Airship
San Francisco
In our mobile-first world, customers expect a unified, seamless experience wherever they interact with brands. But most often, those experiences are disconnected. Airship has everything you need to get mobile-first customer experience right — on the web, in the app and everywhere in between. Since the dawn of mobile apps, Airship innovations have become industry standards. We delivered the industry’s first push notification and first in-app message. Then we powered the first mobile wallet boarding pass, now the digital norm for travelers. We enabled the first commercial use of Live Activities on the day it was launched by Apple. Most recently, we launched the world’s first no-code native Experience Editor for app and web, enabling marketers and product managers to engage with customers wherever they are and get work done in minutes instead of months without ongoing developer support. Today, the Airship Experience Platform provides an end-to-end solution for unifying experiences across channels and capturing value across the entire customer lifecycle. It starts with Airship’s market-leading app store optimization (ASO) solutions that promote app discovery and downloads. Then our AI-powered journey orchestration, content creation and experimentation solutions kick in — all no-code and highly flexible. Customer-facing teams can quickly design, deploy and iterate cohesive in-session experiences on the web and in the app. The result? Deeper customer engagement, better conversion. When it comes to helping brands get customer experience right in a mobile-first world, no one knows more, does more or cares more than Airship.
