The spirit of Pixelfield

Working worldwide

We are proudly working all around Europe and the US. We can get our designers and developers to your conference room in just a few hours, should the circumstances require it. Just ask our happy clients from the Netherlands, Belgium, Denmark, Italy or Switzerland.

Truly agile

Business and digital business especially is a constant adaptation to change. We help our partners to react to changes and needs of the market by being agile, lean and flexible.

Honest and open

We believe that open communication is the only way to success. That's why we always tell you what we think and alert you whenever there might be a problem. Our process is built to be as transparent as possible from pricing to launch.

Hungry for innovation

We plan, create and grow digital products. We help our clients succeed by delivering products that improve life, work and play. We love finding simple solutions to complex challenges and place a strong emphasis on craft in every detail from design to code.

Perfectionist

Every detail matters. From design to code, we keep an eye on every small aspect of the project that might decide whether it will be successful or not. We promote the ways of work we believe bring the best results even if they take time.

Friendly

We cherish and cultivate long-term partnerships with our results-driven mindset and business-first approach. Our mission is to become your favourite tech partners and see you exceed all your business objectives in the long run.

Leadership

We've been around for over 13 years. We combine experience from building UK's leading scale-ups, navigating fundraising and exit to innovating with AI and rapid product development.

You don't get delegated to someone junior. You're working with people who have been there, done that.

Our Journey

2013

Foundation and web

Filip and Michal started the company during their university studies, creating small, simple websites mostly for fun. Pixelfield grew quickly and became one of the best agencies for web and design.

2015

Building mobile apps

We plugged in mobile apps into our focus and started building native and mobile apps and interfaces. App design and development became one of our main focus areas and we have been building award-winning apps since.

2017

Focusing on product and data

Building an app is great, but to have a successful product, decisions need to be based on data and informed product decisions. We started to focus on not just building digital products, but also building based on design and business thinking with clear impact and goals.

2019

Opening in London

We opened our new office in London! Since then, we have shifted our focus to mainly UK-based clients and London has become our HQ and home.

2021

Blockchain, IoT and emerging tech

We started taking on more and more ambitious projects and challenges. Our web and mobile projects are now benefiting from IoT and blockchain integrations.

2023

AI and Automation

Exciting year when AI started to make the biggest impact in our industry. We were able to speed up our delivery by 50%–80% based on the project type, and AI-driven delivery has become a new standard for us.

2026

Today

Building new products and innovating existing products with rapid AI-driven process. Helping businesses to automate their processes with AI and agentic automations.

Are we the right partner for you?

Let's collaborate if:
You need to deliver a scalable product
You need a partner that will push back on you if needed
You have a vested interest in what happens after launch
You have time to make decisions
You care more about doing something right than doing something fast
Let's not collaborate if:
You're optimizing for only price
You're buying hours, not outcomes
You need someone who can take the spec and run with it
You don't have time for iteration
You do not want to hear honest feedback
