Greater than the sum

Aged just 37, doctors told my sister to give up. Rosie’s chronic fatigue had already taken her job, her independence, whole stretches of time she still cannot account for. The advice from the NHS was not medical, it was procedural: apply for benefits, get on the council housing list, come to terms with the fact that this was her life now. Just give up. We didn’t. Zoom out, and this is a familiar shape in health and biotech founder stories: the moment the science clicked, the sensor that shouldn’t work, the trial result nobody expected.

We tell those stories because they are the easy part to tell. What we talk about far less is what actually carries an idea like that out of a lab, or in our case out of a family crisis, and into a company people trust with something as personal as their health. I have built two businesses at that intersection now, and both taught me the same thing from different directions. The idea is rarely the constraint. What decides everything is whether the people around it actually believe in what they are building, enough to keep believing when the data disappoints, the funding slips, or the science simply does not cooperate. Holding it together under pressure is the minimum bar. What you actually need is belief that survives contact with reality, the grit and resilience to stay in it for years rather than months, and the integrity to get there without cutting corners on the people you set out to serve.

Conviction before the proof exists 
In 2014 I founded Zedsen, we had sensors that could read what was happening inside the body without a needle or a scan. John Sculley, who ran Apple and Pepsi, mentored me while the technology was still unproven. Not because the data existed yet but because of the vision and the conviction of the people building it. One of the most experienced operators I have ever met bet on the people before he bet on the roadmap. I saw the same pattern again, closer to home, at Naya Health. Professor Alexander Sack is one of the most respected names in neuromodulation research anywhere in the world. He joined us before we had opened a clinic room, before we had treated a patient, before there was any proof our model would work. He joined because of the vision we described to him. Conviction, not evidence. If the only people you can attract need the proof first, you are probably not describing the vision clearly enough. 

Purpose first, red lines second
Rosie is the reason those red lines exist. My wife and co-founder, Emily Honeywell, is an investor and serial entrepreneur in health and wellness in her own right, and leads brand and patient experience at Naya. It was as much her conviction as mine that set the terms for what we’d build. Together we spent a long time at the dinner table discussing the Japanese concept of Ikigai, the intersection of what you love, what you’re good at, what the world needs, and what you can be paid for, working out what we actually wanted to build. Underneath it be had a thick red line with two rules: only work with people we like, and never lose control of the mission.”

They might be the simplest of rules but they are the hardest filter we apply. We turn down commercially attractive opportunities, and brilliant people, if they don’t clear that bar. When things get difficult, and in health they always do, you need total trust in the people either side of you. A CV will not tell you whether someone is still honest with you at 2am after a bad result. We hold the same line on money. We believe in purpose driven businesses, and profitability has to work in service of that purpose and the patients it exists for, not at their expense. If a decision would improve a margin but quietly worsen someone’s experience or their outcome, we do not make it. That’s not a line for a pitch deck – it’s the only way trust survives contact with a P&L.

What purpose means when it’s not a slogan
Rosie was one of our first patients, when the company was barely formed. Her sparkle is back. She’s well on the road to recovery. Internally, we still ask “what Rosie would need” before we ask what the market needs. That question has produced outcomes I still find hard to describe without emotion. A lawyer, bedbound for five years, back at work. An investor, bedbound for a decade, now walking five kilometres a day and about to take his first holiday in ten years. A woman so consumed by anxiety she couldn’t leave her house, who called us in tears to say we’d given her back her spark, then stood up and gave a speech in front of a hundred people at her father’s birthday, the exact goal she’d set when she first came to us. Purpose that specific doesn’t evaporate when a quarter goes badly. Instead, we find it is the reason a bad quarter doesn’t break the team.

Culture is what happens when the science doesn’t cooperate
Every founder hits a version of this, science or not: the trial that stalls, the pilot customer who doesn’t convert (despite you doing everything to make it happen), the model that doesn’t scale the way the deck said it would. Building anything new rewards patience and punishes ego in roughly equal measure, and most cultures aren’t built for that combination. I’ve watched brilliant teams fracture, not because the work failed, but because the failure exposed a culture with no honest way to metabolise it. No room to say that didn’t work without someone’s ego or status taking the hit. The founders I respect most treat a failed experiment and a successful one the same way: as data, reviewed openly, no hunt for someone to blame.

Why the people matter more than the résumé
Healthcare, like most ambitious entrepreneurial journeys, sits at the collision of disciplines that don’t naturally speak the same language. Clinicians think in patient outcomes. Engineers think in iteration speed. Regulators think in risk. Investors think in timelines (and risk!). The companies that become greater than the sum of their parts are the ones where leadership actively translates between those worlds, and where every hire has already cleared the harder test: do we trust this person when it matters, not just when it’s easy.

What I’d tell the founder I was
If I could go back to the day we sat with Rosie’s diagnosis, I would not tell myself to work faster on the science. I’d tell myself to spend more time on who we brought in, at every stage, whether they joined on conviction alone or joined once the proof points started to line up. Expertise is easy to check on a CV. Belief, determination and integrity are not, and they are what actually decide whether a breakthrough becomes a company that lasts, or stays a very good idea that never quite finishes becoming one. The science gives you a chance and an opportunity. Belief, resilience and integrity decide whether you make it. Rosie decided we should take it. So we did.
