Executive Summary

Millions of vulnerable end users and the SMBs that serve them are routinely targeted by social-engineering scams across marketplaces, fintech apps, messaging platforms and support channels, and conventional rule-based defenses struggle to detect these nuanced attacks. Small businesses—roughly 2M addressable customers in this model—face rising fraud costs, customer churn, and reputational damage while lacking specialized security teams. You could build a SaaS product that fuses modern LLM and multimodal AI detection with crowdsourced community signals and native platform integrations to flag and remove scam content in real time, exposed via an API, dashboard, and lightweight SDKs. Target a tiered subscription model at roughly $3K ACV with consumer-facing warnings, incident workflows, and community-verified evidence to accelerate trust decisions. The market looks attractive now: a $6.0B TAM (2M SMBs × $3K ACV) with a market score of 90/100 and revenue potential of 86/100, driven by platform proliferation and growing demand for integrated fraud protection. Advances in LLMs and multimodal models plus maturing community-powered signals make higher-accuracy, earlier detection commercially viable today. You can differentiate by tightly combining high-precision AI models, verified crowdsourced signals, and deep platform integrations to reduce false positives and surface novel scams faster than incumbents. Real challenges include sourcing quality signal data at scale, preventing community gaming, maintaining privacy/compliance, and integrating across diverse platforms, but successfully addressing these gives you a defensible, high-value product.
