Jaime Hing III

2x fintech founder

I co-founded PayMongo, a YC-backed payments company in the Philippines, in 2019 and served as CTO. PayMongo built a modern payment platform enabling businesses to accept online payments through developer-friendly APIs and tools that could be integrated in under an hour. Prior to my departure in 2023, the company raised a $ 31 million in Series-B funding.

In 2023, I co-founded PayRex, a payments infrastructure company building a modern, end-to-end platform for businesses in the Philippines. PayRex enables businesses to accept payments and streamline financial operations through developer-friendly APIs and tools that can be integrated in under an hour.

Loves building startups with infrastructure play

I'm interested in startups that solve foundational problems, the kind that sit beneath entire industries. Building infrastructure means creating platforms that other businesses rely on to operate, scale, and innovate. I enjoy the challenge of designing systems that must be reliable, extensible, and trusted, knowing that if done right, they quietly power thousands of downstream use cases.

Generalist. Builder.

A multidisciplinary technologist with years of experience across the software lifecycle. I've worked across product, design, engineering, infrastructure, and quality assurance, allowing me to build and ship end-to-end systems.

Loves to play video games

I enjoy playing Dota 2 and building cities in Cities Skylines 2.
