$1,400 · 6 weeks · 30 prospects
For $1,400 and 6 weeks, prove that cloud-blocked hospital systems will commit now - with CIO signed, dated design partner LOIs - and that agent vendors will certify, before any of the three years of hardware R&D is spent.
Riskiest assumption · Mid-size hospital systems that block cloud AI today will sign a dated, CIO-approved commitment to an on-premises appliance now, rather than wait for a hyperscaler to ship a compliant inference tier.
1Focus group: who and where
CIOs, CISOs and imaging informatics directors at mid-size US hospital systems (2-10 hospitals) whose policy blocks sending patient data to cloud AI APIs and who have at least one stalled radiology or billing AI project this quarter; plus founders of vertical health agent startups stuck at deployment for the same reason.
where to find 30 · The SIIM (Society for Imaging Informatics in Medicine) community listserv where imaging informatics leaders discuss deployments; CHIME's hospital CIO membership and its Fall Forum; state hospital association member directories such as the Texas Hospital Association; plus warm introductions from YC S25 and S26 healthcare agent founders whose hospital deals are stalled on cloud data policy.
2Sell first, build later
A 2027 design partner pilot: one appliance running one certified agent in the buyer's radiology or billing department, delivered in a named 2027 quarter with pre-packaged compliance paperwork and full audit logs.
the ask · $15,000 per pilot, invoiced only after delivery and a passed security review; production price of $4,500 per appliance per month.
a real yes · A real yes is a CIO signed LOI with a dated start quarter, a named department and three named users; verbal enthusiasm, 'send us the deck' and undated interest in 2027 are not a yes.
3Small experiments
The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.
1. CIO design partner LOIs
$600 · 30 days
Build a spec one pager, an appliance render and a sample compliance packet, then pitch 15 CIOs and imaging informatics directors reached through the SIIM listserv, CHIME members and vendor warm intros. Every pitch ends with the design partner LOI: a dated 2027 quarter, a named department, three named users, and a $15,000 pilot fee invoiced only after security review.
keep going if · 6 of 15 route the LOI to legal and 3 sign it.
2. Vendor stalled deal census
$200 · 14 days
Interview 15 vertical agent founders selling into hospitals, found through the YC S25 and S26 healthcare lists and the HIMSS exhibitor directory, asking each to name a specific deal stalled on cloud data policy and to sign a one paragraph intent to certify on Ironfold. Their stalled buyers become the warm intros for the CIO pitches.
keep going if · 8 of 15 name a specific stalled deal and 6 sign the intent to certify.
3. Self serve reservation page
$600 · 21 days
Publish the buying motion the card promises: an order page with the spec, the $4,500 per month production price, 2027 pilot slots and a reservation form requiring a named department, an IT security contact and a target quarter. Send it to every contact from the first two experiments and to the SIIM listserv, and count complete submissions.
keep going if · 6 complete reservation requests arrive with named departments and security contacts.
4Collect a deposit up front
Tesla took $1,000 refundable reservations for the Model 3 and $100 for the Cybertruck before building either: the deposit is the measurement, not the revenue.

no cash yet: take a signed commitment
how · Money cannot credibly move before a hospital security review and procurement cycle, so collect no cash; collect instead a design partner LOI signed by the CIO with a dated 2027 start quarter, a named department, three named users and the $15,000 pilot fee written in and invoiced on delivery, plus a calendar-blocked security review kickoff meeting. set up: Stripe Invoicing ↗
what it reserves · One of 5 design partner slots, a named 2027 delivery quarter, the $15,000 pilot fee locked, and priority certification for the agent vendor the hospital already wants to deploy.
refund · The LOI can be withdrawn in writing at any time before delivery, and the pilot fee is only ever invoiced after the appliance passes the hospital's security review.
target · 3 signed LOIs from 15 pitched hospital systems within 6 weeks.
before taking money · Healthcare buyer: use no PHI in any demo or test, make no HIPAA compliance claims until counsel has reviewed them, and keep every pilot contingent on the hospital's own security review.
Go: build it if
3 CIO signed LOIs with dated 2027 start quarters plus 6 vendor intent to certify letters within 6 weeks, proving both sides of the network before R&D spend.
Kill: stop if
Fewer than 2 signed LOIs after 15 pitches, or 8 or more of the 15 CIOs say they would rather wait for a hyperscaler HIPAA-eligible inference tier, confirming the stated risk that a compliant cloud tier removes the reason to buy a box.

outreach message
If your radiology or billing teams want AI agents but policy blocks sending patient data to cloud APIs, you are exactly who we are designing for. Ironfold is a rack appliance that runs certified vertical agents inside your building, with full audit logs, at roughly a tenth of compliant cloud cost. We are signing 5 design partners for 2027 pilots, and no payment is due until the unit passes your security review. Would you give me 20 minutes to walk through the spec sheet and compliance packet?

The idea in full
- What
- Ironfold builds a rack appliance that hospitals, insurers and banks order online, plug into their network, and use to run vertical AI agents on premises, with audit logs and patient or financial data never leaving the building. At sustained load it collapses the compliant inference bill - today priced as cloud tokens plus compliance overhead - by roughly 10x, and agent vendors certify their products to run on the box. Hardware, certification and the vendor program take about three years of R&D before first shipments, built on contract manufacturing and a small field team rather than owned factories.
- Why now
- 745 vertical agent companies launched in the last two years, and the S26 batch alone includes Avoca Systems building an AI platform for radiology networks and Insurf building decision infrastructure for health insurance - all of them stall at deployment inside buyers who cannot send data to cloud APIs.
- Wedge: first customer and entry point
- Radiology and billing departments at mid-size US hospital systems, ordering a single appliance online with pre-packaged compliance paperwork to pilot one certified agent, no sales call required.
- Path to 100x
- Inference plus compliance spend across regulated US enterprises is a $10-100B line, and a 10x cost collapse converts it from cloud bills into appliance revenue. The compounding side is two-sided network effects: every agent vendor that certifies for the installed base makes the box more valuable to the next hospital, and every hospital makes certification mandatory for vendors - console economics where the largest installed base takes most of the market.
- Ceiling
- If frontier models stay cloud-only and keep outrunning open weights, on-prem inference stays second rate and the appliance market never converts.
- Closest real companies, as the generator saw them
- Avoca Systems and Insurf sell the agents themselves, and Zomma sells computer use agents for finance back offices; none of them sells the compliant substrate those agents need on premises.
- Main risk
- Cloud providers ship a dedicated compliant inference tier and remove the reason to buy a box.
Five judges
Each judge scores every idea in the catalog with a named rubric; the venture judge decides whether a card is shown at all (4-5 is venture-grade).
Venture investor
4/5
Console-style two-sided lock between certified agent vendors and installed hospital base is real compounding defensibility on a $10-100B compliant inference line.
Bootstrapper
1/5
Three years of hardware R&D and certification before first shipment means zero revenue for the entire window a two-person team can fund.
Operator
2/5
Three years of R&D and a vendor certification program means the whole agent industry must move before a hospital can buy anything.
Technologist
4/5
A certified rack with a vendor program is three years of real hardware and compliance engineering, though hyperscaler compliant-inference tiers could absorb it.
Risk
3/5
On-prem keeps regulated data in the building, but three years of R&D and vendor certification hinge on hyperscalers not shipping a compliant tier.
trends
2/5
The deployment stall of 745 vertical agents is real, but three years of R&D outlasts the window its own cloud-compliant-tier risk names.
