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.
