Penciled
Penciled is an AI front office assistant for physical therapy clinics. It plugs into the clinic's existing EHR - primarily WebPT - to text and call patients, book and confirm appointments, complete plans of care, send reminders, and fill last-minute cancellations from an automated waitlist. Founded by Shawn Shivdat and Deniz Sert in the Y Combinator W24 batch, the company now serves 200+ providers across 50+ clinics and books thousands of appointments a month.
EliseAI
EliseAI is a New York-based artificial intelligence company that builds conversational and agentic AI to automate the routine, high-volume communication work of two administratively heavy industries: rental housing and healthcare. Its assistants answer calls, emails, texts and chats around the clock - scheduling tours, handling maintenance and renewals, collecting rent, and booking patient appointments - so property and clinic teams can focus on people rather than paperwork. Founded in 2017 as MeetElise, the company crossed $100M in annual recurring revenue, serves roughly 70% of the 50 largest U.S. rental housing operators, and reached a $2.2 billion valuation with its 2025 Series E led by Andreessen Horowitz.
Vital Interaction
Vital Interaction is an Austin, Texas healthcare technology company that blends patient data, business intelligence, and workflow automation to help medical practices communicate with patients across text, voice, and email. Founded in 2009, its platform automates appointment reminders, recalls, reactivations, referrals, and surveys so practices can cut no-shows, close care gaps, and re-engage patients. The company says it serves more than 13,000 providers and delivers over 40 million personalized messages a year to more than 5 million patients, and in early 2024 it raised a $15 million Series A led by Next Coast Ventures.
Syllable
Syllable is a Mountain View, California company that builds, deploys, and manages AI voice and text agents, originally to automate patient communication for health system call centers and medical practices. Founded in 2016, it has expanded from healthcare-specific natural language understanding into a broader, model-neutral agentic platform that lets organizations build agents once and run them across any cloud with governance, analytics, and compliance built in. The company has raised roughly $81.7M+ across Seed through Series C, counts investors like TCV, Oak HC/FT, Verily, and Northwell, and acquired Actium Health in 2024.
Tellescope
Tellescope is a HIPAA-compliant digital health platform that unifies patient communication, intake, scheduling, and workflow automation into a single, developer-friendly system. Built for digital health startups and modern clinics, it lets care teams reach patients across SMS, email, chat, and video, automate repetitive workflows without code, and plug into EHRs and clinical tools through an API-first architecture - so teams can launch faster and scale personalized care without stitching together generic sales software.
Abdul Jamjoom
Abdul Jamjoom is the co-founder and CEO of Arini, a San Francisco startup building an AI receptionist that answers phones, books appointments, and handles patient communication for dental practices around the clock. A Harvard computer science graduate and former search and applied-AI engineer at the enterprise messaging company Threads, he teamed up with his high-school friend Rami Rustom - the pair met in Jordan - to attack a market they found by literally walking into dental offices and watching front desks melt down. Backed by Y Combinator (W24), Arini turns the $7B-a-year dental front-desk problem into software that, in Jamjoom's words, just gets the job done.
Sebastian Coates
Sebastian Coates is the CEO and co-founder of Tellescope, a HIPAA-compliant, API-first patient communication and CRM platform used by more than 150 digital health organizations. A Tufts computer science and mathematics graduate who once wrote software for the Apple Watch and prototyped blockchain systems for clinical trials at Vertex Pharmaceuticals, he started Tellescope in 2020 with co-founder Derek Strauss to give telehealth companies a developer-friendly tech stack for managing patients across SMS, email, voice, and secure messaging. Notably, he has kept the company lean and profitable rather than chasing oversized venture rounds.
NexHealth
NexHealth is a San Francisco-based health technology company building the patient experience platform for medical and dental practices. Its software gives doctors EHR-integrated online scheduling, patient messaging, digital paperwork, recalls, reviews and payments, while its Universal API and proprietary Synchronizer let developers read and write data across 20+ practice management systems in real time. Founded in 2017 by Alamin Uddin and Waleed Asif, NexHealth reached unicorn status in 2022 with a $125M Series C at a $1B valuation and serves more than 10,000 practices.
Medsender
Medsender is a New York-based healthcare AI company building the workflow automation platform for medical practices. It started by fixing the fax - the stubborn backbone of healthcare communication - turning inbound faxes, referrals and documents into structured data that drops straight into the patient chart. Today its AI Medical Assistant, MAIRA, answers patient phone calls 24/7 in 15+ languages, and the company says it serves thousands of providers across all 50 states. Medsender raised a $5M Series A led by Ballast Point Ventures in early 2025.
Salman Haque
Salman Haque is co-CEO of Medsender, the New York healthtech company tearing the fax machine out of American medicine. A Harvard economics grad who cut his teeth in venture and private equity before running operations at the pharmacy startup Capsule, Haque joined Medsender and helped turn a HIPAA-compliant fax tool into an AI workflow platform now used by healthcare providers across all 50 states. Medsender went through Y Combinator's W24 batch, debuted on the Inc. 5000 at #550 in 2025, and raised a $5M Series A led by Ballast Point Ventures.
