  NuvOx Pharma

  Health

  NuvOx Pharma is a clinical-stage biotechnology company, founded in 2008 and based in Tucson, Arizona, that is developing a first-in-class oxygen therapeutic platform. The company's work focuses on reversing tissue hypoxia, a condition where cells do not receive enough oxygen, which is a contributing factor in many life-threatening diseases. His research on microbubbles led to the discovery that they could carry significantly more oxygen than liquids, forming the basis for NuvOx's technology. Dr. Johnson contributes over 20 years of experience in R&D and regulatory affairs, specializing in pharmacokinetics and formulation. The company's lead product candidate, NanO2™, is an injectable drug composed of dodecafluoropentane nanobubbles that captures oxygen in the lungs and transports it to oxygen-deprived tissues. This platform technology is designed to be synergistic with existing standards of care, enhancing their effectiveness. The business model centers on advancing NanO2™ through clinical trials to gain regulatory approval for various indications. The primary customers are comprehensive care centers for oncology, stroke, and respiratory illnesses, with a long-term strategy of partnering with large pharmaceutical companies for global commercialization. NanO2™ has demonstrated a therapeutic effect in over 30 animal studies and has shown positive safety and efficacy data in completed Phase Ib/IIa human trials for glioblastoma (a type of brain cancer) and acute ischemic stroke. As a radiosensitizer, it aims to make cancer cells more susceptible to radiation and chemotherapy by increasing tumor oxygen levels. For stroke patients, it acts as a neuroprotectant, preserving brain tissue until blood flow can be restored. The company is advancing its clinical programs, with a Phase IIb trial underway for glioblastoma in the U.S. and another Phase IIb trial for stroke planned to begin in the U.K. in 2025. NuvOx has received significant non-dilutive funding from organizations like the National Institutes of Health (NIH) and BARDA, and has also raised capital from various angel investor groups.

  OrgRecon

  Security

  OrgRecon is a security-focused company that provides owner-authorized assessments for Salesforce platform owners and security teams. The firm specializes in identifying and mitigating data exposure risks to anonymous guest users on Salesforce and Experience Cloud platforms.The core service examines public-facing digital assets from an unauthenticated guest perspective, meaning no Salesforce credentials or authenticated sessions are required to perform the scans. OrgRecon's process involves mapping public routes, components, APIs, objects, and fields to uncover what is unintentionally exposed. The platform validates any observable exposure through non-mutating requests, ensuring that the assessments do not alter the client's data or system.A key aspect of OrgRecon's methodology is its deterministic and evidence-based approach. Findings are supported by reproducible evidence, and the company explicitly states that discovery alone is never labeled as exposure. This ensures that clients receive accurate and actionable intelligence. After a vulnerability is deterministically verified, the platform utilizes AI to explain the evidence and provide clear, practical remediation steps. Clients can then use the platform's rescan functionality to verify that the implemented fixes have resolved the exposure.While its initial focus is on the Salesforce ecosystem, OrgRecon's evidence-first assessment model is designed for future expansion across other enterprise digital experience platforms. The company is currently operating in a beta or Minimum Viable Product (MVP) phase, with access available on an invite-only basis.
