About
Marcus Dantus is a Mexican entrepreneur and angel investor best known for spending seven seasons listening to founders’ pitches on Shark Tank México. A serial company‑builder since the early 1990s, he founded the venture hub Startup México in 2013 and later became managing partner of the seed fund Dux Capital. Thanks to those roles—and to his friendly, plain‑spoken style on television—he has turned into one of Latin America’s most visible champions of small businesses and tech innovation.
Before Fame
Dantus was born in Mexico City on November 7, 1966. A love of storytelling first pushed him toward film school, but curiosity about computers soon took over, so he completed a degree in Media Communications at the University of Pennsylvania. Back home in 1993 he launched Mexico.com, selling personalized e‑mail addresses and registering Spanish‑language web domains; a Silicon Valley fund even wired in $8 million just before the dot‑com bubble burst. Those wins and losses shaped his practical, “fail fast and try again” attitude, which later helped him steer Telefónica’s accelerator Wayra México and inspire hundreds of young founders/
Trivia
- First domain sold: He earned US $20,000 in the 1990s for handing over Andale.com, proving that Spanish keywords had real market value.
- Teaching streak: After exiting several start‑ups, he “retired” briefly to lecture on entrepreneurship at IPADE Business School—only to jump back into start‑up life months later.
- Favorite failure anecdote: During a 2025 Fuckup Nights platform he quipped that lawyer letters, and not rivals, ended his first business when brands objected to their titles being registered.
- Resilience mantra: In a 2024 podcast he credited his grandfather for showing him how to bounce back from setbacks—a theme he repeats to nervous Shark Tank contestants.
Family Life
Even though Dantus has most intimate information off-camera, he frequently greets his “esposa y madre de mis hijos” with affectionate messages on social media and expresses gratitude towards his mother and grandmothers for early encouragement. His Mother’s Day 2025 online greetings affirm that he is married and father of at least two. Family moments—giving thumbs-up to school functions or birthdays—keep cropping up between business advice, indicating home life is still a priority despite a busy schedule.

On Shark Tank México (2018 – 2024) Dantus shared the panel with high‑profile investors such as Arturo Elías Ayub, Patricia Armendáriz, the late Carlos Bremer, Alejandra Ríos, and Simón Cohen. He also collaborates off‑screen with ecosystem figures like Mauricio Hoyos (Shark Tank Colombia) on cross‑border deals, and partners with organizations such as the Global Entrepreneurship Network to mentor founders worldwide. Even though he stepped back before the show’s 2025 tenth‑season reboot, his advice and quick humor remain part of the program’s highlights that circulate online.
