What KNOW Bio does

KNOW Bio, LLC is a privately held life science incubator headquartered in Morrisville, North Carolina (within the Research Triangle Park area), founded and led by CEO Neal Hunter. The company forms and operates wholly-owned or majority-owned subsidiaries that commercialize its proprietary intellectual property in nitric oxide release chemistry and precision visible-light (LED) therapy. As of 2026, the portfolio comprises EmitBio (light-based therapies for respiratory infections, including an investigational at-home COVID-19 device), Revian (the FDA-cleared REVIAN RED wireless all-LED hair-growth cap for androgenetic alopecia, sold direct-to-consumer via revian.com and through dermatology/aesthetics providers), Vast Therapeutics (development-stage NO-releasing anti-infectives targeting Pseudomonas aeruginosa in cystic fibrosis), Diabetic Health (NO coatings for continuous glucose monitoring sensors and insulin infusion sets, formed via the 2019 acquisition of Clinical Sensors), and Digestive Health Therapeutics (NO applications for gastroenterology). The corporate strategy is to develop each subsidiary to proof-of-concept and then pursue a sale, IPO, or other independent financing event for that subsidiary.

KNOW Bio's underlying technology platform combines two pillars: tunable macromolecular nitric oxide-release scaffolds with controllable payload, release rate, and release location (developed by Chief Scientific Officer Mark Schoenfisch, who has 100+ peer-reviewed NO publications), and patented precision light therapy — most notably EmitBio's U.S. Patent 11,147,984 (issued November 2021, lifetime through 2040, covering oral light devices to inactivate SARS-CoV-2 and other pathogens) and Revian's dual-wavelength (620 nm + 660 nm) LED technology that stimulates endogenous NO production to reduce inflammation, increase local blood flow, and inhibit DHT. In vitro, Revian's combination reduced DHT production by 74% versus 38% for finasteride at 24 hours, and EmitBio's device achieved 99.9% SARS-CoV-2 viral load reduction and >48-hour faster symptom clearance in a randomized Phase I/II trial, supporting an FDA Emergency Use Authorization submission.

The revenue model is currently anchored on direct hardware sales of the REVIAN RED System, with planned future revenue from EmitBio device sales and global technology licensing, plus subsidiary-level exit/financing events. The company employs a small core team (51-100 employees) augmented by contractors and shared services, with Revian now building a national U.S. field sales force (Regional Directors for West, Central, and East regions appointed 2025-2026) alongside its direct-to-consumer e-commerce channel and academic clinical study partnerships with Wake Forest University School of Medicine and Spectrum Advanced Aesthetics. Pricing is not publicly disclosed. Total disclosed institutional funding is approximately $55 million, with Reedy Creek Investments, LLC as the sole disclosed investor across a December 2018 $25M corporate commitment and a May 2019 $30M equity round; no subsequent funding events are disclosed.

Revenue model

1. Subsidiary exit / IPO / financing events: KNOW Bio's corporate strategy is to form operating subsidiaries, develop them to proof-of-concept, then pursue a sale, IPO, or other financing around each subsidiary to generate capital for the other operating companies and returns to investors.
2. Direct hardware sales of REVIAN RED System: Sale of the FDA-cleared REVIAN RED wireless wearable LED hair growth cap directly to consumers via revian.com and through healthcare providers for at-home treatment of androgenetic alopecia in men and women.
3. Future drug/device revenue from EmitBio light therapy platform: Investigational EmitBio device and pipeline targeting at-home treatment of mild-to-moderate COVID-19 and other respiratory infections; pipeline includes prophylactic and therapeutic applications of visible-light technology. Not yet commercially available pending FDA action.
4. Future drug revenue from Vast Therapeutics (anti-infectives): Development-stage therapies (via Vast Therapeutics) targeting resistant bacterial infections in cystic fibrosis and other respiratory diseases; intended to be advanced to clinical trials and commercialization via subsidiary financing events.
5. Licensing of EmitBio light technology to global partners: EmitBio explicitly stated its goal of licensing the technology to global partners so that everyone has rapid access to the treatment, indicating a licensing/royalty component to the long-term revenue model.
