Use our tech to win the internet. It's free.

Teemill enables values-based organisations to increase engagement and awareness with campaign t-shirt designs. Campaign tees are exciting products with meaningful messages that are super shareable and mobile-friendly Teemill stores are purpose-built to help you win the internet.

We are a pioneering sustainable business that only uses organic materials and renewable energy powered factories. We provide campaign t-shirt store systems and fulfilment to help campaigns and good causes for free.

Our dedicated campaigns team help organisations reach national audiences. Our expertise in viral t-shirt campaigns raised over £1m in fundraising revenues for registered charities in the first year of Teemill’s public launch alone.

We’re a young, energetic, technology-focused supplier and we’d love to talk to your organisation about how Teemill can help you engage with your message through fashion and take your campaign to the next level.

t-shirt supply chain

Teemill products are printed in the UK using low-waste printing technology in a renewable energy powered factory. All our products (t-shirts, jumpers, hoodies and more) are made from certified organic cotton by ethically accredited suppliers. As a company, our Global Organic Textile Standard certification means that we've been audited for a wide range of sustainability and social criteria throughout the product life cycle.

Our mission is to redesign the clothing industry.

Teemill was created to accelerate the transition to more sustainable clothing by removing the barriers to entry for charities, events or startups in fashion that want to be part of the solution, not part of the problem. Creating enabling technology has led to growth, whilst improvements are shared by all users. Redesigning the t-shirt industry has created a virtuous circle that is accelerating. This story is your story too. When you use Teemill, anyone can follow the journey of your t-shirts from seed to shop...
