The Fintech Founder Who Wants to Replace Your Bank

November 22, 2025

London’s $10 Billion Man, Alex Ng, on the Future of AI in Finance

In the heart of London’s vibrant Shoreditch tech hub, a financial revolution is quietly brewing, led by a figure challenging the very foundations of traditional banking. Meet Alex Ng, the dynamic 32-year-old CEO of Vault, London’s fastest-growing fintech unicorn. With a dazzling $10 billion valuation, Vault isn’t just seeking to compete with banks—it aims to replace them entirely.

Ng is leveraging the power of generative AI to shake up the financial world, offering a new breed of personalized financial advice that goes far beyond generic algorithms. Vault’s core innovation lies in its ability to use AI to understand individual financial patterns, predict needs, and offer bespoke strategies previously only accessible to high-net-worth clients.

The London Advantage and Regulatory Maze

In an exclusive cover story, Ng opens up about the journey of scaling a $10 billion company in a demanding global landscape.

• Navigating Global Regulations: A significant portion of the interview focuses on the complex challenge of navigating disparate global regulations. Ng emphasizes that building a replacement for the banking system requires ironclad compliance across multiple jurisdictions—a feat only achievable with cutting-edge, transparent AI governance models.

• Why London? For Ng, London is not just home; it’s the best city to launch a financial revolution. He champions the city’s unique blend of deep financial talent, a forward-thinking regulatory environment (often cited as a key enabler of fintech), and proximity to global capital. The sheer density of innovation in areas like Shoreditch provides the ideal incubator for a company like Vault.

AI, the Future of Finance, and ‘Crypto Maximalism’

The conversation shifts to the future, with Ng firmly planting his flag on the role of AI in finance. He envisions a future where financial wellness is not a luxury but an AI-driven default, making financial planning seamless and intuitive.

However, it’s his controversial stance on ‘crypto maximalism’ that is likely to draw the most attention. While Vault uses advanced digital technologies, Ng offers a critical perspective on the maximalist view that only fully decentralized cryptocurrencies can be the future, suggesting a more balanced, regulated, and AI-integrated approach is the pragmatic path to mass financial disruption.

Ng’s journey underscores the UK’s position as a global finance technology powerhouse. Vault’s $10 billion valuation is, in the CEO’s own words, “just the beginning.” It signals a paradigm shift where AI is set to become the primary interface between individuals and their wealth.
