We make apps people keep.

Twenty apps. Twenty million people. Since 2011.

Fax · Mobile, desktop and web

mFax

Nobody wanted the fax category, so we took it. One account sends and receives on every screen a clinic or a law office uses, and keeps the delivery record they have to produce.

Open source

We build our own tools, too.

We are engineers first. Next to the products we write the tools we work with: our own AI agent, and two Mac apps for the hours we spend in Claude Code. All three are public on GitHub.

A GoGogot run from go-go-got.com: one request, six iterations of tool calls with their timings, done in 3.56 seconds

GoGogot

Agent · Go

A self-hosted AI agent: a shell, files, web tools, memory and a scheduler, answering in Telegram.

Octa Lab

Everything behind our apps, we do ourselves.

We build our own products, publish them under our own name and run everything behind them, down to the tools we work with. One team, in Dubai and Hong Kong.

Partnership

You built the app. We run everything else.

Co-publishing for products that have traction and no operating team behind them. Terms are set per deal, and you talk to the people who will do the work.

You bring

  • A live app with retention you can show
  • The product judgement that got it there
  • Room to move on pricing

We run

  • Store, reviews and ASO
  • Backend, telephony and billing
  • Paid acquisition and attribution
  • Contracts and payouts in two jurisdictions
