You’re About to Invest $200,000+ in a Business You Can’t Fully See.
The Franchise Disclosure Document can run 300+ pages of legal language designed to protect the franchisor, not you. Most buyers read it and think they understood it. They didn’t.

Built for People Who Read the Fine Print.
First-Time Franchise Buyers
You’re evaluating your first franchise. The FDD is overwhelming. You need to know what matters before you hire an attorney, and what to ask them when you do.
Multi-Unit Operators
You’re adding a brand to your portfolio. You’ve seen how franchisors hide fee escalation and territory erosion. You want data, not marketing decks.
Franchise Attorneys & Advisors
You represent buyers. You need a forensic pre-screen before you bill $5,000 in review time. We surface the 5 things that matter most in 60 seconds.
Compliance Isn’t Transparency.
What a Standard FDD Review Catches
Is the document properly formatted? Are required disclosures present? A franchise attorney ensures the FDD is legally compliant. That’s their job, and it’s important. But legal compliance and transparency aren’t the same thing.
What It Misses
Which units were excluded from the earnings claim, and why? Can the marketing fund you pay into be spent selling new franchises? Does the fine print quietly cut your window to bring a claim down to twelve months? Does the growth headline net out the transfers and buybacks?
These aren’t legal defects. They’re behavioral patterns that only surface through forensic analysis.
Someone I care about signed a franchise agreement a few years back. They were smart. Careful. They read the FDD — all 164 pages. They did everything right. And they still got burned.
Not because they were careless. Because the system is designed that way. 207 pages of legal language aren’t there to inform you. They’re there to protect them.
I built Franchise Sonar because I wanted something that didn’t exist: a tool that reads an FDD the way a forensic auditor would. Not to decide whether you should buy — but to make sure you see what the franchisor would rather you didn’t.

But Can't I Just Ask a Chatbot?
You can—and you'll get a confident, complete-looking answer in two minutes. What you won't get: any way to know which numbers are wrong, what's on the scanned pages it never read, or whether this brand's terms are normal—or the worst in their category. We extract 202 fields with two independent reads, a page citation on every value, and a library of 1,926 FDDs across 1,500+ brands to say what's unusual. The difference isn't the summary. It's knowing it's right. A chatbot reads the one FDD you hand it. When we hold the brand's prior filing, we compare the two and show you what changed.
What Goes Into Every Score.
Franchise Sonar analyzes public Franchise Disclosure Documents filed with state regulators. We surface patterns. We don’t make investment recommendations.
