Your Role

As Customer Success Manager for the DACH market, you are the primary point of contact for your customer cohort (of SMBs) once they've signed. You own their success, satisfaction, and retention end to end.

You actively build relationships, identify value drivers, and ensure every customer gets the most out of fonio. You'll spend most of your time in calls and meetings with customers.

What to expect

• Own a portfolio of DACH SMB customers across their full lifecycle

• Build relationships, surface value, and find new use cases for AI agents to keep customers engaged

• Run check-ins and proactive calls based on usage signals (low engagement, expansion opportunities, setup friction)

• Work with a ready-made pipeline and clear playbooks, with room to test your own initiatives

• Maximize the value generated from each customer in your portfolio

• Support customers in setting up their AI assistant; coordinate with developers for complex setups

• Spot churn risks early and act on them

• Manage your activity autonomously in HubSpot

Who We're Looking For

• 2–5 years in Customer Success, Account Management, or a client-facing SaaS/B2B role

• Native or C2 German, strong English

• Structured, autonomous, results-driven

• You build trust easily with customers, by phone or video

• You take initiative, test, iterate, and don't wait to be told what to do

• Comfortable with CRM (ideally HubSpot) and data-driven workflows

• Affinity for tech/AI is a plus

• Willing to relocate to Vienna

What We Offer

• €60,000–80,000 OTE

• Equity: you help build it, you should own a piece of it

• Equipment of your choice

• A product that sells itself and that customers love (4.5 stars on Trustpilot, Google, and OMR)

• Regular team offsites

• Office in Vienna, onsite, in an ambitious team that wants to do the most exciting work of their careers
