HeyAlfie
Company Overview:
We’re on a mission to revolutionise homeownership by building an AI-powered PropTech platform that makes managing a home effortless.
Homeownership should be simple, but today it’s anything but. From handling maintenance and repairs to finding the right service providers and staying on top of admin, managing a home is fragmented, time-consuming and inefficient.
We believe there’s a better way.
Our platform combines automation, expert guidance and seamless access to trusted services. By leveraging AI and proprietary home data, we’re redefining how homes are managed. What was once a reactive process becomes proactive, intelligent and stress-free.
We’re VC-backed, launching in 2025, and building the foundation for a global, scalable, AI-native platform that will transform home management.
