Checked against the stores on –
PiPi, my AI first mate, does twelve jobs. Captain, cartographer, cheerleader, and yes — the one in the hammock. Every hat is a context she gets pulled into. Tap one.













We wanted a name that was half math, half nonsense. Pi for the endless loop of software. Fl for the framework that lets one codebase fly across every platform.
Put them together and you get PiFl — which, read fast, sounds like a pirate with a lisp. Good. That's on-brand.
Our first mate is a parrot who codes — which is to say, she's the AI that rides shotgun while one human steers and signs off on everything. Twelve hats, one keel.
The endless loop. Mathematics, logic, and the comfort of infinity in a single symbol.
One codebase. iOS, Android, web, desktop. Wings included, batteries included.
Because "studio" sounds too precious and "corp" sounds too big. Labs ship scrappy.
We build calm apps
with a pirate spirit.
One codebase, two stores.
Zero krakens.

14 apps are already live. We're not done yet. Here's what's on deck right now.
