Team & culture

People before technology

Engineering excellence, long-term thinking, responsible innovation and practical execution. SFN is built by founders who have done it before — at every layer of the stack.

The team

Who we are

David Summerland
Founder & CEO
David Summerland

An industrialist with 35 years of experience across software, embedded electronics, entertainment lighting, fabless semiconductors, and semiconductor manufacturing technology. His pattern across five founded companies is consistent: identify a constraint the industry treats as permanent, determine whether it is physics or process, and remove it — rebuilding at a deeper layer of the stack each time.

Prior companies include MAD Lighting — built from a garage to £7M turnover with a successful exit — and Verdi Semiconductors, a fabless LED company that attracted a PwC-led M&A process. SFN's IP estate spans 114 granted and pending patents — 68 granted — across 17 invention families in 24 territories, with 18 registered trademarks.

As Co-Founder and COO of Search For The Next, Sam is also engaged with the strategic and commercial dimensions of the company's development.

Culture

How we work

Engineering excellence

Evidence over claims. Demonstrations over promises. Every capability statement on this site is demonstrable at our development facility today.

Long-term thinking

Building the system that creates the next generation — not optimising the current one. The Self-Learning Loop compounds improvement over time by design.

Responsible innovation

Human direction at every step of the loop. The gate is not a feature — it is the architecture. AI proposes; humans authorise; fabrication follows.
