What Acrobits does
Acrobits is a Prague-based provider of white-label UCaaS and VoIP softphone technology, operating as a wholly-owned subsidiary of Sweden-listed Sinch since 2016. Its core product, Cloud Softphone, is a no-code platform that enables telecom operators, managed service providers, and VoIP resellers to design, brand, and publish customized SIP-based softphone applications across iOS, Android, Windows, and macOS without in-house development. The platform's technical foundation includes a proprietary SIP Instance Server (SIPIS) for push notification delivery, native cross-platform code with 300+ customization options per OS, and pre-certified integrations with all major softswitches (BroadSoft, Metaswitch, Sangoma, NetSapiens, Asterisk, Cisco, Mitel). Acrobits also operates consumer-facing sub-brands (Acrobits Softphone and Groundwire) for direct SIP calling users, plus a developer SDK for embedding VoIP capabilities into third-party applications. Premium LinkUp features for group messaging and video conferencing, launched in 2025, extend the platform toward full white-label UCaaS.
The company monetizes primarily through subscription-based white-label deployments (approximately $4,000 one-time setup, $500/month base, plus per-active-user pricing), supplemented by SDK licensing, professional services including managed App Store/Play Store publishing, and one-time consumer app sales. Go-to-market is channel-led via 600+ telecom, MSP, and reseller partners, supplemented by direct enterprise sales emphasizing ROI calculators targeting CFOs, COOs, and IT managers. The company is GDPR compliant, HIPAA capable, and supports military-grade encryption (ZRTP, SRTP, TLS). Reported scale metrics include 140M-180M+ endpoints deployed, 500-700+ live branded apps, and operations spanning 78 countries (excluding CHN, IRN, PRK, RUS, SYR, BLR). Acrobits maintains a mid-sized engineering and sales organization (11-50 employees) under CTO Tomas Vyskocil, with dual legal entities in the Czech Republic (Acrobits, s.r.o.) and Switzerland (Alien Licensing gmbh).
