Brian Marshal

Founder & CEO of SIRCLO, building Southeast Asia’s digital commerce and nurturing Indonesia’s future leaders.

I started SIRCLO in 2013 to help brands sell online. Today we're Indonesia's leading e-commerce enabler, powering brands across their own stores and platforms like TikTok and Shopee.

Before SIRCLO, I won a bronze medal at IOI 2007, studied Computer Science at NTU Singapore, and worked as a consultant at PwC. I'm also an alumnus of the Stanford Executive Program at Stanford GSB. Outside of work, I mentor students through the Informatics and AI Olympiad communities (TOKI), and I support short films when I get the chance.
