Assort Health

AI call center for specialty practice front desks

Our take

Assort Health builds AI voice agents that run the front desk phone lines for specialty medical practices: orthopedics, ENT and allergy, dermatology, ophthalmology, and about 20 other specialties. Its agents answer every inbound call, schedule and reschedule appointments using per-provider rules (which surgeon takes which joint, which payer, which location), triage clinical concerns to staff, and sync everything back to EHRs like Epic, athenahealth, eClinicalWorks, NextGen, and ModMed in real time.

Founded in May 2023 by Jon Wang and Jeff Liu, the company went from $26M raised to a $1.2B valuation in about a year: a $76M Series B led by Lightspeed in September 2025, then a $120M Series C led by Menlo Ventures announced in mid-2026, for $222M+ total. Traction is concrete and named: Michigan Orthopaedic Surgeons attributed $2.3M in added revenue to the platform, ENT MSO SENTA Partners captured $1.3M in recovered appointment revenue, and the company claims 190M+ patient interactions. It is the fastest-growing vendor in specialty patient access, with the usual risks of that speed.

What it does

Voice AI answers inbound patient calls around the clock
Books appointments using per-surgeon, specialty-specific scheduling logic
Triages calls and routes complex cases to staff
Answers FAQs and handles reschedules and referrals
Writes appointments and tasks back to the EHR in real time

Where it's strong

Specialty-specific scheduling logic (per-surgeon rules in orthopedics, ENT, and 20+ specialties) is the hard part competitors gloss over.
Publishes named customer economics, like $2.3M added revenue at Michigan Orthopaedic Surgeons and a 75% drop in call abandonment at Peninsula Orthopaedic.
Heavily capitalized ($222M+ raised, $1.2B valuation) with native integration into 20+ EHRs common in specialty practices.

What buyers should weigh

Founded in 2023, so processes, support, and product maturity are those of a three-year-old company scaling extremely fast.
Raised $222M in roughly 15 months; expect aggressive expansion and possible pricing pressure to grow into the valuation.
Built for specialty practices and MSOs; large hospital contact centers with broad non-scheduling call types are less proven territory.

Latest

In mid-2026 Assort raised a $120M Series C led by Menlo Ventures at a $1.2B valuation, only months after a $76M Series B, bringing total funding above $222M.
