Feeld was founded in 2014 by Dimo Trifonov in London, United Kingdom. Trifonov, a Bulgarian-born software developer, created the app after wanting a platform for couples and individuals interested in exploring non-traditional relationship structures.
The app launched initially as 3nder (a play on Tinder), focusing on connecting people interested in threesomes and open relationships. The name and concept attracted significant media attention.
In 2016, Tinder's parent company Match Group sent a cease-and-desist letter to 3nder, alleging trademark infringement due to the similar name. The company rebranded to Feeld in 2016, a name chosen to reflect the broader concept of exploring the "field" of human connection and desire.
The rebranding to Feeld coincided with a broader expansion of the platform's scope. Rather than focusing narrowly on threesomes, Feeld positioned itself as a platform for all forms of ethical non-monogamy and alternative relationships, including polyamory, open relationships, swinging, and other consensual non-monogamous arrangements.
Feeld has grown steadily through the late 2010s and 2020s, building a global user base. The platform is particularly popular in major urban centers and among younger, progressive demographics.
Ana Kirova became CEO, bringing a focus on community, safety, and inclusivity to the platform. Under her leadership, Feeld has expanded its gender identity and sexual orientation options, allowing users to identify across a wide spectrum of identities.
Feeld has been featured in numerous media outlets as a leading platform for ethical non-monogamy and has benefited from growing mainstream awareness and acceptance of polyamory and open relationships.
