Frequently asked questions

Frequently Asked Questions

How much does it cost to open a Serotonin franchise?

The total investment to open a Serotonin franchise ranges from $905K – $1.8M, with an initial franchise fee of $59K. This includes real estate, equipment, inventory, and working capital as disclosed in their Franchise Disclosure Document (FDD).

What do Serotonin franchise owners earn?

Item 19 of the Serotonin FDD discloses outlet figures from $588K to $1.4M but no single average across all outlets. These are gross sales figures, not profit; the Revenue section shows what the filing reports and on what basis. Item 20 of the FDD lists current and former franchisees; asking them directly is the standard way to fill this gap.

Who owns Serotonin?

Serotonin is franchised by Serotonin Enterprises LLC. Its parent company is Longevity Brands, LLC. Source: FDD Item 1, 2026 filing.

What is Item 19 in the Serotonin FDD?

The FDD section where a franchisor may disclose financial performance of its outlets. Disclosure is optional and formats vary; figures are typically gross sales, which is revenue before expenses, not profit. FranchiseVerdict extracts these figures directly from the Serotonin FDD and qualifies whose outlets they describe.

What is Serotonin's franchise failure rate?

SBA 7(a) loan charge-off data is not available for Serotonin (fewer than 10 loans on file). Charge-off rates are one way to gauge franchise risk, but not all franchise loans go through the SBA program. We recommend reviewing turnover and closure data in the FDD and speaking with current franchisees.

How many Serotonin franchise locations are there?

As of their most recent FDD filing, Serotonin has 11 total units in the United States, including 8 franchised units and 3 company-owned units. 7 new units were opened in the latest reporting year.

Is Serotonin a good franchise to buy?

FranchiseVerdict rates Serotonin as a C-grade franchise with a verdict score of 41 out of 100 (higher is better). The grade is a deterministic score built from six weighted dimensions — financial health, unit economics, unit growth, scale, legal, and transparency — then calibrated against SBA loan charge-off rates and FDD age. Transparency is one of the six, so a filing that discloses less scores lower on that dimension than one that discloses more. Our rating is based solely on publicly available FDD and government data; we recommend speaking with current franchisees before making any investment decision. This is not investment advice.

Data sourced from public FDD filings and SBA 7(a) FOIA records. Not financial advice.
