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.

Vapi is a developer platform for voice AI agents. Rather than selling a finished support bot, it sells the orchestration layer: an API and SDKs that wire together speech-to-text (Deepgram and others), any major LLM (OpenAI, Anthropic), text-to-speech (ElevenLabs, PlayHT, Cartesia), and telephony (Twilio, Vonage, Telnyx) into a low latency phone agent. Support teams meet Vapi indirectly, as the engine behind custom-built inbound support lines, appointment desks, and agencies' white label voice products.
Founders Jordan Dearsley and Nikhil Gupta went through Y Combinator in 2021 with a productivity app called Superpowered, then pivoted to voice infrastructure in 2023 after Dearsley built himself an AI phone bot to think out loud with. It worked: Vapi reports over a million developers and a billion calls handled. It raised a $20 million Series A led by Bessemer in December 2024, then a $50 million Series B in May 2026 at a $500 million valuation, roughly $72 million total. Amazon chose Vapi for its Ring division after evaluating over 40 rivals.
Pricing starts at $0.05 per minute for the platform itself, with SMS at $0.005 per message. Provider costs (speech, LLM, voice, telephony) are passed through at cost, or drop to zero if you bring your own API keys. Realistic all in costs run $0.07 to $0.25 per minute. Ten concurrent calls are included, extra lines cost $10 monthly, and compliance add-ons are priced like enterprise software: HIPAA at $2,000 monthly, zero data retention at $1,000 monthly.
Choose Vapi if you have engineers and want maximum control over every layer of a support voice agent, with the freedom to swap providers as models improve. Skip it if nobody on your team writes code, or you want a vendor accountable for resolution rates rather than infrastructure.
