Client feedback

"I give my highest recommendation to anyone considering working with Dr Sacher. For the past several years we worked together day-to-day, studying and building digital weight management software and programs. Dr Sacher has been an inspirational colleague, generously sharing his extensive knowledge of behavioural science and academic research in the weight management space. Dr Sacher is also a true thought leader, playing an instrumental role in defining how we could best bring the power of AI effectively and safely to our products. He will bring huge value to any organization that is lucky enough to have his time. I fully expect to work again with Paul in the future and hope that it is soon."

"Dr Sacher is one of the most talented and driven experts in nutrition, behavioural medicine, and lifestyle modification in the field today. A widely published scientist in his own right, he has a great command of a highly dynamic research field that is changing by the day. He is also a thoughtful and kind leader who knows how to assemble teams that march toward the same goal. It was a pleasure working with him to build the best-in-class program we have at Allurion today."

"I highly recommend Dr Sacher for any organisation seeking to elevate the science behind their value proposition and transform long-term patient satisfaction. As the VP of Behavioural Science at Allurion, Paul has proven himself to be an invaluable asset.
From the moment we hired Paul, it was clear that his wealth of experience in behaviour change, weight loss, and data science would greatly benefit our organisation, healthcare providers and patients. His transformative work in creating our behaviour change program, delivered via an app to our patients, has had astonishing results. Our patients have been able to sustain 95% of their weight loss even 12 months after the program's end, which is truly an impressive metric considering the chronic nature of obesity.Paul's expertise has been instrumental in this achievement. However, it is his collaboration skills and exceptional customer acumen that truly set him apart. Together, we have traveled the world, allowing him to meet hundreds of surgeons and customise our program and tools to meet the needs of healthcare professionals. His ability to connect with customers and understand their unique perspectives has been crucial to our success. Overall, Paul's contributions have elevated the science behind Allurion's value proposition and transformed patient satisfaction in the long term. I have no doubt that he would be a tremendous asset to any organisation looking to make a lasting impact in the field of healthcare."

Chief Commercial Officer, Allurion Technologies

"Dr Sacher is the rare expert who combines a deep understanding of the latest academic research with a knack for crafting impactful digital experiences. He seamlessly blends the most recent insights and research from behavioral science with a digital mindset. Smart, patient, and empathetic, he played a pivotal role in building and launching Coach Iris, our AI Weight Loss coach.
His expertise defined the strategy, evaluation and coaching approach, ensuring Coach Iris delivers meaningful, accurate and safe guidance for our weight loss patients. Any healthcare company aiming to enhance or launch a science-backed behavior change program, supported by AI and robust data analytics, would be fortunate to have Paul as a leader."

Joe Ranft

VP Digital Product, Allurion Technologies

"I had the distinct pleasure of working with Dr. Sacher at Allurion Technologies. During this time, Dr. Sacher provided insightful, data driven, Behavioral Science-based subject matter expertise for Allurion's patients and providers during their weight loss journey. His impact on the development of our predictive AI model (Success Predictor) helped providers identify patients who were at risk of not achieving their weight loss goals, leading to earlier intervention. And for patients who were on track (to achieve their goals), the Success Predictor reinforced good behavior, again relying on Dr. Sacher's background in Behavioral Science. Furthermore, Dr. Sacher played a key role in developing Coach Iris, Allurion's ChatGPT virtual coach, including the strategy, prompt engineering, quality assurance, safety monitoring and liaising with providers in response to clinical concerns, and the evaluation and interpretation of the performance metrics. Beyond being an expert in Behavioral Science, Dr. Sacher was a trusted resource in collaborating with members of my (software development) team, working closely with data engineering, data science, design, mobile app and web teams. I highly recommend Dr. Sacher for any role where his vast knowledge of Behavioral Science can be applied in a collaborative and data-driven manner. I look forward to seeing the details of his next successful venture."
