MIXVOIP Tech Stack

Cloud telephony and network services for SMEs and enterprises across Europe

Telecommunications Steinsel 51–200 employees Founded 2008 Privately Held

Mixvoip operates a cloud telephony platform (VoIP, cloud PBX, SIP trunking) built on open-source infrastructure (Asterisk, Proxmox, Ceph, Salt) and supported by Odoo for operations. The stack reveals a self-built, infrastructure-heavy business: in-house development across telecom and networking means engineering owns the core product. Current hiring is sparse and scattered across departments—sales, ops, marketing, legal, support—with no engineering roles posted in the last 30 days, despite active work on PBX backend and device provisioning. Pain points cluster around go-to-market (reseller adoption, differentiation, European scaling) and compliance, not technical capability.
