Hi, I'm Roy Lo.
I'm a product leader, former startup founder, and hands-on software engineer.
In 2016, I bootstrapped a SaaS business focused on messaging marketing automation, which grew to serve hundreds of enterprise clients and was acquired by Appier (4180.T) in 2021.
My journey spans web development at Yahoo!, iOS engineering at two early-stage startups, founding and scaling BotBonnie, and leading cross-functional product teams at Appier.
I recently earned a master's in management from Stanford Graduate School of Business.
At every stage, I've deepened my curiosity, sharpened my problem-solving, and built the instincts to thrive in fast-moving, cross-disciplinary environments.
