C4

C4 is a flexible, cloud-based Customer Experience (CX) solution designed for businesses that want powerful features without the complexity of legacy platforms. With C4, you get everything you need to run a high-performing contact center—voice, digital channels, intelligent routing, reporting, and integrations—delivered through a platform that’s easy to customize and fast to deploy. Unlike traditional CCaaS platforms, C4 is agile by design. That means quick deployments, responsive support, and the ability to request and implement custom API functionality without the wait. Users have more self-service control over configuration, workflows, and reporting—reducing dependency on IT or vendor support. Whether you’re a small team scaling up or a large enterprise looking for a more nimble alternative, C4 offers enterprise-grade capabilities with startup-level flexibility.

CallsAround

CallsAround is a 24/7 AI answering service with emergency dispatch for home-service businesses (restoration, HVAC, plumbing, electrical, cleaning). It answers every call with a natural-sounding, configurable AI receptionist, qualifies leads, answers FAQs, and books appointments against your live Google Calendar. When a call is a real emergency, CallsAround doesn't take a message - it dispatches. It rings your on-call chain in order, detects answering machines (voicemail never counts as an answer), sends SMS alerts at every escalation hop, and warm-transfers with context so your tech knows who's calling and why before they pick up. Carrier-level dead-man failover tests the line every few minutes and routes around upstream outages, so callers never reach dead air. Every call is on the record: recordings, transcripts, and a journaled escalation trail. Setup is instant and self-serve - live the same afternoon, no demo call, no onboarding project - with flat month-to-month pricing and no contracts.
