Handover Health

Agents that complete patient handoffs between independent practices, worldwide.

Handover gives every small practice - dental, physio, dermatology, private GP - an AI agent that manages the outbound and inbound side of referrals: it books the specialist slot, transfers the relevant records, chases the result, and closes the loop with the referring clinician.

$500 · 4 weeks · 25 prospects

For $500 in 4 weeks, prove that a dental practice will prepay $299 for referral handoffs when only its own oral surgeon joins - the pair-by-pair answer to the cold start.

Riskiest assumption · A dental practice owner will pay before any network exists, because the value lands pair by pair: their money moves when only the one oral surgeon they already refer to comes aboard with them.

1Focus group: who and where

Office manager or owner-dentist of a 2-8 chair general dental practice in the Phoenix metro that sends 8 or more oral surgery referrals a month (extractions, implants, wisdom teeth) and whose front desk still moves records by fax and chases outcomes by phone.

where to find 25 · Dentaltown front-office and referral discussion boards, the Nifty Thrifty Dentists Facebook group, the Arizona State Board of Dental Examiners public license list filtered to Phoenix general dentists, and the AADOM (American Association of Dental Office Management) Phoenix-area chapter meetings.

2Sell first, build later

A founding pilot for 10 Phoenix practice pairs: Handover runs every oral surgery referral end to end - slot booked, records moved, report chased, loop closed - starting within 45 days of payment, with the practice's named surgeon onboarded free.

the ask · $299 per month per sending practice, locked for 12 months for founding members (planned list price $499)

a real yes · A real yes is a $299 first-month payment received plus the counterpart surgery office's signed pilot agreement with a start date; compliments, unpaid trials, and 'send me info after you launch' are noes.

3Small experiments

The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.

1. Paired pilot pre-sale calls
$150 · 14 days
Book 15 twenty-minute calls with office managers recruited through Dentaltown DMs, the Nifty Thrifty group, and the AADOM chapter. Map their monthly oral surgery referral volume and hours spent chasing, then pitch the founding pilot: $299 a month, first month prepaid by invoice, and we onboard the oral surgery office they name, free on the receiving side. The ask on every call is the prepayment plus a warm intro to their top surgeon.
keep going if · 4 of 15 practices prepay $299 and make the intro to their named oral surgery office
2. Surgeon-side sign-up test
$100 · 10 days
Call the referral coordinator at each oral surgery office the paying dentists named. Offer free founding membership on the receiving side for cohort 1 and ask them to sign a one-page pilot agreement with a start date. This tests whether the receiving side of the pair joins when the sending side has already paid.
keep going if · 5 of 8 named surgery offices sign the pilot agreement with a dated start
3. Manual handoff dry run
$250 · 10 days
For the first paid pair, a founder personally runs 5 live referrals as the agent: books the specialist slot, moves records through the practices' existing HIPAA-compliant channels under signed BAAs, chases the surgical report, and closes the loop with the referring dentist. Measure cycle time against the practices' own three-week baseline.
keep going if · 5 of 5 referrals close the loop in under 5 business days and both offices confirm month 2 at $299

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.

$299

per prospect, refundable

how · First month prepaid by invoice from the sending dental practice - the natural instrument for a small business buying a monthly service, and it forces the budget conversation the cold-start theory says never happens. The office manager or owner-dentist signs a one-page pilot agreement; the receiving surgery office signs its own free founding agreement. set up: Stripe Invoicing ↗

what it reserves · One of 10 founding-pair slots in the Phoenix metro, the $299 monthly rate locked for 12 months, and free onboarding of their named oral surgery office

refund · Refunded in full within 5 business days if the paired pilot is not live within 45 days or if the practice cancels before go-live.

target · 4 prepaid pairs from 15 pitched practices within 28 days

before taking money · Patient records are PHI: sign a BAA with each pilot practice and move records only through the practices' existing HIPAA-compliant channels before touching a single live referral.

Go: build it if

4 or more practices prepaid $299 with counterpart intros, 5 of 8 surgery offices signed with start dates, and 5 of 5 manual handoffs closed in under 5 business days - build the agent.

Kill: stop if

Fewer than 2 prepayments from 15 pitched practices, or fewer than 3 named surgery offices willing to sign even at free - the pair-by-pair wedge does not beat the cold start; stop.

5 Scripts to run itoutreach message, landing copy, deposit terms · click to open

outreach message

Your front desk probably spends hours a week faxing records to the oral surgeon and calling to find out whether the patient ever showed up. I'm building Handover Health: we take over your oral surgery referrals end to end - booking the slot, moving the records, chasing the report back - and we onboard your surgeon's office with you, free on their side, so the loop actually closes. Founding price is $299 a month for the first 10 Phoenix practices. Can I get 20 minutes with you this week?

landing page

Your oral surgery referrals booked, tracked, and closed - no more fax chase $299 per month, first month prepaid and refundable, covers every oral surgery referral you send; your surgeon's office is onboarded free Prepay your first month to reserve one of 10 founding pairs in Phoenix

deposit terms

Your $299 first-month payment reserves one of 10 founding practice slots in the Phoenix metro and locks your rate at $299 per month for 12 months. Service starts within 45 days, once the oral surgery office you name is onboarded. If we miss that date, or you cancel before go-live, we refund the full $299 within 5 business days.

The idea in full

What: Handover gives every small practice - dental, physio, dermatology, private GP - an AI agent that manages the outbound and inbound side of referrals: it books the specialist slot, transfers the relevant records, chases the result, and closes the loop with the referring clinician. Agents negotiate directly with counterpart agents at other member practices, so a handoff that today takes faxes and three weeks completes in minutes. Practices pay a monthly subscription per location; the product is built on integrations with existing practice-management systems, not new clinical tech.
Why now: Five companies in the last two years pitch an 'operating system' for care - EnhancedDx alone claims 'The Specialty Operating System For Complex Patient Journeys' - and all of them organize one practice at a time. The journeys EnhancedDx describes break between practices, and no one owns the handoff itself, which is a coordination problem, not an OS problem.
Wedge: first customer and entry point: Dental-to-oral-surgery referrals in one metro, distributed through the two practice-management vendors those practices already use, which gets both sides of each handoff onto the network at once.
Path to 100x: Administrative coordination between outpatient practices consumes tens of billions of dollars in staff time globally, and referrals are the single densest thread of it. The company that becomes the handoff protocol wins most of the market, because each practice that joins makes membership more valuable for every practice it refers to - a compounding two-sided network no feature-copying incumbent can shortcut - and private-pay specialties let the same product run in every country from day one.
Ceiling: If the big practice-management incumbents bundle a passable referral feature before the network reaches density, Handover stays a niche connector in a few specialties.
Closest real companies, as the generator saw them: EnhancedDx organizes complex journeys inside a specialty practice rather than between practices; Usawa Care connects families to a pediatrician, a patient-to-doctor match, not a practice-to-practice protocol; Daleela is a consumer health assistant.
Main risk: Referral behavior is habitual and local, and practices refuse to pay until enough counterparties have joined - the cold-start kills it metro by metro.

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
Capital-light software margins on a global two-sided referral protocol, with practice-management vendors delivering both sides of each handoff at once.
Bootstrapper
5/5
Capital-light integrations on existing practice-management systems, per-location subscription from practices already paying staff to chase faxed referrals.
Operator
3/5
Referral admin burns staff time daily in every practice, but habitual local referral behavior means nobody pays until counterparties join.
Technologist
2/5
Agents riding two practice-management vendors' APIs is exactly the referral feature those incumbents bundle in one release, as the ceiling concedes.
Risk
2/5
Distribution runs through the two practice-management vendors the card admits could bundle a passable referral feature and end the network.
trends
2/5
Referral faxes were just as broken in 2023; the why-now is whitespace between 'operating system' pitches, and metro-by-metro cold start outlasts any window.
