University of Bristol-founded voice and intelligent control semiconductor developer Xmos has increased its total funding to $91m following a $19m round.

Xmos, a UK-based fabless semiconductor developer spun out of University of Bristol, has closed a $19m round involving undisclosed existing investors. The round consisted of an unspecified mix of equity financing and venture debt, with the latter supplied by Harbert European Growth Capital. Founded in 2005, Xmos focuses on voice control and audio components for consumer electronics products that enable users to interact with devices by speaking to them. The company’s product line includes hardware tools which help develop apps for voice-controlled smart assistants, as well as silicon voice processors equipped with a range of microphone, processing and connectivity enhancements. The capital will fund work on additions to Xmos’s product portfolio with the aim of broadening its roadmap to incorporate more applications exploiting artificial intelligence. The spinout will also hire more staff and drive its international expansion efforts. Xmos has now collected $91m in total funding. Semiconductor maker Infineon Technologies led a $15m series E round in 2017, which featured Robert Bosch Venture Capital (RBVC), the corporate venturing subsidiary of industrial product maker Robert Bosch, as well as Amadeus Capital Partners, Draper Esprit and Foundation Capital. Xmos received $26.2m in an RBVC-led series D round in 2014 that was backed by telecoms equipment producer Huawei Technologies, chipmaker Xilinx, Amadeus Capital Partners, DFJ Esprit and Foundation Capital.
