Today we raised a $120M Series C at a $1.2B valuation, led by @MenloVentures.

We now have over $220M to become the standard for how healthcare providers transform the patient journey with AI.

As a medical student at UCSF, I watched patients fall through the cracks for reasons that had nothing to do with medicine.

Healthcare has spent decades improving clinical outcomes, yet patients were still repeating their story, navigating disconnected systems, and too often giving up before they got the care they needed.

I couldn't accept that patients spent more time on hold than with their doctors. It felt like one of the biggest unsolved problems in healthcare.

So I left to build @assort_health.

Our first chapter was learning how complex each practice's care protocols really are. It took us months to build a single agent.

That's why we built Synapse, our agentic model. It gets sharper with every edge case it sees, and with 190M+ patient interactions behind it, no one's model has seen more. That's what lets non-technical people build agents in weeks, even for the most complex workflows, with industry-leading automation rates.

This is how we grew revenue 20x in 15 months, as leading providers chose the one platform proven to handle the complexity of healthcare workflows at scale.

But this was always meant to be just the first chapter.

The first interaction isn't only where care begins. It's where patient context is created. Get that right, and every step after becomes easier.

Today we're a platform for the whole journey. Our AI agents answer calls, schedule appointments, manage referrals, complete intake, refill medications, reach patients proactively, and collect payments, all personalized to each patient.

Grateful to @jpsanday, Matt Murphy and the team at Menlo Ventures for leading, and to @lightspeedvp, @felicis, First Round Capital, Chemistry, @QuietCapital, and Joe Montana for backing us again. To the Assort team: none of this happens without your relentless focus and care. Fired up to build Healthcare that Remembers alongside you. Still Day One.

Patients are invisible in American healthcare today.

One vendor handles scheduling, another reminders, another intake, another chat. The patient repeats themselves on every channel, and staff become the integration layer, holding it all together by hand.

That carries a real cost: staff hours, patients who get missed, and appointments that never get booked.

We built Continuous Patient Conversations to run on one shared patient context, with voice, chat, two-way text, and intake all on top of it. A conversation a patient starts on your website Monday is already there when they call on Thursday. When someone comes in for a women's health visit, the system can prompt scheduling for the mammogram she's due for in the same visit.

The point isn't having one platform instead of four tools. It's that connecting them is what gets more patients scheduled, fewer slipping through, and less manual work for your team.

Most healthcare AI is reactive. It waits.

A patient calls. AI answers.

But what about the appointments that never get scheduled? The care gaps that don't get closed? The revenue that ages out because staff are too stretched to follow up?

At @assort_health, we built Activate to fix exactly that. And today, we're sharing it publicly for the first time.

Activate has already been live across primary care, orthopedics, ENT, and more. AI agents reach out to patients first via phone, SMS, and email, to book appointments, fill schedules from waitlists, reactivate patients, and collect payments.

The results from early customers, all without a single staff touch:

🔷 61% of flu shot appointments booked through proactive AI outreach at Annapolis Internal Medicine
🔷 64% referral scheduling conversion at SENTA Partners
🔷 89% of patients paid outstanding balances at Twin Cities Orthopedics
🔷 53% of appointments rescheduled automatically after a weather closure at Boston Bone & Joint

And it gets smarter over time. Every conversation, inbound or outbound, feeds what we call Patient Journey Memory. Each touchpoint gets more informed and more personal. A patient calling in with a billing question can trigger Activate to follow up on related care needs: a mammography recommendation, an open referral, a missed appointment.

Inbound AI is the foundation. Proactive outreach is what makes it transformative.

Proud of what the team built. Excited for what's next.

Three years ago I came to @AAOE_OrthoExec alone. First conference we'd ever attended. Staffed the smallest booth you've ever seen with one of our customer's daughters helping me out. A handful of people at that conference took a chance on a company nobody had heard of. I've never forgotten that.

On Monday morning I got to come back and say thank you from the AAOE main stage.

What started as voice AI for scheduling has become something much bigger, and that's largely because of our partners in orthopedics. They pulled us further into the patient journey. Intake, registration, referrals, payments, proactive outreach. We followed their lead.

I also got to moderate a panel on the future of agentic AI in orthopedics. The operators in that room were honest about what's working (patients rating AI interactions 4.3 stars, capturing dozens of appointments a week that would have been lost), what's hard (change management, physician objections), and where this is all headed. Prior auth, revenue cycle. The conversation was real and I left more energized than when I walked in.

And then there was this. Kemuel Carey from Peninsula Orthopaedic Associates, one of our earliest customers, won the AAOE Innovator Award in part for his adoption of agentic AI to improve patient access. Kemuel bet on AI before anyone else was. Watching him get recognized for that this week was a full-circle moment I didn't expect to hit as hard as it did.

25% of OrthoForum practices are now on Assort. What we built in orthopedics, we've built the same way across 22 specialties. Over 8,000 providers. If you'd told me that in 2023 I would not have believed you.

Thank you to everyone who made this week what it was. This community built us.

Being named to the Enterprise Tech 30 by @wing_vc and @NewcomerMedia alongside @OpenAI, @AnthropicAI, and @stripe is a huge honor. It’s also a reflection of something much bigger happening in healthcare.

In 2023, we learned that the hard part about patient access wasn't the voice AI. It was ingesting every unique set of rules and decisions into our system and following them with a high degree of accuracy. Every specialty, every provider, every payer, every patient scenario has its own logic. Get those nuances wrong and a patient gets routed incorrectly or doesn't get care at all. That's what we've been focused on from day one.

@assort_health is built to handle that complexity at a level others can’t, leveraging a compounding dataset of 125M+ patient interactions across 6,000 providers to continuously learn, adapt, and improve. What started as voice AI has evolved into a full AI agents platform spanning intake, scheduling, referrals, payments, and ongoing patient engagement, all connected and learning from each interaction.

The result isn't just automation. It's a system that ensures the right patient gets to the right provider at the right time, with a level of precision that actually works in the real world. With patient journey memory patients get memorable experiences, and they don't have to tell their story again or fill out another form.

Proud of the team building this, and grateful to the customers and partners helping shape it with us. We wouldn't be here without you. #ET30
