Overview

Samuel Loo and Singchuen Chiam transformed a high‑school hobby into a dominant Amazon matcha brand by pairing their personal chemistry with a rigorously data‑driven growth playbook. Their approach, which blends low‑risk market testing, precise listing optimization, and direct sourcing, now secures top positions in the green‑powder category and offers a repeatable template for sellers in any niche.

Key Points

• Early experimentation — While still attending high school, the partners used a modest home kitchen to blend several matcha formulations, documenting flavor profiles and cost structures in a shared spreadsheet.
• Rapid Amazon entry — Within three months of graduating, they launched their inaugural product, earned the “Amazon’s Choice” badge for the keyword “organic matcha powder,” and saw the listing climb to the first page of search results.
• Targeted keyword expansion — Six months after launch they introduced five long‑tail keywords—such as “ceremonial grade matcha” and “matcha latte mix”—each aligned with a distinct consumer intent, expanding organic traffic by a measurable margin.
• Direct farm partnership — By negotiating a purchase agreement with a reputable Japanese tea farm, they removed intermediaries, lowered unit cost, and gained control over quality certifications, which they highlighted on the product detail page.
• Packaging redesign driven by reviews — Analysis of more than 120 customer reviews revealed recurring complaints about pouch resealability; the team responded with a resealable, foil‑lined pouch that cut return rates and boosted repeat purchases.
• Advertising shift to exact match — Weekly performance audits prompted a migration from broad‑match to exact‑match Amazon PPC campaigns, increasing ad‑spend efficiency and raising the return on ad spend (ROAS) to double‑digit percentages.

How Their Growth System Works

1. Validate demand with micro‑testing — The duo ordered a limited batch of ceremonial‑grade matcha, created a simple product page, and ran a two‑week giveaway that attracted 1,200 participants; the conversion data from the giveaway confirmed sufficient demand before committing to larger inventory.
