## 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. 11,000+ customers. >€15M ARR. ~30% monthly growth. 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 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 Customer Success with a clean setup and clear notes
- Track your onboardings and activation results in HubSpot

Who We're Looking For

- 0–2 years of experience in a customer-facing role (onboarding, support, CS, sales, hospitality or customer service) or a strong graduate profile. Internships count.
- Native or C2 German, fluent English
- Basic technical skills and real curiosity about how things work. You enjoy clicking through a platform until you understand it, and you’re not scared of webhooks, APIs or phone settings.
- You like solving puzzles: “How do I build this for this customer?” excites you
- You explain things simply and stay patient with non-technical customers, by phone or video
- Structured: you can run several onboardings in parallel without dropping anything
- Hands-on and quick to learn. You take initiative and don’t wait to be told what to do.
- Willing to relocate to Vienna

## What We Offer

- €50,000–55,000
- You’ll learn AI and voice tech faster than anywhere else, with a real path into Customer Success, Solutions or Forward Deployment
- Lunch and dinner are on us. Every day.
- The fridge is always full: Red Bull, Mate, Cola, Almdudler and more
- Need a tool, course or book? It’s yours. No approval loops.
- Your setup, your choice: pick the gear you want to work with
- A product customers actually love: 4.5 stars on Trustpilot, Google and OMR. It mostly sells itself.
- Onsite in Vienna with a team that’s here to do the best work of their careers

Hiring Process

- 20 min intro call
- 30 min skill interview
- 15 min with interview with our CCO
- 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)
