LeanTaaS, which sells capacity and operations software to hospitals, said on September 2, 2026 that it had acquired Aidin, a care-transition platform that helps hospitals move discharged patients into post-acute care. Terms were not disclosed.
Aidin serves more than 200 hospitals across about 20 health systems. It coordinates more than 2 million referrals a year through a network of over 21,000 post-acute providers, such as skilled nursing facilities and home health agencies.
LeanTaaS will connect Aidin with iQueue for Inpatient Flow, its product for managing patient demand and discharge barriers during a hospital stay. The companies did not say whether Aidin will keep its brand.
What Aidin built
Aidin started as a way to help patients and families choose where to go after leaving hospital. When it announced its first funding in 2012, co-founder Russ Graney described it to TechCrunch as something like a Yelp for continuing care, with ratings, reviews and outcome data on nursing homes, health agencies and rehab centres, customised to a patient's condition.
The company has since become a referral and coordination system used by hospital case managers. Moving a patient into post-acute care involves finding a placement, securing payer authorisation, respecting patient choice and keeping several providers informed, often across separate systems. Aidin gives everyone involved a shared workflow.
LeanTaaS said Aidin customers have cut length of stay by an average of 0.86 days and placement time by 50%, saving about $1.7 million per hospital a year on average.
“This acquisition brings that vision to life by helping health systems manage patient flow from admission through transition.”
From a ratings site to a referral network
The problem Aidin set out to solve was readmissions. When it raised its first money, Graney pointed to figures showing that one in four Medicare patients in the US was readmitted to hospital within 30 days, at a cost to hospitals of $17.4 billion. He said there were about 25,000 post-acute care providers in the country, from nursing homes to rehab centres, with large differences in quality between them, and that hospitals could not easily tell patients which ones to choose.
Aidin's early answer was to give patients and families ratings, reviews and outcome data, such as how many of a provider's patients ended up back in hospital. Over time the product moved into the hospital workflow itself, becoming the system case managers use to send referrals, track responses and coordinate a patient's move. LeanTaaS, for its part, says iQueue for Inpatient Flow saves hospitals about $10,000 per inpatient bed a year on average.
Why LeanTaaS is buying
About 40% of discharged Medicare patients need post-acute care, but they account for more than 55% of avoidable hospital days, according to data cited by LeanTaaS. A patient who is medically ready to leave but has nowhere to go occupies a bed the hospital could use for someone else, often without extra payment.
LeanTaaS is used by nearly 200 health systems across more than 1,200 hospitals, centres and clinics. Its founder and chief executive, Mohan Giridharadas, said the company wants to be the central nervous system for health systems and that the deal would let it manage patient flow from admission through to transition.
Vanderbilt University Hospital, which uses both products, welcomed the combination. Paul Moskowitz, a partner at Bain Capital Private Equity, said delayed discharges cost hospitals billions of dollars a year and that linking inpatient flow with care transition coordination could address both the extra days and the lost capacity.
The founders and the funding
Aidin was co-founded by Russ Graney and was part of the New York healthtech accelerator Blueprint Health. In 2012 it raised $600,000 from General Catalyst, HLM, Red Swan and a group of angel investors and physicians, according to TechCrunch. The company has not publicly disclosed its total funding since then.
What happens to customers
LeanTaaS said the combined product is meant to help care teams spot transition needs earlier, start the necessary work sooner and free up beds. The announcement did not describe any changes for existing Aidin hospitals or post-acute providers.
