## Job description

## About fonio

We build AI voice agents for small and medium-sized businesses so they never miss a call and can focus on the work they actually love. Our AI handles every call automatically. But voice is just the beginning. Our vision: to build the world's first fully automated CRM. 8.000+ customers. >€5M ARR. ~30% monthly growth. Target until EOY: €30M. We live ownership. You're responsible for your projects and tasks end-to-end. No politics, few meetings, direct feedback. At fonio you’ll build alongside the smartest and most ambitious people around. Join us now to be part of one of Europe's most exciting growth stories!

## Your Role

As Technical 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 and implementing or improving their setups.

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
- Support customers in setting up their AI assistant; implement workflows for medium complex cases and coordinate with developers for advanced setups
- 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
- 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, Forward Deployment Engineer or a technical client-facing SaaS/B2B role
- Ideally a strong technical understanding — comfortable understanding API documentation and error logs to troubleshoot customer setup issues independently
- Experience with tools like n8n, [make.com](http://make.com), codex or similar
- An affinity for tech / AI products is a real plus
- 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
- Willing to relocate to Vienna for 1–2 months initially

## 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

Hiring Process

- 15 min intro call
- 30 min skill interview
- 20 min culture call with our Founders

## About fonio

## Company Overview
- **One-liner**: fonio is a European AI platform that provides AI phone assistants and omnichannel customer communication solutions for small and medium-sized businesses.
- **Entity Type**: Private (Seed stage)
- **Headquarters**: Vienna, Austria
- **Founded**: 2024
- **Founders**: Daniel Keinrath (CEO) and Matthias Gruber (CTO)

## Core Business
- **Primary industry**: AI-powered customer communication / Telecommunications
- **Target customers**: B2B, primarily small and medium-sized businesses (SMBs) with high volumes of customer calls
- **Mission or purpose statement**: To ensure no lead, customer, or opportunity is missed by providing 24/7 AI-powered communication across phone, WhatsApp, email, and chat.

## Products & Services
- **AI Phone Assistant**: An AI agent that handles inbound and outbound calls, capable of scheduling appointments, answering inquiries, processing orders, and transcribing conversations. It features speech recognition for difficult dialects, turn-detection for natural conversation flow, and real-time emotion recognition. It can be set up in under 10 minutes with no coding required.
- **Omnichannel Platform**: Expanding beyond voice to include WhatsApp (already live), with email and chatbot support to follow. The platform integrates with CRMs, calendar tools, and databases via native integrations and APIs.
- **Proprietary Calendar**: An AI-native calendar tool that is already live as part of the platform.
- **Proprietary CRM**: A CRM purpose-built for AI-driven customer interactions, expected to launch by the end of Q3 2026.

## Market Standing
- **Valuation/Market Cap**: $140 million valuation (as of June 2026, per seed round)
- **Key Metric**: Total funding of over $20 million, including a $17 million seed round led by 20VC (June 2026) and a €3 million angel round (December 2025).
- **Notable Investors/Partners**: 20VC (lead), with participation from founders and executives of Synthesia, HubSpot, and Revolut. Previous angel investors include early backers of Facebook and Airbnb.
- **Growth Signals**: 
    - Over 7,000 customers across nine markets (Austria, Germany, Switzerland, France, Italy, Poland, Brazil, UK, USA)
    - Automates over 2 million calls per month
    - Growing at roughly 40% month-over-month
    - Acquired competitor fluently in September 2025
    - Added $1 million in ARR in April 2026 alone, targeting a 5x increase by year-end
    - Opening offices in New York, Munich, Milan, Paris, London, Warsaw, and Barcelona

## Competitive Advantages
- **Proprietary European Infrastructure**: Develops its own orchestration layer and models (speech recognition, turn-detection, emotion recognition), ensuring all data remains in the EU on servers in Nuremberg, Germany. This differentiates them from competitors who white-label US services.
- **High End-to-End Resolution Rate**: In roughly 90% of cases, the AI agent conducts a fully human-like conversation and resolves the inquiry without needing to route it to a human.
- **Builder-Heavy Team**: Over half the team are former founders, operations leaders, or people who have scaled products at companies like Canva.

## Strategic Focus
- **Omnichannel Expansion**: Moving beyond voice to become a full omnichannel platform (WhatsApp, email, chat).
- **International Expansion**: Establishing physical offices in key markets (New York, Munich, Milan, Paris, London, Warsaw, Barcelona) after recent launches in the UK and US.
- **Building an AI-Native Tool Ecosystem**: Developing a proprietary calendar and CRM to create a complete, integrated platform for customer communication.

## Why Work Here
- **Rapid Growth & Impact**: The company is in a phase of hypergrowth (40% MoM), and employees are "still early enough that your work will genuinely shape the culture, the product, and the company." [fonio.ai/en/careers](https://www.fonio.ai/en/careers)
- **Culture**: Described as fast, committed, and in-office by default. The team emphasizes moving fast and having fun. Most roles are Vienna-based, with the expectation of being in the office most days.
- **Remote Options**: Engineering roles are fully remote (within ±3 hours of CET). For other roles, there is a temporary relocation to Vienna for onboarding (1-3 months), followed by relocation to the target market.
- **Relocation Support**: The company sponsors travel and accommodation in Vienna for the onboarding period and offers full relocation support for moving to target markets.
- **Team Size**: Around 40-50 people, with plans to double by the end of the year.
- **Hiring Process**: A 3-4 step process: 15-minute intro call, 30-45 minute skills interview (sometimes with a case study), potentially a deeper skills or leadership interview, and a final 20-minute culture call with both founders. [fonio.ai/en/careers](https://www.fonio.ai/en/careers)
