15+ Top Custom Software Development Companies [May 2024]

Top custom software development companies – shortlist

Here's a list of the best companies that offer custom software development services:

These 16 companies are the top ones on the market, but they also offer different solutions, approaches, and services. You need to pick the one that fits your exact needs by yourself.

Companies are ranked according to their ability to quickly make an impact on a project.

Comparison: characteristics of each custom software development company

Let’s start with comparing the maturity of each company - expressed by the years of experience - and potential availability of developers - expressed by the team size.

Consider these aspects carefully especially if your project is big. And by big, we mean huge budget and/or demand for a big team.

Years of experience

A graph comparing top software development companies by the time the are present on the market.

Custom software development companies that are present on the market for a long time:

  • often achieved great  maturity of processes,
  • have chosen their favourite industries and already gained experience in these fields.

Custom development companies that are present on the market for a shorter time:

  • have less experience and less fixed processes (5-6 years is often the time needed to structure the processes and gain experience as a team),
  • have a fresh look, are not opinionated, offer more flexibility.

Team size

A graph that presents how big are the teams in various top custom software development companies.

Bigger companies:

  • often need many formalities to begin the cooperation but it depends on their culture,
  • can provide you with a big team of developers and supporting roles.

Smaller companies:

  • often work in a more agile way,
  • want to prove their expertise caring about each client,
  • can accelerate many formalities, so the project can start quicker,
  • may not be able to provide you with a big team if you need one.

Is there a correlation between the company size and the ability to start a project quickly?

Often there's not. There may be many developers on board, but the company needs to maintain a sufficient buffer to be able to start a project quickly.

Comparison: custom software development companies' attitude to delivering results

Reviews are not enough - what characterizes the best custom software development company?

Most rankings present reviews and general information about companies and their services. And that's (especially reviews) important, there's no doubt.

But what about a company’s way of delivering products and attitude towards cooperation with clients?

And this is exactly what differs one dev shop from another.

You most likely have experience researching and figuring it out on your own, don't you?

6 components that add up to how your collaboration with a chosen company will look:

  • focus on business success,
  • knowledge-sharing culture,
  • smooth cooperation between business, tech, and operations,
  • time to impact,
  • taking ownership,
  • being a highly engaged partner.

The companies’ attitude to deliver products was assessed based on:

  • How they were engaging in the previous projects.
  • What clients are saying about them in reviews and testimonials.
  • What they talk about themselves on their website, blog, and social media channels.

Focus on business success, not delivering features

A graph that compares how various top custom software development companies focus on the business success of their clients.

Focusing on business success of a product means much more than understanding vision and requirements. It means helping to choose direction and features that will bring the best business results and then organizing the whole project around that. On a daily basis, it means prioritizing development of new features from the most profitable ones.

Why that's important?

  • without that focus developers would just code one feature after another, without trying to understand the "why",
  • not focusing on business results may end up with developing an unsuccessful product no one needs, that brings low ROI.

Real business support manifests in:

  • challenging your ideas and advising what you can do better during the discovery phase and then on a daily basis,
  • gathering a cross-functional team by one table to talk about your business goals and plan how to deliver them in the most time- and cost-effective way,
  • including a business analyst in a team from the very beginning,
  • having developers with proper business knowledge or supporting them with tech advisors.
In today's world, it's super easy to say that, hey, I didn't deliver something in scope and in time because it's agile and everything changed. But actually it's not true. It means that you didn't control the change in a way that will not be affecting your project so much. So what we are focusing on is to actually deliver what we what we agreed in terms of the scope, time, and budget with our customer. And it doesn't mean that it will not change, but we need to be able to control how the change is happening. - Aleksandra Gepert-Kraujutowicz, Head of Delivery at Brainhub

Consultancy approach - knowledge-sharing culture

A graph comparing top custom software development companies and their approach to share knowledge with clients.

Knowledge-sharing culture, or consultancy approach, means teaching, mentoring, and sharing knowledge with you and your team.

A company that manifests a strong consultancy approach not only delivers code, but also teaches your developers how to write it better and more efficiently, helps you to improve processes, and sometimes offers something more, like the support of Agile coaches, marketing team, or growth advisors for your developers.

Why that's important?

  • Your team learns a lot of new stuff, you improve the quality and efficiency of software development and know exactly how it is being done. After some time, you are able to continue on your own. That's added value from collaboration with a decent dev shop.
  • You can benefit from the services of various specialists like growth advisors who plan the development paths for your engineers.
  • Sharing knowledge increases transparency and improves collaboration between team members.

DevOps culture - smooth cooperation and no knowledge silos

A graph comparing best custom software development companies' levels of DevOps culture.

Working in alliance with DevOps (or BizDevOps culture) means removing the boundaries between developers, operations, and business teams.

Best custom software development companies provide multidisciplinary teams and promote close collaboration. Transparency and frequent deployments increase the satisfaction of developers – and, as a consequence, of the users of your product.

Why that's important?

  • No boundaries smoothen the cooperation, speed up the decision-making process, shorten the feedback loop and accelerate the development process.
  • Frequent deployments and frequent testing allows to spot problems and bugs quickly.
  • DevOps culture makes the whole process more efficient and more satisfying for developers.

<span class="colorbox1" fs-test-element="box1"><p>A custom software development company that works in line with DevOps culture and loves to share knowledge is pure gold. You can make your processes a lot better by working with them.</p></span>

Time to impact - how quickly they make a change?

A graph that presents how quickly best custom software development companies can make an impact.

Time to impact depends on:

  • how a company manages its resources (for example, if it maintains a sufficient buffer of developers who can jump right in),
  • number and complexity of formalities needed before they can start (often bigger dev shops need more time for formalities than the smaller ones),
  • time needed for onboarding.

Time to impact can be shortened by adding tech advisors to a team in the very beginning - they can quickly spot problems and suggest improvements. It can be also influenced by the way a company manages projects (fast iterations often mean fast improvements).

Organizing workshops in the initial phase of the process also allows for a quick impact from the dev shop's side.

Taking ownership - a crucial quality of a top custom software development company

A graph showing how willing top software development companies are to take ownership.

A team with a high ownership attitude is not afraid to take full responsibility and own their mistakes because they know how to fix them. Taking ownership means being responsible for their part of the job and going through with it.

These development teams consist of the confident, experienced developers who are focused on looking for solutions.

Why that's important?

  • Developers in that kind of team will work more transparently and will be more creative.
  • The communication with you as a client will be open and close.
  • You will be sure that any mistake will be fixed and potential problems will be openly shared with you.

Being a highly engaged partner

A graph that compares how top software development companies form partnerships with their clients.

A true partnership means becoming a part of your team and being highly engaged in working towards achieving your business goals in the most efficient way.

Why that's important?

  • In traditional outsourcing a task is delegated to an external partner and they just deliver. You can't be sure if everything is going in the right direction. Development teams that form close relationships with their clients transparently share with you their progress. You can keep the finger on the pulse and be sure of the results.
  • In the case of team augmentation, your team and an external team will collaborate more effectively and gain more satisfaction.
  • Engaged teams focus on acieving their clients business goals.

Your next moves

Now, you can continue the research using other resources and sites like Clutch or The Manifest, or already start reaching out to the choses companies.

During the assessment phase, pay attention to culture fit, mutual understanding, and the flow between you and the vendor’s team.

Before starting the cooperation, remember that you should be the owner of the source code, and that needs to be stated in the agreement.

If you want to speed things up, prepare at least a short version of an RFP with all the crucial details. This will save your time as you won't have to write a long e-mail for each vendor.

Good luck!

FAQ - Choosing a custom software development agency

What is custom software development?

Custom software development is the process of designing, creating, deploying, and maintaining software specifically tailored to meet the unique requirements and preferences of an individual, organization, or a specific set of users. This process stands in contrast to commercial off-the-shelf software (COTS), which is developed for a broad market and does not cater to individual-specific needs.

What are the benefits of custom software development?

  1. Tailored solution: Custom software is designed to meet the unique needs of your business, ensuring a perfect fit for your processes, workflows, and objectives.
  2. Scalability: Custom software can grow with your business, accommodating new requirements and changes without the limitations often found in off-the-shelf solutions.
  3. Competitive advantage: By having software that is unique to your business, you can gain a competitive edge through improved performance, innovation, or unique features that are not available in standard software.
  4. Improved security: Custom software can be more secure than standard solutions, as it's less likely to be a target for mass attacks and can be equipped with bespoke security features.
  5. Long-term cost effectiveness: Although the initial investment is higher, custom software can be more cost-effective in the long run, especially if it significantly improves efficiency or replaces multiple off-the-shelf products.

How much does custom development cost?

The cost of custom software development can vary widely based on a range of factors. It's challenging to provide a precise figure without specific details about the project, but I can outline the key elements that influence the cost:

  1. Complexity and scope of the project:
  2. Simple projects (like a basic web application or a simple mobile app) may cost from a few thousand to tens of thousands of dollars.
  3. More complex projects (like an enterprise-level application, a sophisticated mobile app with advanced features, or a comprehensive e-commerce platform) can cost from tens of thousands to hundreds of thousands of dollars.
  4. Highly complex projects (like custom CRM systems, complex integrations with existing systems, or advanced AI solutions) can exceed a million dollars.
  5. Technology stack:
  6. The choice of technologies (programming languages, frameworks, databases) can impact the cost. Some technologies may require more specialized skills, which can be more expensive.
  7. Development team's location and structure:
  8. Geographic location: Custom software development agencies in North America and Western Europe typically charge higher rates than those in Eastern Europe, Asia, or Latin America.
  9. In-House vs. outsourcing: Hiring an in-house team is usually more expensive than outsourcing to a development company or freelancers, considering the added costs of employment benefits, office space, etc.
  10. Design customization and User Experience:
  11. Custom design with a focus on user experience and unique branding elements can increase the cost.
  12. Integration with other systems:
  13. Integration with existing systems, third-party services, or APIs can add complexity and cost.
  14. Data migration and processing:
  15. Migrating existing data into a new system and ensuring its integrity can be a complex and costly process.
  16. Security and compliance:
  17. Implementing advanced security measures and ensuring compliance with regulations like GDPR, HIPAA, etc., can increase the cost.
  18. Maintenance and support:
  19. Ongoing maintenance, updates, and support services are typically charged separately and can be a significant part of the overall cost over time.
  20. Project duration and development methodology:
  21. Longer project timelines and methodologies like Agile software development (which may involve more frequent changes and iterations) can influence the overall cost.
  22. Additional features:
  23. Features like artificial intelligence, machine learning, IoT integration, high-end graphics, or real-time data processing can significantly increase the cost.

How long does it take to build a custom software?

On average, a moderately complex custom software project might take anywhere from 6 to 12 months. However, this is a very rough estimate, and actual timeframes can be shorter or much longer based on the specific project requirements.

The time required to build custom software can vary widely depending on several factors:

  1. Complexity of the software: Simple applications might take a few months, while complex enterprise-level systems could take years.
  2. Scope and scale of the project: The number of features, integrations, and the scale at which the software is expected to operate greatly impact the development time.
  3. Development process: Agile methodologies might speed up the process through iterative development, whereas traditional models like Waterfall can be more time-consuming.
  4. Quality of the development team: Experienced developers and efficient project management can significantly reduce development time.
