How We Work

We build what we'd use ourselves.

Every product here exists because someone on our team actually needed it. That's the filter — if we wouldn't use it daily, we don't ship it.

Start with a real problem

A parent tracking feeds at 3am. A car buyer watching COE prices. A student learning English through songs. Real people, real friction.

Build it properly

Native apps, not wrappers. Fast performance, clean UI, offline support. We'd rather take longer than ship something half-done.

Keep it independent

Self-funded, no ads, no data selling. We make money by making good products — not by exploiting users.

Building & Shipping

Meet the Founder

Tan Nguyen — Builder & Founder

With over a decade of experience building and shipping products used by millions, I founded The Everest Lab to create software that genuinely makes everyday life better — not for vanity metrics, but because real people need it.

Our team takes products from zero to launch across iOS, Android, and web. We obsess over craft, move fast, and stay independent — no VC funding, no compromises. Just great products, shipped with purpose.

Our Journey

Why 'Everest'?

It's not about the summit. It's about the climb — building something meaningful, one step at a time.

Read our full story

  • The Problem

    A new baby, sleepless nights, and no good app to track feeds and milestones. So we built one.

  • The First App

    Baby Joy launched on the App Store — built on weekends and late nights. 50K+ downloads and counting.

  • The Studio

    One app became two, then three. The Everest Lab was born — a home for practical, human-centered software.

  • The Mission

    Build useful apps for everyday life. No vanity metrics. No fluff. Just tools that make a real difference.
