5 Unique Scenarios

Every case runs a different
investigation playbook.

Each fraud type has its own workspace, evidence sources, and resolution path. The system collects evidence progressively in 3 waves — internal signals, external signals, then deep analysis — so you see the investigation happen live.

5
Distinct playbook workspaces
Chargeback — Representment Builder
$4,500 dispute with GPS delivery proof, Instagram social evidence, and cross-merchant dispute history. Builds a complete representment narrative with win likelihood.
Evidence: OMS · Logistics · Social · Disputes
Account Takeover — Recovery Controls
SIM swap attack with impossible travel, 3 cash-out transactions in 35 minutes. Attack timeline, session revocation, and customer comms draft. Includes a device API timeout for realism.
Evidence: IAM · Carrier · IP Intel · Device
Return Abuse — Refund Hold
Serial wardrobing across 4 store locations — 78% return rate with social media proof. Policy rule evaluation, recommended paths, and LP referral.
Evidence: OMS · POS · Policy · Social · LP
Loyalty Fraud — Points Reversal
Insider promo exploitation with 12x velocity spike, linked accounts, and expired code bypass. Points accrual graph, network cluster analysis, and rule change suggestion.
Evidence: Loyalty · Promo · HR/IAM · Network
Synthetic ID / BNPL — Compliance Packet
Fabricated identity exploiting 3 BNPL providers — SSN age mismatch, fraud ring address link. Identity signal cards, risk explanation, SAR filing, and multi-provider notifications.
Evidence: Credit Bureau · BNPL · Compliance DB
The Challenge

Fraud investigation is fragmented and manual

Analysts juggle dozens of browser tabs, copy-paste evidence between systems, and write reports from scratch — while SLAs tick down and fraud losses mount.

Today
Tab-hopping, copy-paste investigations
Evidence gathered manually across 7+ disconnected systems
Same investigation template used for every fraud type
No audit trail of what was checked, when, and by whom
Writebacks to downstream systems done manually or forgotten
With Lumi
Progressive investigation, single pane of glass
Evidence collected progressively in 3 waves from all systems
5 unique playbook workspaces tailored to each fraud type
Full audit trail with grouped entries, systems touched, artifacts
Automated writebacks to payment, CRM, compliance, and LP systems
How It Works

What Makes It Real

Not a mockup — a working investigation system

Every interaction in the demo reflects real fraud ops workflows. Here's what sets it apart from typical product demos.

Progressive Evidence Collection
Evidence doesn't appear pre-filled. Click "Run Playbook" and watch skeleton rows flip to verified, flagged, or missing — in 3 timed waves across internal and external sources.
Scenario-Specific Workspaces
Each fraud type loads a completely different workspace — representment builder, attack timeline, refund path selector, points graph, or identity signal cards. Not the same template with different text.
Human-in-the-Loop Approvals
The system recommends — but a human decides. Every case has a named approver, a confidence score with stated limitations, and the publish action is gated behind explicit sign-off.
Lean Grouped Audit
8-12 audit entries per case — not a firehose. Each entry logs the actor, systems touched, artifacts produced, and policy version. Replayable runs with unique IDs.
Source Unavailability
One case includes a deliberate API timeout — a device reputation service fails, evidence is marked "UNAVAILABLE" with a fallback note. Confidence adjusts downward. Real systems fail; ours handles it.
Sidecar Writebacks
After approval, writebacks execute progressively to payment processors, CRM, compliance databases, and loss prevention — each with a record ID and visual confirmation. Then "Open Next Alert" loops to the queue.
Demo Walkthrough

5 cases, 5 different investigations

Each case in the demo queue represents a distinct fraud scenario with its own playbook, evidence sources, and resolution path.

01
Chargeback Abuse — "Never Delivered"

02
Account Takeover via SIM Swap
$7,200 in 35 minutes across 3 merchants after a SIM swap. Attack timeline, session revocation, device API timeout (realism trick), and customer security notification.
03
Return Abuse — Serial Wardrobing
Fashion influencer with 78% return rate across 4 stores in 60 days. Policy rule evaluation (3 of 6 fail), social media cross-reference, and refund hold recommendation.
04
Loyalty Points — Insider Exploitation
47,200 points accrued at 12x velocity with expired promo codes. Linked accounts from same address/device, network graph cluster, and points reversal with rule change suggestion.
05
Synthetic Identity — BNPL Bust-Out
Fabricated identity with SSN belonging to a minor. $4,740 across 3 BNPL providers, fraud ring address link. SAR filing, multi-provider block, and compliance watchlist.
