Harbor
AI-native CRO for clinical trial operations
About Harbor
Harbor is building an AI-native contract research organization (CRO) for clinical trials. We started with an AI-native system of record for clinical trial data (electronic data capture system), grew the software business to seven trials and ~$187k in contracted software revenue over the next twelve months, then expanded into full-service trial execution and signed our first CRO contract worth $1.93M over three years. Clinical trials consume 45% of all new drug and device development spend. While some of that goes to software, sites, and patients, the largest line items are services: project management, monitoring, data management, site coordination, source verification, query resolution, record reconciliation, and analysis. Today, drug and device companies outsource clinical operations to legacy CROs and their massive teams, which is why the CRO market is $82B annually. Harbor delivers the regulated services companies buy from legacy CROs, but built around our AI-native system of record from day one. Our software already automates the core data workflows: study build, data capture, query generation, monitoring, signing, and database lock. Because we own the system of record, we can expand into the surrounding service workflows: site contracting and billing, subject engagement and retention, statistics, reporting, and more. We built Harbor because we lived through the problem. Albert spent four years in clinical trials and regulatory strategy at a medical device startup, taking an unproven wearable from first-in-human trials to FDA authorization. Nate brings the technical depth, having built scalable software at Google and Ramp and served as employee #1 at a previous YC startup.

Excited to announce I am no longer unemployed! Last June, I quit my job, emptied my apartment in San Francisco, and drove eight hours south to the suburbs of San Diego, where I moved into my friend Albert’s apartment.

I'm so very honored to announce that I've joined Harbor (YC P26) as our team's inaugural Clinical Operations Lead! Saying goodbye to my friends and colleagues at AMR Clinical after 4 (!) years has been bittersweet, to say the least. I’m incredibly grateful to the AMR Clinical team for the support and opportunities these past few years. AMR has an exceptional team of committed individuals and I look forward to celebrating your continued success for many years to come! Since I made the decision to join Harbor several weeks ago, I’ve found myself reflecting on my time at AMR and have felt an overwhelming sense of gratitude to everyone who helped shape my experience along the way. I want to give a special (though certainly not exclusive) shout out to Lisa Connery, MD, Shannon Thomas, Kari Delahunty, Nancy C., and Sean Parris. Thank you, a thousand times over, for your mentorship and investme

EDC builds are still taking 10–12 weeks. When MotilityCount ApS - SwimCountTM 'Every Day Counts' and NOVA Genomics were setting up their study, that’s exactly what they were quoted, 2-3 months just to get the system live. So, we did it in 9 days. Fully validated. One flat fee....

10y ago today, my high school principal suspended me for making an app that let my classmates see who was in their classes before school started Every day I think about what life would've been like if I'd turned it into a GPT wrapper and raised 5 at 50 She still mogs me on base
