Soverli
ETH Zurich spin-off running an isolated, patent-pending sovereign OS layer alongside stock Android and iOS to protect high-risk communications without new hardware.

Soverli is a Zurich-based startup spun out of ETH Zurich, founded by CEO Ivan Puddu and CTO Moritz Schneider, that raised $2.6 million in pre-seed funding in December 2025 led by Founderful, with the ETH Zurich Foundation and Venture Kick also participating. The company’s technology, built on more than four years of ETH Zurich systems research, lets a sovereign operating system layer run in isolation alongside a device’s stock Android or iOS environment, without requiring new hardware.
The pitch is aimed at mission-critical communications: rather than issuing separate hardened devices to high-risk users, an organization can run an isolated, security-hardened environment on an employee’s existing phone for sensitive calls and messages. The company says the architecture is patent-pending and has cited a reduction in attack surface in public demonstrations, though that figure is a company claim relayed by press rather than an independently verified result.
Soverli reports public-sector pilots underway in emergency response and critical-infrastructure contexts, and plans to use its pre-seed funding to grow engineering, expand device support, and pursue OEM partnerships. As a pre-seed company with pilots still in progress rather than completed deployments, its real-world efficacy and commercial traction remain unproven.
Innovation Matrix Assessment
Converted over four years of ETH Zurich research into a patent-pending shipped layer and public-sector pilots within about a year of spinning out.
Running an isolated, hardened communications environment alongside stock Android/iOS gives security teams a way to protect high-risk communications without issuing new hardware.
Only pre-seed funding disclosed so far; pilots are described as underway rather than completed, with no named paying customers confirmed.
Running multiple isolated OS environments simultaneously on commodity hardware is a genuinely different architecture than existing hardened-phone or MDM approaches, though still unproven at scale.
The widely-cited attack-surface-reduction figure is a company claim relayed through a product demo and press coverage, not an independently tested result.
Demand for sovereign, surveillance-resistant communications for government and critical-infrastructure users is likely to grow as device-level threats increase.
Why CISOs Should Care
Gives security teams a way to run a hardened, isolated communications environment on employees' existing phones for high-risk use cases, without the cost and friction of issuing separate hardened devices.
What Makes It Different
Runs multiple operating system environments in isolation on a single device simultaneously, built on over four years of ETH Zurich research into phone-level isolation, rather than hardening or wrapping a single OS.
The Matrix Verdict
50/100 — INCREMENTAL INNOVATOR
A technically ambitious, research-backed architecture with public-sector pilots underway, landing as an Incremental Innovator: the isolation approach is a real structural departure from hardened-phone and MDM norms, but the company remains pre-seed with no completed deployments or independent testing yet.
Editorial Note: Claims vs. Verified Findings
The widely-cited attack-surface-reduction figure comes from a demo relayed by press as a company claim and has not been independently verified; the pilots described in coverage are reported as underway rather than completed.
