Entry priceFrom $499/mo billed annually (Growth, 100 interviews)Full pricing detail

Voice AI recruiter that conducts natural, adaptive screening interviews with candidates around the clock, then scores and summarizes them and pushes results into your applicant tracking system.

Ribbon is a voice artificial intelligence recruiter that conducts job screening interviews at scale. Founded in 2023 in Toronto by Arsham Ghahramani, an Amazon AI alum, and Dave Vu, a talent leader, the company raised more than eight million dollars in a round led by Radical Ventures in 2025. Its AI Interviewer replaces the initial phone screen with an adaptive agent that candidates can meet around the clock by voice or video, so a role that once waited days for a recruiter to schedule a call can be screened in minutes.

The interview itself is the core of the product. Ribbon's agent holds a natural, adaptive conversation that responds to candidates in real time and asks relevant follow up questions, in more than ten languages and with voices from ElevenLabs and OpenAI, with cheating detection to keep the process fair. A business sets up an interview flow for each role, with the role context, the questions to ask, the interviewer's personality and the scoring, and invites candidates by email, SMS or WhatsApp.

For the hiring team, Ribbon turns each conversation into a decision ready output. It scores every interview, lets teams watch recordings and rank candidates, and writes completion status, scores and a link back to more than sixty applicant tracking systems, including Greenhouse, Workday, Ashby, UKG and Workable, moving each candidate to the next stage. A human recruiter reviews the results and makes the final call. A public API manages interview flows and interviews, and a sourcing assistant searches candidate databases for recruiters to invite.

Access runs through Admin and Member roles with view or edit rights per interview flow and single sign on through Google Workspace, Okta or Azure Active Directory, and Ribbon states SOC 2 Type I certification with Type II in observation, GDPR compliance and a New York City Local Law 144 bias audit. Plans start at $499 a month billed annually with a seven day free trial. Ribbon is built for high volume, high turnover hiring in industries like manufacturing, airports, quick service restaurants and healthcare staffing.

Target customers

Deployment options

Integrations

Integrates with more than forty five applicant tracking systems including Workday, Lever, Greenhouse, and BambooHR, plus meeting tools such as Zoom, Google Meet, and Microsoft Teams, so screening results and summaries sync into existing hiring workflows. Offers a developer application programming interface (API) for interview flows, interview links, the Talent Hub, and scoring. No self hosted or on premises option.

In practice

A quick service restaurant chain gets thousands of applicants a month and cannot screen them all by hand. Ribbon interviews every candidate by voice within minutes of applying, then hands recruiters a ranked, summarized shortlist to act on.

A working parent can only job hunt after the kids are asleep. With Ribbon, they complete a real screening interview at two in the morning, on their own schedule, instead of waiting weeks for a recruiter to call.

A staffing agency wants faster submissions without adding headcount. Ribbon runs first round screens around the clock, syncs scores and summaries into the agency's applicant tracking system, and frees recruiters for higher touch work.

Agentic Index coverage score

7.0 / 14 capabilities · 50%

Integrations & Tool Calling	Full
A named catalog that writes to outside systems. Through Kombo, Ribbon connects to more than 60 applicant tracking systems (Greenhouse, Workday, Ashby, UKG, Workable and others), pulls open jobs, and writes back interview completion, overall scores and a link to the interview, moving the candidate to a specified stage; outreach runs over email, SMS and WhatsApp. SourceRibbon, docs.ribbon.ai (ATS Integrations) and ribbon.airead 2026-09-28
Workflow Orchestration	Partial
A fixed interview pipeline with a configurable question list. An interview flow sets the role context, an ordered list of questions (five by default for recruitment), a personality, a language and scoring, and completed interviews are scored and sent to the ATS; no branching, retry or routing step is documented, so the orchestration stays inside one packaged use case. SourceRibbon, docs.ribbon.ai (Interview Flows, ATS Integrations)read 2026-09-28
Knowledge Grounding & RAG	Partial
Role context supplied per interview, not a maintained knowledge base. Each interview flow carries the role title, company name, location and job description that the interviewer draws on, which is context assembled for each run; no document store, index or retrieval over the customer's knowledge is documented. SourceRibbon, docs.ribbon.ai (Interview Flows)read 2026-09-28
Human Oversight & Guardrails	Partial
Decisions reserved to people. Recruiters review scored interviews and make the hiring call, and sourcing drafts invitations that a recruiter previews and sends; nothing holds an agent action for sign off inside the interview itself. SourceRibbon, docs.ribbon.ai (Sourcing, Teams and Permissions)read 2026-09-28
Security, Identity & Governance	Full
Access and compliance are both documented. On access, there are Admin and Member roles with View or Edit permission per interview flow, admin only control of API keys and settings, and SSO through Google Workspace, Okta and Azure Active Directory (SAML on Enterprise). On compliance, the homepage states SOC 2 Type I certified with Type II in observation, GDPR, and a 2025 NYC Local Law 144 bias audit, with a Sprinto trust center and a sub-processor list. SourceRibbon, docs.ribbon.ai (Teams and Permissions), ribbon.ai and ribbon.ai/pricingread 2026-09-28
Observability & Auditability	Partial
Per interview recordings and scores, with no view of the agent's steps. Team members with view access watch interviews and see scores, the homepage lists metrics and cheating detection, and the API returns interviews; nothing documented shows the agent's own decisions or the calls it made. SourceRibbon, docs.ribbon.ai (Teams and Permissions, API reference) and ribbon.airead 2026-09-28
Memory & State Persistence	Partial
State within an interview; stored candidates are the data model. Completed interviews and candidates stay in the product for teams to revisit and sourcing keeps its chat history, but these are the product's records of candidates and searches rather than a memory the interviewer reads across sessions with a stated scope and lifetime. SourceRibbon, docs.ribbon.ai (Teams and Permissions, Sourcing)read 2026-09-28
Deployment & Data Residency	Not documented
Hosted only, with no region the customer selects. The sub-processor list names AWS in the United States, Canada and the United Kingdom, Vercel and Supabase in the United States as where Ribbon's service runs, and no plan, including Enterprise, offers a region choice, private cloud or self hosted option; white label branding is presentation, not deployment. SourceRibbon, ribbon.ai/sub-processor-list and ribbon.ai/pricingread 2026-09-28
Prebuilt Agents, Templates & Packs	Partial
Default interview setups the customer configures per role. An interview flow starts from default questions (five for recruitment, three for general interviews) and scoring definitions that the customer edits for each role; these are settings of one interviewer rather than separately adoptable agents. SourceRibbon, docs.ribbon.ai (Interview Flows)read 2026-09-28
Triggers & Channel Coverage	Partial
Interviews start from invitations a recruiter sends. Candidates join by link at any hour, invited by email, SMS or WhatsApp one at a time or in bulk, and webhooks notify other systems when interviews complete; no ATS event, schedule or inbound call starts an interview without a recruiter sending the invitation, since the ATS connection pulls jobs and writes results only. SourceRibbon, docs.ribbon.ai (Sourcing, ATS Integrations, Webhooks) and ribbon.airead 2026-09-28
Model Flexibility & Routing	Partial
The customer picks voices from two third party providers; the language model is fixed. The API's voice list offers ElevenLabs voices (Anna, Anthony, Kate, Amy, Alexandre, Carolina) and OpenAI voices (Onyx, Shimmer), each tied to its provider, while the sub-processor list names OpenAI as the language model with no LLM choice or bring your own key documented. SourceRibbon, docs.ribbon.ai (Supported Voices) and ribbon.ai/sub-processor-listread 2026-09-28
APIs, SDKs & MCP Extensibility	Full
A documented public API for Ribbon's own objects. The API creates, lists and deletes interview flows, creates and reads interviews, revokes recording access and lists teams and members, with an OpenAPI spec and webhooks; the Ribbon MCP server (OAuth 2.1 with PKCE) is read only over ATS pipeline data. SourceRibbon, docs.ribbon.ai (API reference, Webhooks, Ribbon MCP)read 2026-09-28
Testing, Debugging & Optimization	Not documented
No evaluation of the interviewer itself. Scoring grades candidates, cheating detection watches candidates, and the NYC Local Law 144 bias audit the homepage lists (last audited 2025) is a published audit of the product in general, a disclosure rather than an evaluation surface; no test harness, simulated interview or quality gate on the agent's own behavior is documented. SourceRibbon, docs.ribbon.ai (Interview Flows) and ribbon.airead 2026-09-28
Browser & Computer Use	Not documented
No browser, desktop or computer control. Ribbon's interviewer works by voice and video in the candidate's browser session and by email, SMS and WhatsApp, and reaches applicant tracking systems through an API connector. SourceRibbon, ribbon.ai and docs.ribbon.airead 2026-09-28
