Liquid Instruments, a San Diego-based provider of software-defined test solutions, has raised $50 million in a Series C funding round.

The round was co-led by Keysight Technologies and the Australian Government’s National Reconstruction Fund Corporation (NRFC). In addition, Keysight plans to enter a commercial partnership with the company. This collaboration aims to support the development of AI-driven instrumentation.

Focus on AI Platform and Key Industries

The company will use the new capital to accelerate product development. Moreover, it plans to scale its AI-powered platform and expand its go-to-market efforts.

Its primary focus areas include aerospace, defense, and semiconductor industries. These sectors require advanced testing solutions, which aligns with the company’s offerings.

Software-Defined Approach to Test and Measurement

Founded by CEO and co-founder Daniel Shaddock, Liquid Instruments develops software-defined instrumentation. Its platform combines hardware with software to streamline testing processes.

As a result, engineers can replace multiple traditional instruments with a single, reconfigurable device. This approach simplifies workflows and improves efficiency.

Currently, the company serves thousands of users globally. Its customer base spans aerospace and defense, semiconductor, and quantum research sectors.
