Your Role
As Junior Customer Success Manager for Activation in DACH, you make sure every new German-speaking customer goes from “just signed” to “fonio picks up our calls every day”. You own the first weeks of the customer journey: setting up their AI assistant, testing and fine-tuning it, and getting it live on their phone line.
You’ll spend most of your time in onboarding calls with customers and inside the fonio platform.



You learn how every feature works and figure out the best setup for each customer, whether that’s a dental practice in Munich, a law firm in Vienna or a car workshop in Zurich.

What to expect
• Run onboarding calls with new DACH customers and set up their AI assistant together with them

• Translate each customer’s business into a working setup: prompt, knowledge base, call transfers, notifications and integrations

• Test and fine-tune assistants until they’re ready to go live, so customers don’t get stuck in “almost done”

• Help customers connect their phone system and get call forwarding running

• Follow up with customers who signed but aren’t active yet, and get them over the line

• Become a power user of the platform: learn how each feature works and which setup fits which use case

• Bring patterns and friction points from onboardings back to Product and CS to improve templates, guides and the product

• Hand activated customers over to Custo
