New Operating Systems for the Physical World: founder validation breakdown
Original RFS by Charlie Warren. Source: Y Combinator Requests for Startups.
The RFS in plain English
YC wants software for deskless work that moves beyond old dispatch, forms, and checklists into AI-native operating systems for real-world teams.
Why now
Most of the global workforce still works away from desks, while legacy field software has barely changed and mobile AI can now assist in context.
IdeaCheck angle
A strong startup should pick one vertical where workflow data, field context, and measurable operational outcomes compound.
Founder trap to avoid
Horizontal field-work software sounds large but often loses to vertical incumbents, offline edge cases, and slow change management.
A concrete idea to test
An AI operations system for HVAC service teams that turns photos, job history, inventory, and technician notes into next-step guidance.
