About British Design Fund

The British Design Fund backs enterprises and innovation across the UK’s engineering and manufacturing sectors. The fund’s aim is to help these businesses scale their products, accelerate growth, and build long-term value. Each portfolio company is purpose-led and addresses a meaningful challenge within its sector.

Founded in 2016 by Damon Bonser, BDF Advisors has been supporting entrepreneurs for the past nine years. Damon is a serial entrepreneur with over 20 years’ experience building and running product development and manufacturing businesses.

The Challenge

In 2016, BDF Advisors set out to establish a fund vehicle that could operate under both SEIS and EIS structures. To do so, they needed an FCA-authorised investment manager who could assume regulatory responsibilities, allowing BDF Advisors to focus on the non-regulated aspects of mentoring and supporting the fund’s investee companies.

The Solution

BDF Advisors partnered with Sapphire as the fund’s FCA-authorised investment manager. This enabled the successful launch of the first British Design Fund and marked its formal inception. Building on this foundation, British Design Fund Two and British Design Fund Three were launched in 2020, with the second fund focusing on the design sector and the third on early-stage, design-led businesses.

The decision to work with Sapphire was driven by Sapphire’s experience in launching and managing SEIS and EIS funds. Our understanding of investment management and compliance obligations gave BDF Advisors the confidence to continue working with Sapphire as investment manager, enabling BDF Advisors to remain focused on investee company due diligence and mentoring.

“They [Sapphire] have proven to be the right partner for us, and it is a pleasure to work with them.”

The Results

This ongoing collaboration has supported the launch of three further funds: British Design Fund Four and British Design Fund Five in 2022, and the British Design Evergreen SEIS & EIS Fund in 2024. The Evergreen fund is focused on investing in purpose-led product and engineering start-ups, helping them grow and progress to the next stage of their development.

Together, BDF Advisors and Sapphire have demonstrated that with consistent, high-quality execution and clear communication, the fund launch process can be managed efficiently and scaled over time.
