Founder-led software studio · Amsterdam

Technology,
on your terms.

Mendox makes privacy-focused software. Our first product, Bubbly, gives the apps and sites that pull you in one shared time budget. We also build SaaS for clients.

Bubbly is in testing on Android, Chrome and Firefox

Most tech is built to
pull your attention apart.

We build the kind that
puts it back together.

Mendox, from mend.

01Our product

One budget for the apps that take your time.

Bubbly groups the apps and sites that pull you in and gives them one shared allowance. When it runs out, they take a nap, on your phone and in your browser.

Bubbly

Digital wellbeing · Android, Chrome & Firefox
In testing

Put the apps that eat your evenings in a bubble. They share one stash of time, with limits for a sitting, a day or a week, and a break when it runs out.

  • One budget, shared by your phone and your browsers
  • Can count just the part that pulls you in, like YouTube Shorts
  • Records which app or site and for how long, never what’s on screen
  • Usage and settings are encrypted on your device before they sync to servers in the EU

Two sides.

Our own products, and software for our clients.

One standard.

Private by default. Calm by design. Built to be put down.

Every angle, considered.

Short loops and real polish, from the first sketch to production.

02Client work

SaaS, built with care.

Mendox also builds software for clients: web apps and SaaS products, with privacy designed in from the start instead of bolted on before launch.

01

SaaS, from idea to launch

Scoping, UX, the web app itself, accounts, payments and a production setup you can grow on. From first sketch to first invoice, without hand-offs.

  • Product & UX
  • Web app
  • Auth & billing
02

Web, mobile and browser

TypeScript and React on the web, React Native and Kotlin on phones, and browser extensions when the job lives in a tab.

  • React
  • React Native
  • Kotlin
  • Extensions
03

AI features people trust

Useful LLM features with clear data flows: what goes where, what is kept, and what never leaves the device.

  • LLMs
  • Agents
  • Guardrails
04

Privacy and security by design

Collect only what a feature needs, encrypt end to end where it matters, host in the EU where that’s an option, and make deletion actually delete.

  • Data minimisation
  • E2E encryption
  • EU hosting

How a project runs

  1. 01

    Talk

    A free intro call about what you’re building, who it’s for and what success looks like.

  2. 02

    Shape

    A clear scope, a clickable prototype and a fixed estimate before anything is built.

  3. 03

    Build

    Short cycles with a working demo every week. You see progress, not status reports.

  4. 04

    Launch

    Production, monitoring and a handover. The code is yours; we stay on if you want us to.

03Studio

Founder-led, on purpose.

Mendox is a software studio in Amsterdam. We build our own products, starting with Bubbly, and take on selected client projects, so you work directly with the person building your software.

Private by default

Collect what a feature needs, explain why, and make any extra sharing a choice. If a feature doesn’t need your data, it never sees it.

Built for intention

No dark patterns, no infinite feeds, no guilt trips. Start from a concrete problem, help people decide, then get out of the way.

Made with care

Reliability, accessibility and the small interaction details are part of the work from the first day, not polish for later.
