Perfect metabolic recall to answer all your questions

We integrate previously unused data, and apply machine learning to give you personalized information about how your body breaks down carbs.

Turn mealtime guesstimating into data driven decision making

We link CGM, insulin pump, apple health, and location data to create a new model for understanding, analyzing, and searching, metabolic history.

Constantly improving and optimizing with your provider

We offer new tools for your provider to improve treatment for your daily routine (and your nights out 😉)

Our team

We're a group of builders looking to increase time in range, and reduce time on mind.

Sam Royston
Founder, CEO

Sam is a Type-1 diabetic who understands the disease and it's technological evolution intimately. He studied Machine Learning at the Courant Institute @ NYU, and Mathematics at Lewis and Clark College. Previously, he designed the core anomaly-detection technology behind VoteShield (backed by Eric Schmidt & Reid Hoffman), where he scaled the team to 15. Prior to VoteShield, Sam was an ML engineer at various startups and studied blood glucose prediction algorithms and data visualization at NYU.

Brad Jacobson
Operations & Design

Brad watched his grandmother care for his grandfather for over 3 decades, and the painstaking work she had to put in every single day. He studied Psychology at Dartmouth College (BA) and Human Centered Design and Engineering at University of Washington (MS). He led product management, design, and research work streams for fortune 500 companies like Nike, Verizon, and Samsung while at R/GA.

Dr. Mike Natter
Advisor

Mike is a board certified Internist and Endocrinologist at a major academic hospital in NYC. He is also a patient, he was diagnosed with type 1 diabetes at age 9. Natter was awarded the Endocrinology Fellow of the year award both years of his fellowship as well as the fellow’s teaching award in 2022. Additionally, he was awarded the Courage to Heal award by Jefferson Medical College in 2023. He has lectured across the globe and brings experience from both sides of the exam table, as a patient and a physician.

Sam Royston
Founder, CEO

I’m a technologist and machine learning engineer by training, having studied ML at the Courant Institute @ NYU and Mathematics at Lewis and Clark College. I was fortunate enough to build the core machine learning anomaly-detection technology, and lead the engineering team at VoteShield (backed by Eric Schmidt & Reid Hoffman) where I scaled the team from 0 to 15 employees before starting Replica. Before VoteShield I worked as a machine learning engineer at various companies, and before that I studied blood glucose prediction algorithms and data visualization at NYU. I’ve had success starting multiple ventures throughout my career, even including a news website in West Africa back in 2013, but most importantly I am a Type-1 diabetic and understand the disease and its technological evolution intimately.

Brad Jacobson
Operations & Design

I am passionate about improving T1D care because I watched my grandmother care for my grandfather for over 3 decades, and the painstaking work she had to put in every single day. I studied Psychology at Dartmouth College (BA) and Human Centered Design and Engineering at University of Washington (MS). I’ve led product management, design, and research work streams for fortune 500 companies like Nike, Verizon, and Samsung while at R/GA. Most recently, I built VoteShield with Sam from an idea to a world class machine learning product for Election officials around the United States.

Dr. Mike Natter
Advisor

A board certified Endocrinologist at a major academic hospital in NYC, and type 1 diabetic since age 9. Offers unique perspective from both sides of the exam table, being both a patient and a physician.
