Johan Brissmyr is the CEO and co-founder of Castle, a security company that helps online businesses detect fraud, bots, and account takeover in real time. A computer scientist from Lund University, he started building web products in Malmo, Sweden before moving to Silicon Valley through Y Combinator and relocating the company to New York. Castle grew out of a password-storage side project that revealed a bigger opportunity in behavioral risk scoring, and today combines device fingerprinting, behavioral signals, and analytics into APIs used by companies of many sizes.
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.

Madeline Hung is the co-founder and CEO of Castle, a Hudson, New York fintech building payments infrastructure for the home - software that helps homeowners automate, consolidate, and reduce the cost of their biggest asset. She arrived at the idea the hard way, converting a derelict Hudson Valley photography studio into a livable house during the pandemic and discovering that tracking home spend felt like writing paper checks into a black hole. Before Castle she co-founded The Good Country with nation-branding strategist Simon Anholt and worked across human-rights research and citizen-engagement ventures, a path that runs from Oxfam and Health Leads to a seed-funded home finance app.
