Growth & Marketing Leader
I'm a growth leader with over a decade of experience driving acquisition, retention, and revenue growth for technology companies across agtech, music, and healthcare — from early-stage startups to global platforms serving millions.

Partnered with high-growth startups across agtech, fintech, and music technology to unlock sustainable growth. Highlights included returning to Halter—now a billion-dollar unicorn—to define early go-to-market strategy for their U.S. expansion, sharpening positioning for American audiences and building systems to improve pipeline health and conversion. Also supported Yonda (gamified mobile app helping Kiwis improve their credit scores), New Zealand Mint (precious metal collectibles), and My DJ Cloud (cloud backup for professional DJs).

Drove early-stage growth for New Zealand's breakthrough agtech company, now valued at over $1 billion. Halter's smart cow collars and "cowgorithm" technology enable farmers to virtually fence, move, and monitor cattle—saving 20-40 hours per week while improving animal welfare and pasture utilization. Helped establish the foundation for expansion across New Zealand, Australia, and the United States.

Five years building and leading marketing at the Auckland-founded DJ software company that became the global industry standard. Serato's technology revolutionized digital DJing, with products used by artists from DJ Jazzy Jeff to Kanye West. Led integrated campaigns across multiple countries, developed management capabilities, and delivered significant shareholder value during a transformative period for the company.
Music TechnologyPhilosophy
My career is defined by a focus on customer insight, experimentation, and bridging product and marketing to unlock scalable, sustainable growth. I believe the best marketing is invisible—it's about understanding what customers need and creating systems that deliver value at every touchpoint.
From launching new ventures to navigating complex international markets, I bring a strategic, data-driven approach to every challenge. Whether embedded full-time or partnering as a fractional growth lead, I'm drawn to companies building products that genuinely transform how people work—whether that's farmers managing their herds, producers selling their beats, or clinicians caring for their patients.
I've had the privilege of working with globally distributed teams serving customers across every continent, helping scale products from local launches to international expansion.
