Posh (Posh AI, legally Posh Technologies) is a Boston-headquartered, remote-first conversational and agentic AI company founded in 2018 by Karan Kashyap and Matt McEachern out of MIT's AI lab. Posh builds AI purpose-built for regulated financial institutions — banks and credit unions — combining voice, digital, knowledge and outreach agents on a single governed platform driven by its proprietary REALM reasoning engine and "Operating Procedures" that pair LLM flexibility with code-level policy control. Its product line spans a Voice Assistant for phone banking, a Digital Assistant for web and mobile chat, a Knowledge Assistant for employee search, Posh Answers for website search, Posh Outreach for proactive campaigns, Posh Simulator for role-play training and Posh CoachQA for quality assurance, all managed from the no-code Posh Portal. Posh reports 125+ financial-institution clients and 300+ deployments, and integrates with core banking and contact-center platforms including Symitar, Fiserv, Corelation, Jack Henry, NICE CXone, Genesys Cloud, RingCentral and Five9. Posh operates a private, customer-facing HTTP API behind its portal for custom reporting and system integration; that API's reference is not published publicly.
Posh is listed with 1 API on the APIs.io network. Tagged areas include Artificial Intelligence, Conversational AI, AI Agents, Banking, and Credit Union.
Posh’s developer surface includes signup flow, engineering blog, support, and 17 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Banking & Open Finance regime, so
Regulatory Posture carries 15 points of the composite.
If this regime is wrong for your business, say so on your
provider repo — the
applicability map is public and we will correct it.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
The six quality facets above are damped to 85 points between them,
because the conditional facet above carries the other
15. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 85% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.

description: 'Posh''s customer-facing HTTP API, served from the same gateway that backs the Posh Portal. Posh describes
it on its portal page as a "powerful API" that "automates custom reporting" and connects the portal directly to internal
tools and systems. The gateway is live and answers unauthenticated requests with a structured JSON error envelope, but
its reference surface at /api-docs is RBAC-gated (HTTP 403 "RBAC: access denied") and no OpenAPI/Swagger document is published
on any Posh host.'

baseURL: https://api.poshdevelopment.com/api/v1
x-ownership: 'OWNERSHIP CHECK (STEP 0c). The API and the Posh Portal are served from poshdevelopment.com, not posh.ai. That
is justified from Posh''s own pages: www.posh.ai/portal links directly to https://app.poshdevelopment.com/login as the
portal sign-in, and www.posh.ai''s own homepage loads its Posh Answers embed from https://poshie-chat-api.poshdevelopment.com/entry-answers.js.
That shipped loader additionally hard-codes Posh''s development, staging and UAT hosts under poshdevelopment.com and posh.build.
poshdevelopment.com is Posh''s product domain; posh.ai is its marketing domain.'
