Fit.
It’s Personal and Powerful.
Marketing dollars vanish in broad campaigns.
Returns quietly erode your bottom line.
Automation tools fail to decode what really matters.
What others missed is now our foundation
where trust, fit, and real choices intersect.
No guesswork.
No generic trends.
Just smarter, Context-Aware Targeting.
Because One-Size-Fits-All marketing doesn't work.
Marketing based on assumptions belongs to the past.
Now, it’s about knowing what actually drives conversion.
Built by Insiders. Made to Scale.
Ashley Sung, Founder & CEO
From Experience to Execution
Ashley didn’t just work in fashion. She lived its flaws at every level.
At Amazon and Walmart, she saw great campaigns collapse from poor sizing.
At Shopbop and Men’s Wearhouse, she managed buying and returns, seeing how size uncertainty crushed margins.
At Calvin Klein, Lacoste, and Moncler, she learned how fit disrupts supply chains.
At Valentino, she saw how it quietly erodes brand trust.
Then it clicked:
When fit fails, everything else collapses.
Sizing isn’t just a UX issue. It’s a $100B return crisis in fashion e-commerce. Predictive tools failed, because fashion never needed more guesses. It needed better understanding.
That’s why she built Sizepia, a scalable sizing platform powered by fashion expertise and operational depth that boosts conversion, and cuts returns.
As CEO, she brings more than vision. She builds systems, executes with precision, and delivers results that move the needle.
She drives smarter brand growth by adapting insider insights to the fit challenges of each region from New York to Asia to Europe.

The Strategist Who Turns Insight into Impact
Chulho doesn’t just advise. He architects strategies that scale, grounded in insight, shaped by creativity, and protected by foresight.
With deep experience across fashion, outdoor, and retail, he led breakthrough repositioning campaigns for Marmot (US), Berghaus (UK), and Lyle & Scott (UK), each defined by emotional clarity and measurable results.

He brought a classical concert to the top of the Himalayas. Not a stunt, but a strategy that turned Orange Factory into a bold, unforgettable brand across national media.
Before consulting, he was a journalist trained to detect early signals before they became market shifts. Today, he applies that instinct to brand evolution and go-to-market execution.
At Sizepia, he turns raw fit data into sharp strategy: smarter positioning, stronger brand trust, and cross-border growth, all with commercial rigor and built-in risk controls.
He turns insight into traction.
Traction into scalable, defensible brand value.
Guesswork belongs to machines.
Smart brands choose human insight.
