Someone will imitate your brand.
Know the morning it happens.

Brand Guard watches three public feeds every day — new USPTO trademark filings, newly registered domains, and new App Store listings — and emails you when something matches your brand name, including near-miss spellings.

No dashboard to learn. Alerts land in your inbox; data in your pipeline via JSON API.

Trademark filings

Every new USPTO application is checked against your marks — catch a conflicting filing during its opposition window, not after registration.

Lookalike domains

Tens of thousands of domains register daily. We flag the ones containing your brand — including hyphenated and character-swapped variants.

Copycat apps

New App Store listings using your name or a confusable variant, with seller identity, the day they appear in search.

FAQ

Where does the data come from?

Primary public sources only: the USPTO's trademark application feed, daily newly-registered-domain lists, and the App Store search index. Scanned on a fixed daily cycle.

What counts as a match?

Exact and near-miss matches: containment (yourbrand-shop.com), separator tricks (your-brand), and single-character swaps (y0urbrand). Each alert shows the matched term and a confidence score.

How do webhooks and the API work?

Every match can POST to your endpoint with an HMAC-SHA256 signature header, and GET /api/v1/matches returns your full history as JSON. Your API key arrives in the welcome email.

How do I cancel or change terms?

Reply to any alert or welcome email and we handle it same-day, or use the API. Subscriptions are month-to-month through Stripe.
