About us

Marketers +
engineers in one team

Led by a SET50-listed company executive & a Ph.D. advisor

OG Solution (formerly Marketing Expert) was founded by Mahidol BBA and Siriraj MBA alumni who believe Thai businesses should have access to world-class martech without hiring a foreign agency. We have served more than 300 businesses, from SMEs to large organisations.

Our values

We all work by the same principles

Result-driven

We measure everything in numbers — no work without a KPI.

AI-first

AI runs through every workflow so we ship faster and smarter.

Owner mindset

We work as if we owned our client's business.

Long-term

Roadmaps that go beyond the contract · a partner, not a vendor.
