Step 2 Difficulty managing home care aides
→
Step 3 Securing substitute care workers during sudden absences

Problem

Middle-aged adults (50-60) hiring home care aides for their parents in their 80s face 1-2 days per month when the aide suddenly falls ill or has personal conflicts. Finding a substitute requires calling the care agency and waiting, and same-day replacements are nearly impossible. Someone in the family ends up taking a half-day off work, or the elderly parent is left alone for the day. Care agencies also lack a systematically managed pool of available substitute workers.

Solution

Local care workers register their 'available swap days,' and when sudden absences occur, a substitute with matching certification level and similar experience is matched instantly. First, care workers register their weekly availability. Second, when an urgent swap request comes in, workers in the same area with similar experience receive notifications and auto-assignment upon acceptance. Third, the family is notified with the substitute worker's profile and estimated arrival time.

Revenue Model: Worker registration and basic matching free, $3.75 per successful emergency swap match (includes supplemental pay for the substitute worker), B2B workforce pool management Subscription for care agencies
