$1,000 · 6 weeks · 12 prospects
For $1,000 and 6 weeks, this proves heads of claims at mid-size auto carriers will sign dated pilot LOIs committing their written-off subrogation backlog to a third-party settlement agent.
Riskiest assumption · A head of claims at a mid-size auto carrier will commit real claims data and a dated pilot to a third-party agent that negotiates with counterparty carriers, even though the largest carriers are not on the network and industry arbitration already exists
1Focus group: who and where
VP of claims or subrogation director at a mid-size US private-passenger auto carrier ($200M-2B direct written premium), whose team closes low-dollar subrogation demands under $3,000 without pursuit every month because working them costs more than the recovery
where to find 12 · The National Association of Subrogation Professionals, whose membership is exactly this role (an association); AM Best and NAIC listings of private-passenger auto carriers ranked roughly 15-60 by direct written premium (a directory); and CLM Alliance local chapter events, which claims leaders attend for free continuing education (an event)
2Sell first, build later
A 90-day recovery pilot: Subrix pursues 200 auto subrogation demands the carrier has already closed without recovery, assembling evidence and negotiating with counterparty carriers, with the carrier's team approving any contested outcome; contingency-only, starting on a date named in the LOI
the ask · 15% of recovered dollars during the pilot, invoiced monthly, with zero fee on demands that recover nothing; per-resolved-claim pricing replaces the contingency after the pilot
a real yes · A real yes is a signed LOI with a dated Q4 2026 start, a named subrogation contact, and the 100-claim redacted extract delivered; 'send this to our innovation team', an unpaid proof of concept, or enthusiasm at a NASP happy hour is 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. Write-off backlog interviews
$300 · 14 days
Book 12 calls with subrogation directors sourced through NASP membership, CLM chapter events and warm intros. Ask the dollar threshold below which demands are closed without pursuit, the annual dollars written off, and whether a contingency-only pilot on that backlog would clear their vendor bar. Founder runs every call.
keep going if · 8 of 12 confirm a write-off threshold of $3,000 or below, and 6 of 12 state an annual write-off pool above $1,000,000
2. Redacted backlog audit
$200 · 14 days
Ask the 4 warmest carriers for a redacted extract of 100 demands closed without recovery in the last year. Founders hand-score liability strength and recoverable dollars and return a one-page findings memo per carrier. Handing over data is the commitment test; the memo quantifies the pilot's value in their own numbers.
keep going if · 2 of 4 carriers deliver the extract within 10 business days
3. Dated pilot LOI signings
$500 · 21 days
Send the audited carriers a one-page LOI, reviewed once by an insurance attorney: a 90-day pilot where Subrix pursues 200 written-off demands, the carrier pays 15% of recovered dollars and nothing otherwise, with a start date and a named subrogation contact written in. Push for signature on a live call.
keep going if · 2 of 6 carriers shown the LOI sign with a start date inside Q4 2026
4Collect a deposit up front

no cash yet: take a signed commitment
how · No cash moves before the carrier's vendor security review, which is standard at any regulated insurer, so the instrument is a signed letter of intent: the VP of claims signs a one-page LOI naming a Q4 2026 start date and a subrogation contact, and commits the redacted 100-claim extract within 10 business days of signing
what it reserves · One of the first two pilot slots, which matters because early pairs of carriers settle against each other on the network, plus the 15% contingency rate locked for 12 months
refund · Either side may cancel in writing at no cost any time before the LOI's start date
target · 2 signed LOIs with dated starts and named contacts, from 12 carrier conversations, within 6 weeks
before taking money · Pursuing claims for a carrier can fall under state adjuster licensing and debt collection rules, so have insurance counsel confirm the pilot operates under the carrier's own authority before contacting any counterparty.
Go: build it if
2 signed LOIs with Q4 2026 start dates and at least one 100-claim extract in hand within 6 weeks, on a stated write-off pool above $1,000,000 per carrier
Kill: stop if
0 signed LOIs from 12 conversations, or every carrier says it will keep routing low-dollar demands to Arbitration Forums rather than name a start date; the network never seeds, stop

outreach message
Your subrogation team closes demands under $3,000 without pursuit because working them costs more than they return, and that write-off pool runs seven figures a year at carriers your size. I'm signing two carriers for a 90-day pilot: we work 200 of those written-off demands, you pay 15% of what comes back and nothing otherwise, and your team approves anything contested. Can I get 20 minutes with you or your subrogation director this week?

deposit terms
No money changes hands at signing; the LOI commits a start date in Q4 2026, a named subrogation contact, and a redacted extract of your written-off demands within 10 business days. Either side can cancel in writing before the start date. Fees are 15% of recovered dollars, invoiced monthly across the 90-day pilot.

The idea in full
- What
- Subrix runs autonomous agents that handle subrogation - the process where one insurer recovers claim costs from another at-fault party's insurer. Each carrier connects its claims system; Subrix agents assemble evidence, assert or defend demands, and negotiate settlements with the counterparty carrier's agent on the network, with humans approving only contested outcomes. Carriers pay per resolved claim, and Subrix keeps a small ops team for carrier onboarding and arbitration escalations.
- Why now
- The current YC S26 batch alone has five AI-native insurance companies - Florin runs a carrier with zero underwriters, alongside PRINCEPS, Risklytics, Kandor and Denta - all rebuilding underwriting and distribution, while the carrier-to-carrier back office where billions move between insurers every year still runs on letters, portals and arbitration filings nobody has automated.
- Wedge: first customer and entry point
- Auto subrogation between two mid-size US carriers, sold by the founder to heads of claims, starting with the backlog of low-dollar demands both sides currently write off because pursuing them costs more than the recovery.
- Path to 100x
- Inter-carrier recoveries in US property and casualty are a $10-100B annual flow, and settlement networks are winner-take-most: every carrier that joins makes the network more valuable to every counterparty, until being off Subrix means slower, costlier recoveries. A per-claim fee on even a fifth of that flow, defended by two-sided network effects and state-by-state regulatory acceptance, is a multi-billion dollar clearinghouse - a category that does not exist today.
- Ceiling
- Existing industry arbitration bodies adding a passable AI layer would cap Subrix as a claims automation vendor rather than the settlement network.
- Closest real companies, as the generator saw them
- Florin, PRINCEPS and Risklytics are AI-native carriers that will eventually need this network rather than build it; MidLyr does risk-aware execution for financial services workflows but has no carrier-to-carrier settlement layer; Flap Insurance (graveyard 2024) tried AI insurance distribution, a different side of the industry.
- Main risk
- The largest carriers refuse to negotiate against an agent network they do not control and route everything back to industry arbitration.
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
5/5
A carrier-to-carrier settlement clearinghouse on $10-100B of annual inter-carrier flow is textbook two-sided winner-take-most with no incumbent automation.
Bootstrapper
2/5
Carrier-to-carrier claims integrations with heads of claims at regulated insurers is an 18-month enterprise sale before per-claim fees appear.
Operator
3/5
Subrogation is a genuine recurring cost heads of claims own, but settlement requires the counterparty carrier on the network before value appears.
Technologist
3/5
Carrier claims-system integrations and evidence assembly are substantial work, but the real barrier is convincing large carriers, not building the agents.
Risk
2/5
The network is worthless unless the largest carriers join, and they can refuse and route everything back to industry arbitration.
trends
2/5
Subrogation letters and portals were just as automatable in 2023; the why-now is only that five S26 carriers ignored it, and vertical agents are the most crowded cluster.
