Mariano Grandoli

Mariano hails from the Argentine city of Rosario. At 16, he moved to the US to attend California State University, majoring in business and economics. Three years later poker took over his life, and he launched a YouTube channel that would eventually make him a known name in the community.

Mariano's professional career began at the low limits in various Las Vegas and California casinos, while he worked a side job delivering pizza for Pizza Hut — he got fired before long for skipping too many shifts, since balancing both proved harder than it looked. Around the same time, he started filming his first poker vlogs. Strong results and a growing bankroll pushed Grandoli up the stakes quickly, and by 2021 he had already appeared on his first Hustler Casino Live show.

His aggressive style made him a fast favorite on poker streams, and opponents even gave him the respectful nickname "King Argentina." By 2022, Grandoli had become a regular at various high-stakes shows, and his Hustler Casino Live profit had crossed the $500,000 mark.

Success at the tables didn't slow down his YouTube output — Mariano kept churning out quality content, often filmed right from the casino floor. In 2023, he was nominated for a Global Poker Award in the "Best Vlogger of the Year" category. That same year, he won one of the largest pots in HCL history at the time — $788,000.
In 2024, Mariano scaled back his table time somewhat; music took over part of his attention, and he founded a band called Dear Delta, where he plays drums. That didn't stop him from banking roughly $500,000 in poker winnings and growing his YouTube audience even further. Early in 2025, he set a personal record, winning a $909,400 pot on Hustler Casino Live, and by 2026 his channel had crossed the 200,000-subscriber mark.
