Subroclaim

Agents that negotiate insurer-to-insurer claim recoveries on both sides of the file.

Subroclaim runs subrogation and inter-carrier recovery as an agent service for US property and casualty insurers: the agent reads the loss file, builds the demand with liability evidence, and then negotiates directly with the other carrier's Subroclaim agent, escalating to a human adjuster only on disputed liability or amounts above a set threshold.

Test it before you build it

$2,600 · 6 weeks · 20 prospects

For under $2,600 and six weeks, prove that two regional auto carriers will each pay a deposit-backed pilot fee to run one subrogation lane between them through an agent, before the agent exists.

1Focus group: who and where

Subrogation directors and VPs of claims at US regional auto carriers writing $100M to $2B in premium, whose teams file and answer thousands of inter-carrier demands a year through Arbitration Forums and are measured on recovery rate and cycle time this quarter

where to find 20 · The National Association of Subrogation Professionals (NASP) member directory and its annual conference; Arbitration Forums member company lists, which are public; LinkedIn Sales Navigator filtered on title 'subrogation' plus 'director' or 'manager' at US property and casualty carriers with 200 to 5,000 employees; the Claims and Litigation Management Alliance (CLM) member roster

2Sell first, build later

A 90-day matched-pair pilot sold before the agent is built: one subrogation lane between two named carriers, all demands under a $5,000 threshold prepared and negotiated by Subroclaim with the concierge team behind the interface, human sign-off on every settlement, starting within 45 days, success defined as cycle time cut by 40 percent on the lane with recovery rate held flat

the ask · $4,500 per carrier per pilot, invoiced up front, then $2,000 per carrier per month plus 4 percent of net recoveries at conversion

a real yes · A real yes is both carriers in a pair paying the pilot invoice and signing the lane definition with a start date and named adjusters. Not a yes: one-sided interest, an innovation team workshop, an unpaid proof of concept, or a request to present to the consortium committee

3Small experiments

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

1. Cycle-time teardown calls
$300 · 18 days
Book 15 calls with subrogation directors using NASP and LinkedIn outreach. Script each call to extract three numbers from their own operation: demands sent per month to their top counterparty carrier, average days from demand to settlement, and the dollar threshold below which adjusters settle without escalation. End by asking which single counterparty lane they would automate first.
keep going if · 9 of 15 directors share their numbers and name a specific counterparty carrier lane
2. Concierge demand package
$700 · 14 days
Take 10 closed, redacted auto subrogation files volunteered by one engaged carrier, and hand-build the demand package for each - liability evidence, damages summary, negotiation range - behind a simple portal, delivered in 48 hours per file. Compare the hand-built range against what the file actually settled for.
keep going if · 8 of 10 hand-built demands land within 10 percent of the actual settled amount, and the director says they would have sent them as-is
3. Matched-pair pilot offer
$300 · 21 days
Identify pairs of carriers from the calls that name each other as a top counterparty, and mail both a one-page pilot offer: one lane of demands under a $5,000 settlement threshold run through Subroclaim for 90 days, with humans approving every settlement above the threshold. A founder brokers a three-way scoping call per pair.
keep going if · 2 matched pairs hold the three-way scoping call and 1 pair agrees on a lane definition and threshold in writing
4. Fake-door ROI calculator
$150 · 10 days
Publish a one-page calculator that takes demands per month, average recovery and cycle days and outputs dollars trapped in the queue, with a 'reserve a pilot lane' button as the fake door. Promote it only through direct email to the 20 prospects and a NASP LinkedIn group post.
keep going if · 6 of 20 prospects run the calculator with real numbers and 3 click reserve

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.

$2,500

per prospect, refundable

how · A paid design-partner pilot invoiced up front: each carrier in the matched pair signs a 90-day pilot order form with the lane definition and settlement threshold attached, and pays a $2,500 deposit against the $4,500 pilot fee by ACH on signature, with the balance due at go-live set up: Stripe Invoicing ↗

what it reserves · The first pilot lane slot, the counterparty seat locked so their named counterpart cannot pair with another carrier first, the concierge settlements team for the quarter, and their state's arbitration filing handling included

refund · The deposit is refunded in full if the pilot has not gone live within 60 days of signature or if the paired carrier withdraws before start

target · 2 paid deposits (one matched pair, $5,000 collected) within 42 days of the first call

Go: build it if

One matched pair with both deposits paid and a dated start, plus 8 of 10 concierge demands within 10 percent of actual settlements and a third carrier asking to join the lane

Kill: stop if

After 15 calls no two carriers that name each other will sit on a scoping call together, or legal at both engaged carriers refuses any settlement authority under any threshold, or fewer than half of concierge demands are usable

The idea in full

What: Subroclaim runs subrogation and inter-carrier recovery as an agent service for US property and casualty insurers: the agent reads the loss file, builds the demand with liability evidence, and then negotiates directly with the other carrier's Subroclaim agent, escalating to a human adjuster only on disputed liability or amounts above a set threshold. Carriers pay a fee per resolved recovery plus a platform subscription. Subroclaim keeps a small settlements operations team for arbitration filings and state-specific exceptions, so a carrier can go live without changing its claims system.
Why now: YC's Fall 2026 Request for Startups mapped to this cluster is Multiplayer AI, and this is the version of it that has money on both sides; Patchwork, an AI powered team communication tool, died in 2024, which shows agent-to-agent value inside one company is thin while inter-company negotiation carries a settlement cheque.
Wedge: first customer and entry point: Two regional auto carriers that already exchange thousands of subrogation demands with each other: run that single lane end to end, then use the cycle-time drop to recruit the third carrier.
Path to 100x: US claims administration and recovery operations is a $10-100B cost line, and the network is literal: each carrier that joins makes automated resolution available to every carrier already on the platform, so the second-place network settles a shrinking share of files. Regulatory approval per state plus carrier-side authority limits create a slow, defensible category that resembles a clearing house more than a software vendor.
Ceiling: The top ten carriers write most of the volume, so if three of them build a shared consortium utility instead, Subroclaim is left with regional carriers and a sub-$1B outcome.
Closest real companies, as the generator saw them: Patchwork tried agent-mediated communication inside one team and is in the graveyard; Dock's multiplayer agent workspace and Gini's Slack coworker stay inside company walls. Subroclaim's agent only creates value when the counterparty is a different regulated company.
Main risk: Carriers refuse to let an outside agent bind settlement authority, keeping every negotiation human on at least one side and erasing the speed advantage.

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
A literal clearing-house network where each carrier joining makes every other carrier's files settleable, paid per recovery out of a $10-100B cost line.
Bootstrapper
2/5
Carriers must grant an outside agent settlement authority state by state, and a settlements ops team burns cash while they decide.
Operator
4/5
Subrogation recovery is a $10-100B cost line carriers already staff, and fee per resolved recovery matches money they pay adjusters today.
Technologist
3/5
Agent-to-agent subrogation negotiation is mostly LLM plus a settlements ops team; the defensibility is carrier network density, not engineering depth.
Risk
2/5
Value needs the counterparty carrier on the platform, and three of the top ten carriers building a consortium utility ends it.
trends
3/5
Agent-to-agent negotiation with a settlement cheque attached is the paying version of the Multiplayer AI RFS, though state-by-state carrier approval was equally slow in 2023.
