Key insight: Vendors intentionally bury pricing changes in T&C updates because most customers never notice — an automated monitor turns that asymmetry into a $30/month recurring revenue stream for catching $10k+ in unexpected charges per customer per year.

The Problem

Companies subscribe to dozens of SaaS tools but rarely re-check their contracts or pricing pages. Vendors frequently change terms, add minimum seats, or shift from monthly to annual billing without clear notification. Teams wake up to surprise $5k charges or discover they're now locked into 3-year contracts they didn't agree to.

Target Audience

Finance ops teams and startup founders managing 10+ SaaS subscriptions; cost-conscious CTOs at mid-market companies (50-500 employees)

Why Now?

AI tools like Claude make contract parsing trivial; Cursor enables solo builders to wire scraping + APIs quickly; SaaS bloat is hitting critical mass as companies discover 30% of subscriptions go unused or overcharged

What's Missing

Existing SaaS management tools focus on spend analytics and consolidation, not on detecting unauthorized vendor-side changes. Manual contract review is the current solution — slow, unreliable, and nobody does it.
