How AI, Blockchain, and the “Iron Man” CFO Are Reshaping Private Wealth — Darren Ng of WRISE

Darren Ng’s career trajectory is a blueprint for the modern, entrepreneurial CFO. After a decade in “well-oiled” global banks, he took a leap into the startup world as the first hire for Sea Group in Jakarta, where he helped acquire their first bank. This shift from governance-heavy environments to private equity and crypto co-founding reshaped his perspective on what a finance leader can achieve. Today, as Group CFO of WRISE, Darren bridges the gap between traditional wealth management and the agent-first future. He believes that the only way to survive the coming disruption is to proactively walk the talk and help colleagues transition into their own second careers.

Why should the modern CFO aim to be “Iron Man”?

Darren explains how AI acts as a productivity suit, allowing one person to manage the functions of a full department.

“Through my journey in crypto and FinTech, I have seen how technology magnifies productivity exponentially. Leveraging AI allows a CFO to wear multiple hats simultaneously: fundraising, M&A, and Investor Relations. I often tell people that with these gadgets and superpowers, you become like an ‘Iron Man’ in the finance world, one person capable of doing the work of an entire team. It gives you the capacity to do a lot more than just traditional financial controlling; it allows you to be an architect of the entire business model.”

How does blockchain move from speculation to infrastructure?

Darren clarifies his bullish stance on Ethereum, comparing it to the essential oil that fuels the global financial engine.

“Crypto started with a lot of speculation, but few people understood the actual use case. Blockchain is essentially a transfer of value. If Bitcoin is ‘digital gold,’ Ethereum is ‘digital oil.’ It is the payment infrastructure. Wall Street banks are already proclaiming that they will move their core banking infrastructure to the blockchain because it makes international transfers instant and removes intermediaries. In five years, I have no doubt that demand for these tokens will be sustainably higher than it is today as they become the backbone of global value transfer.”

Why is the era of Copy and Paste Associates over?

Discussing the disruption of junior roles, Darren highlights how AI and smart contracts are removing the middleman.

“Disruption to the workforce is coming fast. We used to joke that CPAs stood for ‘Copy and Paste Associates,’ but those days are over. In the past, banks had massive teams just to move data into reports. Now, SAP has AI modules that prepare comparative financial reports in seconds.

The same applies to smart contracts. If a loan contract is on a blockchain, the disbursement is automatic and rules-based. You suddenly don’t need that entire unit of people handling disbursements. AI can handle the first draft of legal contracts or financial audits, meaning you need a legal expert to review, but you no longer need a full team of juniors to do the groundwork.”

How do you teach the unlearn and relearn mindset?

As an adjunct lecturer, Darren pushes his students to abandon traditional business rules to understand asset-light platforms.

“I want my students to adopt a mindset where they learn, unlearn, and relearn. If you only follow the rules of a traditional business, like running a physical supermarket, you can never break the mould to build an asset-light platform like Alibaba or Airbnb. You have to be willing to unlearn the concepts you were taught years ago to understand how technology disrupts a traditional cost structure. It’s about making the technical bits relatable and captivating through ‘battle stories’ rather than just reciting a textbook.”

What is the “battle story” approach to leadership?

Darren argues that effective storytelling is the only way to make technical disruptions feel real to investors and teams.

“To be an effective storyteller, you need a wealth of experience. Like a musician who has to live life before they can write an album, a leader has to experience the struggle before they can tell a compelling story. When I tell my students that it costs a bank $100 to process a physical cheque, they finally understand why branches are disappearing and being converted into sales hubs. Storytelling is about making the technical RELATABLE. I use real-life examples of how I lived through these disruptions to raise funds and inspire my teams.”

What question should we ask our colleagues today?

In a final challenge to senior leaders, Darren shifts the focus from technology back to the human element of the workforce.

“I would ask: ‘How are we preparing our own staff for the new age of working?’ We cannot stand still. The AI wave is disrupting every industry. We have to help our people become more effective workers by embracing these tools. Beyond just being employees, these people are our colleagues and friends. We must help them think about their second careers and how they can move beyond their comfort zones to thrive. We have to demonstrate that an audacious dream can be achieved even as the environment shifts beneath us.”

Join the Conversation: The Ortus Club’s Executive Network

Across Darren’s insights on “Iron Man” finance, the Ethereum infrastructure, and the “Copy and Paste” disruption, one pattern is clear: these challenges aren’t solved in isolation. They require a peer-level perspective and the kind of high-trust dialogue that transcends traditional financial controlling.

His vision of the CFO as a storyteller reflects a broader reality: today’s finance leaders cannot rely on internal data alone. The most effective executives, especially those navigating the shift from legacy banking to blockchain-native platforms, actively seek out peer dialogue as a strategic necessity to unlearn the past.

At The Ortus Club, we host curated executive roundtables that bring together senior leaders facing these exact challenges. Step away from the traditional cost structures and engage in the kind of open, high-value conversations that help you relearn the rules of the new age of working.

Frequently Asked Questions

Q: What does it mean to be an “Iron Man” CFO?

A: It refers to a finance leader who uses technology (AI, automation, advanced analytics) to exponentially increase their productivity, allowing them to manage complex tasks like M&A and fundraising solo.

Q: Why is Ethereum called Digital Oil?

A: Unlike Bitcoin, which is seen as a store of value (gold), Ethereum is a programmable blockchain. It provides the “fuel” for smart contracts and decentralised applications that run global financial transactions.

Q: What is a smart contract in banking?

A: It is a self-executing contract with the terms of the agreement directly written into code. It allows for automatic actions, such as releasing loan funds once certain conditions are verified, without human intervention.

Q: How can a leader encourage unlearning?

A: By challenging long-standing business assumptions and encouraging teams to look at asset-light competitors. It involves prioritising new, technology-driven logic over traditional brick-and-mortar rules.

Q: Why are bank branches being converted into Sales Hubs?

A: As AI and blockchain handle the $100-per-cheque administrative costs of traditional banking, physical locations are shifting away from processing and toward high-value human interaction and sales.
