What AveriStar does
AveriStar is a Charlotte, North Carolina-based private technology company that provided cloud-based unified communication solutions to service providers and large enterprises. The firm was founded in 2007 and operated with a small team of 11-50 employees. The core offering centered on cloud-based unified communication capabilities for clients, though specific named products, modules, or detailed service offerings are not documented in available sources, and no patents, certifications, awards, or pricing details are publicly disclosed. The company's short public description frames it as providing engineering and technical support services.
AveriStar's go-to-market appears to have followed a horizontal segmentation approach spanning two customer cohorts: service providers (treated as a primary vertical) and large enterprises (treated as a secondary size tier). Stated functional benefits were cloud-based unified communication capabilities and expanded U.S. market presence; no revenue mechanics, pricing model, customer logos, marketing channels, or distribution arrangements are disclosed. No management team, headcount details, subsidiaries, funding rounds, regulatory actions, or third-party integrations are documented.
On September 23, 2025, AveriStar was acquired by Clearspan in a private transaction. Per the disclosed acquisition rationale, the deal was strategic, intended to strengthen Clearspan's presence in the U.S. service provider market and expand its customer base for cloud-based unified communication solutions. Post-acquisition, AveriStar operates as a subsidiary of Clearspan and is no longer an independent operating entity. Limited additional information about AveriStar's operational history, ownership prior to acquisition, or financials is available from the provided sources.

AveriStar competitors and assessment
Company assessmentBroad incumbents
- Cisco (Webex): Cisco's Webex suite competes directly in cloud-based unified communications and has a large service-provider channel (BroadWorks, Webex Wholesale). Compares as a broad incumbent with overlapping cloud UC and carrier-distribution capabilities.
- Vonage (Ericsson): Vonage's UCaaS and communications APIs serve both enterprises and service providers, and is now part of Ericsson. Comparable as a cloud UC player with service-provider go-to-market.
- RingCentral: Public UCaaS leader offering cloud-based unified communications to enterprises and service providers. Comparable to AveriStar in product category (cloud UC) and target segments, but operates at vastly larger scale and as a broad incumbent across many verticals.
- Microsoft (Teams Phone): Microsoft Teams Phone is a dominant cloud UC platform with native Operator Connect for service-provider distribution. Comparable to AveriStar in target use case (cloud UC for enterprises and service providers) but at hyperscaler scale.
- Genesys: Cloud contact center and experience platform increasingly bundled with UC. Comparable as a cloud communications incumbent serving large enterprises and service-provider-led deployments.
- Zoom: Zoom's Zoom Phone and Zoom One bundles deliver cloud UC to enterprises, with growing service-provider distribution (Zoom Phone Provider Exchange). Comparable in cloud UC delivery model and enterprise target.
Emerging players
- Five9: Cloud contact-center-as-a-service provider adjacent to UC. Comparable as a cloud communications specialist targeting enterprise buyers, with partial overlap on customer base and delivery model.
Direct peers
- 8x8: Cloud UCaaS and CCaaS provider with a well-known service-provider/channel program (8x8 Voice for Teams, etc.). Directly comparable to AveriStar in delivering cloud unified communications through service-provider partners as well as direct enterprise sales.
- Mitel: Unified communications provider with deep service-provider/partner-channel roots and a transition from on-prem to cloud UC. Directly comparable to AveriStar in serving service providers with communications solutions, though Mitel is larger and more globally distributed.
- Sangoma: UC and PBX vendor serving service providers and SMB/mid-market enterprises through a partner channel, with both on-prem and cloud offerings. Comparable to AveriStar in the service-provider UC niche.
