Flagline

Shared fraud and AML signal network for community banks and credit unions.

Flagline is a subscription screening layer that plugs into a community financial institution's core-system exports through no-code connectors, checks every new account and transaction against a live watchlist pooled from all member institutions, and produces SAR-ready case files.

Test it before you build it

$1,250 · 5 weeks · 20 prospects

For $1,250 in 5 weeks, prove that five Texas community banks will each pay a $1,000 deposit and contribute confirmed fraud signals to a pooled watchlist run by a startup.

Riskiest assumption · A BSA officer at a Texas community bank will pay $500 a month and route their bank's confirmed fraud signals into a startup-run shared pool, replacing the free peer email thread, before the network has any scale

1Focus group: who and where

The BSA officer at a Texas community bank or credit union with $200M-2B in assets who ate a check-fraud or mule-account loss in the last 12 months and currently warns peer banks through an informal email thread

where to find 20 · Independent Bankers Association of Texas member directory and its compliance events; FDIC BankFind Suite filtered to Texas banks under $2B to build the call list; the BankersOnline BSA/AML forum where these officers already ask each other about fraud rings; Texas Bankers Association BSA/AML school attendee network

2Sell first, build later

Founding membership in the Texas pooled fraud watchlist: your confirmed signals screen every member's new accounts and transactions, SAR-ready case files included, connector live within 90 days of signing, five institutions in the first cohort

the ask · $500 per month per institution, locked for two years for the founding five

a real yes · A real yes is a signed founding agreement plus the $1,000 deposit paid by the institution; a BSA officer's enthusiasm, a request for a demo, or an unpaid promise to join once others do does not count

3Small experiments

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

1. Fifteen BSA officer commitment calls
$250 · 10 days
Build a list of 40 Texas institutions from FDIC BankFind and the IBAT directory, email BSA officers directly, and book 15 twenty-minute calls. On each call, ask for their last three fraud losses, whether a pooled watchlist from five named peer banks would have caught them, and whether their institution is registered under Section 314(b) so it can legally share. End every call by asking them to review the founding member offer.
keep going if · 8 of 15 officers name a specific loss the pool would have caught and agree to review the founding member offer; at least 10 of 15 are 314(b) registered or willing to register
2. Manual pooled watchlist digest
$300 · 14 days
Before any code, run the network by hand for two weeks with 5 banks from Experiment 1: each submits confirmed fraud and mule-account signals through a secure form, scrubbed to what 314(b) permits, and the founders compile and send a twice-weekly digest that each bank checks against new accounts. Track submissions and hits per bank.
keep going if · 4 of 5 banks submit at least 2 confirmed signals each, and at least 1 bank reports a hit (an account blocked or a transaction flagged) from another bank's signal
3. Founding member deposit close
$700 · 21 days
Present the founding offer to all 15 institutions from Experiment 1, in person where possible at one IBAT regional compliance event: $500 per month per institution, five founding slots, price locked two years, screening live within 90 days of signing. Ask for a $1,000 refundable deposit invoiced to the institution to hold the slot.
keep going if · 5 of 15 institutions sign the founding agreement and pay the $1,000 deposit within 21 days of receiving the offer

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.

$1,000

per prospect, refundable

how · A $1,000 refundable deposit invoiced to the institution against a signed founding member agreement, because bank buyers pay invoices through accounts payable, not card checkouts, and a signature from the BSA officer's institution forces the internal vendor conversation the email thread never triggers set up: Stripe Invoicing ↗

what it reserves · One of five founding slots in the Texas cohort, the $500 monthly price locked for two years, first position in onboarding, and a seat on the data governance board

refund · Refunded in full any time before the connector goes live, and automatically if screening is not running within 90 days of signing

target · 5 deposits from 15 institutions offered within 5 weeks

before taking money · Run the pooled pilot only among institutions registered under FinCEN Section 314(b) and share no customer PII before counsel approves the sharing agreement.

Go: build it if

5 Texas institutions sign and pay $1,000 each, and the manual pool produces at least 8 contributed signals and 1 cross-bank hit in two weeks

Kill: stop if

Fewer than 2 deposits after 15 offers, or fewer than half the pilot banks contribute any signal, which means the network is consume-only and the free email thread wins

outreach message

You are probably tracking the same mule accounts as the bank two towns over, through an email thread that dies in someone's inbox. I am building Flagline, a pooled watchlist for Texas community banks: every member's confirmed fraud signals screen every other member's new accounts, with SAR-ready case files. Five founding banks, $500 a month, first screen running within 90 days. Do you have 20 minutes this week to check whether your last three fraud losses would have been caught?

The pooled fraud watchlist Texas community banks run together $500 a month per institution; the founding five lock that price for two years and get a seat on the data governance board Reserve one of five founding slots with a $1,000 refundable deposit

deposit terms

A $1,000 refundable deposit reserves one of five founding member slots in the Texas cohort, locks the $500 monthly price for two years, and puts your institution first in onboarding. It is refunded in full any time before your connector goes live, and automatically if the network is not screening your accounts within 90 days of signing.

The idea in full

What: Flagline is a subscription screening layer that plugs into a community financial institution's core-system exports through no-code connectors, checks every new account and transaction against a live watchlist pooled from all member institutions, and produces SAR-ready case files. Each member contributes confirmed fraud and mule-account signals back to the network, so detection quality rises with every institution that joins. Sold by the founders directly to BSA and compliance officers, with a small field team handling onboarding.
Why now: AML tooling is being rebuilt right now - rubi labs is automating AML data collection for financial institutions in PnP 2026 and MouseCat (yc W26) pitches AI to fight financial crime - yet 75 new companies entered this cluster in 2025 and none of them are building the cross-institution signal pool that small banks lack and big banks have internally.
Wedge: first customer and entry point: Five community banks in one state that already share informal fraud emails; replace that email thread with a connector and a pooled watchlist, priced per institution.
Path to 100x: Financial crime compliance and fraud losses are a $100B+ problem, and consortium data is winner-takes-most: the network with the most confirmed fraud signals catches the most fraud, so every new member makes the next sale easier and defection costlier. Owning the shared watchlist for the roughly ten thousand US community financial institutions, then expanding into payments screening, is the 100x path.
Ceiling: If the network stalls below a few hundred institutions, it stays a regional data co-op worth tens of millions, not the national screening layer.
Closest real companies, as the generator saw them: rubi labs株式会社 automates AML investigation workflows inside one institution; MouseCat and Incandor build detection intelligence sold institution by institution. Flagline's product is the consortium itself - the pooled signal set no single-tenant tool can replicate.
Main risk: Core banking vendors control the integration surface and can bundle a me-too sharing feature before the network reaches critical mass.

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
3/5
Consortium data genuinely tips winner-takes-most, but the buyer pool is roughly ten thousand small institutions with modest per-seat budgets.
Bootstrapper
4/5
BSA officers at community banks already buy AML tooling, compliance subscriptions barely churn, and five banks in one state is a founder sized first sale.
Operator
4/5
BSA officers already trade fraud tips by email, so Flagline replaces an existing habit for a buyer who owns compliance budget and losses.
Technologist
3/5
The pooled fraud signal set genuinely compounds per member, but core banking vendors own the integration surface and can bundle a me-too feed.
Risk
3/5
Ten thousand small institutions is diversified demand, but core banking vendors own the integration surface and can bundle a copy.
trends
2/5
Pooled fraud signals for small banks were equally buildable in 2023; 75 new AML entrants in 2025 signals crowding more than a fresh opening.
