What we do

Four directions, one principle

We ship our own products across four directions — no client projects, no outsourcing.

SaaS services

Subscription platforms and cloud tools designed, built and operated by us end to end.

Bots

Automation and messaging bots for popular platforms, running reliably around the clock.

Games

Original games for desktop and mobile, taken from early prototype to release.

Mobile apps

Native and cross-platform applications for Android and iOS with a focus on polish.

About

Independent by design

Markelangelo Labs is an independent company. We fund, design, build and maintain our own products — which means every decision is made for the long term and for the people who use them.

Product-first

We only ship what we would use ourselves, and we keep supporting it after release.

Built in-house

Design, engineering and infrastructure stay inside the company — no outsourcing.

Quality & security

Accessibility, privacy and security are part of the product, not an afterthought.
