Stream2Sea

What Stream2Sea does

Stream2Sea is a privately held beauty and personal care company founded in 2015 by cosmetic chemist and diver Autumn Blum. The company manufactures reef-safer mineral sunscreens and biodegradable personal care products at an FDA-registered, ISO 22716-certified facility in Bowling Green, Florida, employing 101–250 staff. Products are sold direct-to-consumer via a Shopify storefront, through Amazon and iHerb marketplaces for international reach, and via wholesale programs serving dive shops, outdoor retailers, resorts, and a Pro Deal program for diving professionals.

Core products include mineral-based sunscreens (SPF 20–45) built on non-nano titanium dioxide and zinc oxide, featuring the patented WetBoost™ technology that demonstrated a 45% increase in measured SPF after 80 minutes of water immersion. The Coral Care™ line carries Reef Protection Factor certification and was shown to boost healthy coral growth by up to 29% in University of Derby trials. The proprietary Reef Safer™ formulation standard tests complete formulations (not just ingredient exclusions) for aquatic toxicity, biodegradability, and effects on C. elegans, freshwater fish, saltwater fish, and coral larvae. The product portfolio also includes USDA Certified 100% Biobased shampoo bars, biodegradable body care, dive accessories (mask defog, gear wash, ear rinse), after-sun care, and travel-ready bundles.

Revenue is generated through three primary streams: direct-to-consumer e-commerce at retail price points ($4.95–$28.95 standard sizes, $54.95–$239.99 bulk/refill sizes), third-party marketplace sales, and wholesale/bulk sales to specialty retailers and resorts. The customer base is distributed across four primary segments—water sport and diving enthusiasts, families with young children, eco-conscious consumers, and travelers to destinations with sunscreen regulations (Hawaii, Palau, USVI, Bonaire). Marketing emphasizes scientific transparency, community-driven word-of-mouth, and a Stream2Sea Rewards loyalty program.

Direct peers

• Badger Balm: Badger Balm is a closely comparable direct peer: a small, founder-led U.S. brand selling mineral-based, reef-safe sunscreens and natural personal care products with a strong eco/ingredient-conscious positioning. Both brands compete for the same dive, surf, and outdoor specialty retail shelf and target consumers seeking clean, reef-safer alternatives.
• Goddess Garden: Goddess Garden is a direct peer offering mineral-based, reef-safe sunscreens and natural skincare for families and outdoor users. It competes head-to-head with Stream2Sea in the natural and reef-safe sun care segment across both DTC and specialty retail channels.
• Suntegrity: Suntegrity is a direct peer offering mineral, reef-safe sunscreens and clean beauty skincare with comparable eco-conscious positioning and DTC/wholesale distribution. Both brands emphasize non-nano minerals and clean formulations targeted at active, health-conscious consumers.
• All Good Products: All Good is a direct peer brand specializing in mineral, reef-safe sunscreens and organic skincare with a similar ocean-environmental mission and clean-ingredient positioning. The brands overlap meaningfully on retail buyer guides, dive/outdoor shelf placement, and eco-conscious consumer targeting.
• Raw Elements USA: Raw Elements USA is a direct peer focused on reef-safe and ocean-friendly mineral sunscreen sticks and lotions, frequently featured in the same reef-safe buyer's guides as Stream2Sea. The brands share target customers (surfers, divers, eco-conscious families) and compete in the same specialty retail and DTC channels.
• Thinksport / Thinksuncreen: Thinksport's Thinksuncreen line is a direct peer in mineral, reef-safe sun care with strong penetration in outdoor specialty retail and youth/family segments. Both brands compete for sport, family, and active-lifestyle consumers and frequently appear side-by-side on natural sun care retail shelves.

Emerging players

• Dr. Bronner's: Dr. Bronner's is an emerging player in reef-safe and natural sunscreen, expanding from its soap and body care core into mineral sunscreen sticks. It overlaps with Stream2Sea on natural, organic, and ocean-friendly consumer positioning, and is increasingly present in the same dive and outdoor retail channels.
• Reef Repair: Reef Repair is an emerging niche brand in the reef-safe and coral-restoration personal care space, with a mission closely aligned to Stream2Sea's. It represents a smaller, more mission-focused entrant that competes for the same eco-conscious consumer and dive/outdoor retail buyer.

Broad incumbents

• Australian Gold: Australian Gold is a broad incumbent sun-care brand with a mineral/reef-friendly product line spanning body, sport, and botanical collections. It competes broadly with Stream2Sea in the sunscreen category but at much greater scale and broader mass-market distribution rather than a reef-safe niche.
• Sun Bum: Sun Bum is a broad incumbent sun-care and personal care brand with mineral, reef-friendly, and sport sunscreen lines. While far larger and broader in portfolio than Stream2Sea, it directly competes in the water-sport and beach sunscreen category and is the type of well-capitalized brand Stream2Sea must out-niche to retain shelf space.
