FAST COMPANY - Feeld, a dating app catering to non-monogamous relationships, faces growing pains amidst rising interest in ethical non-monogamy (ENM). Users experienced login issues and lost matches due to a major app update, impacting even those with paid memberships. Despite frustrations, Feeld's community remains loyal, valuing the app's role in connecting individuals seeking non-traditional relationships. Feeld was created by Dimo Trifonov and Ana Kirova in 2014 as 3nder, to address their own desire for a platform supporting couple dating. However, legal hurdles soon emerged, including a copyright infringement lawsuit from Tinder, which Trifonov criticized as corporate bullying.
