Arbiter served as acting CEO since April 2025 after founder and CEO Howard Look stepped down to focus on his health. He previously held the post of VP of business development and strategic partnerships at the automated insulin delivery technology developer.
According to a news release, Arbiter served as a driving force behind Tidepool’s technologies. Diagnosed with type 1 diabetes in 2011, Arbiter has spent the last 12 years at the company.
“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.”
Tidepool said the appointment reflects its continued growth and expanding role as a partner in the diabetes ecosystem. The non-profit diabetes data management group developed the FDA-cleared Tidepool Loop, a “do-it-yourself” (DIY) automated insulin delivery (AID) system. The hybrid, closed-loop AID app has compatibility with multiple insulin pumps and continuous glucose monitors. Recent collaborations include integrations with Abbott and Sequel Med Tech, among others.
“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.”
