Customer.io's AI Agent reads the context already in your workspace, so one prompt is enough for it to build a journey, write the messages inside it and report back on how they performed. What comes out the other end is a proper onboarding sequence: email, SMS, push and in-app, triggered by what a new user actually did rather than by a date on a calendar. Product Hunt readers can apply to the Startup Program for up to 12 months of Customer.io free, subject to eligibility and approval.
