She views her success as tapping into a cultural and emotional desire for physical phone experiences.
Summary
Kat Gotsick is a 29-year-old entrepreneur who built a landline phone business that generated approximately $789,000 in 2025. She describes her approach to product development as holding 'an antenna into the zeitgeist,' sensing what people want creatively, spiritually, and emotionally — suggesting the success of her products is rooted in cultural timing as much as technical innovation.
Her core product is a Bluetooth landline phone that pairs wirelessly with a smartphone. Once connected, the physical handset rings alongside the smartphone for incoming calls, and picking it up initiates the call while setting it down ends it. Outbound calls can be dialed manually on the handset. Recognizing that many people no longer have phone numbers memorized, she built in a feature where dialing the star key activates Siri, allowing users to place calls to saved contacts by voice.
The phones are compatible with FaceTime, WhatsApp, and standard phone calls for both inbound and outbound use. Her product lineup includes rotary phones, which are among her top sellers, as well as a red wall-mounted phone. She also previews an upcoming model expected in spring 2026, which she notes closely resembles her original 2023 prototype — describing it as her personal favorite.
