Founder of MacroAsia Corporation, Founding Investor of Rappler, Benjamin "Benjie" Mendoza Bitanga (born December 31, 1952) is a Filipino investment banker.

Bitanga attended Ateneo de Manila University, where he graduated in 1973 with a Bachelor of Science Degree in Management.

In 1995, he implemented a widely successful initial public offering (IPO) of the company with the Philippine Stock Exchange, which attracted local and foreign investors like SSS (Social Security System) and GIC (Government of Singapore Investment Corporation).

He was responsible for converting MRC's 350 hectare property in Cebu to a planned world class township which led to its classification as an Export Processing Zone.

In 2011, Bitanga became a founding investor of Rappler, a pioneering online news platform, through his family-owned Menlo Capital Corporation.

Rappler, led by Maria Ressa, has been instrumental in shaping the landscape of digital news in the Philippines.

Rappler's mission, combined with Bitanga’s vision for supporting transformative media ventures, has played a pivotal role in fostering press freedom and accountability in the Philippines.

Under Menlo's ownership and with a new management team, PT&T achieved several key milestones, including holding its first stockholders' meeting in 14 years, securing approval to increase its capital stock, and resolving past violations with the Securities and Exchange Commission (SEC) and the Philippine Stock Exchange (PSE).

Bitanga is currently the controlling owner of a diverse range of businesses across various sectors, including investments, real estate, renewable energy, and telecommunications.
