The Quiet Infrastructure Behind 15 Billion Customer Connections
Every OTP, delivery alert and WhatsApp reply looks simple on a phone. CEQUENS has spent 15 years making the carrier routes, compliance rules and software behind those moments disappear.
Gupshup
It spent nearly two decades sending text messages nobody thought about. Now Gupshup wants those same pipes to carry AI agents that sell, support and close - one conversation at a time.
Bird
The Dutch company that rebuilt telecom's plumbing now carries a claimed 40% of the world's commercial messages - and spent two years trying to delete Twilio's margins with a 90% price cut. Bird's next bet is that the software placing those calls will be an AI agent, not a marketer.
