Need help managing diabetes? These students made an app for that News

May 13, 2022 – Amber Nigam, SM ’23 and Jie Sun, SM ’22, would like to help people living with diabetes feel like they are living without it.

The two Harvard TH Chan School of Public Health students — both pursuing a master’s in health data science — co-founded a tech startup called to create an easy-to-use app that diabetes patients can use. Track their blood glucose levels, activities, diet, and other factors. This app uses a digital avatar to nudge people to adopt healthy habits to manage their disease.

“Instead of seeing boring lines and charts, the avatar is a human-like figure that keeps you motivated and engaged in your journey,” said Nigam. “You receive behavioral nudges from the avatar, such as’ I notice this thing you are eating is causing a spike in your blood sugar. Consider avoiding it or taking a smaller piece, or maybe getting some exercise. ‘ If your objective is, for example, to not take diabetes drugs any more, the avatar will tell you how far you are from your goal. “

The app provides personalized recommendations for diabetes patients.

Using’s patented artificial intelligence technology, the app provides precise and personalized recommendations. It translates to clinical consequences — like reducing the amount of blood sugar attached to hemoglobin — to more meaningful and relatable goals, like reducing medication or body fat. Patients can record most of their food and exercise data with a click of a button (or sync information via a device such as a smartwatch), and can monitor key glucose data from their data. They can also connect with health coaches if the digital avatar can’t answer a particular query.

Nigam and Sun won a Spark grant from the Harvard Innovation Labs last November, an MIT Sandbox grant in February, and they were both winning teams in the MIT $ 100K Entrepreneurship Competition’s Accelerate Contest in March.

Nigam became interested in providing an easier way to manage diabetes after seeing his father, who died from COVID in 2020, struggle with the disease. “My dad had unmanaged diabetes for 25 years,” he said. “He wanted to have sweets but he didn’t know them in front of me, so he would hide them. My mother and I would ask if he was checking his glucose, or we’d urge him to go for morning walks or do yoga or be active in some other way, but he didn’t listen much. We used to ask him to visit doctors but he owned a pharmaceutical company in India and had spoken to doctors so much that he was not interested. It was a very difficult situation. “

Through, Nigam and Sun hope to help diabetic patients like Nigam’s father has more autonomy in managing their disease. “Instead of being told by other people that you should eat this or not, that using our app can make people make small adjustments, step by step, and feel that they are the ones in control,” said Sun. She added that the app can help reduce global inequities by helping people with minimal access to health care achieve a healthier lifestyle.

Sun, originally from Singapore and China, and Nigam, originally from India, bring a combined 17 years of experience in tech entrepreneurship and health care to their startup. The two connected in April 2020 through a Slack group for students at Harvard Chan School’s health data science program. Nigam asked if his classmates were interested in starting a venture together — and Sun said yes.

The two have since put in long hours on their startup, often working in common spaces like Peet’s Coffee in Harvard Square (“We’ve been [there] So often that every staff there remembers our orders and names, “Sun blogged on March 17), and a lounge on the third floor of Child Hall, a Harvard dorm. Members of the Harvard community have been extremely supportive; Team members now include fellow students from Harvard Chan School and the Graduate School of Design. In a March 31 blog, Sun noted, “Everyone in the dorm has been welcoming us from offering us … hot meals, brainstorming on our patent application, or just casually chatting with us.”

Sun and Nigam also credit support from Heather Mattie, co-director of Harvard Chan’s master’s program in health data science. Mattie is one of the people serving on’s advisory board.

“It’s been an absolute pleasure working with Amber and Jie,” Mattie said. “They are two of the most driven students who embody the collaborative spirit of our community and our commitment to making health care more accessible to all. They are leveraging the power of data, data science, and a diverse set of skills to improve the chronic disease management journey for patients and their support systems. “

Nigam and Sun are partnering with hospitals and pharmaceutical companies to refine their offerings, and they are working to generate interest in the basys. Eventually, the plan is to make the app available to the general public, and to expand it to address not just diabetes but other chronic conditions.

“Working on our venture had such a strong impact on our lives,” Sun wrote in the March 31 blog. “We would urge every student to take the plunge.”
