I brought in $789K last year selling landline phones
Kat Gatsy, 29, built a $789,000 business in 2025 selling Bluetooth-compatible landline phones. The idea came from her desire to reduce smartphone screen time while recapturing the nostalgia of shared family landlines. Her Stanford education and startup experience gave her the confidence to prototype and launch the product.
Summary
Kat Gatsy is a 29-year-old entrepreneur whose landline phone business generated approximately $789,000 in 2025. The concept originated from a personal realization that the colors on her smartphone screen appeared more vivid and appealing than real life, which she found alarming and symptomatic of excessive phone dependency.
The idea for a Bluetooth-compatible landline phone emerged in 2023, after Kat had spent roughly three years since the COVID pandemic trying to reduce her overall smartphone usage. She felt nostalgic for the era of shared family landlines, when phone time was naturally limited and communal. However, when she researched how to actually get a traditional landline, she discovered it required a separate phone number and cost at least $70–$80 per month — barriers she was unwilling to accept.
Drawing on her technical background, Kat reasoned that connecting a landline handset to a smartphone via Bluetooth shouldn't be overly complex, and she began tinkering and prototyping to make it work. Her academic foundation came from studying Science, Technology, and Society at Stanford University. Early career experience working closely with C-suite executives at startups demystified entrepreneurship for her, leading her to believe that if they could build and run companies, so could she.
