Formal appointment marks the nonprofit’s first leadership transition in 12 years and signals continued momentum in interoperability and data-driven diabetes innovation.

Tidepool, the nonprofit leader advancing interoperability in diabetes technology, today announced the formal appointment of Brandon Arbiter as Chief Executive Officer. Arbiter, a Tidepool co-founder who has served as acting CEO since April 2025, previously held the role of Vice President of Business Development and Strategic Partnerships. He succeeds Howard Look, who stepped down earlier this year to focus on his health.

The appointment reflects Tidepool’s continued growth and its expanding role as a trusted platform partner for innovation across the diabetes ecosystem. The announcement also reaffirms Tidepool’s founding belief that open data and community collaboration can fundamentally improve the lives of people living with diabetes.

“For more than a decade, Brandon has been an incredible partner—shaping Tidepool’s vision, deepening relationships with industry leaders, and leading some of our most impactful initiatives,” said Howard Look, Tidepool’s founding CEO. “His commitment to making innovative diabetes technology accessible to all has always been at the heart of his work. I am confident Tidepool will continue to grow with clarity and purpose under his leadership.”

Since his diagnosis with type 1 diabetes in 2011, Arbiter has combined personal insight with product leadership to shape Tidepool’s strategy and expand its reach across the diabetes community. He has been a driving force behind the Tidepool Data Platform and Tidepool Loop—a groundbreaking, community-designed automated insulin-delivery solution that received FDA clearance. That achievement led to the first commercial deployment of a Tidepool Loop–derived product through Sequel’s twiist AID System powered by Tidepool, paving the way for future partner-driven products.

“As CEO, my focus is on ensuring the solutions we build are accessible, impactful, and grounded in the real needs of the diabetes community,” said Brandon Arbiter. “With Tidepool+, Tidepool Loop, and our expanding data platform, we have a powerful opportunity to turn real-world data into better daily lives—to make proactive, data-driven diabetes care the norm rather than the exception, and to ensure that innovation truly serves everyone who needs it.”

Arbiter’s leadership approach has earned confidence across the organization and its Board. “Brandon brings a rare combination of vision, authenticity, and execution,” said Bryan Roberts, Tidepool board member and partner at Venrock. “Under his leadership, Tidepool is positioned to expand the reach of both Tidepool Loop and Tidepool+, advancing our commitment to make diabetes data more useful for people, partners, and clinicians alike. The Board’s decision reflects our deep confidence in Brandon’s leadership and the strength of Tidepool’s strategic direction.”

As CEO, Arbiter will lead Tidepool into its next phase of growth—expanding its interoperability infrastructure, deepening partnerships with device makers and health systems, and advancing Tidepool’s mission of making diabetes data more accessible, actionable, and meaningful across the entire continuum of care. His appointment underscores Tidepool’s enduring commitment to open collaboration and to standing with the diabetes community in pursuit of better, more connected care.
