In my previous roles at Chime, Apple, and Uber, we had sophisticated analytics and machine learning needs as we set out to deliver big goals for our customers. No vendor could meet our needs, so my teams built many things in-house. One example that I'm proud of is Michelangelo - Uber's ML Platform. These technologies contributed to billions of dollars of incremental revenue.Now, I am setting out to do this with Palladio AI. We are addressing large, unmet needs in advanced revenue and retention analytics for Product leaders. We deliver AI-powered guidance on opportunities and gaps to inform and prioritize product iteration investments.I want to help product leaders experience the same joy of making magic for customers and the revenue impact that follows, as I experienced at Chime, Apple, and Uber.
