KEY POINTS

•Sofia Hernandez has left TikTok after nearly six years handling their global marketing and consumer advertising strategies.
•Isobel Sita-Lumsden from the UK will replace Hernandez, focusing on off-platform marketing partnerships and social engagement.
•This exit follows other high-profile departures, including TikTok executives Blake Chandlee in March 2025 and Kim Farrell in January 2026.

Sofia Hernandez, TikTok’s global head honcho of marketing and commercial partnerships, has packed her bags after starring in the company’s ad circus for nearly six years. From chief customer officer at Suzy (no relation to a circus elephant) to Publicis Groupe agency fodder, she mastered the art of confusing consumers and advertisers alike. Her replacement? Isobel Sita-Lumsden, a UK exec whose main claim to fame is off-platform social sorcery. This exit comes hot on the heels of a US exec exodus, including Blake Chandlee stepping down in March 2025 and Kim Farrell smashing the creator’s chair in January 2026. Meanwhile, TikTok keeps shuffling its deck, splitting its US biz among Oracle, Silver Lake, and MGX—who knew marketing was this much like musical chairs?
