Ann Holder describes her path to entrepreneurship as “convoluted.” She spent more than three decades in engineering, finance, sales, and operations roles in the U.S. Army and at companies like General Mills. While serving as executive director of integrated health solutions at Medtronic in 2015, Mayo Clinic recruited Holder to its Entrepreneur in Residence program, where she worked with Mayo doctors to launch health care startup Marani, a tech-enabled digital health platform for prenatal and postpartum care. In addition to standard biometrics, the company is developing a wireless, reusable product for maternal and fetal monitoring at home. So far, Minneapolis-based Marani has raised $10 million in funding. In 2022, Holder says Marani will focus on getting FDA clearance for its medical device.
