Function's New Strategic Hire: Ziad Sultan

In a significant move aimed at elevating healthcare through advanced technology, Function, a pioneering health tech company, has announced the appointment of Ziad Sultan as its Chief Product and Technology Officer (CPTO). Sultan, who previously served as the Senior Vice President of Personalization at Spotify, brings a wealth of expertise in AI and personalized user experiences to Function. This strategic hire comes on the heels of Function’s recent $298 million Series B financing round, boosting its valuation to $2.5 billion.

Function’s mission revolves around utilizing cutting-edge technology to empower individuals to lead healthy lives for up to 100 years. The company is committed to transforming the landscape of personal health through its newly established Medical Intelligence Lab. This initiative is poised to harness the power of AI to assess and understand unique biological data on an unprecedented scale.

Sultan’s role will be pivotal as he leads product and technology teams to implement innovations that fundamentally change health engagement. His leadership is expected to enhance the company’s existing AI capabilities and streamline the introduction of pioneering applications such as Private AI Chat and Protocols, reflecting a significant shift in how health information is accessed and utilized.

Before joining Function, Sultan's remarkable tenure at Spotify was marked by groundbreaking advancements in personalization technology, where he oversaw a large team of over 500 professionals. His leadership facilitated the launch of notable features, including the AI DJ—one of the most successful consumer AI products globally. He played an integral role in enhancing Spotify's personalization engine, which powers various features such as Daily Mix and Discover Weekly, serving hundreds of millions of listeners worldwide.

“Function redefines what it means to take control of your health,” stated Jonathan Swerdlin, CEO and co-founder of Function. “Ziad’s proven skill in scaling AI and personalization will be crucial in making Medical Intelligence accessible to everyone.”

Sultan echoed this sentiment by noting the transformative potential of AI in addressing major societal challenges, particularly in health. He expressed his excitement about creating a product that empowers individuals to actively engage with their health through tailored insights and predictive data.

Function aims to provide comprehensive health solutions that surpass the limitations of the traditional annual physical. Rather than just measuring a limited number of biomarkers, Function offers over 160 lab tests every year, covering an extensive range of health metrics. This includes detailed assessments of heart health, hormonal levels, and cancer signals, making it easier and more affordable for individuals to take proactive steps towards their health. The company’s recent acquisition of Ezra facilitates MRI services powered by FDA-cleared AI, further ensuring that essential health screenings are within reach for many.

Function is on a transformative path that not only enhances individual health management but is set to redefine the standards of healthcare through technological advancement. As Sultan steps into his role at the beginning of 2026, his initiatives will shape the future of health tech, ensuring that every person has personalized access to their health data and insights. This evolution signals a promising future for health management, combining the best of AI and individual empowerment to create proactive health solutions for a healthier society.
