BorrowMyDoggy is an online platform that connects dog owners with people interested in temporarily caring for dogs. It aims to help busy dog owners find low-cost care for their dogs when traveling or working, while also helping people who miss having a dog but cannot permanently own one. The platform launched as a weekend project and gained over 80 signups in its first test, demonstrating the viability of the idea. It has since developed processes for matching users, verifying identities, and automating systems while expanding features, coverage, team, and fundraising to build the business further.
