Building the Future of Private Communication

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.

First Native C Implementation of SMP IT and More Systems Made in Germany

SimpleGo by IT and More Systems

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.

Company Formation in Progress - 2026

SimpleGo UG (haftungsbeschränkt) is being founded this year

SimpleGo is currently operated by Sascha Dämgen under IT and More Systems (Einzelunternehmen), Recklinghausen, NRW. The dedicated company SimpleGo UG (haftungsbeschränkt) is actively being incorporated in 2026. The existing business will be folded into the new entity, providing the legal and organizational foundation for hardware production, partnership agreements, the Kickstarter campaign, and long-term ecosystem development.

All development remains fully open source. The company exists to manufacture, distribute, and support the hardware - not to change what SimpleGo is.

A Verified Whitespace in Hardware Security

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. The maximum feature overlap found in any single device is three out of six.

of SimpleX Protocol

No Device Has Ever Combined All Six

5-Layer Per-Message Encryption

Five cryptographically independent envelopes around every message: Double Ratchet E2E with post-quantum sntrup761 hybrid, per-queue NaCl cryptobox, server-to-recipient re-encryption, and TLS 1.3 transport with key hash pinning. No other device implements this architecture. The maximum found across 70+ analyzed products was two layers.

Bare-Metal Firmware

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. Approximately 50,000 lines of auditable C code versus 50 million lines in a smartphone. The entire firmware compiles from source in under 60 seconds.

No Baseband Processor

The device has no cellular modem whatsoever - not isolated, not firewalled, simply not present. The ESP32-S3 and STM32U5 microcontrollers are not phones. The BASECOMP study found 29 critical vulnerabilities in Samsung and MediaTek baseband firmware. SimpleGo eliminates this entire attack surface by hardware design.

No Persistent Identity

SimpleX Protocol uses no user identifiers whatsoever. No phone numbers, no usernames, no public keys as permanent identity. Contacts connect through one-time invitation links that are discarded after use. A factory reset produces a device with zero mathematical relationship to the original. There is nothing to subpoena.

Triple-Vendor Secure Elements

Three secure element chips from three different manufacturers: Microchip ATECC608B, Infineon OPTIGA Trust M, and NXP SE050. This concept has never appeared in any commercial product, military device, academic prototype, or published patent. The 2024 Eucleak attack proved that even EAL5+-certified chips from a single vendor can harbor critical flaws for 14 years.

Fully Open Source

Every line of firmware is published under AGPL-3.0. Every PCB trace is documented under CERN-OHL-W-2.0. No binary blobs. No proprietary modules. The entire device can be built from source by anyone with a compiler and a soldering iron. Security claims that cannot be independently verified are marketing, not engineering.

Three Security Tiers, One Codebase

Different threat models require different levels of protection. The same firmware runs across all tiers, with security features activating based on detected hardware capabilities. All devices are made in Germany with no component quality compromises.

Model 1 "Maker"
€100 - 500

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.

Model 3 "Vault"
€1,500 - 15,000

Full specification with STM32U5A9 processor, triple-vendor secure elements, active tamper detection with sub-microsecond zeroization, and hand-assembled luxury construction. For high-value targets and sovereign-grade security requirements.

Funding Model

SimpleGo follows a proven startup funding approach: clean investment structures without control strings, combined with community-driven crowdfunding.

YC SAFE Model

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 legal requirements.

This is the proven model used by successful open-source security companies. Clean investment structures without control strings, preserving the project's independence and engineering integrity.

partnership@simplego.dev

Kickstarter Campaign

The Model 1 "Maker" device is an ideal Kickstarter candidate: dedicated open-source hardware, a strong niche community, and a clear value proposition. Flipper Zero demonstrated the viability of this path by raising $4.8M+ for a similar hardware concept targeting the same technically-minded audience.

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 funding.

Campaign in Preparation

Distribution Partnerships

We are open to distribution partnerships with privacy-focused retailers, security consultancies, and enterprise resellers. Wholesale pricing is available for qualified partners. White-label and OEM configurations are possible for Model 2 and Model 3 tiers with custom firmware branding and support agreements.

About SimpleGo

SimpleGo is an independent project by IT and More Systems, a German company. We are building the world's first dedicated secure communication devices that implement the SimpleX Messaging Protocol natively on embedded hardware - the first native C implementation of SMP to ever exist.

Our devices operate without smartphones, without cellular baseband processors, and without persistent user identities. The firmware runs on bare metal, the cryptography implements the complete 5-layer per-message encryption architecture, and every component is selected for maximum security without cost compromise. All devices are engineered and assembled in Germany.

The project is fully open source under AGPL-3.0 (software) and CERN-OHL-W-2.0 (hardware). SimpleGo uses the open-source SimpleX Messaging Protocol for interoperable, metadata-free message delivery.

SimpleGo is not a subsidiary or affiliate of SimpleX Chat Ltd. The SimpleX name and protocol are used under open-source license terms (AGPL-3.0) for interoperability purposes.

Ready to Build Together

Whether you are an investor, a distributor, a researcher, or just someone who believes in genuinely private communication - there is a place for you in this project.
