Head Of Growth, Japan (Series C Healthtech)

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 company 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, dietitians, 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.

Since launching, we've grown fast to support millions of patients. We launched in Japan in 2024 and quickly shifted some focus to support our fast-growing UK business. Since then, Japan has shown strong momentum, growing over 150% and expanding our marketing investment tenfold. Our goal is to reach 50,000 patients by the end of 2026, building on the success of our UK team, which grew from 5,000 to 40,000 patients in just ten months.

Globally, Eucalyptus now generates over A$500M in annual revenue and continues to double in size each year while staying financially sustainable. We've also made sure our people share in that success — around 20% of employees have already benefited from our employee share program.

Our mission through Juniper is to empower people across Japan to take control of their weight journey. For us, this means a medical approach to weight loss that doesn't judge, doesn't discriminate, and really works! It's why we connect patients with Japanese doctors, dietitians and a clinical team, who can guide and empower them on their journeys. With clinically proven medication, lifestyle interventions, ongoing support, and a community of like-minded women, we help patients achieve better weight loss outcomes.

If this gets you excited, let's talk.
