What Host SBC does

Host SBC, LLC is a privately held cloud communications provider headquartered in Coral Gables, Florida, founded in 2011. The company operates the RTC ONE platform, a cloud-native Real-Time Communications solution that centralizes SIP trunking, phone number management, Microsoft Teams voice integration, voice traffic routing, and customer billing into a single multi-tenant environment. The platform is designed for both internal business communications and white-label resale by service providers, with DID availability in 110+ countries supported by certified carrier partnerships and built-in STIR/SHAKEN call authentication. The technology stack is fully cloud-based with no hardware dependency, targeting businesses transitioning from legacy phone systems to scalable, internet-delivered voice services.

The company's revenue model combines tiered SaaS subscriptions (Starter $250/month, Advanced $649/month, Enterprise $878+/month), usage-based voice billing (e.g., $0.0057/min for US inbound SIP), per-seat Teams integration pricing ($3-$4.50/user/month), and phone number services. The go-to-market motion is hybrid: a self-service demo and trial environment for product-led acquisition, paired with direct enterprise sales via WhatsApp, phone, and email for larger deals. The company maintains Network Operations Centers in Colombia (bilingual English-Spanish support for the Americas) and India (bilingual English-Hindi support for EMEA), enabling 24/7 follow-the-sun operations. HostSBC is led by Co-Founder and Managing Director Oswaldo Arratia, with Juan M. Gomez on the Board of Directors, and operates as a bootstrapped LLC with no disclosed external funding.

Direct peers

• Plivo: Plivo offers cloud voice and messaging APIs, SIP trunking, and phone numbers globally with usage-based pricing and reseller-friendly APIs — a direct competitor to HostSBC for SMB and developer-driven voice customers.
• Telnyx: Telnyx is a direct competitor offering cloud-native SIP trunking, global DIDs, and programmable voice/SMS with usage-based pricing and a self-service portal — closely mirroring HostSBC's RTC ONE model and reseller-friendly positioning.
• Bandwidth: Bandwidth is a direct peer supplying SIP trunking, global phone numbers, messaging, and a white-label/reseller-friendly voice platform — directly comparable to HostSBC's RTC ONE in product scope and target customer (service providers and enterprises).
• IntelePeer: IntelePeer provides cloud communications including SIP trunking, voice, and Teams integration for enterprises and service providers — closely comparable to HostSBC in target customer (mid-market/enterprise), product scope, and white-label channel motion.

Emerging players

• NetSapiens: NetSapiens provides a white-label UCaaS platform built specifically for service providers to deliver hosted PBX and SIP trunking under their own brand — a closely comparable architecture to HostSBC's reseller-oriented RTC ONE platform.
• Alianza: Alianza offers a cloud communications platform for service providers, replacing legacy TDM/hosted PBX with a fully cloud-native, white-labelable voice stack — directly analogous to HostSBC's RTC ONE for the service-provider channel.

Broad incumbents

• 8x8: 8x8 is a publicly traded UCaaS/CCaaS incumbent providing cloud PBX, SIP trunking, and Teams integration — overlapping with HostSBC on hosted telephony and Teams voice enablement, but as part of a much broader enterprise suite.
• Vonage (Ericsson): Vonage, now part of Ericsson, offers UCaaS, SIP trunking, and APIs for voice/SMS, serving both enterprises and service providers — competing with HostSBC's cloud communications platform while also offering a much larger product suite.
• Twilio: Twilio is the largest CPaaS incumbent providing SIP trunking (Elastic SIP Trunks), programmable voice/SMS, and global numbers via APIs. It overlaps with HostSBC's SIP trunking, DID, and messaging offerings but at materially larger scale and a developer-first orientation.
• Sinch: Sinch offers cloud communications including SIP trunking, voice, and messaging to enterprises and service providers globally, with broader geographic reach and acquired assets (MessageBird, Inteliquent) that compete with HostSBC's voice and DID portfolio.
