Comparing Cresta and Parloa? Both are Contact Center & CCaaS and Voice & Phone AI tools in the directory, which is why buyers put them on the same shortlist. Below is a side-by-side look at how they price, what they integrate with, and when each is the better fit, so you can pick on the facts rather than either vendor's own sales page.

Cresta started from a simple observation: in every contact center, a handful of agents dramatically outperform the rest, and everything they do differently is sitting in the call recordings. Founded in 2017 by Zayd Enam, Tim Shi, and Sebastian Thrun, the Stanford professor behind Google X and Udacity, Cresta mines those conversations to learn what the best performers do, then coaches every agent in real time: suggested responses, knowledge, and guidance appearing on screen during live calls and chats.
That real-time layer is still the heart of the product, but the platform now spans the full loop. Conversation intelligence gives leaders visibility into every interaction, automated quality management replaces sampled QA scorecards, a training simulator lets agents rehearse against AI customers, and autonomous virtual agents take the high-volume calls that never needed a human. It plugs into the major contact-center stacks, including Five9, Genesys, Amazon Connect, NICE, and Avaya, so it layers onto what you run rather than replacing it.
Cresta sells to serious operations: United Airlines, Alaska Airlines, Cox Communications, Marriott, and Brinks Home are named customers, and investors including Andreessen Horowitz, Sequoia, and Greylock have backed it to the tune of roughly $276 million, most recently a $125 million Series D in late 2024 that valued the company around $1.6 billion. Pricing is enterprise and quote-based, with no public numbers.
Cresta is the pick when your strategy is making human agents better rather than replacing them, especially in revenue-bearing conversations like sales and retention where a slightly better sentence is worth real money. If you want humans out of the loop entirely, look at the autonomous-agent specialists; if you want your hundred agents performing like your best ten, Cresta was built for exactly that.

Parloa is an enterprise platform built for the hardest support channel of them all: the phone. It focuses on natural-sounding, low-latency voice agents that can actually hold a conversation, and it wraps them in what it calls an AI Agent Management Platform, tooling to build, simulate, test, and safely release fleets of agents at contact-center scale. Though voice is its heart, Parloa has grown multimodal, extending the same agents to chat, WhatsApp, and Microsoft Teams, always aimed at high-volume enterprise contact centers rather than small teams.
The founders come by their voice obsession honestly. Parloa was started in 2018 in Berlin by Malte Kosub and Stefan Ostwald, who had previously built voice experiences and were among the first developers in Germany to create applications for Amazon's Alexa. That head start on talking machines shows up in a product designed to make phone automation feel human instead of robotic.
Investors have noticed in a big way. Parloa became one of Germany's newest unicorns in 2025 and then roughly tripled its valuation to around three billion dollars in early 2026, all while surpassing fifty million dollars in annual recurring revenue, a remarkable clip for a company automating something as unglamorous as inbound calls. Its commercial model is outcome-based, so customers pay for successfully resolved conversations rather than per minute or per seat, and a handoff to a human does not trigger the full charge.
Enterprises like Allianz, Booking.com, HealthEquity, SAP, and Decathlon trust it with serious call volumes across insurance, travel, and well beyond. Pricing is sales-led and geared toward large organizations handling hundreds of thousands of calls a year. If your support pain is concentrated squarely on the phone and you want AI that sounds genuinely natural even at massive scale, Parloa is a specialist built precisely for that particular fight.
