CHEMICAL ENGINEERING + PERFORMANCE MARKETING

I Treat Advertising Like a System. Because It Is.

My background in chemical engineering shaped how I approach performance marketing: understand the system, identify the constraint, test, measure, improve.

Today, I bring that same thinking to Google Ads, Meta Ads, CRO, tracking, and attribution – with 7+ years in paid media and $53M+ in managed ad spend.

I am not just looking at clicks and platform metrics. I first want to understand how the business makes money – the offer, ideal customer, economics, and sales process – then where the acquisition journey breaks down.

MEET THE FOUNDER

Meet Sim, Founder of Adstack.

A quick introduction to the thinking, experience, and approach behind Adstack.

SYSTEMS THINKING FOR REAL BUSINESS GROWTH

Before I Optimize an Ad, I Want to Understand the Business.

Chemical engineering taught me to work through problems systematically: understand the system, identify the constraint, test, measure, and improve. I bring that same process to marketing.

Before changing campaigns, I want to understand the offer, ideal customer, customer value, margins, which services or products matter most, lead quality, sales process, and follow-up. Sometimes the ads aren’t the problem.

Once those pieces are clear, Adstack can diagnose where the acquisition journey is breaking down and make better decisions across campaigns, tracking, landing pages, CRM, lead quality, bookings, sales, and revenue.

It's a system, not just ads.

A COMPLETE SYSTEM, NOT JUST ADS

I Don’t Just Manage Ads.
I Look at the Whole Acquisition System.

A successful campaign doesn't start with traffic. It starts with understanding the business behind it, what is being sold, who the best customer is, what they are worth, and how the business turns an enquiry into revenue.

Once that is clear, Adstack can make better decisions across the full customer acquisition process.

TECHNICAL EXPERIENCE

Better Decisions Start With Better Data.

When tracking is incomplete or disconnected from your business, even a well-performing campaign can be difficult to evaluate.

I work across the measurement and integration tools that help connect advertising activity with customer outcomes.

The goal is simple: understand where your customers come from, what happens after they click, and where your marketing can improve.

AN ADDITIONAL PERSPECTIVE

Understanding What Makes People Buy.

Outside performance marketing, I've also worked in commercial modeling and brand campaigns. That has given me another perspective on how presentation, trust, aspiration, and visual positioning influence the way people perceive brands.

That perspective is particularly relevant to aesthetic clinics, wellness businesses, fashion, beauty, and other image-led industries.

It's another way I look at the customer journey, beyond the numbers alone.
