Good to Great
Making good businesses greater

We use IT to bring together potential providers and consumers by matching supply and demand.
We bring the “blessed rain”. That is our mission.


By bringing together scattered supply and potential demand, we can aid both.

Rainmaker Inc. is a private company whose mission is matching supply and demand, potential providers and consumers via IT solutions, bringing the “blessed rain” to both.” We aim to turn nothing into something, ordinary to good, good into great. Bringing the “blessed rain” by matching supply with demand is our guiding North Star. Until we reach that bright light, we will keep challenging ourselves through trial and error, working towards our goal with commitment and persistence.

Demand mining marketing system

The goal of marketing is to identify and correct mismatched supply and demand, bringing balance to trade. In order for that to happen, the perceived demand will have to be based on the actual demand. Being confident in our abilities to mine out the actual demand on the market, we have adopted a 0 yen success fee policy for your first demand mining request.
