Simran K. Co-founder & CEO, NextDimension AI - [Customer stories](https://dmand.ai/customers) Why a context layer ## Without healthcare context, an AI assistant answers from press releases and switchboards Public pages name a CIO from two years ago and stop at the hospital door. The context layer places every site under its health system and every person at the site where they work today. Assistant alone Public web pages Who runs IT at each Regional Health hospital? I found a 2024 press release naming Regional Health's CIO. I couldn't find a list of its hospitals or the IT leader at each one. You could try the main switchboard. - Press release - Hospital homepage - Main switchboard - No hospital list - No site - No verified contact With Dmand AI Resolved records Who runs IT at each Regional Health hospital? - Regional Health, IDN - Metro Hospital, Hospital - Chief Information Officer - Email verified - Direct dial verified - North Hospital, Hospital - Chief Information Officer - Email verified - Direct dial verified - Every hospital - The leader at each site - Verified contact Inside the context layer ## The context layer stacks healthcare data, org context and verified contacts in three layers Each layer adds what the one below cannot. The data says who exists, the context says how they connect, and the reach says how to contact them. Illustration: three stacked layers lit by a beam of light. The data layer is a field of record columns. The context layer is an IDN wired to its hospitals and sites, with people tied to the sites where they work and a buying signal on one hospital. The reach layer is a set of people pins, one with a verified email and a direct dial. The layer chosen in the list is the one lit. 1. 01 · Data layer 7.4M+ HCPs by NPI, 11M+ healthcare executives and 997K+ sites of care, from integrated delivery networks down to 235K+ solo practices. [Browse the healthcare database](https://dmand.ai/data) 2. 02 · Context layer 3. 03 · Reach layer Where the data comes from ## Dmand AI combines NPPES, CMS and PECOS records with its own healthcare data into one profile per HCP, site and health system Public registries disagree on names, addresses and affiliations. Dmand AI matches them into one record, then adds what no registry holds: the org hierarchy, the people at each site, buying signals and verified contacts. - People linked by org tree, not by email domain - Site-level affiliations, including secondary practice locations - Validated emails and direct dials from healthcare-specific sources Public records - NPPES NPI Registry - PECOS enrollment - CMS Provider of Services - CMS Doctors and Clinicians - Medicare cost reports - CMS Open Payments - Medicare Part D prescribers - Medicare claims - IRS Form 990 filings - PubMed and ClinicalTrials.gov Dmand AI - Org hierarchy model - Site-level affiliation mapping - Healthcare waterfall enrichment - Email and direct dial validation - Relationship graph - 80+ buying signals - AI web research Illustration: ten public records and seven Dmand AI sources run as lines of light into one point, which resolves into a single record for an illustrative cardiologist: the site of care where they practice, their medical group, hospital and health system, a buying signal, and a verified email and direct dial. - 7.4M+ HCPs One profile per NPI, with practice locations, affiliations and contacts. - 997K+ Sites of care Unique locations across nine segments, from hospitals to pharmacies. - 181K+ Medical groups Single-site and multi-site groups, tied to the physicians who practice there. - 124K+ Parent organizations With 11M+ affiliated contacts, from health systems to practice groups. - 22K+ Hospital outpatient units Outpatient departments, clinics and inpatient units modeled under 6.2K+ hospitals. How it works ## Dmand AI works inside Claude in four steps: find the accounts, map them, reach the buyers and start outreach One conversation takes you from a region to a first email. Each step picks up the answer before it, so nothing is copied between tools. Illustration of Dmand AI inside Claude, step 1: asked which Ohio health systems opened new outpatient sites this quarter, Claude searches Dmand AI, checks buying signals and lists Regional Health, Valley Health and Northern Health with the new site at each, then offers to map how Regional Health is organized. All names are placeholders. 01 ### Find the accounts worth calling Ask for health systems, hospitals or groups by region, type or buying signal. You get the accounts and the reason to call now. 02 ### Map each account from IDN to site of care Hospitals, medical groups and outpatient sites in one tree, with the HCPs and executives who work at each one. 03 ### Reach the people who decide The buying committee at the right site, with verified work emails and direct dials. 04 ### Start outreach from the answer Save the people to a Dmand AI list, draft the first email in Claude and run the sequence in the same login. Who it’s for ## Teams that sell to health systems, medical groups and physician groups each ask it a different question One illustrative question per team, with placeholder accounts. The answer comes back resolved, placed and reachable. ### Health IT and services Buying committees by hospital, with the EHR in place and the signal that says when to call. [See Dmand AI for Health IT](https://dmand.ai/solutions/health-it) Illustration: asked which Regional Health hospitals still run an on-premise EHR and who leads IT at each one, Dmand AI returns the Chief Information Officer at Metro Hospital, the Chief Medical Information Officer at North Hospital and the IT Director at Community Hospital, each with a verified email or direct dial, and flags a new IT leader at Metro Hospital. Circle Health > I like Dmand AI’s extremely curated and comprehensive healthcare database, which you won’t find on any other platform with this level of detail. The ability to filter by specialty, location, independent physician or not, and many others is incredibly useful. _Anupam D.

Email [hello@dmand.ai](mailto:hello@dmand.ai) or book a demo with our team. **What is a context layer for healthcare AI?** A context layer is the verified data an AI assistant or agent reads before it answers, so it works from records instead of guessing from web pages. For healthcare it means every US health system, hospital, medical group, site of care, HCP and executive resolved into one org hierarchy, with affiliations, buying signals and verified contacts. Dmand AI serves it to people in its app and to assistants and agents over MCP and a REST API. **Is a context layer the same as a semantic layer?** They are related. A semantic layer defines what the fields in your own warehouse mean so tools query them the same way. A context layer brings outside knowledge your systems do not hold, here the US healthcare market resolved into records and relationships, and serves it to AI assistants and agents in a form they can reason over. **Does Dmand AI return verified emails and phone numbers inside Claude?** Yes. Ask Claude for the contacts and the Dmand AI connector returns verified work emails and direct dials in the chat, from the same healthcare waterfall enrichment the app uses. Searching is free and a credit is used only when a contact is found. **Which AI assistants and agents can use Dmand AI today?** Claude on the web and desktop through the Dmand AI MCP connector, plus the Dmand AI app and the REST API. ChatGPT, Gemini, Claude Code, Cursor, Codex and custom agents are in early access on the same account. **What is a healthcare MCP server?** An MCP server exposes a data source to AI assistants through the Model Context Protocol, so the assistant can search it and act on the results. Dmand AI is a healthcare MCP server: it gives an assistant search over US health systems, hospitals, medical groups, sites of care, HCPs and executives, the org hierarchy around each, and verified contacts. **What healthcare data does the context layer include?** 1.6K+ health systems and integrated delivery networks (IDNs), 6.2K+ hospitals, 181K+ medical groups and physician groups, 124K+ parent organizations, 997K+ sites of care, 235K+ solo practices, 7.4M+ HCPs and 11M+ healthcare executives, each placed in a parent-child org hierarchy with physician-to-site, physician-to-group and executive-to-organization affiliations, plus 80+ buying signals and verified contact coverage. **Where does Dmand AI’s healthcare data come from?** Public registries and filings, including the NPPES NPI Registry, CMS Provider of Services, Doctors and Clinicians and cost reports, PECOS enrollment, CMS Open Payments, Medicare Part D and claims data and IRS Form 990 filings, research sources such as PubMed and ClinicalTrials.gov, and ongoing web research. Dmand AI resolves them into one record per person and organization. Contacts come from healthcare-specific enrichment sources and are verified before they are returned. **How is this different from searching NPPES or an NPI database directly?** NPPES returns one provider record per NPI as it was registered, often with an old address and no employer. Dmand AI starts from those records and adds where the physician practices today, the medical group, hospital and IDN above that site, the executives around them and a verified way to reach them, all searchable in plain English from your assistant. **Can my own AI agent use Dmand AI?** In early access, yes. Any MCP-compatible client or healthcare AI agent connects to the same Dmand AI account and credit balance that powers the Claude connector. Join the list and name the client you use. **What does the context layer cost?** The trial is 30 days free, self-serve, with no credit card. Paid plans start at $249 per user per month and include credits; searching from any surface is free and a credit is used only when a verified contact is returned. The big picture All of US healthcare, in context. Every IDN, hospital, medical group and site of care in the country, with the people who work there, inside the assistant your team already opens.
