Preston Schlagheck

Born in Hartford, CT, now based in Columbia, SC, where I study Finance & Business Analytics at the University of South Carolina.

I’m Head of Product at Mano Wellness, where we built Manny, a private health coach that adapts to you. It reads your wearables, sleep, and nutrition to track your habits and hold you accountable. Since launching in September, Manny has grown to hundreds of users with no paid marketing and is live with 4+ corporate clients. Available on iPhone and web.

I also work at Direct Journeyline Holdings, where I automate month-end reconciliation, reporting, and forecasting across a multi-company truck parking and logistics portfolio. My tools save the team 10+ hours a week.

Before that I co-founded Diffuse and CogNodes, where we built different AI products for clients. Recently we finished Lookr, a fit-based feed that gives you live outfit feedback and matches you with people who dress like you and wear your sizes.

I’m recruiting for Summer 2027 internships in finance, operations, and supply chain, especially roles where finance, data, and AI meet.
