Neo was born in Belgium and developed an interest in video games and content creation at a young age. He has cited early exposure to New Super Mario Bros. Wii as an inspiration for wanting to create YouTube videos.

He has expressed aspirations to become both a game developer and a YouTuber.

Neo began his content creation journey in 2022 under the channel name infepisodealessio, where he initially planned to upload general gaming content. Early attempts did not gain significant traction.

In 2023, after posting a video about a personal injury, he received more attention than on previous uploads, which motivated him to continue creating content. He later experimented with CapCut templates before deciding to move away from that style.

He rebranded his channel while retaining his subscribers and began creating Brawl Stars content, where he saw moderate success. During this period, he also created profile pictures related to the game that were used by members of his community.

After losing interest in Brawl Stars, Neo shifted his focus to Minecraft, aiming to create more authentic content. He launched the NeoThiefGuy channel, where he began focusing on Minecraft videos.

His growth has been supported by involvement in online communities, including CosmeticBoot's community and others. He also organized a community event known as the Spear SMP, which contributed to renewed channel growth.

NeoThiefGuy’s content focuses on Minecraft gameplay and community-driven projects. His work reflects experimentation and gradual improvement as he refines his style.

In addition to content creation, he has expressed a strong interest in game development and continues to balance YouTube with school.

HIs main goal is to one day join the LifeSteal SMP as it was his main inspiration to create content.
