10 times more convenient, 10 times more useful

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


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

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.

Takeshi Okano


We are a web marketing business working to extract user demand.

The goal of marketing is to identify mismatched supply and demand and implement a 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 requested 0 yen initial cost and adopted a pay-per-success model.
