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. In addition, it can relate to several industries, which makes it hard to find ready solutions that can be used without any customizations. That’s why we start every engagement with enterprise clients by understanding their business and defining their specific needs to solve them with custom software development solutions.

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. Our technological guidance for enterprises is your ticket to hassle-free digital transformation, which inevitably is overtaking the enterprise sector.

Midsize businesses and products

After your software product has paid off and is loved by loyal users, your next step is to ensure round-the-clock performance. Adding new features may lead to product complexity, while a growing user base can overload the system. We’re all in to support you at this stage. Our custom software programming and infrastructure management practices will keep your product up and running and overcome bottlenecks.

Our custom programming and reliability engineering services guarantee your solution is available for a growing user base. Using our custom software application development services, you can focus on your market and users while we cover all the engineering, testing, and maintenance work. Your users will be glad to see regular updates and stable performance, ensuring your business can grow sustainably in the future.

Funded technology startups

We believe in your idea to solve people’s most complex challenges with your product. Nevertheless, even the bravest entrepreneurs require enough experience and technological expertise to keep up with the disruptive market. When working with startups, we try our best to shorten the time to market and provide our custom software development services at the scale required for a marketable product.

To find the best approach for accelerating your time to market, we’ll assess how your present development works to help you cope with your desired pace and quality. Next, we’ll offer what’s on our side to optimize custom programming processes and provide the required custom software developers for your product. With our complete solution guidance and DevOps advisory, you’ll be able to fluently transition from brilliant idea to tangible feature.

Frequently asked questions about custom application development services

What is your pricing for custom programming services?
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.
What does your model of cooperation for custom-built software development look like?
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.
Can you describe your remote communication process while delivering custom application development services?
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.
How does Intellias enhance the professional development of its employees?
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.
How do you ensure intellectual property protection during a custom business application development project?
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.
