DCSL Software

DCSL is considered to be one of the leading software development companies in the UK. They’re based in London, with another office in Hampshire. They’ve been around for more than twenty-five years, so they’ve been involved in tech development since things started ramping up around the rise of the internet. They’re also one of the largest software companies in the UK, with more than one hundred employees. If you’re in search of a company that offers a whole host of development services, such as custom software development, mobile app development, and web development, then DCSL Software will have you covered.

What makes DCSL stand out isn’t just their technical prowess but their commitment to working with the client to ensure that they get exactly what they need.

Tivix

Tivix may be based in San Francisco, but they’ve got a big presence in the UK, most notably in London, which is considered to be their European headquarters. They’ve been in operation since 2008, and primarily focus on enterprise, start-up, and midmarket ventures in a wide variety of industries — the main ones they focus on are healthcare, FinTech, non-profits, and government agencies. What makes Tivix stand out from the crowd is that they work quickly; they’re able to provide rapid turnaround to their clients, without any compromises when it comes to quality. They’ve got a wide range of skills in their locker, including UX/UI design, product management, DevOps, and full-stack software engineering.

Recently, they’ve been working on a complex military project, which involved rebuilding a system that provides alerts when submarines in international waters come into problems.

Softwire

Softwire celebrated their twentieth birthday last year, and they show no signs of slowing down anytime soon. They’re based in London and Bristol and have a large team of more than 122 workers. They specialize in areas such as media, education, and non-profits, to whom they’re able to offer a wide range of services, including web development, the development of custom apps, and mobile apps. They stand out from the others in their area because they’re able to provide a full level of service. For example, they can provide website design, build a mobile app, develop custom software for internal use, and also provide ongoing support and maintenance.

Theodo

Theodo hasn’t been around as long as other companies listed on this page, but they’ve certainly made a name for themselves during the six years since they were founded. They’re based in London but they also have a Paris office, too, which is always a sign that a company knows what’s doing. They have more than thirty employees, who are well-versed in a wide range of technical skills, including mobile app development, custom software, and web development.

The skills of Theodo go beyond what they’re able to do from a software point of view, however. They’re known for engaging with their clients, with whom they closely discuss the needs. They’re not just able to deliver the work, but clients often mention the high level of interpersonal skills that they have, too.

Imaginary Cloud

Imaginary Cloud has a relatively small team — fewer than fifty employees — given the size of the company. Though the team may not be as big as other teams, that doesn’t mean that they’re unable to produce outstanding work. What sets them apart is that they’re highly versatile. They’ve got a lot of skills in their toolkit, which allows them to help companies of all sizes. If you’re in need of a company that can help you to design, build, and launch a web or mobile application, then Imaginary Cloud can help with just that — they’ve got ten years of experience in that field. They don’t have a particular industry that they specialize in, but they’ve been known for working with companies in the IT, business, and financial services sectors.

Bjss

There are some famous faces on this list, but it’s unlikely that any will be more famous than Bjss, which is one of the– if not the — leading technology companies in the UK. They’ve been around since 1993, and in that time have gained a reputation for delivering outstanding and innovative work. They’re based in West Yorkshire, but they’ve got a big presence around the UK and indeed, around the world, with offices in London, New York, Houston, Manchester, Bristol, and Cardiff.

They offer all the classic services that you’d expect from a software development company, but what sets Bjss apart is that they’re on the cutting edge of all that’s new and trending. For example, in recent years they’ve been at the forefront of things like Artificial Intelligence and Big Data, two fields that are going to dominate the future. And you can imagine that Bjss will be right at the front of these movements since they have been for most other tech-related things over the past few decades.

eSynergy Solutions

For eSynergy Solutions, it’s all in the name — they come up with solutions. It doesn’t matter what industry you’re in or which problem you’re trying to solve; the team behind the scenes will work to ensure that the final product exceeds the wishes of the client. In recent times, they’ve set themselves apart as one of the leading tech companies in the UK by moving into fields of the future, including cloud computing and data engineering.

They’re based in London and have been in operation since 2001.

TatvaSoft UK

If you’re looking for an all-around software development company that will simply deliver the goods, then TatvaSoft is the company you should be looking at. But you don’t have to take our word for it — you can just look at their credentials. This is a company that is CMMI level 3 and Microsoft Gold certified, and can offer a whole range of services for companies in a host of different sectors. Indeed, the list of services they provide is extensive — they’re specialists in web development, e-commerce, UI, UX, software development, and just about everything else related to tech. The growth of the company is evidenced by its large staff and global presence; they have formed 18 years ago and today have a staff of more than 900 professionals, who are located in the UK, USA, Canada, Australia, and India.

Software Solved

There aren’t too many companies more popular than Software Solved. They’ve gained a reputation as being the go-to company of Fortune 500 Companies over the past two decades they’ve been operating. They specialize in data and custom software, and have a few special areas of interest — they’re highly effective when it comes to things like logistics and warehouse management, for instance, as well as professional services.

What makes them an attractive prospect for clients is that they offer end-to-end support. They’re involved every step of the way, from the beginning consultancy stage to the design and development, to after-project care and support. This makes them appealing to companies that are less experienced with technology and software.

Objectivity LTD

If a company has been around for some thirty years and boasts a team of 600 employees, then they must be doing something right. And certainly, Objectivity has been doing many things right. They’re headquartered in Coventry and are experts when it comes to developing custom software for companies, especially those in the financial services, business services, and real estate industries. The underlying goal of the company is to help other companies work more efficiently; this is the guiding principle that has ensured that they’ve got a long line of happy customers, and which suggests that they’ll continue to have as much success in the future as they’ve done in the past.

They’re a large, multiskilled organization that can provide any number of tech development support, including web development, software development, software integration, and also generally IT consulting. They’re especially skilled when it comes to things related to e-commerce, especially since they’re considered leaders in the understanding and implementation of Magento, WordPress, and Drupal. While they’re able to offer a full-service to their clients, this is anything but an off-the-shelf approach. They work with the company to ensure that all the tech that’s developed is in line with the company’s branding.

Seb Azzo

Seb Azzo is a company that proves that you don’t have to be large to be mighty. They’ve been around since 2012, yet they still have the feel of a company that is just getting started — and we mean that as a compliment. Their team is only around ten people, and in the nine years or so since they’ve been in operation, they’ve helped companies with custom software development and enterprise apps. They’ve got a pretty large and diverse client base, working with start-ups to large organizations. Their specialist industries are education, hospitality, and business services. What attracts businesses to Seb Azzo is that they’re able to combine high-end features with easy customer usability.

DabApps

If you’re looking for a bespoke software development company, then DabApps might be your first and only port of call. They’ve got the look and feel of a company that very much belongs in 2021; they’re cutting edge, they’re young, they know what tech works, and they have the creative tools needed to bring your software to life. They want to make it interesting, essentially. This commitment to delivering this level of quality has ensured that they’ve got a long line of happy customers. What ensures that the client will be happy is that the team brings all their energy and enthusiasm to the project; if it feels as if you’re getting the custom treatment, that’s because you are. They’ve been around since 2010 and they’re still a relatively small band, with fewer than fifty employees, but they’ve proven time and time again that they’ve got all the skills needed to produce excellent work.

Today, they’re recognized as one of the leading companies when it comes to tech consultancy and has even written several books about how companies can further their software. They’re based in London and have worked with development teams in a wide range of companies, including Byron Hamburgers and Associated British Foods.

Momentum

Momentum is all about creating an excellent, human-focused digital experience. They work with companies in a wide range of sectors, including healthcare, consumer products, technology, and financial services, to name just a handful. They’re well-versed in all the main programming languages, but they’re also at the cutting edge, too. For example, in recent times they’ve worked on projects related to Blockchain, artificial intelligence, and the internet of things. Their expertise when it comes to custom software development is seen by the long list of very famous faces that have been clients of Momentum: Facebook, Orange, Morgan Stanley, Walmart, Adobe…the list goes on and on. They’re based in London and have between 10 – 49 members of staff on their team.

Make It Simple

Founded in 2005, Make It Simple is based in Droitwich and has around ten members of staff. They excel in software design and development, but they also work on mobile app development too. The companies they tend to work with come from small business and midmarket backgrounds. What makes Make It Simple a joy to work with is their understanding of the companies that they work with; they’re not just there to provide the technical skills, but to make those skills work with the particular client in mind. While the client is free to provide as much input as they like, the team is also happy to just get on with the work, always working with the timeline in mind.

Anuitex

They’ve been around for nearly ten years and in that time have grown to become a team of more than 150 employees. They offer a whole range of software solutions for businesses, including ones related to the web, mobile, and the cloud. Their clients are diverse, and can be small, midmarket, or large businesses — in general, their main industries are education, finance, and healthcare. What makes them stand out is that they’re proactive and can offer clients advice and recommendations from the very beginning of the development process.

CSI Media

CSI Media has won plenty of rave reviews from happy clients since their formation 22 years ago. What makes them such a hit with their clients is that they’re able to bring both modern and inspiring design and the latest technological innovations to their projects.

Clock Limited

Any company that has been around since 1997 must be doing something right, and if there’s a company that’s doing something right, it’s Clock Limited. With a team of more than thirty people, they’re able to offer companies custom software, as well as web and mobile app development. While there are plenty of companies that have technical skills, what makes Clock Limited different from the other companies out there is their openness to hearing ideas from their clients. Indeed, past clients have said that they were highly open and receptive to any comments or suggestions that were made — and that’s just what you need when you’re developing custom software.

Entropy

Based in Bletchley and founded in 2013, Entropy is a team of around ten members of staff, and specialize in custom software development and mobile app development, among others. They tend to work with companies that work within the media, education, and healthcare fields. They’re especially popular with companies that have the requirement for high-quality digital presence, but which don’t have much experience in that field, since they can guide the company through things from beginning to end.

Isotoma

This firm, founded in York in 2004, has a team of more than twenty employees that specialize in custom software development and UX/UI development, among other services. They focus generally on the midmarket and small business ventures and have experience in coming up with solutions to unique problems.

Founded in 2007 and based in London and Surrey, Plug & Play is an agency that specializes in user interface design and the user experience.
