We Help Extraordinary People Build A Better Future



Coral Capital is a seed to early stage venture capital firm investing in the top entrepreneurs across all industries, from fusion engineering to SaaS. With about $300m under management, we have invested in over 80 companies including SmartHR, KAKEHASHI, Logiless, Kaminashi, Graffer, and Pocket Concierge (acquired by American Express). 

We launched our first fund in partnership with 500 Startups, a Silicon Valley based firm and one of the most active investors in the world. Given our Silicon Valley roots, we were the first to introduce many concepts in Japan, including convertible equity (J-KISS), and the startup market’s first SPV. Although we are no longer affiliated with 500 Startups, we still maintain a global network of investors, some of which are LPs in our funds. 

In addition to capital, we manage one of the most engaged communities of founders and startup employees in Japan. We also run the most widely read VC blog and the largest startup career fair in the country, both of which drive thousands of candidates to our portfolio companies to hire each year. 

We believe that the greatest companies are built by founders, not investors. The founders we invest in are exceptional without our help. Our job is to be their multiplier. We help them go faster and go bigger, while giving them the space to build their companies as they see fit. We are not “hands on” investors nor “hands off” investors. We are “hands-if” investors. As in, “call us IF you need us.” We are there when you need us, and out of your way when you don’t.
