Sensory Cloud

What Sensory Cloud does

Sensory Cloud, Inc. is a Boston, Massachusetts-based private company that built and sold FEND, a proprietary calcium-enriched airway hydration mist designed to hydrate upper airways for 4–6 hours and help clear inhaled airborne particles. The product uses a precision-engineered micro-mist of water, calcium chloride, and trace magnesium in a proprietary blend, with droplet sizing engineered to reach the larynx and trachea — deeper than standard saline nasal sprays. FEND was invented by Dr. David A. Edwards at Harvard University and earned TIME Magazine's Invention of the Year (2020) and Fast Company World Changing Idea (2021, 2022) recognition. The company reported over 32,000 customers through its direct-to-consumer e-commerce storefront at hellofend.com.

The commercial model is direct-to-consumer only, sold within the United States at $29.99 for a one-time purchase of the Pocket Mister (approximately 30 days of daily use at 3 breaths, 3 times per day) or $19.49 per month on a subscription basis through the Recharge platform. Geographic reach is limited to domestic shipping only — international orders are not fulfilled — and customer support is delivered via email and a Boston-based phone line. The company is small (1–10 employees), privately held, with no disclosed institutional investors beyond two 2022 rounds (Seaside Ventures and Half Court Ventures) and no disclosed revenue.

In 2025 the company announced a strategic pivot from consumer wellness into a clinical research organization developing therapeutics for chronic cough and other inflammatory conditions of the upper airways. As a result, the FEND consumer business is being sunset on June 30, 2026, with all subscriptions terminating, the online store closing, and customer support ending July 31, 2026. Going forward, value creation depends on the yet-to-be-disclosed clinical pipeline and any future regulatory or commercial milestones in respiratory therapeutics.

Direct peers

• NeilMed Pharmaceuticals: NeilMed is the dominant consumer nasal saline brand (squeeze bottles, neti pots, isotonic and hypertonic sprays). It is the most direct comparator to FEND's nasal/airway mist positioning and competes for the same health-conscious consumer seeking drug-free nasal and sinus hydration.
• Xlear: Xlear sells xylitol-based nasal sprays and sinus care products marketed as natural drug-free solutions for upper airway hygiene. It is highly comparable to FEND on ingredient philosophy (natural, drug-free nasal cleansing) and DTC retail channel, making it a close functional peer.
• Bellus Health: Bellus Health is a clinical-stage company developing therapeutics for chronic cough (BLU-5937, a P2X3 antagonist), the exact indication Sensory Cloud is pivoting toward. It is the most direct therapeutic-program comparator for the post-pivot business.
• Acorda Therapeutics: Acorda commercializes Inbrija, the inhaled levodopa product invented by Sensory Cloud founder Dr. David Edwards. It is comparable both as a precedent for inhaled airway delivery therapeutics and as a business-model reference for what a successful Edwards-originated inhaled therapeutic can look like at commercialization.

Emerging players

• Trevi Therapeutics: Trevi Therapeutics is developing nalbuphine extended-release for chronic cough in idiopathic pulmonary fibrosis and other refractory cough indications. It is a comparable emerging clinical-stage peer in the same chronic cough therapeutic space Sensory Cloud is entering.

Broad incumbents

• Simply Saline (Bayer): Simply Saline is Bayer's consumer saline nasal spray brand sold across mass retail. It is the incumbent mass-market competitor to FEND in the saline nasal spray category and represents the type of large-CPG competition Sensory Cloud faces on retail shelves.
• Vicks (Procter & Gamble): Vicks is P&G's flagship consumer respiratory brand (Vicks VapoRub, inhalers, humidifiers, cough/cold products). It is a broad incumbent in consumer respiratory wellness and the type of large portfolio player against which any new airway-focused entrant must differentiate.
• Church & Dwight (Arm & Hammer / Nasal Care): Church & Dwight owns Arm & Hammer and acquired the Vicks-style nasal care and saline product lines. As a CPG conglomerate with broad respiratory wellness exposure, it is a relevant incumbent peer for any consumer or OTC airway hydration product.
• Merck & Co. (Chronic Cough Program): Merck has invested in the chronic cough therapeutic category through its P2X3 antagonist program (gefapixant, developed with Afferent). It is the dominant large-pharma peer pursuing the same therapeutic endpoint Sensory Cloud is now targeting, representing both the opportunity size and the competitive ceiling.

Regional players

• HydraSense (Church & Dwight): HydraSense is a Canadian nasal saline brand (now under Church & Dwight) with strong market share in Canada and Europe. It is comparable as a regional nasal saline peer with similar drug-free hydration positioning, illustrating an alternative international scaling path for FEND-style products.
