About

I’ve been where you are. Here’s how I got out.

I know what it feels like when your company grows faster than your ability to lead it.

In 2010, my sister and I started GetCre8ive, then co-founded StraightArrow. Within a few years we had 40 marketing specialists serving clients across the US, UK, and Australia. On paper, we were winning. Inside, I was drowning.

EOS changed that. We grew 5x. I stopped being the bottleneck. In 2023, StraightArrow was acquired by 2X.

I became an EOS Implementer because I wanted other founders to find that clarity faster than I did. Today I'm an Expert EOS Implementer® & the Master Franchisee for EOS Worldwide in the Philippines, with interim stewardship of Singapore. I've worked with over 120 leadership teams across eight markets.

I'm also an EO Forum and Accelerator Trainer for EO Singapore and EO Indonesia, an Agora Award recipient for Entrepreneurship, and the author of The 90-Day Leadership Field Manual — the book I wish someone had handed me when I was suddenly expected to lead with zero support.

Everything I do comes back to one thing: founders and the people who lead alongside them deserve better systems and a steadier path.

EOS Implementation

Get what you want from your business

EOS gives your leadership team a shared language, a clear plan, and the discipline to actually follow through. Thousands of companies run on it. Here’s why.

Vision

Everyone knows where you’re going and how you plan to get there. No more guessing.

Traction

Your team executes on what matters — every week, every quarter. Fewer fires. Better decisions.

Healthy

A leadership team that trusts each other, resolves issues fast, and actually enjoys the work.

The first step is a free 90-Minute Meeting. No pitch, no pressure — just an honest conversation about where your business is and whether EOS can help.

“In a 60+ year old business, change is hard. I tried other frameworks — none stuck. EOS is simple but complete. Leadership is now aligned.”

Alick Koo

CEO, UCP Group ↗

“In 2022, we were stuck — focusing on too many things. Today, we have an engaged team with clear roles and we’re on track for ₱1B by end of 2025. Ia is a wonderful facilitator and trusted partner.”

Who it's for

First-time leaders, HR/L&D professionals, entrepreneurs who became bosses overnight, and coaches seeking a practical framework.

Endorsement
