Diffblue

Diffblue drives velocity, quality, and productivity for Java development teams working on mission-critical applications. Its flagship product, Diffblue Cover, leverages generative AI to automate unit test generation 250x faster than a human developer. As a result, software teams can improve code quality, expand test coverage, and increase efficiency so they can ship software faster, more frequently, and with fewer defects. Diffblue’s novel generative AI approach leverages reinforcement learning techniques to avoid the accuracy, security, privacy, and liability concerns associated with LLM-based coding assistants. Diffblue, whose customers include JP Morgan, Cisco, Citi, AstraZeneca, ING Australia and BNY Mellon, is a Gartner Cool Vendor in Agile and DevOps.
