I Built Software for Families Who Share a Holiday Home (So WhatsApp Stops Running the Place)

Sharing a holiday home with family or friends is great until the admin starts. Who’s in next weekend? Did someone already claim Easter? Who was meant to book the cleaner? Where’s the WiFi password / insurance cert / “how to winterize the outdoor taps” note?

Once you’re coordinating multiple households, peak seasons, and maintenance, the “calendar + WhatsApp” stack starts creating the arguments it’s supposed to prevent. I wrote a longer comparison here if you want the practical breakdown: Shared Holiday Homes vs Google Calendar What I built (and what I didn’t) The product is intentionally narrow.

In scope: One shared booking calendar Booking rules / seasonal rotations Shared task list Document library House guides (the handbook people can actually find) Out of scope on purpose: Selling property shares Matching investors Full bookkeeping / STR channel management That boundary mattered. Every time I was tempted to add “just one more admin feature,” I a
