AtHeart

Titan Content was established on November 28, 2023 by former SM Entertainment CEO Nikki Semin Han, who serves as chairman. The company's leadership includes former SM Entertainment artist planning head Katie Kang as CEO, DAZED KOREA editor-in-chief Guiom Lee as chief visual officer, 1MILLION Dance Studio co-founder Lia Kim as chief performance officer, and former SM Entertainment US senior vice president Dom Rodriguez as chief business officer. Titan Content markets itself as the first American-based entertainment company prioritizing K-pop, with studios in Los Angeles and Seoul.

Global auditions took place across North America, Australia, and Asia in 2024. On July 16, 2024, Titan Content announced Michi and Sorin as the first members. Sorin later did not debut with the group. The group name AtHeart combines 'Heart' to represent connection and love between the members and fans. Members were introduced gradually from 2024 into 2025. The pre-debut single 'Good Girl (AtHeart)' was released on May 29, 2025. AtHeart officially debuted on August 13, 2025 with the EP Plot Twist at Seoul's Bluesquare SOL Travel Hall. [edit]

Titan Content attracted seed funding led by RW3 Ventures and Raptor Group, with Dreamus Company as co-lead investor. Other investors included Animoca Ventures, Sfermion, Bell Partners AB, Heros Entertainment, Infinity Ventures Crypto, Scrum Ventures, Planetarium, and Avalanche. The company aims to combine traditional K-pop business models with Web3, metaverse, and AI innovation.

Michi was the first member cast, discovered in Hawaii. CEO Katie Kang said, 'When I saw her, I had that feeling that she was the one, and I can now finally start putting together a group around her.' Training focused on singing, dancing, and mental preparation for the non-performing aspects of a K-pop career. The group's multinational lineup includes members from Korea, Japan, the Philippines, and the United States. [edit]

AtHeart's early sound centers on polished pop with contemporary R&B influences. Their pre-debut single 'Good Girl (AtHeart)' features a bubblegum-pop sound with a schoolgirl concept. The debut EP Plot Twist is a five-track pop album described as 'deliciously catchy and melodic.' Production involved Jonah Shy, who has worked with Chappell Roan and Camila Cabello. Lyrical themes emphasize self-discovery and resilience. Post-debut, the group released 'Plot Twist (English ver.)' and 'Plot Twist (Remixes),' followed by singles 'Shut Up' and 'Butterfly Doors' in 2026. [edit]

AtHeart represents Titan Content's ambitious entry into the K-pop market, backed by former SM Entertainment executives. The group's multinational lineup reflects the globalized nature of modern K-pop. Their debut attracted attention from major outlets including Variety, Teen Vogue, Billboard, and The Hollywood Reporter before their official debut. Billboard named AtHeart one of the 'Next-Generation' K-Pop Groups and K-Pop Rookie of the Month for August 2025. The group's music video teaser featured Girls' Generation's Sooyoung, highlighting industry connections. [edit]

The official fandom name is Heartbeat. The lightstick design and fan color have not been officially announced. The group's fan community is still in its early stages, with members active on Instagram and TikTok. Arin and Bome have individual social media accounts (@arinatheart and @bomeatheart on Instagram and TikTok). [edit]

AtHeart is Titan Content's first girl group. Former SM Entertainment CEO Nikki Semin Han serves as the company's chairman. Choreographer Lia Kim, co-founder of 1MILLION Dance Studio, is chief performance officer. DAZED KOREA editor-in-chief Guiom Lee is chief visual officer. Nahyun was a former SM Entertainment trainee, born on September 3, 2009 in Cheongju, South Korea; she draws inspiration from IVE's Jang Wonyoung and her motto is 'Don't be negative and always smile.' Aurora went on a health-related hiatus on July 2, 2025, limiting her participation in the debut EP. Girls' Generation's Sooyoung appeared in the group's music video teaser. The group appeared on Mnet's 'M Countdown,' MBC's 'Show! Music Core,' and SBS's 'Inkigayo' in 2025. [edit]
