Sean Duffy arrived at IDEO in 2011 as an MD/MBA student interested in primary care and chronic disease. With Adrian James, he began exploring how digital tools might support people between visits, where most decisions about food, activity, and health actually occur.
Their research brought them into the homes of people living with prediabetes and metabolic risk. The problem was not an absence of information. People were being asked to change repeated behaviors within the conditions of daily life, while much of healthcare was organized around intermittent encounters.
The founders also had a credible intervention to build from. A large NIH-sponsored Diabetes Prevention Program had shown that structured lifestyle change could reduce progression to type 2 diabetes in high-risk participants. The opportunity was not to invent behavior change from nothing. It was to ask whether the essential support could reach people without requiring them to attend an in-person group program.
Digitization was only the first move
Omada’s early program combined a remote curriculum with connected tools, peer interaction, and human coaching. That choice is important. The company did not treat software as a replacement for the relational work of behavior change. It used technology to make the intervention more available while preserving human service where it mattered.
But a program that participants liked still needed a buyer. Prevention creates an awkward economic problem: costs occur now, while benefits may appear later, possibly after an employee has moved to another health plan or employer. Omada had to show credible outcomes and make those outcomes legible to organizations purchasing benefits.
The company initially offered Prevent directly to consumers, but its durable route became business-to-business-to-consumer distribution through employers, health plans, pharmacy benefit managers, and other partners. Omada built an evidence program, obtained full recognition from the CDC for its digital diabetes prevention program, and experimented with contracts that connected payment to participation or outcomes.
This created a company that looked less like a downloadable application and more like a distributed care provider. Its economics depended on engagement over time. Its claims depended on clinical measurement. Its reach depended on institutional channels. Its service depended on people as well as software.
The model still has limits. People who enroll and remain engaged may differ from those who do not. Outcomes for one program do not automatically validate every later condition the company addresses. Employers and plans may also evaluate savings over time horizons that do not match the natural history of chronic disease.
Omada’s lesson is therefore not that digital prevention is proven in every context. It is that healthcare delivery emerges from alignment. The participant, coach, evidence base, purchaser, distribution partner, and economic model must work together. Moving the curriculum online widened access. Designing the system around it made the intervention purchasable as care.
