HiproCall

What HiproCall does

HiproCall GmbH is a Munich-based B2B software company specializing in professional voicemail and telephone announcement management solutions. Founded in 2003 (originally as HiPro|Call AG, converted to GmbH in 2009), the company's core offering is Enterprise Voicemail, a cloud-based platform that enables medium and large enterprises to deploy customized mailbox announcements integrated directly with telecom provider infrastructure. The platform supports calendar-based scheduling, real-time announcement switching, multi-language voice options, brand-consistent audio identity, and provider-independent deployment. In 2024, the company introduced AI-generated voice synthesis alongside its natural voice portfolio, enabling rapid, cost-efficient creation of phone announcements without requiring human voice talent.

HiproCall commercializes its portfolio through three distinct go-to-market motions. Enterprise Voicemail is distributed via direct enterprise sales with a 30-day free trial, backed by an extensive carrier partnership network spanning Vodafone, Deutsche Telekom, O2/Telefónica, T-Mobile, and PBX/telephony equipment dealers who receive up to 30% commission. Business Voicemail targets the SMB tier (1–50 users) through contact-based subscription sales with standardized personalization. Callstudio operates as a self-service e-commerce shop (callstudio.de) for individuals and micro-businesses purchasing one-off professional phone announcements with immediate or 5-day delivery. The company also operates WorkCompass, a separate browser-based workforce management tool with mobile time tracking, shift scheduling, vacation requests, and multilingual chat featuring automatic real-time translation in 100+ languages. Underlying technology includes four patents filed in 2008 for integrating audio branding into telecommunications infrastructure — claimed by the company as the world's first such patented solution, commercially launched in 2010 — plus certified integrations with major European PBX systems and telecom operators.

Disclosed enterprise customers include R+V Allgemeine Versicherung AG (6,500+ active mobile connections), PricewaterhouseCoopers, Barmer, ABB, EnBW, Adidas, BMW, Coca-Cola, and Audi. Headcount is stated at 11–50 employees and the company self-describes as an internationally operating German Mittelstand business with active customer relationships in Germany, Austria, Switzerland, and the United States. No external funding rounds are disclosed; the company appears bootstrapped and founder-managed, with Karl-Heinz Häuslein serving as Managing Director (Geschäftsführer) since founding in 2003.
