Staying close: How Sylvia Nguyen built something people truly needed

When MindPal first launched, it was just a weekend build. A simple app. A space to upload files and ask questions.

But what stuck — what kept it growing — wasn’t the tech. It was Sylvia’s decision to listen. Closely. Consistently. Even when it meant changing everything.

Today, MindPal brings in over $500k a year. Not from chasing trends. From staying curious about what her customers were actually trying to do.


From simple tool to quiet shift

Sylvia didn’t come from nowhere. She and her cofounder had spent over a year on a previous startup that never quite clicked. The problem? They weren’t talking to real customers.

They didn’t make that mistake twice.

With MindPal, they launched fast. A Product Hunt drop. 100 early users. Enough momentum to go full-time — and enough feedback to realize people wanted more than a “chat with your PDF” tool. They wanted real automation. Custom agents. Systems that matched their workflows, not generic templates.

So the product evolved. Slowly. Intentionally.

They added no-code logic. Multi-agent chains. Use cases grounded in real-life complexity — like medical summaries, coaching assessments, and onboarding systems.

Early on, Sylvia relied on tools like LangChain and the Vercel AI SDK. But it wasn’t long before they hit limits.

The platform needed more control. More flexibility. So they rebuilt parts from the ground up — shaving off friction, removing performance blockers, and making sure their product could grow without depending on unstable libraries.

It wasn’t the easy path. But it let them move faster, with more confidence.

Building in public — and with purpose

Much of MindPal’s growth came not from big budgets, but from clear intention.

A Facebook group (now 3,000 members strong). Educational YouTube videos. Free tools like their AI Agent Builder. And a simple affiliate system that rewarded people for spreading the word.

They used their own product internally, too — creating agents that ran parts of the business. Not to show off, but to test the product deeply. To find the edges. And to make sure it actually worked under pressure.

That’s what made MindPal sticky. Not just the features — but the care.

Sylvia isn’t chasing scale for scale’s sake.

Right now, the focus is on making the experience faster and more intuitive. Letting anyone, regardless of background, build their own AI systems without hours of onboarding. Without friction.

There’s a quiet confidence in the way she talks about the future. Less about world domination. More about helping people reclaim their time — so they can focus on the work that matters most.

Because AI, in her eyes, isn’t the thing. It’s the bridge.
