SimpleGo is transitioning from an independent engineering project into a dedicated company. We are building the world's first hardware-secured messaging devices and invite strategic partners, investors, and collaborators to join us on this journey.
SimpleGo is being established as a German limited liability company to provide the legal and organizational foundation for hardware production, partnership agreements, crowdfunding campaigns, and long-term development of the SimpleGo ecosystem.
What started as an engineering challenge has become a viable product with real market demand. The formation of SimpleGo UG creates the structure needed to take SimpleGo from a working prototype to a commercially available product line, starting with our Kickstarter campaign.
The company will be headquartered in North Rhine-Westphalia, Germany, and will operate under German corporate governance standards. All development remains fully open source. The company exists to manufacture, distribute, and support the hardware that runs our open firmware.
SimpleGo has earned the official support of SimpleX and its founder Evgeny Poberezkin. As the first-ever third-party implementation of the SimpleX Messaging Protocol outside the original Haskell codebase, SimpleGo represents a milestone in the SimpleX ecosystem. The SimpleX team has provided direct technical guidance, protocol-level support, and has publicly endorsed the project.
Partnership discussions between SimpleGo and SimpleX are ongoing and progressing positively. The shared vision of decentralized, metadata-free communication drives both projects, and the possibility of deeper collaboration reflects the natural alignment between a protocol-defining software platform and its first dedicated hardware implementation.
SimpleGo has been invited to participate in the SimpleX Network Foundation Consortium, positioning the project at the center of the emerging SimpleX hardware and application ecosystem.
After exhaustive research across more than 70 devices spanning consumer, military, criminal, and DIY domains, SimpleGo occupies a design space that no existing product, prototype, or published concept has ever addressed.
Four cryptographically independent encryption envelopes around every single message: Double Ratchet E2E, per-queue NaCl, server-to-recipient NaCl, and onion forwarding layer. No other device implements this.
No Android. No Linux. No smartphone OS. Pure C firmware running directly on FreeRTOS with complete control over every byte of memory and every instruction executed.
The device has no cellular modem. No secondary CPU running proprietary firmware with known vulnerabilities. The entire telecom attack surface is eliminated by hardware design.
SimpleX Protocol uses no user identifiers whatsoever. No phone numbers, no usernames, no public keys as identity. Contacts connect through one-time invitation links that are discarded after use.
Three secure element chips from three different manufacturers. If one vendor's silicon is compromised, the other two maintain protection. This concept appears in no existing device, patent, or academic paper.
Every line of firmware code is public under AGPL-3.0. Every PCB trace is documented under CERN-OHL-W-2.0. Security through transparency, not obscurity. Trust is earned, not promised.
Different threat models require different levels of protection. The same firmware runs across all tiers. Made in Germany with no compromises on component quality.
DIY-friendly development board based on ESP32-S3. QWERTY keyboard, 2.8" display, WiFi connectivity. Perfect for makers, developers, and the privacy-conscious community. Available as kit or pre-assembled.
Custom PCB with STM32U585 main processor, ESP32-C6 WiFi module, single secure element, tamper mesh, and premium AMOLED display. CNC-machined aluminum case. For professionals and organizations requiring verified security.
Full specification with STM32U5A9 processor, triple-vendor secure elements, active tamper detection with zeroization, TEMPEST considerations, and hand-assembled luxury construction. For high-value targets and sovereign-grade security.
SimpleGo follows the proven startup funding approach that has worked for the SimpleX project itself: clean investment structures without control strings, combined with community-driven crowdfunding.
We follow the Y Combinator Simple Agreement for Future Equity model for strategic investments. Money now, equity later at a capped valuation. No board seats demanded, no veto rights, no reporting obligations beyond what is legally required.
This is the same model used by SimpleX itself, which received investment from Jack Dorsey and Ethereum Foundation founder Vitalik Buterin, both without strings attached.

The Model 1 “Maker” device is an ideal Kickstarter candidate: dedicated hardware, open source, strong niche community, and a clear value proposition. Flipper Zero demonstrated the viability of this path with $4.8M+ raised for a similar hardware concept.
The campaign will offer early-bird pricing on Model 1 kits and pre-assembled units, with stretch goals for advanced features and Model 2 development.
Campaign in Preparation
We are open to distribution partnerships with privacy-focused retailers, security consultancies, and enterprise resellers. Wholesale pricing available for qualified partners. White-label and OEM configurations possible for Model 2 and Model 3 tiers.

Academic institutions, independent security researchers, and government testing labs are invited to evaluate SimpleGo firmware and hardware designs. We welcome responsible disclosure, penetration testing, and formal verification efforts. Bug bounty program planned post-launch.

info@simplego.devSimpleGo is an independent project transitioning into SimpleGo UG (haftungsbeschränkt), a German limited liability company. We are building the world's first dedicated secure communication devices that implement the SimpleX Messaging Protocol natively on embedded hardware.
Our devices operate without smartphones, without cellular baseband processors, and without persistent user identities. The firmware runs on bare metal, the cryptography uses 4-layer per-message encryption, and every component is selected for maximum security without cost compromise.
The project is fully open source under AGPL-3.0 (software) and CERN-OHL-W-2.0 (hardware). SimpleGo is officially supported by the SimpleX project and participates in the SimpleX Network Foundation Consortium.
SimpleGo is not a subsidiary or affiliate of SimpleX Chat Ltd. The SimpleX name and protocol are used under open-source license terms for interoperability purposes. The partnership between both projects is based on shared values: privacy, transparency, and engineering integrity.
SimpleGo UG (haftungsbeschränkt) is a German limited liability company being formed in 2026 to manufacture and distribute dedicated secure communication hardware. SimpleGo builds the world's first devices implementing the SimpleX Messaging Protocol natively on embedded microcontrollers. The project is officially supported by SimpleX and its founder Evgeny Poberezkin. SimpleGo is the first-ever third-party implementation of the SimpleX Messaging Protocol outside the original Haskell codebase.
SimpleGo combines six security features never found together in any commercial product, military device, academic prototype, or published concept: 4-layer per-message encryption, bare-metal firmware, no baseband processor, no persistent identity, triple-vendor secure elements, and fully open source code. After exhaustive research across more than 70 devices, the maximum feature overlap found in any single device is three out of six.
The encrypted phone market is projected to reach $8.36 billion by 2034. SimpleGo offers three hardware tiers: Model 1 Maker (EUR 100-500 DIY), Model 2 Shield (EUR 500-1500 professional), and Model 3 Vault (EUR 1500-15000 sovereign-grade). All devices are engineered and assembled in Germany.
Investment follows the YC SAFE model. Kickstarter campaign in preparation. Distribution, OEM, and security research partnerships welcome.
