Munich-based VoiceLine raises €10 million to scale its voice AI platform for enterprise frontline teams
VoiceLine, a Munich-based voice AI platform for enterprise frontline teams, today announced that it has closed a €10 million Series A funding round to scale its team and platform, as well as expand internationally.
The round was led by Alstin Capital and Peak, with participation from existing investors Scalehouse Capital, Venture Stars, and NAP.
Dr Nicolas Höflinger, CEO and co-founder of VoiceLine, said, “Field sales continues to be the backbone revenue driver for many industrial or services organisations. With VoiceLine, we are revolutionising the end-to-end reality of frontline work, from visit preparation and documentation to follow-ups, analytics, and insights – using voice as the most natural interface.
“We are proud to reach this milestone and grateful for the trust of our investors. This Series A enables us to further scale VoiceLine across Europe and make enterprise-grade Voice AI accessible to many more frontline organisations.”
Founded in 2020 by Dr Nicolas Höflinger and Sebastian Pinkas, VoiceLine is the voice AI platform for enterprise frontline teams in sales, service, and operations. It enables employees to capture information by voice, automate workflows, and generate actionable insights, with integration into existing enterprise systems.
According to VoiceLine, field sales and service teams spend most of their working day with customers, travelling between appointments, conducting visits or service calls, and coordinating follow-ups. The startup states that this leads to documentation, CRM updates, and handovers to back-office teams often getting postponed or not completed.
VoiceLine notes that because of delayed or incomplete reporting, missed follow-up tasks, valuable customer insights never reach enterprise systems. Consequently, managers have limited real-time visibility into field activities, and teams lose momentum between customer interactions.
VoiceLine claims to address this with a voice-first AI assistant built for the daily reality of field sales and mobile service teams. “After a customer interaction, employees simply speak to the assistant – by simply recording a voice memo on the go, or calling it via phone from the car. In the background, VoiceLine automates the entire frontline sales workflow in real time. Spoken inputs are automatically structured into visit reports, CRM entries, follow-up tasks, and visit preparations, and synchronised seamlessly with existing CRM, ERP, and other enterprise systems,” the company explained.
The German startup also mentioned that this creates access to structured, high-quality frontline data for the managers. With enhanced visibility into field activities, customer needs, and market signals, VoiceLine states that managers can react faster to changing market conditions, steer their organisation along proven success drivers, and enable more individualised, personalised customer experiences.
“Enterprise field sales is the engine of many B2B business models, yet administrative burdens are slowing it down. VoiceLine turns Voice AI into a productivity lever for mobile teams while simultaneously creating a new data foundation for strategic decision-making. This combination of measurable ROI and a scalable enterprise business model convinced us to lead the round,” said Andreas Schenk, Partner at Alstin Capital.
According to VoiceLine, unlike traditional enterprise software or CRM projects, it can be deployed within days. Its proprietary implementation engine enables enterprises to roll out fully customised Voice AI assistants for frontline teams with minimal IT involvement, while meeting enterprise-grade security and compliance requirements.
VoiceLine reports delivering measurable outcomes where most internal AI initiatives stall, achieving a pilot win rate of over 95% and deploying voice AI without the cost, complexity, or risks associated with in-house development.
Its mid-market and enterprise customers include DACHSER, ABB, Knauf, KSB, and Elis. According to the company, its customers report a reduction of up to 82% in administrative work for customer-facing teams, saving approximately five hours per sales representative per week.
Its customers also reported 400% more structured field data, and up to 96% of follow-up tasks forwarded within minutes, and frontline data available the same day.
In 2024, VoiceLine raised a €2.4 million Seed round led by Venture Stars and Scalehouse Capital. More recently, EU-Startups covered a €4.1 million funding round announced in December 2025 by Ghent-based Donna, which is developing an AI assistant focused on reducing administrative workload for field sales teams. Together, these rounds reflect continued investor interest in AI-driven tools designed to support frontline sales workflows.
The fresh capital will be used by the company to expand its team and further develop its AI platform. The company plans to more than double its headcount this year, with a focus on product development, sales, customer success, and partnerships. In parallel, VoiceLine aims to expand internationally and accelerate growth in additional frontline-heavy industries, including pharma, medtech, food & beverage, insurance, and financial services. It currently employs around 30 people and has achieved tenfold year-over-year growth.
