Our Product · Formerly PebbleFlow
Built by Six Cailloux, Caiioo.ai (formerly PebbleFlow.ai) is our flagship product bringing AI-powered agentic workflows to individuals and teams. We needed a more unique name — drawn from the French caillou — yet the modesty and solidity of the pebble and the desire for workflow permeate the application still.
About
Six Cailloux is a software development company based in Portland, Oregon. We specialize in building software products and providing AI implementation consulting services.
We are the creators of Caiioo.ai (formerly PebbleFlow.ai) and other software tools designed to help teams work more effectively. While we needed a more unique name for our flagship platform, the modesty and solidity of the pebble and the desire for workflow permeate the application still. Our approach is practical — we ship software that works and help our clients do the same.
The name “Six Cailloux” means “six pebbles” in French — stepping stones across the river, providing a path forward.
