Castle

Castle is a New York-based fintech building payments infrastructure for the roughly $3 trillion Americans spend on their homes each year. Its consumer app turns the chaotic paperwork of homeownership - utility bills, property and school taxes, insurance, renovations and maintenance - into a single digital filing cabinet with automated bill pay, transaction monitoring that surfaces tax credits, rebates and overcharges, and fraud protection. Founded by Madeline Hung after a gut-renovation of a historic Hudson Valley photo studio revealed how little data homeowners have on their biggest asset, Castle says its average customer saves over $10,000.
