2005–2011: Hired by SBT and presenting Sábado Animado Maisa was discovered in 2005, when she participated in Programa Raul Gil, on RecordTV and, later, on Rede Bandeirantes, dubbing hits by the group Rouge, Ivete Sangalo and Wanessa.

[5] Her first studio album, Tudo que Me Vem na Cabeça, released through Universal Music in 2009, brought songs that became her trademark, such as Tempo de Mudar, Pipoca Pula, Me Liga, and Tudo Que me Vem na Cabeça, with guest appearances specials such as Eliana, Jorge & Mateus, Ivete Sangalo and Roger Moreira (from the band Ultraje a Rigor).

She left Bom Dia & Cia on October 12, 2011, to play Valéria Ferreira, the girlfriend of Davi Rabinovich (Guilherme Seta), in the remake of the soap opera Carrossel, a plot adapted by Íris Abravanel.

The EP was produced by Otávio de Moraes and remained on the Brasil Hot 100 Airplay charts for a long time.

[25] In 2020, she was in Milan to watch the Dolce and Gabbana fashion show with other young internet influencers from different parts of the world, in addition to participating in an action by the brand for TikTok.

Alongside her businessman – and now partner, Guilherme Oliveira – Maisa created Mudah, an agency that aims to connect brands and artists for work and actions in the areas of influencer marketing and advertising.

In October 2013, at the age of eleven, she announced that she would no longer wear her characteristic curls in her hair, as she preferred to leave it straight.

[33] The presenter declares herself a feminist "Having the notion that, historically, women have been labeled and limited awakens [in me] the desire to be a woman, to use this to my advantage", she stated.

[34][35][36] The length of her career, popularity and great experience with communication and media, made Maisa, despite being young, a respected name to speak about her areas of activity.
