Build @ Deerfield, powered by Out-of-Pocket
January 20-21, 2027
New York City

There’s never been a better time to build something new in healthcare. And we want to see your ideas come to life.

Build @ Deerfield, powered by Out-of-Pocket, is a five-week healthcare and life sciences AI hackathon for small teams. In December, selected teams will receive a $10,000 non-dilutive grant, mentorship, and tools to help them bring their ideas to life.

It all ends in a reception in New York City on January 20-21, 2027, with workshops, pitches, and judging for the chance to win $120K more in grants across 1st, 2nd, and 3rd place-winning teams.

Let’s see you pull the future forward (or at least move us past fax machines).

Request for Startups

A few areas we’re particularly interested in. It is ok if your idea doesn’t fit neatly within one of the areas below. If it involves AI + healthcare or life sciences, we want to hear from you!

Biosecurity

Biological capability is now being generated faster than anyone can verify its safety. AI agents are outperforming PhD-level virologists on technical laboratory questions in the virologists' own subfields. Sequence-based screening and customer verification, the cornerstones of biosecurity since 2009, are no longer sufficient as standalone safeguards against AI-assisted design, especially given unclear liability across the design-synthesis-use pathway.

The stack is surprisingly brittle. Agents can plan and execute multi-step design workflows while concealing their work from trace-based monitoring, poisoned data can do meaningful damage at as little as 1% of inputs, and red-teaming results go stale the moment a new model is released.

We're looking for teams to build the verification and containment layer for this world. The question is not whether AI creates biological risk, but how to deliver guarantees that are auditable, testable, and durable as capability keeps compounding.

Apply Now

Robotics and Movement

While AI is reshaping healthcare delivery, one frontier remains underexplored: the physical work of caring for patients and meaningfully improving their quality of life, especially when it comes to movement.

We're looking for teams to build robots, wearables, and prosthetics, along with the intelligence behind them, that operate in the physical world of hospitals, homes, and rehab settings. Areas of interest include, but aren't limited to, perioperative automation, assistive mobility, neuromodulation, patient-facing robot design, and simulation environments.

Above all, we want embodiment: systems that sense, move, and respond continuously alongside patients and clinicians, rather than sitting in a chat window. Many past solutions were held back by hardware constraints and poor economics, so show us why now is different.

Apply Now

AI for Rare Pediatric Disease and Drug Discovery

We are interested in how modern agentic workflows can supercharge drug discovery, especially approaches that are mindful of the current limitations of AI in this field. We suspect that the most promising approaches will involve tightening information loops: a new paper in one field triggers drug discovery signals in another; expanded datasets improve agentic drug repurposing; and precision therapeutics allow for drugs tailored to a patient’s entire disease profile, rather than a single pathway or mutation.

We think rare pediatric diseases are a particularly promising use-case, with multiple low-hanging fruit, opportunities for long-term impact, and regulatory incentives like Priority Review Vouchers (PRVs) to reward successful development.

We are also interested in workflows that use agents to enhance the patient journey, such as ambient scribes/agents tailored to an individual’s rare disease that help patients and their families understand a diagnosis or navigate the clinical trial landscape.

Apply Now

Longevity and Biomedical Evidence Evaluation

As interest grows in longevity innovations, we need AI that can help make sense of it all.  We see a critical need for AI systems that translate how a careful scientist reads a paper into rubrics a machine can run. These rubrics would cover study design, trust tiers, sponsor independence, aggregation of conflicting evidence, and safety checks against federal sources.

Systems like these could help patients and providers turn everyday questions about supplements, diagnostics, and longevity interventions into honest, traceable answers grounded in the scientific literature.

We also see this as a strong starting point for improving healthcare AI evaluations more broadly.

Apply Now

Private Data, Data Exhaust, and Data Sharing

By training on the sea of publicly available health data, LLMs have turned loosely structured knowledge into coordinated intelligence.

The next generation of agents will need more private data: patient records, internal company data (such as hospital system utilization), or data at the edge from phones and logging systems. Getting there will take a combination of skills, including navigating regulations on protected health information (PHI), extracting insights in place from firewalled systems, and bootstrapping statistically grounded synthetic datasets.

Private data is the next frontier, and for teams willing to tackle the thorniest problems, the bigger the mess, the larger the moat. We're interested in new ways to source complementary datasets that expand the alternative data market, as well as tools that help companies unlock more of their own data safely and compliantly.

Frequently Asked Questions

Do I need to have something built already?

No. Teams can apply with an early idea. The application asks what exists today so we can understand the starting point, not punish teams for starting from zero.

Can I apply alone?

No. Teams must have 2-6 people.

Do I need to be in New York to participate?

No, but every listed team member must attend in person in New York City on January 20-21, 2027. And we think you’ll benefit the most if you build your company here.

What does each selected team receive?

Each selected team receives a $10,000 non-dilutive grant, five weeks to build, virtual office hours and mentorship, and help getting the data, tools, or access that could unblock the work. Final grant-use terms will be included in the participation agreement.

Is travel to NY covered?

Travel and stay will not be included if you are applying outside of the New York area.

What can we use the grant for?

The grant is there to help you build. You can use it for any reasonable expense that directly moves your project forward during the program. 

Do we give up equity?

No.

What are you looking for in a team’s application?

We are looking for:

  • Clarity of thought around the problem, the solution, and the process of getting from point A to B. This doesn’t need to be the final product, but we want to understand your thinking behind it. Hint: Don’t let AI write this -- we want to hear from you.
  • Originality: We love seeing projects that take unique approaches or tackle areas others are not looking at.
  • Hustle: We want to see the work you’ve already put in and what you can do in a short period of time.
  • That you care. Is this a problem you are passionate about? Are you serious enough about this idea that you would pursue it? Is this hackathon something you’d invest time into to get the most out of it?

Can an existing company apply?

Yes, if it is early-stage and has less than $3 million in annual recurring revenue.

When are applications due?

Applications close November 19, 2026.
