Our mission is to accelerate progress toward a smaller, fairer, safer criminal justice system—and to do so at-scale. Recidiviz is a tech startup through and through: we take the speed and problem solving of the tech world and apply it to big public policy challenges where there is huge opportunity for impact. Using modern data infrastructure and thoughtful product design, we’ve been able to safely and permanently reduce incarceration and improve outcomes. We work side-by-side with justice-impacted communities, ecosystem partners, and leaders of the criminal justice system to build a better path forward. In addition to the revenue we earn from states, some of the most respected philanthropists and foundations—including Arnold Ventures, the Chan Zuckerberg Initiative, and the Mozilla Foundation—support our work.

With Fella Health, patients meet a board-certified obesity doctor to prescribe FDA-approved medications, while they undertake personalized health coaching through our app. Obesity is the largest chronic disease in the US (>$100bn spent each year) and the traditional solution ("move more, eat less") only works long-term for ~10% of people. But obesity treatment is radically changing due to a new wave of medication options which are 2-3x more effective than previous options. In addition, only 10% of those using weight management services are men: all programs market to women, not tackling the stigma men feel around this. Fella's founders are Luke (linkedin.com/in/luke-harries) & Richie (linkedin.com/in/richard-cartwright). We studied together at Cambridge University. Luke studied medicine and developed a patented AI approach to detecting cancer at a YC bio company, before moving to Microsoft Research. He did a masters in Computer Science after Cambridge. Richie personally struggled with stress eating for 6 years. After Cambridge, he built and sold an AI company working with the UK government. He built a 10k-follower community around men's stress eating.
