What TENIOS does

TENIOS is a German cloud communications provider founded in 2001 and headquartered in Cologne. The company delivers programmable Voice, SMS, and Voicebot APIs alongside cloud telephony (Cloud-PBX, SIP trunking, IVR, ACD), messaging (SMS, RCS, WhatsApp Business API), and phone number services covering 5,200 German local networks and 100+ countries internationally. Its reported customer base exceeds 2,000 enterprises across healthcare, call centers, marketing, e-commerce, betting/gaming, and city marketing, with documented deployments for Foxford (1M+ students), Weegree, Betfan, LPP, and Bluepartner. The business operates under Bundesnetzagentur regulatory oversight and is reportedly part of the broader Apifonica Group, with Sascha Korten appointed Managing Director in June 2026.

TENIOS's technical core is a proprietary Telekommunikationsplattform that underpins its AI Voice Agents, which autonomously conduct phone conversations in 150+ languages with sub-second response times, active interruption handling, and proprietary emotion recognition. Speech processing relies on Google Cloud Speech-to-Text, Microsoft Azure, and ElevenLabs for ASR and TTS, while conversational understanding leverages OpenAI's ChatGPT layered with TENIOS's own call-flow and routing logic. The platform integrates with 2,000+ systems including Salesforce, HubSpot, Zoho, Pipedrive, and MedChart, and is certified to DIN EN ISO/IEC 27001, GDPR-compliant, and hosted in geo-redundant German data centers.

Commercially, TENIOS runs an API-first go-to-market with a self-service developer portal and 30-day free trial, complemented by direct sales consultation for enterprise voicebot engagements. Revenue is a hybrid of usage-based APIs (SMS at €0.07 in Germany, €0.06 in Austria; per-minute telephony), recurring subscriptions (SIP channels at €1/channel/month, WhatsApp Business API at €50/month), and bespoke voicebot solutions priced on type, features, and contact volume (3-5 week implementation for custom bots). Demand generation relies on a blog, e-books, webinars, paid search, and case studies, while partnerships with Google, Microsoft, OpenAI, and ElevenLabs anchor the underlying AI stack.
