11x
11x is the breakout star of the UK's agentic AI wave, known for building "digital workers" that replace full job functions rather than merely assisting them. Founded in 2022 by Hasan Sukkar, the company frames its product as autonomous employees rather than software tools. That positioning is controversial, but it resonates with revenue teams seeking to eliminate manual drudgery and scale outreach without linear headcount growth. The flagship product, Alice, is an AI Sales Development Representative that can source leads, research accounts, craft highly personalized outreach, and follow up continuously. In late 2024, 11x launched Jordan, a multilingual AI phone agent that conducts real-time voice conversations for qualification and support in more than 30 languages. Together, these agents can run a large portion of the outbound funnel end-to-end, from initial outreach to handoff, with human oversight focused on high-value exceptions. By early 2026, 11x had exploded in valuation after a Series B led by Andreessen Horowitz, a rare win for a UK-first startup. The company processes millions of interactions for high-growth tech companies such as Otter.ai and Airwallex and is expanding its footprint in San Francisco to preempt US-based competitors. The roadmap centers on "digital teams" that coordinate multiple agents across tasks: one agent identifies a lead, another calls, a third negotiates logistics, and a final agent drafts the contract. This orchestration layer is the company's strategic bet on becoming the default system for revenue operations. The company's roots include Y Combinator's Summer 2023 batch, which accelerated its US network and credibility, and its UK engineering base sits in the London Bridge tech hub. Investor support spans US and European capital: a16z led the Series B, Benchmark led the Series A, Lux Capital participated early, Quiet Capital backed growth, and 20VC provided influential local support. In 2026, 11x is the UK's most visible play on AI-native revenue teams, aiming to become a category-defining platform for autonomous sales operations.

Cazoo
Cazoo was a London-based online used car platform founded in 2018 by Alex Chesterman, the serial entrepreneur behind Zoopla and LoveFilm. The company aimed to bring the Carvana model to Europe, allowing consumers to buy, finance, and have used cars delivered to their door. Cazoo went public via SPAC on the NYSE in 2021 at a valuation of around $7 billion and expanded aggressively into France, Germany, Spain, and Italy. However, rapid cash burn and a cooling market led to a retreat from continental Europe and a delisting from the NYSE in 2024. Cazoo's trajectory became a cautionary tale in European tech about the risks of capital-intensive consumer marketplaces scaling too fast.
