Marketplace Connecting Parents And Vetted Sitters

Nanno lets parents book high-quality, fully vetted sitters on-demand. Nothing is more important to our parent users than their children’s safety. That’s why we’ve built a proprietary 5-step vetting process, which includes a thorough criminal background check, a safety skills test, and a psychometric behavioral test. Nanno is the safest way to book a sitter, online or offline.
