Our Advisers 

Helping Parabukas grow through their wealth of knowledge and experience


Bobby Julian

Bobby began his energy work in 1992 during the Philippine power crisis with Buenaventura Filamor Echaus (BFE), a financial advisory boutique specializing in energy projects. His remit later expanded to other infrastructure projects, exploiting opportunities enabled by the Philippine’s Build-Operate-Transfer (BOT) law and Public-Private-Partnership (PPP) program. He developed a personal interest and practical competence in environmental infrastructure (clean energy, water, and waste management), leading to his appointment as the country’s first UNDP PPP Specialist for the Urban Environment.

In 1995, Bobby served as CFO to a pioneering USAID project that sought to promote renewable energy through policy advocacy and financial investments in start-up clean energy enterprises, an effort that became the first Philippine social investment fund in clean energy. Bobby also funded the country’s first biogas power and solar companies, as well as worked with carbon investors operating under the Clean Development Mechanism (CDM), developing a competence in carbon finance and climate finance.

In 2005, Bobby joined Solar Electric Company as COO and pursued a personal project in the modern generation of electric jeepneys, the first units of which were introduced in the Makati CBD in 2007 to worldwide recognition. Bobby continues to consult privately on energy.

After graduating with a degree in philosophy from the Ateneo de Manila University, Bobby joined government as a Staff Assistant in the Technology Resource Center.
