Silent Key Technologies builds privacy, security and AI software in Riyadh. We are raising a USD 500,000 to 1,000,000 pre-seed round.
Every answer on the market today asks you to trust whoever holds your key. We build systems where the owner keeps the key, only the minimum leaves, and every action leaves signed proof.
AI does the work on placeholders. Names, ID numbers and diagnoses are hidden before a prompt leaves the company and put back when the answer returns.
The whole application stack runs on the customer's own servers, inside the Kingdom, and the customer can count every connection it makes.
A vault opens to the right person only when the conditions its owner set are met: crypto inheritance without handing anyone the keys early.
Files are born encrypted, so destroying one means erasing its key. Every destruction issues a receipt anyone can verify offline.
| Product | What it does | Status |
|---|---|---|
| NOAI+ | Privacy gateway that lets a company use AI without sending personal data, in Arabic and English | Live gateway since 7 Oct 2026 |
| SilentBOX | Encrypted vault app; the passphrase never leaves the phone | Live on Google Play |
| BurnKey | Destroys data on command and issues a receipt verifiable offline | Live on Google Play |
| Kontra+ | Contract risk review for Gulf construction, hosted in Riyadh on SCCC | Live |
| SilentSpace | The application platform that never leaves the Kingdom, on the customer's own servers | Running demo, in build |
| Release engine | Conditional release by API for wallets, custodians and estate technology | Design stage |
The studio also ships TagTitan, SwiftPOD and Fontbench (live) and Jobsome and ModeGuard (in build). See the full portfolio.
An evaluator decides the fate of a key it never holds, with delivery and erasure as its two outcomes. One filing covers both the inheritance handover and verified destruction.
Routes what an encrypted vault shows by the outcome of authentication, so an unlock forced under duress opens decoy content and the real vault stays sealed.
| Line | Price | Basis |
|---|---|---|
| SilentSpace | Licence SAR 18,000, deployment and hardening SAR 55,000, compliance evidence pack SAR 40,000; then SAR 35,000 a year | SAR 113,000 first deployment |
| NOAI+ | Installed, supported company gateway, priced per company rather than per user | USD 300 a month, test price |
| Kontra+ | Construction contract risk review | SAR 2,400 per contract |
| Release engine | API per vault or per seat, white label inside partners, or a licence to the patent | Design stage |
The round completes what a regulated buyer needs before it can sign.
So a bank, hospital or ministry can contract with us and be invoiced.
A third party penetration test and cryptographic assessment, which turns architecture into evidence.
International filing for both applications inside the twelve month window.
A regulated buyer running SilentSpace or NOAI+ on its own servers, and the engineers to carry it.
Stated plainly. We have no paying customers yet and the studio is pre-revenue. Both patent applications are filed and not yet granted. Our compliance mappings are our own assessments, not accreditations. The release engine is at design stage and no licensee is signed. We use standard published cryptography and never homemade algorithms.
Ramzi Hobeishy has spent more than fourteen years leading programme and portfolio delivery across technology, construction and commercial ventures in Saudi Arabia, the Gulf, West Africa and the Levant. He designs and ships every Silent Key product, filed both patent applications, and works on Silent Key full time from November 2026.
