Business Agustin is involved in numerous restaurant businesses. In 1999, as part of an endorsement deal, he received a franchise outlet of
Mister Donut, marking his first business venture. He subsequently launched Ricecapades, a chain of rice-based food stalls, which became his first entrepreneurial foray into the restaurant industry. Agustin later established Oyster Boy Restaurant, a seafood-dining concept that expanded to multiple branches in Metro Manila. In December 2005, he co-founded Sumo Sam, a Japanese–American casual dining chain, with its first outlet at
Shangri-La Plaza Mall in
Mandaluyong. Agustin co-founded Oh Crop! in 2021, a social enterprise focused on promoting adlai— a locally grown Philippine grain, by partnering with farmers to improve their income and highlight underutilized local crops. In 2023, Agustin launched Cochi Bistro, a
fine‑dining concept in
Bonifacio Global City that centers on roasted suckling pig (
cochinillo) prepared in a Spanish style and paired with modern Filipino and international dishes. The concept traces its roots to his
cloud‑kitchen brand Secret Kitchen, which opened a mall stall for cochinillo and baked goods in 2022. He described the venture as a pandemic‑pivot inspired by his in‑garage baking experiments while developing his oven‑based cooking. In 2025, Agustin's Cochi was awarded a
Bib Gourmand by the
Michelin Guide Philippines. Aside from his food ventures, Agustin owns Futuretainment Inc., a company specializing in the production of concerts and live events. The company has produced shows for both local and international artists and expanded into television content, including the singing competition
Kanta Pilipinas on TV5.
Philanthropy and advocacy In a 2000 interview, Agustin stated that he had established the small foundation Kaibigan ni Marvin Agustin Inc. (KAMAI), which operated for two years. Its early activities included visits to Golden Acres to interact with the elderly and a birthday‑party outreach for street children. In 2012, he organized a birthday-party outreach for children from Operation Smile Philippines at
Enchanted Kingdom, providing food and presents during the event. The following year, Agustin expressed his intention to organize a volunteer group for relief operations following
Typhoon Yolanda. He also supported a children's character‑building campaign by
Bear Brand, emphasizing the importance of teaching children resilience and leadership skills in 2014. In 2016, Agustin established the Entreplab School, a senior high school focused on entrepreneurship education. During the
COVID-19 pandemic in 2020, Agustin urged restaurant owners to donate food to hospitals and
frontline workers, suggesting that perishable stock be cooked and given to those in need. He offered his restaurant kitchens to support a fundraiser for street vendors affected by the pandemic, organized by
Bela Padilla. In 2021, he marked August 10 with a food distribution event for community members, playfully referencing the meme connecting his surname with the date. In 2022, Agustin was appointed as an agri-aqua ambassador by the
Department of Science and Technology –
Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development (DOST‑PCAARRD), promoting agricultural and aquaculture awareness and education. In this role, he creates content, shares information about native agricultural commodities, and highlights the use of local produce to benefit farmers, business owners, and consumers. In 2025, Agustin served as ambassador of
WorldSkills Philippines. He also took part in
ABS-CBN Foundation's Kapamilya Golf Fundraiser,
Swing for a Cause.
Endorsements Agustin has endorsed numerous products throughout his career, ranging from food and beverage brands to personal care and household items. In the late 1990s, he served as brand ambassador for Mister Donut, a partnership that earned him his own franchise. In 2008, he signed endorsement contracts with clothing brand Urban Edge and Lana de Herba Oil and Ointment. He has also promoted products such as
Del Monte and
Tupperware. In 2012, he was named a celebrity ambassador for Knorr cubes and later that year became an endorser for CarbTrim. ==Personal life==
