A UK-incorporated chip company, with a London office, that designs the very fast connection technology used to move data in AI and cloud data centres.
Alphawave Semi designs the technology that moves data very quickly between chips, and between computers, inside data centres. Its own description is that it is a semiconductor company specialising in high-speed wired connectivity and compute technologies. It is a fabless company, which means it designs chips and chip building blocks and uses specialist factories to make them. Its annual report for 2024 lists more than 240 silicon intellectual property products (reusable chip designs sold to other companies), custom chips, connectivity products and chiplets, which are small chips that can be combined into a larger one. Its work supports data centres, artificial intelligence and digital infrastructure.
The company says its purpose is "pioneering connectivity technology to enable a new era of accelerated computing". Its stated ambition is to become the leading semiconductor company in wired connectivity and compute for AI and digital infrastructure. Its values, as listed in the report, are collaboration, innovation, openness, integrity, inclusivity, and awareness of its impact on society and the environment. Alphawave was founded in Toronto in 2017 and has been incorporated in the UK since December 2020. Tony Pialis is its chief executive and co-founder. The company was bought by Qualcomm in a deal that closed in late 2025, and Mr Pialis was reported to be leading Qualcomm's data centre business.
The company's UK link is real but modest in size. It moved its headquarters to London when it listed on the London Stock Exchange in 2021, although Toronto remained its main engineering base. In 2021 its executives said they planned a design centre in Cambridge, with hopes of about 100 engineers in a few years, and that they hire in teams of 20 to 30 people. Its 2024 annual report lists London among its offices, but does not mention Cambridge, and says only 9% of its roughly 1,000 staff worldwide were in Europe, the Middle East and Africa. We could not confirm how many people work in the UK today.
On culture, the annual report says the company is certified as a Great Place to Work in its main locations, runs leadership training and mentoring, and takes part in STEM outreach programmes. It reports that women made up 19% of its workforce, that staff turnover was 9%, and that it took on 68 interns in 2024, in Canada and India. Those are the company's own figures. As a business that works with major chip makers such as TSMC, Samsung and Arm, it has a technical and international culture.
Jobs at a company like this include chip designers, verification engineers, software and firmware developers, applications engineers who help customers use the products, and finance, legal and human resources staff. Maths, physics, electronics and computing are the usual starting points. Because ownership has changed, check the company's website, and Qualcomm's, for how its UK teams are organised now.
