Why choose
machine learning?

Why choose machine learning?

Machine learning is no longer “nice to have.” Its extraordinary spread and growing ubiquity mean that businesses risk losing out to more innovative competitors if they fail to harness its potential.

From augmenting human creativity to reaching new levels of efficiency, a tailor-made machine learning solution developed by our in-house experts will help you reach your business goals.

With STX Next, you can develop an application in any artificial intelligence area, including, but not limited to, statistical modeling, classification, regression, clustering, anomaly detection, association rules, computer vision, natural language processing, speech recognition, chatbot, and recommendation systems.

Our machine learning services are complemented by end-to-end product design and world-class software development, allowing you to build your product with us from the initial concept up to launch.

We are the largest Python software house in Europe

—maybe even the whole world, and Python is the best-suited programming language for machine learning

Due to its versatility, flexibility, and comprehensiveness, Python is the perfect fit for machine learning solutions.

The language's open-source and high-level nature as well as its numerous libraries provide the necessary tools for anyone working with the technology, whether it’s reinforcement, supervised or unsupervised machine learning problems they’re dealing with.

We’ve placed a special emphasis on Python since we were founded in 2005. Today, we have 200+ Python developers on board, which makes us the largest Python software house in Europe.

Our machine learning experts are not only skilled in the technology—they all boast extensive Python experience, too.

Machine Learning - outsourcing

What if I want to keep some of the work in-house?

Smart move. By all means keep your existing team if it works for you. Your external team will simply complement what you’re already doing while bringing in a fresh perspective and greater scalability.

They’re embedded completely in our process to the point that there’s no difference between one of our in-house developers and one of theirs.
Software Engineering Manager

What if I need to save my budget and cut development costs?

You can scale the team down or move development entirely back in-house.

Not only are they transparent and flexible, but they’ve been immensely helpful when we needed to scale up. When the time came to scale down, it was no problem, either.
Blocktrade AG

How will I know you’re a culture fit?

We’ve been on the market since 2005 and 99% of our clients are outside of Poland, so we have lots of experience cooperating across cultures.

STX Next has very energetic and sociable teams, and we get along well. After working extensively with their teams, we honestly see them as colleagues rather than suppliers. That’s a unique thing, and it has to do with the culture of STX—it’s something they should be proud of.
Hogarth Worldwide
CTO / Product Director

How can I be sure you’ll understand my project and what it needs?

You don’t want to just ship features; your software should help your business succeed in the market. That’s why we’ll begin our cooperation with a discovery process to understand what you’re building, for whom, and why.

They are willing to learn and understand our business. Instead of just coding to our specs, STX Next engages with us as a partner, wanting to understand, improve the code, and deliver better products.

STX Next have been working really well with my engineering team. They’re demonstrating great skill, craft, and agile thinking in the way they go about their work, and they’re great people to boot.

Kim Steglich
Director of Operations @ BuildFax

Working with STX Next felt like a strategic partnership rather than outsourcing. From consultation through to development and delivery, the STX Next team integrated seamlessly within our own team, in a challenging technical area, and delivered to the same standards we expect from our internal developers.

Michael Stone
Chief Technology Officer @ Enroly

It was always a team that showed initiative, not just receiving instructions to deliver features but also asking why and what we were building so that it quickly became much more collaborative.

Mark McLaughlin

We were able to scale up instantly, adding developers with the specific technical expertise that we needed and then rotating them out when the problem had been solved. At a much smaller firm that would have been very difficult. So far there hasn’t been any challenge that STX Next hasn’t been able to overcome.

Matthew Brooke-Hitching

We met STX in the beginning of the latest cryptocurrency boom and their contribution was vital to us when managing that extraordinary demand. They quickly adapt to the company and domain, show true ownership by always acting proactively towards solution and deliver high quality work even under stressful conditions. STX is now one of the most essential partners of our business.

Çağatay Yüksel
Founder and CEO @ Koinim

They have a genuine interest in their client’s business environment. Their Scrum teams were more like an extension of our own team than an external entity. They don’t force a template on their client, focusing instead on delivering software in a way that compliments the client’s own process. Our work together resulted in award-winning products that we would not have otherwise delivered.

Apart from their quality of work and timeliness, it was important for us to have clear communication. STX Next met this expectation very well.

The STX Next team has proven itself to be a solid and reliable partner in software development for the Tiqets platform. Although Tiqets’ main development team is located in the Amsterdam office, having dedicated development teams in Poland gives the company the flexibility it requires in the rapidly growing market that Tiqets operates in.
