BellSoft
BellSoft built a business around the part of Java most companies would rather not think about. Its pitch is simple: one engineering team for the runtime, the Linux layer and the container - with fewer licensing surprises and fewer vulnerabilities to chase.
Azul
Azul is the largest independent Java vendor and a major contributor to OpenJDK. It builds production-grade Java runtimes - Azul Platform Core (certified OpenJDK builds) and Azul Platform Prime (a high-performance JVM) - plus the analytics-driven Intelligence Cloud. Companies use Azul to escape Oracle Java licensing costs, run lower-latency applications, and cut cloud spend.
Scott Sellers
Scott Sellers is the co-founder, President, and CEO of Azul, the Sunnyvale-based company that has spent two decades making Java run faster, cheaper, and freer from Oracle's licensing grip. Before Azul, he co-founded 3dfx Interactive, the graphics company that gave PCs real-time 3D before NVIDIA bought it. Eight patents, a Princeton EE degree (magna cum laude, Phi Beta Kappa), and a backup-quarterback origin story round out a quietly relentless career.
Alexander Belokrylov
Alexander Belokrylov is co-founder and CEO of BellSoft, the San Jose company behind Liberica JDK and Alpaquita Linux. After nearly thirteen years inside Sun Microsystems and Oracle - shipping Java ME Embedded, evangelizing Java SE, running pieces of Oracle's IoT Cloud - he left in 2017 with a group of OpenJDK engineers and started building a downstream Java distribution that now runs on millions of servers and ships inside Spring's own quickstart.
