A NOTE FROM OUR FOUNDER

The Opsize Story..

Hi! I'm Kev.

Ever wondered how a humble burger joint becomes a global behemoth like McDonald's?

Throughout my career, I’ve been fascinated by that very question.

And after years in the entrepreneurial kitchen—7 businesses later and 250+ founders coached—I can tell you, the secret ingredients are simple:
🍔 ambitious goals,
🍔 an unrelenting will to succeed, and 
🍔‍ finely-tuned systems
to get you there.

I left the Investment Banking world over a decade ago, stepping into the vibrant (and at times gruelling) world of tech startups.

It’s been a tough but sweet ride—and I’ve tripped and fallen more times than I care to count.

But every stumble was a lesson, a flavour note, in the art of running a business.

Because just like crafting the perfect recipe, you learn more from your entrepreneurial missteps than your wins.

And every misstep gets you one step closer to success.

After two decades building, scaling and coaching startups, I’ve been lucky to have a few wins.

From bootstrapping businesses from scratch to raising tens of millions in venture capital, to scaling startups from Sydney to San Francisco and beyond—I've had my fair share of entrepreneurial servings.

I love sharing those learnings with founders.

I’ve personally advised and mentored over 250 of them—and I’m passionate about helping them avoid the common pitfalls, and instead, find the fastest path to traction.

But there’s one thing that’s always bugged me..
