The Startup powering ANZ's Open Banking Moment

Hi TechMates Community,

🎙️ Hendrik Remigereau here—bringing you another frontier-building conversation, powered by NZVC, the venture firm backing the next generation of iconic companies from New Zealand and beyond.

In this episode, we sit down with Dermot Butterfield, who built the first version of his open banking platform, Wych, while bootstrapping and coding during his twin daughters' naps. Dermot opens up about the grueling reality of starting a fintech company from scratch, the global open data revolution, and how giving consumers control over their financial information changes everything.

In this episode, you’ll discover:

• 🌱 Pacing yourself: Why you have to pace yourself with enterprise sales because moving a massive financial institution is a slow, methodical process.

• 💡 Investor communication: How he learned that investors are just another type of customer requiring a completely different communication strategy than B2B clients.

• 🔥 Open banking: Unpacking open banking and how API pipes are finally replacing the risky practice of sharing banking passwords.

• 🌍 The expat advantage: The “Irish mafia” networking advantage and how Dermot navigated the tight-knit New Zealand ecosystem as an expat.

• 🚀 A weekend sprint: How he scored a massive win by rapidly rewriting his platform over a single weekend to land the Australian government as a test partner.

After taking a year off to be a stay-at-home dad, Dermot decided to go all-in on his startup. He put his mortgage on the line, fully realizing the massive stakes of his chosen industry. As he explains,

“You can’t MVP compliance. You’re either compliant or you’re not”

The true validation came when Dermot tested the prototype on his own family’s finances. The software uncovered multiple forgotten subscriptions, proving the immense consumer value of his product. He realized that open banking isn’t just about software integration; at its core

“It’s the idea that your financial data is yours”

Building Wych required immense personal sacrifice. To fund his growing team without taking a salary, Dermot worked three jobs simultaneously, enduring grueling 6 a.m. to 4 a.m. schedules. Reflecting on the heavy toll it took on his personal life, he confessed,

“I don’t have a personality anymore. I have a startup”

Today, Wych serves as the secure digital pipes connecting legacy banks with innovative financial services. By automating compliance and bypassing outdated screen-scraping methods, Dermot’s platform is finally breaking the built-in inertia of the traditional banking system.

True disruption requires unwavering conviction, even when you are building the future of finance from your living room.
