Graphcore
HiringGraphcore is a Bristol-based AI semiconductor company founded in 2016 by serial semiconductor entrepreneurs Nigel Toon and Simon Knowles. Toon previously led XMOS and Picochip, while Knowles co-founded Element14 (acquired by Broadcom) and Icera (acquired by NVIDIA for $435M). The company developed Intelligence Processing Units (IPUs), novel AI accelerators designed from the ground up for machine learning workloads, alongside the proprietary Poplar graph programming framework. Graphcore raised $767M in total funding, reaching a $2.77B valuation, with backing from Sequoia Capital, Atomico, Amadeus, Microsoft, and others. In July 2024, SoftBank Group acquired Graphcore for approximately $500M to $600M. The company continues to operate from Bristol with plans to expand its UK headcount to 750.
PhysicsX
PhysicsX was founded in 2020 in London by Robin Tuluie and Jacomo Corbo, both veterans of elite motorsport engineering. Tuluie previously led R&D at the Mercedes and Renault (Alpine) Formula 1 teams and served as Vehicle Technology Director at Bentley, while Corbo co-founded QuantumBlack (later acquired by McKinsey) and worked as a Formula 1 chief race strategist. The company builds an AI-native simulation platform that embeds physics neural operators directly into engineering workflows, predicting how products will behave in seconds rather than the hours or days traditional simulation demands. PhysicsX serves aerospace and defence, semiconductors, automotive, materials, and energy customers, and has partnered with Siemens and NVIDIA on data centre power infrastructure. The company has raised more than $450M to date, including a $135M Series B led by Atomico in 2025 and a £225M Series C led by Temasek and M&G Investments in 2026.
