British Design Fund


The British Design Fund (The “Fund”) supports enterprise and innovation in the UK by investing in, supporting and mentoring, early stage, well designed, product businesses.  The Fund works with extraordinary entrepreneurs with scalable products who are ready to accelerate growth and build long term value and thriving stand-out businesses.

The Fund only works with British companies that have designed physical products to address a clear user need and which solve real problems.

"Its great to have a fund that really knows design, knows products and has been there before and faced many of the challenges we will face."

Tim Antos, CEO, Kokoon Technology

Investment focus

Currently there are few funding mechanisms specifically dedicated to early stage product businesses.  The British Design Fund believes that these early stage product businesses need not just capital but also mentoring and expertise along the way to ensure they grow into successful companies.

The British Design Fund seeks to work with extraordinary entrepreneurs, with innovative and scalable products, who are ready to accelerate growth and build long term value and thriving stand-out businesses.

Along with the cash investment, which is made in exchange for an equity stake in the business, the British Design Fund can also provide support and mentoring across key areas such as sales, marketing, international distribution, IP, legal, licensing and contracts, financial planning, stock control, design management and manufacturing.

The British Design Fund is managed by Sapphire Capital Partners LLP, who are authorised and regulated by the Financial Conduct Authority with firm reference number 565716. Twenty20 Mentoring provide the market expertise to identify and accelerate the growth of each investee company. Twenty20 Mentoring Limited is not a FCA authorised firm and will not be providing any investment services or undertaking any regulated activities in connection with the Fund.
