Case Study: ICHIGO Inc. achieves 30x creator growth and scales its affiliate program with GRIN

How a startup subscription box service leverages brand love to grow its affiliate program

ICHIGO Inc. is a Tokyo startup that shares Japanese culture worldwide through subscription boxes like TokyoTreat and Sakuraco. After launching an affiliate program in 2021 and hiring Clay Thomas to scale it, the company needed better ways to organize communications, generate and track affiliate codes, nurture long-term creator partnerships, and manage incoming creator content — so they turned to GRIN and its Creator Management platform.

GRIN’s all-in-one Creator Management platform handled outreach and recruitment, generated affiliate links at scale, and provided analytics to measure performance. The result: ICHIGO Inc. grew its creator roster 30x in a year, recruited and retained creators passionate about Japanese culture, and now executes multiple creator campaigns each month, delivering clear, measurable growth for the brand.
