A Sanabul spin-off building a combat-sports skin defense brand · Y1 launch forecast for board review
What you're looking at. Corner Supply Co is a combat-sports skin defense brand spun out of Sanabul, targeting the same audience as the parent brand — BJJ practitioners, MMA fighters, wrestlers, boxers. Two products launch concurrently: an antifungal body wash (16oz and 32oz) for post-training skin defense against ringworm, staph, and athlete's foot, and an HOCl spray for hands, face, and equipment during sessions. The direct incumbent is Defense Soap ($36.99 at 2,810 units/mo on the 32oz, single-seller mature listing). Sanabul's 100,000+ engaged combat-athlete email list is the launch oxygen — it bypasses cold-launch ad burn, accelerates review accrual, and supports premium pricing in the $25–35 band.

The model rebuilds every chart, KPI, and table instantly. Default view is Sanabul Launch — the other three scenarios show what the spreadsheet would produce under standard cold-launch assumptions for comparison.
SKUs in Launch
Click any SKU to include or exclude it from the launch mix. Defense Soap competes directly with the body wash; HOCl is a separate combat-sports use case (hands, face, mat equipment).
Definitions.Breakeven Month = first month with positive monthly net profit that remains broadly positive through Y1 (a SKU can have a positive M1 from email injection but if M2–12 are negative, breakeven = "Not in Y1").
Payback Month = first month at which cumulative NP ≥ 0, conditional on Y1 ending positive — a SKU with negative Y1 NP never reaches payback in Y1 even if it has individual positive months.
Launch Budget = max(first PO at MOQ × landed COGS, 6 months velocity × landed COGS) + sum of negative monthly NP + $12K one-time setup (photos, A+, Vine, brand registry).
ROI = Y1 Net Profit ÷ Launch Budget — what you get back for the capital deployed.
Defense Soap is the strategic target — same audience, dated brand, no marketing engine beyond Amazon SEO. Truremedy is the medical-natural alternative; not the same buyer. Mass-market brands (Botanic Hearth, everyone for every body) compete on price, not on combat-sports positioning — they're irrelevant to the launch thesis.
