Group B Labs founders

We get it, parenting is hard!

bubbe was inspired by the very real frustrations that founders and husband-and-wife team Illi and Olivia Eisner experienced when their children were infants. Illi—a computer engineer—and Olivia—an advanced registered nurse practitioner, certified nurse midwife, and board certified lactation consultant—started Group B Labs out of their own baby feeding challenges and those felt by hundreds of Olivia's patients.


With Olivia frequently pulling 24-hour shifts at the hospital delivering babies, Illi had the onerous task of bottle feeding. Turns out, warming up bottles at 3 a.m. or on the go is a totally miserable experience with spilled milk, long warming times, and imprecise temperature control, all made worse when juggling a screaming baby. 


Illi and Olivia imagined that there had to be a better way.

Experience +

By combining their unique expertise, professional insight, and shared passion for marrying healthcare, wellness, and technology in ways that elevate the caregiver experience, Illi and Olivia are the ideal team to deliver this much-needed innovation.


At the basis of their collaboration is a framework that focuses on patient wellness, intentional design, uncompromising integrity, and attention to detail. Illi’s strong background in consumer products and engineering and Olivia’s clinical expertise in maternal and infant health create a dynamic synergy for making impactful, problem-solving technologies.
