Most early-stage startups don't need a full-time CTO. They need someone who's been in the trenches — who can spot the difference between a technical decision that saves you six months and one that quietly buries you.
That's what a technical Non-Executive Director actually does.
I've spent years engineering hardware and embedded systems products from first concept through to compliance and manufacture. What I've learned is that the hardest problems startups face aren't usually technical — they're decisions made without technical grounding.
The patterns I see repeatedly
Choosing the wrong microcontroller because it looked cheaper. Underestimating firmware complexity because the demo worked. Hiring a dev team before the architecture was defined. Missing a certification requirement that costs six months and £40k to fix.
These aren't edge cases. They're patterns I see repeatedly.
What a technical NED actually does
A technical NED doesn't sit in your daily standup. They don't write your code. What they do is fundamentally different and, for early-stage companies, often more valuable:
- Challenge your technical assumptions at board level — before they become expensive
- Translate engineering risk into language investors and co-founders can act on
- Help you build a technical team and culture you can scale
- Ask the questions your developers are sometimes afraid to raise
- Give you a credible, experienced voice when you're pitching to partners or raising a round
The startups that move fastest
I work with founders building hardware, embedded, and connected products. Time and again, the startups that move fastest aren't the ones with the biggest budgets — they're the ones with experienced technical guidance shaping their decisions early.
If you're a founder building something physical or deeply technical, ask yourself honestly: who on your board is qualified to challenge your engineering strategy?
If the answer is no one — that's the gap worth closing.
