Early life and education Jacoby was a student at Stanford University, where she studied symbolic systems. She spent one year of her studies in a circus in Brazil, where she taught acrobatics to gang members. This experience prompted her to carefully evaluate the criminal justice system. She became increasingly concerned about the high numbers of people imprisoned in the United States. In particular, she looked for low-cost solutions to mass incarceration. Of the 2.5 million incarcerated Americans, hundreds of thousands pose no risk to public safety. One in four prison admissions occur not because someone committed a crime but because they violated rules whilst on supervision. However, the data required to free them from prison is often distributed across several departments. Jacoby's work looks to make real-time data available for justice agencies and, ultimately, reduce recidivism. a nonprofit platform that allows states to collect, clean, standardize and share fragmented data. It collects data from prisons, probation and parole. Recidiviz makes use of an algorithm to recommend people for early release, so-called smart decarceration. North Dakota made use of Recidiviz to identify inmates who were eligible for release. In one month, prison populations in North Dakota were reduced by 25%. Jacoby partnered with the Charles Koch Institute to expand Recidiviz to 15 states. 2021 TIME100 NEXT 2022 Appointed TED fellow
