What Quartet FS does
Azul Systems, Inc. is a privately held Java platform company founded in 2002 and headquartered in Sunnyvale, California, that operates as the world's largest independent Java vendor with 100% of its business focused on Java. The company builds and sells two complementary runtime platforms: Azul Platform Prime, a high-performance JVM featuring the patented C4 concurrently compacting garbage collector and the LLVM-based Falcon JIT compiler (with ReadyNow! warmup optimization), and Azul Platform Core, a commercially supported OpenJDK distribution built on Azul Zulu. Both are complemented by Azul Intelligence Cloud, a SaaS analytics layer providing JVM inventory, vulnerability detection, and code inventory across the enterprise Java estate. Sub-brands include Azul Payara Micro (cloud-native microservices runtime) and Azul Payara Server (Jakarta EE application server).
The company monetizes through annual subscriptions to its Java runtimes, professional services for Oracle-to-OpenJDK migration, and SaaS subscriptions to Azul Intelligence Cloud, with distribution through direct enterprise field sales, a global PartnerConnect network of VARs/distributors/MSPs, and AWS and Google Cloud Marketplaces. The customer base is concentrated in large enterprises — Azul claims 37% of the Fortune 100, 100% of the top 10 global trading firms, and 12% of the Global 1000 — with named logos spanning financial services (Mastercard, HSBC, Bank of America), technology (Workday, Salesforce, Adobe, Netflix, Lyft, Taboola), retail (Priceline, Puma), and other verticals. Headcount is reported in the 101–250 range, with global operations spanning North America, EMEA, and APAC.
The fundamental value proposition is replacing Oracle Java subscriptions with a drop-in, supported OpenJDK alternative while delivering measurable performance and cloud-cost improvements — claimed reductions of up to 70% in Oracle licensing costs and up to 50% in cloud infrastructure spend, with Forrester TEI studies reporting 129–224% ROI and customer-documented outcomes of hundreds of servers eliminated. Azul has no parent company, no disclosed institutional investors, and no publicly disclosed revenue or funding history, operating as a closely held independent firm.
