Unmade is a global fashion software company driving innovation through customisation and delivering an end-to-end digital solution for on-demand production at scale. Started by Hal Watts, Kirsty Emery-Laws and Ben Alun-Jones in 2014, the company was born out of a desire to reimagine both the design and manufacturing processes within the fashion industry, so brands only make what is actually sold, resulting in minimal waste. It then officially launched as Unmade in 2015, having previously been called Knyttan.

We were nominated for the LVMH Innovation Award at VivaTech in Paris, and in 2017, we won the Best Use of Innovation at the Drapers Digital Awards in London.

Furthermore, Unmade was named as one of the 100 best creatively led businesses in the UK by The Creative Industry Council, and in May 2018, it completed the Lafayette Plug and Play program as part of the renowned Plug and Play innovation accelerator. Pieces from Unmade are now a part of the permanent collections at both the The Museum of Modern Art in New York and the Victoria & Albert Museum in London. Most recently, Unmade has been named no 41 in Fast Company’s 50 for designing a less wasteful fashion industry, alongside brands such as Apple, Universal Music Group and Shopify. Also included as number 2 in the style category.

We work with 4 out of the 25 largest groups in the fashion industry, and in addition we have clients like Christopher Raeburn, Rapha, Moniker, and a number of other international fashion brands, which work with us to give their customers the option to customise the products they want.

We are a team of 30 people working across Engineering, Design & Product, Sales & Marketing, Customer Success, and Operations, and are based at Somerset House, one of London's most important and exciting cultural landmarks.

What’s it like working at Unmade?

  • We are doing work we care about, and we are supportive of others to do the same.
  • We have fostered a culture of collaboration and we believe in exchanging information and learning from each other - no one is unapproachable, and everyone’s ideas matter.
  • We believe that potential is more important than experience, and hire accordingly. Don’t worry if you don’t have all the skills and experience we’re looking for today - apply anyway! In fact, many of our colleagues started here with little experience and learnt on the job.
  • We believe that what you build is just as important as how you build it, and that technology is just as much about people as it is about code. We are building a product where people with little to no technology experience can be involved in an element of the creative process, and are constantly thinking of ways to make it better and more seamless.
  • We strive to be transparent in everything we do, and share both our successes and failures with the rest of the team. As a result, we’re comfortable that even if things don’t always go as planned, we are always doing our best.
