The Problem

One missed sanction hit can end your fintech startup

OFAC fines start at $50,000 per violation. Most early-stage fintechs don't find out until it's too late.

💸

$50K+ per violation

OFAC civil penalties for processing a single sanctioned payment can reach six figures — and they're per transaction.

🐌

Manual lists are useless

Existing tools dump raw CSV lists on your compliance team. No reasoning, no context, no entity resolution.

🔥

Found during due diligence

Series B investors and acquiring banks run compliance checks. A single violation kills deals and banking relationships.

Real-time or useless

Batch screening that runs nightly misses the window to prevent the transaction. You need a decision in milliseconds.

How It Works

Live in 60 seconds. Serious protection from day one.

1

Connect Stripe

Paste your Stripe API key. Sentinel starts listening to your webhook stream instantly.

2

Screen Every Payment

Every transaction is matched against the OFAC SDN sanctions list in real time — primary names and all known aliases.

3

AI Entity Resolution

Claude AI distinguishes "John Smith the US customer" from "John Smith on the OFAC list" — eliminating false positives.

4

Instant Alert + Audit Log

Get Slack/email alerts on hits. Every decision is logged with full reasoning for your compliance team and auditors.

Features

Everything your compliance team actually needs

Real-Time Screening

Every payment is screened the moment it's created — not in a nightly batch. Stripe webhooks trigger an instant check on every transaction.

🤖

AI Entity Resolution

Powered by Claude AI to reason about name matches in context — not just string comparison. Eliminates false positives on common names.

🇺🇸

OFAC SDN List

Screens against the full US Treasury Specially Designated Nationals list, including all AKAs and aliases. Updated every 24 hours directly from treasury.gov.

📋

Immutable Audit Trail

Every check logged with full AI reasoning — accessible via your compliance dashboard and API. Ready for regulators, investors, and banking partners.

🔔

Instant Alerts

Slack and email notifications the moment a high-risk transaction is detected. No dashboard monitoring required.

🔒

No Sensitive Data Stored

No card numbers or payment credentials ever stored. Sentinel only retains the name, amount, and AI reasoning needed for your compliance record.

Why Sentinel

Built for startups, not enterprise compliance teams
