Comparing boost.ai and Voiceflow? Both are AI Agents & Chatbots 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.

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.

Voiceflow is a visual platform for designing, testing, and shipping AI agents across chat and voice. Teams build conversation logic on a collaborative canvas, ground agents in knowledge bases, and deploy to web chat, phone lines via Twilio, and messaging channels. For support work specifically, native integrations let an agent create and update Zendesk tickets, touch Salesforce records, or cancel a Shopify order mid conversation, and anything else is reachable through REST APIs, custom functions, and MCP.
The company was founded in Toronto in 2019, led by CEO Braden Ream, and grew from conversation design tooling into a full agent platform. It has raised $35 million, most recently a $15 million round from OpenView in August 2023 at a $105 million valuation, following a 2021 round led by Felicis. Its own announcements cite more than 130,000 users and customers including The Home Depot, US Bank, BMW, Vodafone, State Farm, and JP Morgan.
Pricing moved to a credit system in April 2025. Third party trackers list a free starter tier, Pro from $60 monthly with 10,000 credits, Business from $150 monthly, and custom Enterprise, with extra editor seats at $50 each. Credits are consumed by every message, call, and model invocation, and reports say agents stop responding when credits run out mid cycle. Note that Voiceflow's own pricing page now steers business buyers toward a sales conversation, so treat published tiers as a floor.
Choose Voiceflow if a mixed team of designers, support leads, and developers needs to own agent behavior together, and you want one canvas covering both chat and voice. Look elsewhere if you want pure per minute phone economics (Retell, Vapi) or a fully managed enterprise deployment; and budget carefully, since seats plus credits add up faster than the sticker price suggests.
