Fonio is Europe’s market leader for AI phone agents for SMBs. Now we’re expanding globally and into new products. We move fast, take ownership, give direct feedback, and avoid politics and unnecessary meetings. Join one of Europe’s fastest-growing companies. ## Your role You own how fonio feels on the web. Our website is our most important storefront — and right now it's not where it needs to be. You don't build one nice page, you build a system: a design system and landing page templates that roll out into localized pages across 9+ markets. Continuous optimization, not a one-off redesign. You design and ship - you own the build end-to-end, not a handoff to engineering. We're building an AI operating system for SMBs - people should feel that on the website. What to expect - You own the design and continuous optimization of our website and landing pages - You build a scalable design system with reusable components - You develop landing page templates that localize across all markets (DACH, FR, IT, ES, UK, PL, US, and more) - You design and ship live yourself - full ownership from concept to published page - You think in user journey, conversion, and responsive design - You work closely with the Creative Director on brand direction Who we're looking for - Several years of experience as a UI/UX or web designer focused on converting websites (portfolio required) - You think in systems and components, not individual pages - You build and ship yourself - Experience with design systems and localization across multiple markets - You understand conversion and think in journeys - German at native level + good English ## What we offer - Competitive salary: €65,000–€90,000 - Equity - you're building this, so you should own a piece of it. - Food & drinks - lunch and dinner are on us at the Vienna office (plus all the drinks you want, and yes, we have protein bars and vitamins too). - Relocation bonus (if you still need to move to Vienna) - Equipment of your choice - whatever makes you happy. - Regular team offsites. Hiring process - 15 min intro call - 30 min skill interview - 20 min culture fit with the 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).
