boost.ai comes from Sandnes, Norway, where founder Lars Ropeid Selsås started in 2016 by automating customer interactions for a local bank. That origin explains everything about the product: it is conversational AI built for institutions that cannot afford a creative answer, and Nordic banks and insurers were the proving ground. Customers today include Nordea, Santander, DNB, Telenor, Vodafone, and Metro Bank, and the platform claims more than 600 live AI agents handling over 150 million automated conversations a year.
Technically, boost.ai's signature move is the hybrid: deterministic natural-language understanding that behaves predictably at thousands of intents, combined with generative AI where flexibility helps, all wrapped in governance controls. That lets a compliance officer sign off on what the agent is allowed to say while the agent still handles the long tail of phrasing real customers use. It covers chat and voice, integrates with contact-center platforms like Genesys, Five9, and Amazon Connect, and even supports Nordic authentication systems like BankID, a detail that says a lot about who it serves.
The company took a majority investment from private equity firm Nordic Capital in 2021 and sells the way you would expect an enterprise Scandinavian vendor to sell: quote-based pricing, no public price list, proper procurement. An unusual cultural artifact is its certification program, with thousands of certified AI trainers among its customers' staff, reflecting a philosophy that the client team, not the vendor, should run the agent day to day.
Pick boost.ai if you are a bank, insurer, telco, or public-sector organization that needs high-accuracy automation with auditable behavior. It is not the tool for a startup wanting a widget by Friday; it is the tool for the organization whose regulator reads the transcripts.

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.
