Company profile
researched Aug 2026mdhub is a San Francisco-based health technology company that sells an AI-native operating system for behavioral health clinics, combining a purpose-built EHR, CRM and revenue cycle management (RCM) system with software "AI workers" that execute admissions, clinical documentation and billing tasks alongside clinic staff [0][6]. The company markets three named AI workers: Emma, an AI clinical assistant that drafts structured session notes, applies CPT codes, pre-charts sessions and assists with treatment planning; Sarah, an AI admissions coordinator that answers inbound calls, texts and faxes 24/7, collects intake details, verifies insurance eligibility and matches and schedules patients with providers; and Eric, an AI billing agent that handles coding, claims submission, denial management and prior authorizations [0][6]. The website also references Remi, an AI phone agent used by a customer for lead qualification [0].
The platform is positioned as a replacement for the fragmented legacy stack that mid-to-large behavioral health clinics run on, with admissions, clinical and billing work flowing through one system and modules that can be used independently or together [0][6]. mdhub's EHR product covers charting and notes, scheduling, billing and claims, patient intake, insurance and prior authorization, reporting and analytics, secure HIPAA-compliant messaging, care plans, a branded patient portal, provider management and credentialing, workflow automation and integrated telehealth [4]. The company advertises enterprise-grade security, HIPAA compliance and SOC 2 certification [0]. A companion mobile app on Google Play records in-person or virtual patient conversations and returns transcripts, structured notes and patient-friendly summaries via a secure portal; the listing states the product is a documentation and workflow support tool that does not provide clinical decision support or medical advice [3].
Earlier positioning centered on a single clinical AI assistant for mental health clinicians that captured the patient-clinician conversation to automate clinical documentation, after-visit reports, pre-charting and treatment planning [7]. Successive YC launches trace the progression from "clinical AI assistant for mental health clinics" to "AI agents for mental health clinics" to the full AI-native operating system [6].
Founding story
Co-founders Dominik Middelmann (CEO) and Efrén A. Lamolda (CTO) had worked together since 2018 at a hyperscale start-up, where Efrén was a founding engineer and Dominik the first hands-on operator. Efrén holds an MSc in Computer Science; Dominik was previously Director of Product Operations at TIER Mobility and worked at BCG, and holds a Masters in Management from London Business School. They founded mdhub in 2023 in San Francisco to address the administrative burden that leaves mental health clinicians spending only about half their time with patients [6][7].
Business model
B2B software sold to behavioral health clinics, characterized as subscription SaaS with a services and consulting element [5]. Customers range from solo and group practices to enterprise, CCBHC and multi-site behavioral health organizations, and mdhub also runs a structured four-week implementation program covering data migration from an existing EHR, workflow and template configuration, role-based staff training and a supported go-live with a dedicated implementation manager [0][4].
Software platform sold to clinics on a subscription basis, with modular AI workers (admissions, clinical, billing) that can be purchased independently or as a unified clinic operating system, plus implementation and onboarding support [0][4][5].
Traction
The company website states that more than 10,000 clinicians nationwide use mdhub and that 98% of clinics report improved efficiency [0]. In its full-stack launch, mdhub reported that Emma had been used in over 3 million patient sessions across more than 1 million patients in the prior year, returning over 500,000 hours of administrative work, and that Sarah had booked over 100,000 patients into care [6]. Customer references include Family Care Center, whose director cited more than 600 clinicians using mdhub and over 50,000 sessions per month, and University Health Kansas City, which reported documentation savings of 6 to 20 minutes per note [0]. The Google Play app listing shows 1,000+ downloads [3]. Marketed outcome claims include 30% more patients scheduled, a 55% reduction in denials, roughly two clinician hours saved daily, a 70% reduction in documentation time per provider and 40% lower administrative cost per patient visit [0][4].
Latest developments
mdhub launched its full stack as an AI-native operating system for behavioral health clinics, adding three products beyond its AI workers: mdhub EHR (documentation, intake, treatment planning, e-prescribing and billing), mdhub CRM (admissions pipeline and automated follow-up) and mdhub RCM (claim submission through collections) [6]. A third-party market-data profile records an April 2026 signal describing the launch of an AI-native platform for behavioral health clinics [5]. The company is hiring for growth, engineering, deployment and sales roles in San Francisco [6].
▸Full profile — market position, technology, go-to-market, geography, history
Market position
Categorized as a vertical SaaS and healthcare/life sciences company covering mental health, workflow automation and EHR/EMR, operating at the application layer of AI [5]. It competes in behavioral health documentation and clinic software with companies including JotPsych, Upheal and Mentalyc [5]. mdhub differentiates from AI scribes and point solutions by claiming coverage of the full clinic stack and states that hundreds of mid-to-large behavioral health clinics use the platform, including some of the largest organizations in the country [6].
mdhub positions itself as an AI-native operating system rather than an existing EHR with AI added or a single-purpose point solution: AI workers are built into the same platform as the EHR, CRM and RCM so admissions, clinical and billing tasks move end to end without handoffs between separate systems [0][6]. The company emphasizes behavioral-health-specific design over generic AI tooling and frames product development around clinician trust, asking whether a feature fits real clinical workflow and reduces rather than adds burden [2][7].
Technology
Application-layer AI built on ambient capture of clinical sessions and agentic automation of clinic workflows: audio recording of in-person and virtual visits converted into transcripts, structured clinical notes and patient-facing summaries; CPT coding and note formatting for billing; voice, text and fax handling for inbound patient inquiries; real-time insurance eligibility checks and automated prior authorization; and claims submission, denial tracking and payment reconciliation [0][3][4]. These agents operate natively inside mdhub's own EHR, CRM and RCM rather than as add-ons to third-party systems, with clinician review and sign-off, auditability and regulatory compliance built into the workflow; the company states HIPAA compliance and SOC 2 certification [0][4][6].
Go-to-market
Direct enterprise sales through demo requests and self-service sign-up on the company website, supported by use-case and buyer-segment landing pages (chart audit, medication refill line, telehealth, referral management, scheduling and intake, practice management, billing and RCM, AI medical scribe) and comparison guides on behavioral health EHR software [0][4]. The company hires commercial and deployment-oriented roles in San Francisco, including growth strategist, forward deployed engineer, deployment strategist and account executive [6]. Customer testimonials from named clinic operators such as Radial, University Health Kansas City, Family Care Center and Love on the Autism Spectrum are used as references [0].
Behavioral and mental health providers, including mid- to large-sized behavioral health clinics and some of the largest such organizations in the US, as well as group practices, enterprise providers, CCBHCs, therapists, psychiatrists and PMHNPs [0][6].
Geography
Headquartered in San Francisco, California (2261 Market Street #10462, San Francisco, CA 94114), serving clinicians in the United States [0][2][3][5][6].
History
Founded in 2023 and based in San Francisco, mdhub launched its clinical AI assistant for mental health clinicians and participated in Y Combinator's Summer 2024 batch, with Garry Tan listed as primary partner [6][7]. By mid-2024 the company reported an eight-person team and said its assistant had saved clinicians over 100,000 hours of administrative work in its first six months [7]. Successive launches expanded from a clinical AI assistant to AI agents for mental health clinics and then, in 2026, to a full AI-native operating system with the addition of mdhub EHR, mdhub CRM and mdhub RCM [6]. Team size was listed at 15 on the YC profile [6].
