Aaron Sin
He trained to treat kids. He built software so their doctors could stop fighting their own computers.

Most founders pitch a market. Aaron Sin pitches a fraction: children are about one-third of the United States, and for decades their doctors got the leftovers of healthcare technology. That number is the spine of everything he has built since 2022, when he co-founded Develo and put himself in the CEO chair.
Develo is what he calls the first AI-native operating system for pediatrics. In plain terms, it folds the things an independent pediatric practice usually buys from three different vendors - the clinical chart, the intake forms, the billing engine - into one screen that was designed for the way a pediatrician actually works. AI scribing and automated charge capture sit inside the daily flow instead of bolted on the side.
The credentials are almost comically over-qualified for a software startup. A biomedical engineering degree from Yale. An MD from Stanford. A run at McKinsey leading projects across the healthcare value chain, then a product leadership stint at Innovaccer launching value-based care tools for accountable care organizations, health systems, and payers. He could be seeing patients. Instead he writes specs.
That choice is the whole point. Sin watched the software that pediatricians are handed and concluded it insulted the work. The fix was not another feature. It was a rebuild from the floor up, with a co-founder, Han Ke, who had spent a decade building smart EMR interfaces, most recently at Wellsheet.
Pediatricians deserve cutting-edge software that mirrors the excellence and importance of their work.
In May 2026 the thesis got its loudest endorsement yet: a $14 million Series A led by Blueprint Equity, pushing total funding to a reported $16.5 million. The platform was already running across hundreds of pediatric providers in more than two dozen states - not a deck, a deployment.
Earns a BS in Biomedical Engineering - the systems-thinking starting line.
Earns an MD, learning firsthand how clinicians actually move through a day.
Leads projects across the healthcare value chain as a consultant.
Launches value-based care products for ACOs, health systems, and payers.
Co-founds Develo with CTO Han Ke and becomes CEO.
Closes a $14M round led by Blueprint Equity; software live across 24+ states.
The 2026 round was led by Blueprint Equity, with participation from Villain Capital, Z21 Ventures, and Bienville Capital. The angel list is a quiet flex - it reads like a roll call of the EMR establishment Develo wants to replace.
Pediatrics is famously hard to build for: lower margins, family-shaped data, confidentiality rules that shift by age. Sin treated those as the spec, not the excuse.
A Stanford-trained physician and a CTO who spent a decade building smart EMR interfaces. Nobody on the founding line is learning healthcare on the job.
Sin is a father of two. The case for better pediatric software isn't only a market - it's a waiting room he has actually sat in.
Holds an MD from Stanford and an engineering degree from Yale, yet spends his days writing product specs, not prescriptions.
His investor roster includes a former Allscripts CEO and a former Cerner executive - the legacy vendors Develo aims to outpace.
Went on The Pediatric Lounge podcast to argue what modern pediatric software should look like - sponsored, fittingly, by his own company.
Develo's design philosophy starts from a family, not a single patient - a small architectural choice with big clinical consequences.
