Events
Surreal
Underground Christchurch raves grew from physical street promotion, improvised venues and a willingness to build an audience outside established nightlife channels.

David Ruck is a Christchurch-based entrepreneur, sales-systems builder and digital operator. I have worked across hospitality, telecommunications, call centres, business data, media, websites, hosting and digital marketing, and my current focus is AI-assisted infrastructure and business discovery.

The recurring pattern
Disruption, before I ever used the word for it.
The strongest through-line in my career is not a job title. It is a tendency to notice when an accepted model no longer matches the audience, customer or technology, then build something around the gap.
Telecommunications
TelstraClear
I challenged the assumption that consumer telecom products needed expensive door-to-door sales and built a telephone-sales process around a different proposition.
Radio
PulzarFM After Dark
I pushed the late-night station sound harder, opened the booth to guest DJs and argued that the real audience was younger and more male than management believed.
Business infrastructure
0199 → GRID EATER
Directory assistance became websites, hosting and business data. The same instinct now sits behind a leaner AI-assisted infrastructure model.
Selected brand experience
Recognised brands. Systems, not just job titles.
Hotel Dynamics Group taught me disciplined high-conversion telephone selling. TelstraClear gave me a chance to redesign a sales channel. HRV became another exercise in scripting, closing, team performance and outbound process.
The common thread
Find the real market. Build the system around it.
Sales, radio, live events, directories and technology look unrelated until you reduce them to the same problem: who actually wants this, what are the incumbents misunderstanding, and what happens if you remove the friction?
That approach took me from telephone sales into call-centre systems, from 0199 Directory Assistance into websites and hosting, and now into GRID EATER, business data and AI-assisted infrastructure.
Current focus
Infrastructure, data and AI.
I am combining decades of sales and digital experience with modern AI-assisted development to build faster, leaner systems for business discovery, websites, hosting and data.
2011 onward
0199
I built a Wellington VOIP call-centre and directory-assistance competitor, then used those customer relationships to move into websites, email, hosting and digital services.
Across three decades
Career
Hospitality, music, events, direct sales, telecommunications, call centres, media, websites, hosting, data and AI became parts of one unusually broad working life.
2026
GRID EATER
I am applying the same instinct to business discovery and digital infrastructure: expose unnecessary cost, automate repetitive work and own more of the underlying system.
“The industry changes. The instinct stays the same: question the assumption, find the audience, build the better route.”
