- Neuronostics
Participated · Equity · Jun 2026
Neuronostics develops BioEP, a clinically validated digital biomarker platform that analyses standard EEG recordings using eight predefined computational biomarkers and produces a report in under five minutes. The platform is UKCA-marked and ISO-13485 certified and has been validated across 15 NHS sites with over 1,000 recordings. NHS service evaluations are underway at multiple Trusts, including The Royal Wolverhampton NHS Trust and University Hospitals Dorset, and the company has a strategic partnership with Stratus to support scalable US deployment. Neuronostics plans to pursue FDA clearance (with a submission planned for 2026) and to extend the platform to provide brain fingerprints of treatment response in pharmaceutical trials. The company highlights clinical needs such as long diagnostic wait times, high misdiagnosis rates, and the high rate of inconclusive routine EEGs as drivers for its adoption.
- Rejoni
Participated · Series C · Jun 2026
Rejoni is focused on developing and commercializing gynecological products built on proprietary biomaterials, with its lead investigational product the Juveena Hydrogel System.

The product is investigational and pending U.S. FDA approval and is not available for sale. Rejoni is clinical-stage and plans to scale manufacturing, supply operations, and market-access and physician/patient engagement in preparation for commercial launch. The company was founded in June 2020 in Bedford, MA; Amar Sawhney is founder and chairman and John Nealon is CEO. The recent $25 million financing will support these commercialization and regulatory preparations.
- Voxmind
Led · Seed · May 2026
Voxmind has developed a patent-pending phoneme-frequency extraction engine that analyses the biomechanics of the human vocal tract to deliver language-agnostic voice authentication and deepfake detection. The technology achieves 99.8% deepfake detection accuracy in under three seconds and runs in under 500MB of runtime memory with no GPU or cloud connectivity required. Its architecture supports on-device OEM SDKs, platform-native integrations for CCaaS and UCaaS operators, and a cloud API for enterprise deployments. The company has already secured an OEM agreement to embed its voice biometric SDK into enterprise IP phone hardware and reports commercial pipeline activity across community banking in the U.S., telecoms in Europe, and partnership conversations with global IT services and contact centre operators. Founded in January 2024, Voxmind positions its physics-based, edge-capable approach as a response to recent exits of major cloud voice biometric services by large cloud providers.
