Consumer applications
Native and cross-platform clients built to be installed by ordinary people and then forgotten about. We ship for five platforms from one shared core, and we write the platform-specific parts by hand where it matters.

consumer software.
Privacy and networking tools for people who would rather not be the product. Small team, long horizons, no venture clock.

01 — What we do
Network infrastructure
The unglamorous half: provisioning, configuration delivery, telemetry, subscription state and the control plane that keeps them coherent. Operated on our own fleet rather than rented abstractions.
Licensing
Software distributed by subscription through established payment processors and the Apple and Google app stores. Conventional commerce, conventionally accounted for.
02 — Products
FlamingoVPN
Consumer VPN clientA consumer VPN application for macOS, Windows, iOS, Android and Chrome. Built on Xray-core with a shared TypeScript core and native tunnel engines per platform. Sold as a subscription, direct and through the app stores.
flamingovpn.comIn development
UnannouncedFurther consumer tools in the same domain. We announce products when they are ready to be used, not when they are ready to be described.
03 — Engineering
One codebase, five targets. Domain logic, protocol handling and state machines live in shared packages; the parts that touch the operating system are written against each platform directly rather than through a lowest common denominator.
Infrastructure is declarative and version-controlled. Deployments are reproducible, secrets are centralised, and the fleet is observable enough that we find out about problems before customers do.
