What Grifinum does

Grifinum s.r.o. is a Prague-headquartered, privately held B2B telecommunications provider operating globally with regional offices in Niš, Serbia and Beirut, Lebanon. Founded in 2018, the company reported a headcount of 11–50 employees and is led by a six-person management team whose members each carry 10–20+ years of telecom industry experience, with the Managing Director at roughly 20 years in international business and 15+ in telecommunications. Its product portfolio is organized around four lines: wholesale Voice Carrier Services (global voice termination with DTMF/fax support, premium CLI routes, and real-time anti-fraud monitoring), Messaging Services (SMS gateway supporting A2P, P2P, P2A, bulk SMS, and OTT channels including WhatsApp Business API, Viber Business Messages, and RCS), Voice Technology Services (ICT consulting covering Virtual IP-PBX, SS7/SIGTRAN implementations, SIP Trunking, and toll-free numbers), and the AI Conversational Platform (a REST-API-exposed omnichannel platform combining audio analysis — STT, TTS, voicebots, speaker detection/classification, audio annotation, keyword spotting — with text analysis — chatbots, summarization, machine translation, sentiment analysis, named entity detection, NL report generation, and email classification).

Grifinum serves a horizontal customer base spanning Tier1 carriers, global carriers, SMS aggregators, MVNOs, call centers, OTT services and calling apps, large enterprises and retail companies, and smaller local retailers, with a stated focus on hard-to-reach destinations and emerging regions in Europe, CIS, Middle East, Africa, Asia, and the Americas. The company runs a sales-led GTM with dedicated account management and a 24/7 Network Operations Center. Revenue is generated through usage-based voice termination fees, volume-based A2P/SMS message pricing, subscription/recurring AI platform services, and professional services for ICT consulting, with both pre-paid and post-paid billing options offered; pricing is not publicly disclosed. Strategic technology partnerships with Alarislabs (SMS hubbing) and Linxa (voice switching/billing) underpin the wholesale stack, with servers operated from the EEA.
