How Fi would pitch themselves
● Editorial01Target customer
Dog parents in urban + suburban US with active dogs — golden retrievers, huskies, mixed breeds prone to escape or anxiety.
02Problem they solve
Dog escapes account for 10M+ missing pets/year. AirTags don't have cellular fallback. Existing GPS collars (Whistle) are bulky + have poor battery.
03Key differentiator
Slimmest GPS collar on market + 3-month battery + LTE-M cellular. Lost-dog Find Mode + social network for dog-parent alerts.
04Go-to-market strategy
DTC e-commerce (Fi-only + Amazon). Influencer partnerships with dog accounts. Subscription monetization (cellular service $19/month).
