Bland AI vs Vapi: pricing, features and which to choose

Bland AI’s documented origin story begins with a 2023 pivot during Y Combinator, when the company says it committed to building its own voice, language-model, speech-to-text, and text-to-speech stack. Its About page says the startup spent $1 million on GPUs despite having $400,000 in the bank, then reached $2 million in annual recurring revenue within four months after a $60,000 billboard campaign. Bland reports more than 740 million calls handled, 66 million calls per month, about 100 employees in San Francisco, and more than $50 million raised. Its backers include Y Combinator, Scale Venture Partners, Emergence Capital, Z Fellows, Team Ignite Ventures, Max Levchin, and Jeff Lawson. Its audience spans developers, teams, and regulated enterprises.

A typical Bland workflow begins by defining an agent prompt, then adding conversational pathways that map questions, decisions, and handoffs. Teams can connect knowledge bases, integrations, automations, webhooks, and API calls before assigning inbound or outbound numbers through Bland, Twilio, or SIP. During a call, the agent follows configured branches, retrieves relevant information, schedules an appointment where available, sends an in-call message when supported, and transfers the caller to a person when necessary. Afterward, teams can review transcripts, summaries, outcomes, and usage data. Enterprise customers can configure alarms for call length, API errors, latency, sentiment, silence, transcription quality, engagement, and interruptions. Adaptive resumption and node-scoped interruptibility let conversations resume and react at specific workflow steps.

Bland AI’s main limitation is cost structure: Start charges $0.14 per connected minute, while carrier fees, SMS, outbound minimums, transfers, and Norm can add separate charges. Build costs $299 monthly, which may outweigh its bundled pricing for small workloads. Vapi advertises $0.05 per minute for platform infrastructure, but teams separately select and pay for language, speech, voice, and telephony providers, increasing control and billing complexity. Retell advertises about $0.07 per minute for voice infrastructure and likewise separates provider costs, with estimated production totals of $0.11 to $0.25 per minute. Bland includes LLM, STT, and TTS in its stated rate, but reserves SSO, BAA, data residency, and advanced safeguards for Enterprise. Choose Bland for structured, high-volume business calls and consolidated AI billing; choose Vapi or Retell for component-level control.

Vapi is a San Francisco company that sells the plumbing behind AI phone agents. Jordan Dearsley and Nikhil Gupta, classmates from the University of Waterloo, went through Y Combinator with a productivity app called Superpowered. In 2023 Dearsley built an AI therapist to talk to on walks, found that startups wanted the low-latency voice layer underneath it, and the pair relaunched as Vapi in 2024. In May 2026 it raised a $50 million Series B led by Peak XV at about a $500 million valuation, bringing total funding to $72 million, according to TechCrunch. The company says it has handled more than 1 billion calls and has over 1 million developers on its self-serve platform. Enterprise customers include Amazon Ring, which routes all of its inbound support calls through Vapi, plus Intuit, New York Life and Kavak.

A Vapi agent is a configuration that wires together three parts: a transcriber that turns caller speech into text, a language model that decides what to say, and a voice that speaks the reply. You set these up in the dashboard or through the API, write a system prompt, and attach tools so the agent can book appointments, look up orders or transfer to a human. Vapi supplies phone numbers, or you bring your own through Twilio, Vonage or SIP. Squads let several specialised agents hand a call to each other. Testing and simulation features run scripted calls against an agent before it reaches customers, and observability dashboards flag failed calls. Web and mobile SDKs cover in-app voice. Common uses are customer support lines, lead qualification, appointment scheduling and outbound sales calls.

Vapi expects you to write prompts, configure tools and read logs, so non-technical teams usually need a developer or an agency to get an agent into production. Total cost is harder to predict than a flat per-minute rate because it depends on which models you pick. Retell AI offers a similar developer platform with simpler bundled pricing and strong turn-taking, and Bland AI targets enterprises that want a more managed service with its own hosted models. ElevenLabs Agents is the easier choice if you already use ElevenLabs voices and want one vendor. Pick Vapi if you have engineers, expect high call volumes and want freedom to change speech, language and voice providers as models improve. Choose Retell or a no-code tool if your team wants a working receptionist this week without touching an API.
