International growth, cross-border trade, and the systems behind them

I’m Ryan Sadamitsu. I’ve spent 15 years building e-commerce businesses where the standard playbook doesn’t work. Most recently I spent most of a decade running Japan for a global wellness e-commerce company, then helped set its international strategy across 50+ markets.

Today I’m working where AI meets international trade: building agent workflows that turn research-heavy, judgment-heavy cross-border work into systems that scale.

Open to advisory projects, contract roles, and good conversations.
