HelioOS releases privacy-first mobile OS and raises $25M to certify carriers and OEMs

Tech · 6 min read

HelioOS offers a modular permission model, on-device federated analytics, and a read-only system core that simplifies third-party audits. It supports mainstream app runtimes through a compatibility layer and provides OTA micro-updates to improve security without large firmware downloads.

The $25 million seed round was led by Meridian Ventures with strategic contributions from a regional OEM consortium. HelioOS will use the capital to complete compatibility certifications, expand security audits, and build a lightweight app marketplace with vetted apps.

Early reviews highlight the OS's fast update cadence and privacy defaults, but note potential friction for users dependent on Google Play services. HelioOS plans partnerships to provide optional service bridges and work with OEMs to pre-load compliant app alternatives.
