VoiceLine raises €10M to expand enterprise voice AI for frontline teams

Munich-based VoiceLine, a voice AI platform for enterprise frontline teams, has closed a €10 million Series A funding round. The round was led by Alstin Capital and Peak, with participation from existing investors Scalehouse Capital, Venture Stars, and NAP.

Field sales and service teams spend much of their time with customers, travelling between appointments, conducting visits, and coordinating follow-ups. As a result, documentation, CRM updates, and back-office handovers are often delayed or deprioritised, leaving teams to spend several hours each week on administrative work instead of customer-facing activities. This can lead to incomplete reports, missed follow-ups, and customer insights that never reach enterprise systems, limiting real-time visibility for managers and disrupting continuity between interactions.

VoiceLine addresses this challenge with a voice-first AI assistant designed for the daily workflows of field sales and mobile service teams. After a customer interaction, employees can record a voice memo on the go or call the assistant by phone. The platform then automates key frontline workflows in real time, converting spoken inputs into structured visit reports, CRM entries, follow-up tasks, and visit preparations, which are synchronised with existing CRM, ERP, and other enterprise systems.

For managers, this creates access to structured frontline data that was previously difficult to capture, improving visibility into field activities, customer needs, and market signals, and enabling faster, more informed decision-making.

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,

said Nicolas Höflinger, CEO and co-founder of VoiceLine.

Unlike traditional CRM projects, VoiceLine can be deployed within days, enabling customised voice AI rollouts with minimal IT involvement while meeting enterprise security requirements.

VoiceLine is already in use among mid-market and enterprise customers, including DACHSER, ABB, Knauf, KSB, and Elis, supporting deployments across multiple countries and thousands of frontline users.

The new funding will be used to expand VoiceLine’s team and further develop its AI platform. The company plans to significantly increase headcount this year, with a focus on product development, sales, customer success, and partnerships. In parallel, VoiceLine intends to extend its platform to additional frontline use cases and grow its international presence.
