London, United Kingdom · Startup 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.

London, United Kingdom · Startup Revolut is a British fintech company offering a “super-app” for digital banking and financial services. Launched in 2015 by founders Nik Storonsky (a former Credit Suisse trader from Russia) and Vlad Yatsenko (Ukrainian developer), Revolut began as a multicurrency travel card allowing users to spend and transfer money globally with minimal fees. It quickly evolved into a full-featured neobank. As of 2025, Revolut operates in 48+ countries and has 65 million customers worldwide, making it one of the fastest-growing fintechs ever. The app provides a suite of services: GBP and EUR bank accounts, debit cards, currency exchange for 30+ currencies at interbank rates, stock and crypto trading, person-to-person payments, bill splitting, and more. Revolut’s growth has been astonishing – it surpassed £3.1 billion in annual revenue in 2024 with £1.1 billion operating profit. The company has raised over $1.7 billion from investors like SoftBank, Tiger Global, and TCV, reaching a private valuation of $33 billion in 2021.

Revolut’s mission is to become a “global financial super-app”, consolidating banking, investing, insurance, and payments in one place. It has introduced products like “Revolut Junior” accounts for kids, pay-later services, and expanded into credit in select markets.

London, United Kingdom · Startup Wayve is a London-based autonomous driving company built around the idea that vehicles should learn to drive through end-to-end machine learning rather than depend primarily on hand-coded rules and pre-mapped environments. That design choice makes Wayve one of the most important applied AI companies in Europe, because it pushes autonomy closer to a generalized intelligence problem than a traditional automotive software stack. By learning from raw driving data and behavior rather than fixed rulesets alone, Wayve aims to create systems that adapt more fluidly to unfamiliar roads and edge cases. This approach places the company near the frontier of embodied AI, where perception, planning, and action are trained together. In ecosystem terms, Wayve sits alongside Europe's most ambitious AI infrastructure and model-building efforts, but with a direct path into physical-world deployment through automotive and fleet partnerships. It is therefore a strong example of how European AI can move beyond content generation into safety-critical systems. The company also highlights London's role as a regional AI hub where capital, research talent, and commercialization pathways increasingly overlap.
