Prostir
February 2026
HouseholdOS for residents who want shared living to feel calm, clear, and coordinated.
The missing layer in shared living
Most shared homes run on a loose mix of group chats, spreadsheets, bank transfers, and memory. Prostir brings the parts a household shares into one focused place.
It is designed around the home rather than around a single tenant. Residents can understand what needs attention, make decisions, and move on with their day.

Shared finances, utilities, and home security in one view.
One home, one system
Prostir connects the routines that usually become fragmented:
- shared finances, balances, and upcoming dues
- bookings for bathrooms, laundry, and common spaces
- household routines and notification preferences
- guest access and temporary codes
- utilities, energy usage, and connected-home controls
The goal is not to turn a home into a dashboard. It is to make coordination quiet enough that the people living there can focus on living.
Product direction
The first version focuses on visibility and everyday coordination: clear state, few decisions per screen, and actions that make sense without onboarding.
