Head of Growth, Japan (Series C HealthTech)

🌿 About Eucalyptus (Euc)

Good health, for life.

More than one billion people worldwide live with obesity — a key driver of preventable chronic conditions like diabetes and heart disease.

Eucalyptus is the digital healthcare company behind Juniper, one of the world’s largest weight-management programs combining:

• clinically proven GLP-1 medication

• personalised nutrition + movement

• support from doctors, dietitians, coaches and pharmacists

Our published research shows that Juniper patients lose 4x more weight when combining medication with lifestyle support, compared to medication alone.

By 2026, we will support 1 million patients globally.

🇯🇵 Eucalyptus in Japan

Launched in 2024, we have already grown to ~1,000 Japanese patients. By partnering with medical institutions and government bodies, we aim to support 50,000 patients per month by 2026.

Our track record:
In the UK, we scaled from 2,000 → 70,000 patients in just 18 months.

Backed by $200M+ USD in funding and triple-digit annual growth, we are building a long-term, clinically responsible healthcare model trusted by patients and doctors worldwide.

🇯🇵 Why Japan?

Obesity in Japan often goes unnoticed. While Japan is seen as a “slim nation,” the WHO defines obesity in Asian populations from BMI 25, due to increased risk of diabetes and heart disease at lower BMI levels.

Every year, 20% of adults in Japan are informed of obesity indicators during health checks — yet few receive sustainable support.

Meanwhile, GLP-1 medications are frequently used by beauty clinics for patients who may already be within a healthy weight range.

Eucalyptus exists to bring:

• clinical precision

• ethical prescribing

• affordable access

• zero shame, zero judgement care

Our mission is simple:
Help people enjoy the next 30–40 years of life with true health, vitality, and confidence.
