Risk & Legal

44
Risk · 0-100
STRONG44 / 100

Early-stage franchise with explosive growth claims, opaque profitability metrics, and high investment requirements creates moderate-to-significant due diligence and ROI validation risk.

Score breakdown · what drove the 44 / 100 rating

  1. 01MEDNet income not disclosed despite $926K average revenue — unable to assess actual profitability and validate 7% royalty impact
  2. 02MINORExplosive 300% YoY unit growth (9 to 11 units) is mathematically inconsistent with claimed 11 total units — suggests data inconsistency or aggressive/unsustainable expansion claims
  3. 03MEDHigh initial investment range ($872K-$1.8M) with no disclosed net income creates significant ROI uncertainty and payback period risk
  4. 04MINORMinimum $2,500 monthly royalty floor ($30K annually) represents 3.2% of average revenue baseline, compressing margins for newer/slower locations
  5. 05MINOROnly 11 total units across system limits track record data, peer support network, and supplier negotiating power
