Brex, a financials organization in the United States, uses Sonic from Cartesia to support engineering for developers.
Developers at Brex review software delivery in Sonic rather than in personal files.
“From the United States, financials teams still had to serve customers and internal partners who expected a straight answer.”
“Cartesia develops real-time voice AI, including Sonic text-to-speech and Ink speech-to-text, for conversational products and agents.”

Story
Brex grew software delivery faster than the local tools around it. From the United States, financials teams still had to serve customers and internal partners who expected a straight answer. Developers were the ones stitching the picture together by hand.
Rolling out Sonic put engineering on Cartesia. Cartesia develops real-time voice AI, including Sonic text-to-speech and Ink speech-to-text, for conversational products and agents. Brex keeps the product in the path where work already happens, so developers do not context-switch into a graveyard system used only for audits.
The visible result is steadier engineering. Software delivery is easier to inspect, and adjacent groups can join developers without a guided tour of someone's desktop.
