Parloa

Enterprise agentic AI for contact centres across phone, chat and messaging

About Parloa

Parloa builds AI voice agents for contact centres, automating dialogue across phone, chat, voice assistants and messenger apps at the level of a human call centre agent. It went from a $1B valuation in May 2025 to $3B in January 2026 on the back of a $350M Series D, passing $50M ARR with customers including Microsoft, Accenture, KPMG and Booking.com. Sistava operates at the other end of the market: self-serve AI employees for founders and small teams, where voice is one of many channels.

What is Parloa?

Parloa automates contact centre conversations. Not a chatbot with a phone number attached: agents designed to handle the messy reality of live phone support, including interruptions, accents, background noise and the moment where the call has to go to a human without the customer repeating themselves. It launched in 2018 out of Berlin and grew quietly before the agentic wave arrived, which shows in the product maturity. Customers include Microsoft, Accenture, KPMG and Booking.com, and it passed $50M ARR. The funding trajectory is one of the steepest in European enterprise software: $120M Series C in May 2025 at a $1B valuation, then just seven months later a $350M Series D that tripled the valuation to $3B, taking total funding past $560M.

Contact centre scale versus small business

Parloa is built for organisations where inbound call volume is a staffing line in a budget. At that scale, a few percentage points of containment is worth millions, and an enterprise implementation pays for itself. None of that logic applies to a company taking thirty calls a week. The implementation cost alone exceeds the entire problem, and the product is shaped around integrations with contact centre platforms most small businesses have never bought. Sistava treats voice as a capability an employee has, alongside email, chat and the browser. A support employee that can answer the phone when it rings is a different thing from a platform that automates a call centre, and small businesses need the first one.

Evaluating enterprise voice vendors

If you are genuinely in Parloa territory, the questions that matter are containment rate on your actual call mix, how gracefully it hands off to a human, what happens on the edge cases, and how long implementation really takes. Ask specifically about the handoff. Most of the customer pain in automated phone support is not the bot failing, it is the bot failing and then making you start over with a person. And ask about the languages and accents in your customer base, tested on real recordings rather than a demo script. That is where voice platforms separate.
