Build global
from day zero.
I'm Matt Ainsworth. Global Day Zero is my platform for founders ready to think and build beyond their own borders · not just their home market.
An idea you believe in · built to travel.
Most early founders build for home by default, not by design. The Global Day Zero Sprint takes a vague, home-only idea and makes it clear, proven, and ready to scale globally · in eight weeks, with a cohort beside you.
Most early founders are stuck the same way · conviction without proof, a home-only lens they've never questioned, and no tangible thing to put in front of anyone.
Some have already jumped to building · poking at tools before they'd defined or validated anything. So we start fresh: clarify, validate, scope globally, and only then build · on a foundation that's actually solid.
- All 8 weekly live cohort sessions
- Every framework, worksheet & action log
- The cohort room · ask, share, learn alongside other founders
- Async Q&A between sessions
- 4 × private 1:1 sessions with Matt
- One every two weeks across the program
- Direct, applied guidance on your own idea
- Warm intros where relevant
Are you building beyond your own borders?
Most AU and JP founders build domestically by default · not by design. Five questions to find out where your idea really belongs.
Building global from day zero.
Sydney to Tokyo to Perth and back. Twenty years at the intersection of startups, community, and commercial growth across both markets.
Matt Ainsworth is the founder of Global Day Zero. Born in Sydney, eight years in Tokyo, a stretch in Perth · back on the East Coast since early 2025. I've spent my career helping founders build things that travel across borders, not just markets.
I lead Innovators Campus, a startup education and storytelling platform bridging Australia and Japan, and host the 13,000+ member AU × JP Startups community. I'm also building a global accelerator program connecting founders across both markets. I've mentored 150+ founders across Sydney, Perth, and Tokyo, and worked alongside VCs including Timee, DeNA, ANRI, and CyberAgent Capital.
From founders I've worked with.
I came to Matt @ Innovators Campus as a founder with ideas but not yet the confidence to articulate them clearly. What I found was a room full of people who genuinely wanted each other to succeed · and an environment that made it safe to be a work in progress. The feedback I received on my pitch was specific, honest, and immediately actionable. I left with a sharper message and a clearer sense of what I’m actually building.
Matt is truly intelligent, well-traveled, and highly experienced in both Japan and Australia. With his business background, cultural understanding, and tech-savviness, he mentored me to establish my business in Japan and expand to Australia in less than a year.
Matt is a great and responsible person to work with. I tried different coaches before but he is the best · I got a lot of insight every session. If you work with him, I promise you will develop some great outcomes.
