When Dr. Zhen Chan finished his training in pediatrics, he had learned how to diagnose rare blood cancers in children, navigate treatment protocols, and hold space for families in some of the hardest moments of their lives. What he hadn’t learned (read: what no one had taught him) was how to read an explanation of benefits, negotiate a payer contract, or make sense of the billing codes that governed whether a patient’s care would actually be covered.

His experience demonstrated an enormous gap between what medical school teaches you and what practicing medicine actually requires. That gap–and the quiet, compounding pressure it puts on physicians–became the seed of Grapevyne.

What the Data Doesn’t Capture

Before Grapevyne became what it is today, there was a different hypothesis. 

Healthworx Studio had identified a real and measurable problem in physical labor markets: hospitals hemorrhaging budgets on locum tenens agencies, critical roles in rural and specialty practices going unfilled for months, and a recruitment process that treated physicians like resumes rather than human beings with lives, families, and preferences. The unit economics were striking: locum agencies were bringing in tens to hundreds-of-thousands of dollars per temporary placement. These inefficiencies felt solvable.

This predicament made a lot of sense on paper–clear demand, obvious market failure, and a real opportunity to build something better. However, ideas modeled in spreadsheets can play out very differently when they enter the unforgiving arena of human behavior. 

What the Studio team discovered, and what Zhen confirmed from his own years practicing medicine, is that physicians don’t make career decisions the way hiring models assume they do. They don’t respond to financial incentives in a vacuum. They ask their colleagues, they trust their peers, they want to know what a town actually feels like before they uproot their lives to move there. A thorough job posting could try and give doctors that first-hand preview, but it could never play the role of a trusted colleague who really “gets it.” 

A byproduct of this discovery, while not any less meaningful, was the realization that doctors are people, too. As such, maybe this model needed to evolve beyond a job board or a recruiting tool into a place where doctors could put down their professional armor and be something they rarely get to be in the course of their training and careers: humans.

A Recruitment Tool Turns Community Platform

Grapevyne’s early version was slightly more transactional: a peer referral network designed to route physician job opportunities through trusted relationships rather than impersonal agencies. The goal was to cut out the expensive middleman and reward physicians for connecting their colleagues to promising opportunities. In other words, reward and organize behavior that was already happening within physician communities.

Zhen kept running into a repetitive impasse. The jobs that surfaced through the platform, often rural postings or lower-paying roles in underserved areas, weren’t what most physicians were looking for long-term. What’s more, the recruitment frame itself was a liability–physicians tend to be deeply skeptical of anyone who seems to want something from them. A platform built around jobs struggled to break that barrier of suspicion, however well-intended.

So in 2025, Zhen made a deliberate decision to stop chasing placements and start building something physicians actually want to be a part of.

The current version of Grapevyne is a free, community-first platform. Membership is open to physicians, nurse practitioners, and physician assistants. Revenue comes from sponsorships and affiliate relationships rather than from members themselves. Programming centers around original webinar series: Doctors on Doctors, which facilitates peer-to-peer conversations, and High Yield, which focuses on practical knowledge gaps such as revenue cycle management, insurance navigation, and the real-world mechanics of practicing medicine.

There’s also Med School 1.5, an initiative Zhen launched directly in response to what he kept hearing from members: that the foundational knowledge required to actually practice medicine sustainably (billing, coding, insurance) simply wasn’t part of their education or training. This program curates accessible resources for physicians who didn’t learn this in school and don’t have time to figure it out independently. Resources that also directly affect patient outcomes and physician sustainability.

The Strength of Community

Grapevyne currently has around 400 members. According to growth-focused venture culture, that’s a modest number, but from an insider’s perspective, it’s exactly the right one. In Zhen’s words, he’d rather have 400 people who get real value from this platform than 4,000 who sign up once and never return.

The platform has grown almost entirely from word of mouth, which Zhen sees as a signal rather than a limitation. Physicians are not early adopters as a professional culture. They are deliberate, skeptical, and protective of their time. When one physician tells another that something is worth joining, that means something.

While Grapevyne continues to demonstrate quantitative growth through membership and engagement, it’s the qualitative measures that showcase its true impact. A pediatrician recently found a position through Grapevyne–not just a job, but the right job–in Los Angeles where she’d always wanted to live. Seven months later she is still there and thriving; not solely in her career, but her life outside of the practice as well. 

Success in business will likely always hinge on financial outcomes, but in this particular model, success takes on a greater, more qualitative meaning. Zhen has managed to build and nourish a supportive community for doctors in a way that’s been lacking for this population. He has delivered as a founder in his ability to zoom in on an underserved need that has long been overlooked or ignored in the marketplace, leaning on his education, experience, and empathetic nature to design a new and impactful solution.

A Doctor Turned Founder

Zhen’s path to Grapevyne wound through a few different worlds. He trained in pediatrics, but frustration with healthcare’s systemic shortcomings sent him looking for a new path. He sought out opportunities that added consulting and venture capital to his toolkit, exploring his interests in entrepreneurship. He wanted to understand how the industry worked from the outside while extending his impact in the broader healthcare landscape. 

What he found time and time again was a healthcare system that talked about physician well-being but didn’t practice it. The system trained and recruited doctors aggressively and then left them largely on their own to navigate the business side of medicine, the burnout, and the resulting isolation. Fax machines were still the standard and peer connection beyond one’s graduating class was mostly informal and often accidental. The knowledge that could help a physician build a sustainable, satisfying career–how insurance actually works, how to evaluate a contract, what life might be like in a certain community–wasn’t being passed down in any thoughtful, organized way.

Healthworx Studio as Steward

Studio’s approach to Grapevyne has evolved alongside the company’s own evolution. Early on, the team was more hands-on, helping to validate the market problem and structure the initial investment thesis. As Zhen stepped into his own as a founder, the relationship shifted.

For a company like Grapevyne, with a founder who’s executing, the job of Healthworx Studio is to show up when it matters. That means connecting Zhen to expertise and networks when they’re needed, having check-ins rather than intense oversight, and trusting that the model–even one that has deliberately slowed down monetization in favor of community trust–is making the right bets long-term. 

What the Studio has also come to appreciate is how much the Grapevyne story reflects something larger about what’s broken in healthcare talent markets. What was originally thought to be an operational problem turned out to be fundamentally cultural. Physicians need to see themselves as a community before they’ll trust a platform. There’s no shortcut to that.

The Peace Within the Platform

Somewhere in the conversation between a venture studio trying to solve physician labor market inefficiencies and a pediatrician who was tired of watching colleagues burn out alone, a different kind of company emerged. Not one that solely routes physicians to jobs, but one that helps them show up for each other.

The premise at the heart of Grapevyne is deceptively simple–doctors are human beings. They need mentorship and connection and community. They need practical knowledge that their education didn’t provide. And most importantly, they need to be seen, not just placed. In order to do so, there must be consideration around the varying interests doctors might have outside of the day-to-day clinical work itself. 

Grapevyne evolved to provide that space for conversation and knowledge sharing. It turns out that this premise is both a product strategy and a business. And maybe, for the physicians who find their way into Grapevyne’s rooms–virtual or otherwise–something closer to a lifeline.
