Hamachi

Hamachi was one of three Japanese investment consortia and underwriters that helped fund International Genetic Technologies. According to Donald Gennaro, InGen's legal counsel, Hamachi was one of their principle supporters, and were the main company that began growing uneasy in 1989, after the deaths of several workmen. As a result, they demanded an on-site inspection, resulting in the Isla Nublar Incident. Apparently, they also manufactured InGen's Hamachi-Hood Gene Sequencers for their genetic labs as mentioned in both the first and second novels.
