AI Voice & Calling Industry News Roundup — August 2026
A retailer puts an AI agent on its sales line, three voice AI startups raise fresh capital, and the infrastructure company underneath a lot of it all posts a record quarter. Here's what actually happened in AI voice and calling this stretch of 2026, sourced.
Enterprise adoption and venture funding both moved in the same direction this stretch: CarMax put a Sierra-built AI voice agent on its inbound sales line, three voice AI startups (Rime, Smallest.ai, Omilia) closed new funding rounds totaling over $100 million combined, and Twilio -- the messaging/voice infrastructure company much of this runs on -- reported record quarterly revenue with AI positioned as a growth driver going forward.
CarMax puts an AI voice agent on its inbound sales line
CarMax announced it's using an AI voice agent built by Sierra to handle inbound sales calls across its stores, live since May 2026. The agent answers common questions -- store hours, vehicle availability -- asks clarifying questions to understand what a caller actually needs, and routes the call to the right destination or a human associate faster and more consistently across call volumes, times of day, and time zones. CarMax says it's already seeing higher call resolution rates and fewer unresolved calls since deployment, and plans to expand the agent's role into appointment management for appraisals, vehicle browsing and test drives.
"We continually explore new and innovative ways to better serve customers and support our associates, and partnering with Sierra has been an important part of that," said Shamim Mohammad, CarMax's Chief Information Officer, in the company's announcement. CarMax operates more than 255 stores with roughly 28,000 associates.

Fresh funding: Rime, Smallest.ai and Omilia all raise
Rime, which builds voice AI models for enterprise customer calls, closed a $24 million Series A led by M13 Ventures, with Twilio Ventures, Corazon Capital and Unusual Ventures also participating. Rime says it now processes over 100 million calls a month for clients including Mayo Clinic, Dialpad, Upstart and Asurion, and is shifting toward speech-to-speech models to cut latency further. The company, founded in 2022, records its own conversational training data at a San Francisco studio rather than relying solely on licensed datasets.
Smallest.ai raised a $13 million Series A led by Seligman Ventures, with Sierra Ventures and 3one4 Capital also participating, bringing its total funding past $21 million. The company's voice model targets near-zero response lag in live customer support conversations, and hands off to a larger language model -- placing the caller on a brief hold, the way a human agent might -- when a query falls outside what it knows. Current customers include RingCentral and Truecaller.
Omilia, an enterprise conversational AI platform, secured a $67 million Series B to expand its "agentic self-learning" customer experience platform for large enterprises, with a stated focus on U.S. expansion.

Twilio posts record revenue as it leans into an "AI era" pitch
Twilio, whose infrastructure underlies a large share of the industry's voice, SMS and calling products, reported Q2 2026 revenue of $1.50 billion -- up 22% year-over-year (17% organic) -- and raised its full-year outlook. CEO Khozema Shipchandler framed the company's role as providing "the infrastructure for customer engagement in the AI era," positioning Twilio as the plumbing for both human agents and AI agents operating side by side, though the earnings release itself didn't break out how much of the quarter's growth came specifically from AI-driven usage versus Twilio's broader messaging and voice business.
What this means beyond the enterprise end of the market
Enterprise adoption is no longer experimental
CarMax putting an AI agent on a live sales line -- not a pilot, not a side channel -- signals that large, consumer-facing companies now treat AI call handling as production infrastructure, not a proof of concept.
Capital keeps flowing to voice specifically
Three separate raises in a few weeks, all focused on the voice layer rather than chat or general-purpose agents, suggests investors see voice as a distinct, still-unsolved technical problem worth funding on its own.
The infrastructure layer is being built out too
Twilio's positioning matters for smaller businesses indirectly -- as the underlying infrastructure matures and gets cheaper to build on, it tends to filter down into more affordable tools built on top of it, including flat-rate AI receptionist platforms.
