ScanSlot

Idea

ScanSlot turns a fax-and-phone imaging referral into a booked scan in under two minutes. It gives independent, freestanding imaging centers one no-login link that shows a referring office real-time open slots, plus AI intake that turns an inbound faxed or emailed order straight into that scheduling queue. Small imaging centers stop losing patients to whichever competitor answers the phone first.

Market gap

Imaging is the easiest referral to redirect. A referring office doesn't think of it as disloyalty, it just books wherever a slot opens first, and today that decision is made over fax and phone. A 2023 Journal of Digital Imaging study found 7% of radiology orders are never scheduled at all, and identified the friction: patients and staff struggling to find contact information, navigating phone trees, and reaching a scheduler during business hours (see Sources). Faxed orders fare worse: industry data puts faxed-referral-to-scheduled-appointment conversion at roughly half.

The gap is sharpest at small, independent centers. There are about 6,900 diagnostic imaging facilities in the US doing $26 billion in revenue, and the market is genuinely fragmented: the largest chains capture under 20% of it (Yahoo Finance industry report, in Sources). That means thousands of facilities are single-site or small multi-site operators. Those are also the practices hit hardest by staffing gaps: the ACR/RBMA workforce survey found 67% of radiologists in private practice report being understaffed, against 47% in hospital-based practices (AuntMinnie, in Sources). Fewer staff to chase a fax queue means more referrals fall through.

Timing is right now because the capital and attention in this space is flowing to the opposite end of the market. Tennr just raised a $101M Series C at a $605M valuation to automate referral intake, explicitly because "more than one-third of Americans" get a referral each year and it still arrives by fax (PRNewswire, in Sources). That's a strong signal the underlying problem is real and big. But Tennr, Kyruus, and ReferralMD sell to large specialty groups and health systems, at enterprise contract sizes. None of them are built, priced, or sold for a single-site or 2-to-5-location imaging center that just wants to stop losing patients to the center down the street.

Total Addressable Market (TAM)

Bottom-up:

• US diagnostic imaging facilities: ~6,900 (Yahoo Finance/IBISWorld-sourced industry report, in Sources).
• The top 10 operators run 1,100+ of those centers (same report), and large hospital-system-owned imaging departments typically already run on an enterprise EHR/RIS with built-in scheduling (Epic Cadence, Kyruus). Assumption: independent, freestanding, non-top-10-chain imaging centers make up roughly 5,000 of the 6,900 facilities. This is my own estimate built on the fragmentation stat above (top orgs under 20% share), not a directly published count, and it is the single biggest assumption in this math.
• Of those, assume roughly 70% (3,500 facilities) are physician-owned/independent rather than hospital-outpatient-department-owned, since hospital-owned imaging typically already has referral tooling bundled into its EHR. This is also my own estimate, not a cited figure.
• Blended annual contract value per location, averaging the Starter and Growth tiers below: ~$4,500/year.

TAM = 5,000 facilities x $4,500 = $22.5M SAM (independent, non-top-10-chain, physician-owned facilities) = 3,500 x $4,500 = $15.75M SOM (3-year target, 5% of SAM) = 175 locations x $4,500 = ~$788,000 ARR

Monetization strategy

Flat monthly SaaS subscription per location, billed to the imaging center. The center pays because a captured referral is direct revenue (one lost MRI referral is worth hundreds of dollars in technical and professional fees), so the tool pays for itself on the first save each month. Customers keep paying because the referral-source leaderboard becomes an operational habit: front-desk and outreach staff check it to see which referring offices are drifting away, and use it to prioritize physician-liaison visits.

Pricing strategy

• Starter, $249/month per location (entry point): AI fax/email referral intake, one shareable booking link, automated confirmation nudges, single-location dashboard.
• Growth, $499/month per location (anchor): everything in Starter, plus unscheduled-referral follow-up automation, the referral-source leaderboard, a multi-location roll-up dashboard (up to 5 locations), and CSV slot-sync for centers that want to feed in RIS availability without a live integration.
• Network (roadmap, not MVP): custom pricing for 6+ location groups and hospital-affiliated networks that want deeper RIS integration. Explicitly not built in the MVP: that's Tennr/Kyruus territory.

Lead magnet

A free, no-signup "Referral Leakage Calculator" web page: a center manager enters their monthly referral volume and their rough guess at what share goes unscheduled, and gets back an estimated dollar figure lost per month and per year, benchmarked against the published 7% unscheduled-order rate. It proves the value math in 30 seconds and ends with a book-a-demo button.

Competitors

• Tennr: AI orchestration platform automating referral-based care intake (imaging, DME, specialty). $605M valuation, serves "hundreds of providers" at enterprise scale, not priced or packaged for a single-site imaging center.
• Kyruus Health: enterprise care-access and referral platform for large health systems. Custom pricing commonly cited at $500K+ annually, far outside a small center's budget.
• ReferralMD: mid-market referral management aimed at multi-specialty medical groups; independent industry comparisons note it's oversized in scope and price for smaller practices.
• Curogram, Dialog Health, Luma Health, Solutionreach, Weave: patient-communication and no-show-reduction platforms used broadly across small medical practices, including some imaging centers. Dialog Health tags outbound messages by referral source, but none of them give the referring office a live, no-login slot-booking view for that specific center.
• eFax Clarity / Documo: AI-powered fax parsing and cloud fax. Solves the "read the incoming document" problem but stops there; it doesn't manage scheduling or give referring offices any visibility into open slots.

What competitors offer now

Tennr and Kyruus both do real, sophisticated document-to-workflow automation, but they're sold as platform deals to large health systems and multi-site specialty groups, with implementation timelines and contract sizes that assume an IT and revenue-cycle team on the customer side. Patient-texting tools (Curogram, Luma Health, Dialog Health, Solutionreach, Weave) are built to talk to the patient after a referral already exists: appointment reminders, prep instructions, no-show reduction. None of them solve the moment before that, when a referring office's front desk is deciding, right now, which imaging center to call. Fax-and-document tools (eFax, Documo) digitize the paperwork but leave scheduling exactly as manual as before.

What can be done differently to attract customers

Sell directly to the single-site and small multi-site operator that every enterprise platform ignores. Setup takes a day, not a quarter: no RIS/EHR integration is required to start, slots can be entered or CSV-synced by center staff. Price on a credit card per location, not a multi-year enterprise contract. And make the referral-source leaderboard the retention hook: it turns "which practices are drifting away" from a guess into a weekly, actionable list a center's own outreach or physician-liaison staff can work.
