## Job description

Über fonio Wir sind in weniger als 12 Monaten von 1 Mio. auf 10 Mio. US Dollar ARR gewachsen und haben bereits jetzt über 10.000 Kunden. Fonio ist der europäische Marktführer für KI-Sprachagenten für SMBs. Nun expandieren wir weltweit und in neue Produktbereiche. Wir agieren schnell, glauben an ein hohes Maß an Ownership, leben direktes Feedback und verzichten auf Company-Politics und unnötige Meetings. Werde Teil einer der krassesten Wachstumsstories in Europa.

Deine Rolle Als GTM Engineer baust du die Systeme und Prozesse, mit denen wir unseren Hypergrowth auf ganz Europa skalieren. Du kombinierst moderne GTM-Tools, Daten und AI, um neue Leads zu identifizieren, anzureichern und in skalierbare Outbound-Maschinen zu verwandeln.

Das erwartet dich

- Aufbau skalierbarer Lead-Generation-Workflows mit Tools wie Clay, Apollo, HubSpot, Instantly, Smartlead oder ähnlichen Plattformen
- Recherche, Anreicherung und Qualifizierung von Leads über unterschiedliche Datenquellen und APIs
- Entwicklung und Optimierung von Outbound-Kampagnen gemeinsam mit dem Founding Team – von Targeting über Messaging bis Deliverability
- Automatisierung von Sales- & Marketing-Prozessen mit AI und modernen SaaS-Tools
- Analyse von Funnel-, Conversion- und Kampagnendaten zur kontinuierlichen Optimierung
- Direkte Zusammenarbeit mit Product & Engineering, um GTM-Learnings zurück ins Produkt einfließen zu lassen

Wen wir suchen

- Extremes Growth Mindset: du willst Systeme bauen, die 10x mehr Leads bringen
- Erfahrung mit modernen GTM- & Lead-Generation-Tools (z.B. Clay, Apollo, HubSpot, Instantly, Smartlead, PhantomBuster)
- Starkes Verständnis für Outbound, Lead Enrichment und datengetriebenes Wachstum – du weißt, was ICP, Intent-Signale und Deliverability bedeutet
- Technisches Verständnis und idealerweise erste Erfahrung mit APIs, Automatisierungen oder Skripting – du musst kein Senior Engineer sein, aber wenn du eine API-Doc liest, panikst du nicht
- Pragmatismus: Du hältst Dinge einfach, startest lean und shipst, sobald du etwas lernen kannst
- Deutsch als Muttersprache, um mit unserem DACH-Kundensegment direkt zu arbeiten und sehr gutes Englisch

Was wir bieten

- Kompetitives Gehalt: €65.000-€95.000 pro Jahr
- 100% Remote: Falls du aber Lust auf Office hast, haben wir eines der coolsten Offices im 7. Bezirk in Wien (Lunch & Dinner included)
- 100% Focus Time (keine regulären Meetings)
- Unlimited Budget, wenn der ROI stimmt
- Extremer Speed (wir shippen fast täglich)
- Tausende begeisterter Kunden, die das Produkt gemeinsam mit uns entwickeln.

Bewerbungsprozess

- 15 min Kennenlernen
- 30 min Deep Dive mit CTO & Co-Founder Matthias
- 90 min Technical Interview mit GTM Case
- 15 min Culture Fit mit einem der Gründer

## 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)
