interface.ai sells AI agents purpose built for credit unions and community banks. Its BankGPT platform, launched in late 2025, spans Agentic Voice AI that answers member phone calls, Agentic Chat AI for web and mobile, and Agentic Employee AI that assists staff, all wired into core banking systems so the agents can actually do things: check balances, move money, manage cards, take loan payments. The agents authenticate members and complete transactions rather than just deflecting calls. In 2026 it added Smart Collections, a multi channel collections agent, and a bundled CCaaS offering through the Telarus partner program.
Srinivas Njay and Bruce Kim launched interface.ai in 2019, and Njay's origin story is genuinely charming: his father ran a credit union in India, and the company was built around institutions of that scale. It bootstrapped to more than 100 financial institution customers and tens of millions in annual recurring revenue before taking its first outside money in October 2024, a $30 million round led by Avataar Venture Partners, of which $20 million was equity and $10 million debt. The company says it now handles over 1.5 million conversations a day.
Pricing is entirely quote based. Nothing is published on the site, no tiers, no starting numbers, and deals are scoped to institution size, channels, and integrations. The company markets ROI cases rather than price points, which is common in this space but means you should benchmark against rivals like Posh AI, Glia, and Eltropy, and ask hard questions about one time implementation fees on top of the subscription.
Choose interface.ai if you run a credit union or community bank and want deep, prebuilt core integrations, it claims more than 40 Jack Henry implementations alone, plus voice as the flagship channel. It is a poor fit outside banking, and larger banks with in house AI teams or non financial businesses should look at horizontal platforms instead.

PolyAI answers the phone. While most of this directory started with chat and added voice later, PolyAI has been voice-first since three Cambridge machine-learning PhDs, Nikola Mrkšić, Pei-Hao Su, and Tsung-Hsien Wen, founded it in London in 2017 out of the university's Machine Intelligence Lab. Its agents are known for sounding genuinely human and for surviving the things that break lesser systems: interruptions, accents, background noise, and callers who change their mind mid-sentence. Restaurants, hotels, banks, and utilities use it to answer every call instantly, day and night, with customers like PG&E, UniCredit, Golden Nugget, and Fogo de Chao on the roster.
The platform matured into what the company calls an agentic dialog platform: Agent Studio for building and managing agents without code, a developer kit for deeper work, and Raven, a proprietary conversation model trained on more than a billion enterprise conversations. Compliance boxes (SOC 2, HIPAA, PCI) are ticked, which matters because taking payments and health information over the phone is exactly where voice AI earns its keep.
Investors have noticed the wedge. In December 2025 PolyAI raised an $86 million Series D at a valuation around $750 million, with NVIDIA's venture arm participating, bringing total funding past $200 million. Commercially it bills on usage, priced per minute of conversation, with rates scoped to your call volume rather than published on the site.
Choose PolyAI when the phone is your problem. If most of your support pain is hold music, missed calls, and staffing the night shift, a voice-native specialist will beat a chat-first platform's bolted-on telephony, and PolyAI is one of the most proven voice specialists in the market.
