- MindImmune Therapeutics
Led · Equity · Mar 2026
MindImmune Therapeutics engineers therapies that target the immune system’s role in neurodegeneration, aiming to curb the neuroinflammatory processes that accelerate diseases like Alzheimer’s. Its research identifies and modulates specific biological pathways responsible for inflammation-driven neuronal damage. The company is advancing a new class of drug candidates designed to meaningfully change the course of neurodegenerative disorders rather than merely treating symptoms. With its latest capital, MindImmune plans to complete critical translational studies and prepare an Investigational New Drug (IND) submission to the FDA. The funding will also underwrite strategic planning for the program’s first clinical trials, bringing its lead candidates closer to human testing. Although revenue figures have not been disclosed, the $5 million infusion strengthens the firm’s financial runway as it moves from preclinical work toward early clinical development.
- Circular Genomics
Participated · Series A · Dec 2025
Circular Genomics is building a proprietary circular RNA (circRNA) biomarker platform that analyzes highly stable, brain-enriched non-coding RNAs from whole blood to detect neurological disease biology before symptoms appear. Its lead application is an Alzheimer’s disease assay designed to outperform current PET and CSF diagnostics by providing an accessible, pathway-level view of neurodegeneration. The company’s data show robust prediction models, identification of presymptomatic patients, and specificity versus other dementias, positioning the test for use in early screening, patient stratification, and longitudinal monitoring. Beyond Alzheimer’s, Circular Genomics plans to expand its platform into other neurodegenerative and psychiatric conditions such as Parkinson’s disease, major depressive disorder, and bipolar disorder. Near-term priorities include completing large clinical validation studies, enhancing the biomarker panel, forming strategic partnerships with pharma and diagnostic providers, and growing the commercial and scientific teams. The recent $15 million Series A financing provides the capital required to advance these initiatives and prepare the first assay for market launch.
