About Skillwork

Skillwork was born in 2019 in London in a university lecture theatre during our final year of studies. Coming from the start-up environment, we’ve embarked on a mission to design a team that would excel at building great products for UK-based start-ups and scale-ups. This required putting together a multidisciplinary group of talented people, from engineers to business experts, who would be able to support the founders across all domains of their organisations.

From the very beginning, we have employed a start-up mindset and start-up-like culture as a source of our competitive advantage. Our vision is to marry the slow but robust enterprise approach to software development, with a truly agile start-up mindset, to create a powerful methodology for innovating with organisations of all sizes.

As founders, we went through a rollercoaster of hyper-growth and slowdowns in demand over the past years. We have had big wins but also made mistakes. Nevertheless, no matter the market conditions, we have been refusing to stagnate as an organisation and as professionals. We believe that a ‘natural’ state is to consistently grow, learn, and improve, and we are building a community for those who share this mindset.

In our team, we promote proactiveness, transparency, and a ‘fail fast’ mentality. We want to create an environment where you are empowered to grow, experiment, ask questions, and be challenged, finding solving issues exciting and fulfilling. We also think that people like to work with those they enjoy being around, and we are a very friendly bunch. We keep our work professional but we like to joke and laugh whenever we can. Relationships are at the heart of everything we do.

Finally, we aspire to develop our very own innovations and products soon. We have big dreams and want to create a truly exceptional organisation that we can all be proud of. Skillwork is still young but we have all the tools we need to our vision come to fruition – and you are now a part of this crazy journey!
