Target user

Everyday online shoppers discovering small brands via TikTok Shop, Instagram, Etsy, and influencer links

Features
  • One-tap URL or domain scan returning a green / yellow / red verdict with a short reason
  • Business registration lookup plus domain age, ownership freshness, and registered address
  • Aggregated review signal across Trustpilot, Reddit, BBB, and site comments
  • Risk flags for hidden WHOIS, recent address change, weak refund policy, and known scam-template fingerprints
Why now

Social commerce (TikTok Shop, Instagram checkout) and direct-to-consumer Shopify brands are exploding; FTC and BBB reports of shopper fraud are climbing; existing tools like ScamAdviser and URLVoid look like 2003 and aren't tuned to the shopper moment of decision.

Demand
7/10

ScamAdviser reports 7M monthly users checking sites before buying, and TikTok Shop removed 700,000 sellers in a single enforcement wave, confirming a real at-purchase trust gap for social-commerce shoppers.ScamAdviser Trust Score Explained: Is a Website Safe?TikTok Shop Tightens Grip on AI-Driven Fraud After Removing 700,000 Sellers

The exact niche is already crowded with shopper-facing tools — StoreVerify, StoreLegit, ShopExaminer, WebSafely, and ScamAdviser all do store-legitimacy checks today, undercutting the '2003-era tools' premise.StoreVerify — Check if a Shopify Store Is LegitShopExaminer - Verify E-commerce Stores Before You Buy

Monetization
4/10

Most direct competitors (StoreVerify, StoreLegit, ShopExaminer) appear free to consumers; shopper browser extensions historically monetize poorly unless paired with B2B API or affiliate/BNPL flows, and that B2B lane is already taken by TrueBiz and ScamAdviser's API.StoreLegit — Check If Any Online Store Is Legit & Safe to Buy FromTrueBiz - Merchant Risk Made Simple

Longevity
7/10

AI-generated clone stores and organized fraud networks are structurally rising (FraudOnTok, 700K TikTok seller removals), so the underlying problem worsens over time and trust signals keep needing fresh data.FraudOnTok: How Scammers Hijack TikTok Shop With Clone Sites and Crypto

Feasibility
6/10

Buildable with off-the-shelf data (WHOIS, business registries, Shopify store signals, reviews) — multiple teams have already shipped near-identical products, so it is straightforward but offers no technical moat.Does a ScamAdviser or ScamDoc score reliably predict online store reliability?
