Head of Growth, Japan (Series C HealthTech)

🌿About Euc

‍

We’re making good health last a lifetime

More than 1 billion people globally live with obesity - a major leading indicator of many preventable chronic diseases such as diabetes and heart disease.

Eucalyptus is the digital healthcare scaleup behind “Juniper”, one of the world’s largest weight management programs combining GLP-1 medication with a tailored nutrition and exercise programme, supported by our multidisciplinary care team of prescribers, health coaches, dieticians, nurses and pharmacists.

Our published clinical research demonstrates that our combined approach to weight management and lifestyle change means that our patients are 4x as likely to lose significant weight through their course of treatment with Juniper than with the medication alone.

In 2026, we will support 1 million patients globally

Eucalyptus launched into Japan in 2024, and have grown to ~1,000 patients with a plan to partner with medical institutions and governments to help 50,000 patients every month, by the end of 2026. We have the track record to do so, having grown our patient base in the UK from just 2,000 patients to nearly 70,000 over the past 18 months.

We've raised over $200M US in funding, growing triple digits every year for the past 3 years while building a financially sustainable business that will support patients for decades to come. These signals are a result of the trust our doctors, and patients, place in the Juniper program to help them drive lifelong change and overcome obesity.

Why Japan?

Obesity is a problem (disease) hiding in plain sight in Japan. The global narrative around Japan being one of the world’s slimmest nations, is often misleading with the World Health Organisation recognising obesity in Asian patients at a BMI of 25, rather than 30 (the standard used for Caucasians). The reason for this is that Asian patients are more likely to develop chronic diseases such as diabetes and cardiovascular disease at lower BMI levels.

20% of Japanese patients every year are being informed of their obesity BMI indication, in annual health checks, but very few are able to complete a sustainable treatment plan. Beauty clinics in Japan have put these medications into the hands of patients who are already within a healthy weight range, and oftentimes underweight. Eucalyptus is here to ensure that the patients who genuinely need these medications are aware, able to afford, and access these medications conveniently, after a lifetime of shame and judgement from society.

Nobody should have to feel ashamed, or impaired by living with obesity. We are all living for longer, but not necessarily better. If we successfully achieve our mission, we have a once in a generation opportunity to fundamentally improve how much people are able to enjoy the last 30-40 years of their life. We don’t think there’s another mission more worth of your time.

You are able to think critically, and break down big goals into smaller workstreams to empower others to act.

When metrics are ahead of track, you seek to understand whether it can be replicated across the business before celebrating the win.
• Calm, collected and resilient: You thrive in a fast-paced, chaotic, startup environment where you will need to balance quality with velocity and a MVP mindset.
