NUWAVE makes the messy middle work.
Teams. Zoom. Webex. The easy part is choosing an app. NUWAVE handles the voice networks, numbers, and daily administration that make the choice usable.
Sharpen
The Indianapolis contact-center company that bet on the phone call - and is now teaching it to answer itself.
AI Rudder
AI Rudder is a Singapore-based voice AI company that automates high-volume customer phone calls and chats for banks, lenders, insurers, e-commerce and logistics firms. Its human-sounding voice agents handle payment reminders, verification, surveys, telemarketing and customer service across 15+ languages and regional accents, letting enterprises scale contact-center work without adding headcount. Backed by Sequoia, Tiger Global and Coatue, it serves 500+ enterprise clients concentrated in Southeast Asia and Latin America.
Flip
Flip is a New York-based vertical Voice AI company that answers customer service phone calls and resolves them end-to-end, without a live agent. Instead of routing callers through legacy IVR menus, Flip's AI assistant integrates deeply into a brand's backend systems to actually complete tasks - checking order status, processing returns, booking rides, and handling billing. The platform is purpose-built for specific industries (retail eCommerce, healthcare, and transportation) rather than offered as a one-size-fits-all bot. As of January 2026 Flip had automated more than 300 million calls for over 250 brands, automating up to 90% of inbound volume, and raised a $20M Series A.
