Comparing Posh AI and Vapi? 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.

Posh AI builds an agentic AI platform for banks and credit unions, covering both sides of the desk. Member facing products include a Voice Assistant for 24/7 phone support, a Digital Assistant for web and mobile chat, Posh Answers for help center search, and Posh Translate for live spoken interpretation. Employee facing tools include a Knowledge Assistant, a training Simulator, and CoachQA for conversation quality and compliance monitoring. All agents run inside Operating Procedures, Posh's framework for pairing LLM flexibility with code level control.
Karan Kashyap and Matt McEachern founded Posh in 2018 out of MIT, where both studied AI, and the Boston company remains independent and active as of mid 2026, with no acquisition on record. It raised a $27.5 million Series A led by Canapi Ventures in December 2021, with credit union industry funds Curql Collective and CMFG Ventures participating, and third party trackers put total funding around $45 million. Posh serves more than 100 financial institutions, including VyStar Credit Union, Citadel Credit Union, Camden National Bank, and Hudson Valley Credit Union. In late 2025 it relaunched Knowledge Assistant as an AI native workspace for agentic action.
Posh publishes no pricing. Everything is quote based per institution, shaped by asset size, products licensed, and integrations. The company leads with customer ROI stories instead, like Citadel's reported $660,000 in annual savings, so treat those as marketing anchors and negotiate accordingly. Expect a demo led sales cycle and implementation work that depends on your telephony and core stack; nothing about the process is self serve.
Choose Posh if you are a community financial institution that wants credible voice and chat automation plus employee copilots from a team that only does banking, with prebuilt hooks into cores like Fiserv, Symitar, and Corelation. Skip it if you are not a bank or credit union, or if you need transparent self serve pricing.

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.
