I am a product of two distinct data cultures.

Born in Shanghai and raised in New Jersey, I built my foundation in the rigorous, structured machine of American enterprise analytics. I learned to find patterns in noise and make the invisible visible using Western methodologies.

But the real challenge began when I returned to Shanghai in 2012.

I walked into a digital explosion. While the West had Facebook and Twitter, China had built a dense, walled garden of super-apps: Weibo, WeChat, and eventually Xiaohongshu and Douyin. The ecosystem was faster, more chaotic, and completely opaque to the outside world.

I spent the next decade bridging that gap. I applied American data discipline to Chinese social velocity. I built topic models in R, LGBM models in Python, and manually deconstructed algorithms. I spent years building queries by hand, extracting data from the noise, and helping global beauty brands verify exactly what was being said about them in the raw, unfiltered stream of Chinese social media.

That accumulated knowledge is now Unrandom.

We help brands see exactly how their campaigns perform on Xiaohongshu and Douyin. Not vanity metrics or surface-level dashboards, but forensic verification: did the creator actually deliver the brief? Did they say the keywords? Did they show the product at the right moment? Our AI watches every frame, transcribes every word, and scores each post against your defined success criteria. The kind of audit that used to take hours of manual video review, done in minutes.

We built this for the agency teams who are tired of subjective interpretations and inconsistent reporting. For the brand managers who need to prove ROI to leadership, not just claim it. For anyone who has ever wondered whether a creator actually delivered what they were paid for, and had no good way to find out.

The days of trusting screenshots and taking creators at their word are ending. Brands want receipts. Timestamped, searchable, objective proof that the message was delivered as promised.

That's what we provide. Every frame. Every word. Every campaign.

Wendy was with Unrandom before Unrandom had a name.

It started with a phone call. I had just landed a major project with Amorepacific and needed a UI/UX designer yesterday. I called Wendy to ask for a referral. Her response was classic Wendy: “You don't need a referral. I'll do it.”

No pitch. No negotiation. The most efficient, no-nonsense collaborator I've ever worked with.

Her background reads like a masterclass in scale: designing enterprise solutions at IBM, building platform ecosystems at NetEase Games, and creating digital patient tools at Sanofi and Takeda. She bridges the gap between corporate rigor and startup chaos.

What makes Wendy dangerous is her component-first thinking.

Over four years, she built design systems for us where every button and interaction pattern was modular and reusable. She challenged my instinct to show data for data's sake and taught me that restraint is a feature.

Every moment in Unrandom where you think “this just makes sense”: that's Wendy.

Today, she is a Co-founder and CPO at Brain Health Innovations, building AI-powered medical devices in Singapore. She advises Unrandom on product experience, bringing clinical-grade rigor to our analytics interfaces.

From gaming to pharma to brain health, the thread is the same: she makes complex systems usable for humans. That's exactly what Unrandom needed.
