Seattle Times:

Cozi brought them together for one of the unusual "Tupperware party"
events it’s been having at homes around the Seattle area for market
research and to introduce the suite of home-management software and
services it has been quietly developing over the past two years.

The moms are asked about the technology they use, the organizational challenges they face and the solutions they’d like to see.

Then they get a demonstration of the software, including a shared family calendar and shopping-list builder.

Listening in at a party hosted by Marjorie Landon, it was startling
to see how much data she and her friends store, sort and process to
keep their domestic operations running smoothly.
