What Hoiio does

Hoiio is a Singapore-headquartered Communication-Platform-as-a-Service (CPaaS) provider founded in 2007, operating as Hoiio Services Pte Ltd. The company has built a modular cloud communications platform anchored by Zentrex, its in-house proprietary Cloud PBX softphone, which supports simultaneous use across desktop, laptop, IP phones, and mobile SIM cards. The platform is delivered as a consolidated portal with integrated modules including Contact Center, MS Teams Phone, SIP Trunk, Super SIM (a first-of-its-kind enterprise-grade SIM in Singapore with MAS-compliant call recording and ISO 27001 certification), SMS Marketing, and E-Fax, with add-on capabilities such as call recording, auto-attendant, and CRM integrations.

Hoiio primarily serves enterprises and contact center operators, with secondary segments spanning individual business owners, working professionals, and regulated industries such as financial services. Operational scale is anchored in Singapore, with 5,000+ enterprise clients, 60,000+ phone lines deployed locally, and 300,000+ calls per day routed through the platform, backed by a 99.9% SLA. The company maintains offices in Singapore, Malaysia, Hong Kong, and Vietnam, and operates country-specific portals for Singapore, Malaysia, the United States, and Australia.

The business model combines subscription recurring revenue (Cloud PBX and app subscriptions on monthly or annual terms) with usage-based billing for telecommunications services (voice, SMS, phone numbers), prepaid credit balances, postpaid accounts requiring a security deposit, and an affiliate/referral commission stream via a partner program. Pricing is quote-based and not publicly disclosed, with both direct purchase through a self-serve web store and sales-led consultation available. Go-to-market mixes direct sales, self-serve e-commerce, and a formalized partner referral channel. No external funding rounds, acquisitions, or institutional investors are disclosed in the available data, indicating an organic, bootstrapped growth posture.
