work with custom programming projects of any size, scale, and complexity. We pick the cooperation model that’s most suitable depending on a client’s previous experience and needs as well as the project’s complexity: dedicated development team, managed delivery, or product development. Each of these models covers a different set of needs and entails a different way in which our experts engage in developing custom-built software — performing exclusively engineering tasks; managing a full range of engineering projects, supervised teams, or programs; or developing a holistic product from the initial idea stage through bringing it to the market.
Intellias will establish a successful framework for remote communication between your in-house team and your remote Intellias team at the start of your custom application development project. In order to allocate a sufficient amount of time for initial team alignment and knowledge transfer, the Intellias team will adjust its work schedule to achieve a better time overlap. We will communicate with the tools you prefer to use with a custom application development company.
As a leading custom application development company, we pay attention to the continuous growth of our employees and their job satisfaction. We’ve established a Professional Development Department whose responsibility is to provide high-quality education for Intellias employees. All employees have their own Personal Development Plans (PDPs) based on which they attend professional internal trainings as well as online and offline external courses, conferences, and workshops.
Intellias complies with intellectual property (IP) protection standards and follows strict non-disclosure agreements (NDAs) to avoid potential data leaks or disclosure of information during custom business application development projects of any complexity.
