THE WORLD’S FIRST DC SAUNA HEATER™

NO INVERTER. NO GRID. NO POLLUTION.

 

THE PROBLEM: THE "OLD-WORLD" SAUNA

• EMISSIONS: Wood-burning units face increasing environmental bans due to smoke and particulate matter.

• POLLUTION & WATER WASTE: Grid-tied AC heaters rely on centralized power plants that generate massive carbon emissions and consume billions of gallons of water.

• HIGH POWER BILLS: 240V AC electric heaters are massive energy hogs that spike residential and commercial utility costs.

• GRID-SURGE VULNERABILITY: AC heaters are prone to catastrophic failure and frequent element burnouts from grid-surges and brownouts.

• THE WARRANTY GAP: Most AC manufacturers offer only a limited 1-year warranty, reflecting a lack of long-term hardware reliability.

• THE INVERTER TRAP: Off-grid setups currently require expensive, inefficient inverters that waste ~10%+ of power just to function.

 

THE SOLUTION: THE 48V DIRECT-CURRENT "DC" SOLAR-SAUNA HEATER™

We have engineered the world’s most efficient 5kW DC Electric Sauna Heater™. By eliminating the grid and the inverter, we deliver pure, 100% sustainable heat.

• DIRECT-DC TECH: Plug-and-play 48V power. 0% conversion loss. ~100% efficiency.

• ZERO EMISSIONS: 100% clean energy from panel to stone. No smoke, no carbon emissions.

• RESOURCE INDEPENDENCE: No grid-based water waste or power plant reliance.

• LOW-VOLTAGE SAFETY: 48V DC is safer and easier to install than 240V AC, saving customers thousands in electrical contractor fees.

• UNIVERSAL STORAGE: Native compatibility with LiFePO4 and next-gen Sodium-Ion batteries.

 

THE SELF-FINANCING ENGINE

We don’t just build saunas; we own the Direct-DC Sauna™ category. Our high-margin DTC model is engineered so the profits from each phase fully capitalize the next factory run—even with higher initial manufacturing costs.

• PHASE 1: The "Founder’s Fifty" (50 Units)

  • Unit Revenue: $12,488 | Unit COGS: $2,500

  • Target Gross Profit: $499,400 USD

  • Buying Power: This profit alone pays for 199 units for Phase 2—fully funding the next factory order in full, upfront.

• PHASE 2: The Pilot Expansion (200 Units)

  • Unit Revenue: $12,488 | Unit COGS: $2,250 (Volume Discount)

  • Target Gross Profit: $2,047,600 USD

  • Buying Power: This profit pays for 1,000+ units for Phase 3—fully funding our jump to the 1,000-unit mass market.

• PHASE 3: Market Entry (1,000 Units)

  • Unit Revenue: $12,488 | Unit COGS: $2,000 (Supply Chain Optimization)

  • Target Gross Profit: $10,488,000 USD

  • Buying Power: This profit pays for 6,000+ units for Phase 4—fueling our leap into total vertical integration.

• PHASE 4: Vertical Scale-Up (5,000 Units)

  • Projected Revenue: $62,440,000 USD

  • Estimated Net Profit: $54,940,000 USD (Pre-Tax @ $1,500 COGS)

 

THE STRATEGIC RAISE

$250,000 PRE-SEED for 5% Equity. (Implied $5,000,000 Post-Money Valuation).
Up to 50% Equity available for prominent CEO/COO/CFO & CTO roles. This capital is the last required bridge to activate our self-funding manufacturing loop.

 

USE OF FUNDS:

• REGULATORY & IP: Finalizing ETL Certification (UL 499) and filing Utility Patents for our proprietary 48V DC architecture.

• ENGINEERING & TOOLING: Proprietary 5kW DC heater shell and final PCBA programming for the Wi-Fi/Digital control system.

• PILOT INVENTORY & LOGISTICS: Production deposits for the "Founder’s Fifty" and establishing 3PL fulfillment.

• MARKETING & WEB: High-conversion DTC website, professional "Founder’s Series" video, and targeted lead-gen.
