Mariano Divittorio

Mariano Grandoli was born on July 1, 1981, in Rosario, Argentina. He started playing poker in his early twenties and later moved to the United States. On February 25, 2019, he launched his poker vlog on YouTube, initially grinding $1/3 live cash games at casinos such as Bellagio, Aria, Commerce, and The Bike.

Grandoli's popularity surged through his appearances on Hustler Casino Live (HCL), the most-watched poker stream. He quickly replaced Garrett Adelstein as the headliner in the highest-stakes games. As of April 2026, he was up over $3.4 million lifetime on HCL, according to HighRollPoker.com, and posted staggering seven-figure profits in 2025.

One of his most famous hands occurred on HCL in April 2026. With a 4% chance to win, Grandoli hit a runner-runner flush to scoop a $392,400 pot against Phuoc "Turbo" Nguyen. The hand, where he held K♠5♠ against Turbo's A♥8♠ on an A♦8♣3♠ flop, ended with the 6♠ on the river. Commentator Charlie Wilmoth exclaimed, "How does he do it?"

Grandoli has also been involved in massive pots, including a $660,000 pot against Nik Airball and a $909,000 cooler that he lost on the river. Despite the swings, he has maintained a reputation for running extremely well on stream.

Grandoli is known for an insanely aggressive approach, often making large bluffs and putting opponents to tough decisions. His style has been compared to a mix of luck and skill, with his brilliant plays sometimes overshadowed by his fortunate outcomes.

In just four years, Grandoli ascended from low-stakes vlogger to high-stakes crusher, inspiring a new generation of poker players. His YouTube channel and HCL appearances have made him a household name in the poker community.
