Nairobi ยท since 2022
Software, systems and infrastructure, built and maintained by one team.
Sayari Cyber builds and runs the technology Kenyan organisations depend on. Clients come to us because they would rather brief one team than coordinate four vendors.
Where do you start?
Pick the sentence that sounds like you.
Five very different buyers land on this page. Each of these goes straight to the page written for you.
I need a website built.
Marketing site, e-commerce or a portal
I need a system built.
Inventory, POS, school, clinic, HR
I need AI that actually ships.
Agents wired into what you already run
I need on-chain, done properly.
Contracts, provenance, settlement
I need infrastructure and GPU.
Networks, servers, clusters, cloud
I need IT support.
Helpdesk, monitoring, callouts, security
What we do
Three connected layers, fourteen services.
Software that runs the business, infrastructure that runs the software, and support that keeps both alive.
Build
Things we make for you
Web development
Marketing sites, e-commerce, portals and web apps that load fast on Kenyan networks.
Build / 02Software & systems
Custom internal systems: inventory, POS, HR, school and clinic management, integrations.
Build / 03Mobile apps
Android-first apps with offline support, M-Pesa payments and USSD/SMS fallbacks.
Build / 04AI agents & automation
Agents and automations wired into the systems you already run, with humans in the loop.
Build / 05Blockchain & Web3
Smart contracts, tokenisation, wallets and audited on-chain integrations.
Infrastructure
Things we install and configure
GPU clusters & on-prem AI
In-house AI compute: sizing, procurement, power and cooling, install, scheduling, handover.
Infrastructure / 02GPU optimisation
Kernel engineering and performance work: more throughput from the hardware you own.
Infrastructure / 03Networks & servers
Structured cabling, switching, Wi-Fi, firewalls, on-prem servers, virtualisation, backup.
Infrastructure / 04Cloud & DevOps
Cloud migration, containers, CI/CD, monitoring, cost control, hybrid on-prem setups.
Infrastructure / 05Hardware supply
Specification, sourcing and deployment of workstations, servers, GPUs and network kit.
Run
Things we keep working
Managed IT & support
Monthly support: helpdesk, patching, monitoring, asset register, on-site callouts.
Run / 02Cybersecurity
Assessments, hardening, email security, backup and recovery, staff awareness training.
Run / 03Data & analytics
Dashboards, reporting pipelines, data cleanup and warehousing on top of your systems.
Run / 04Training
Handover training for the systems we build, plus practical IT and AI-tool workshops.
Selected work
What it looks like when it is finished.
Stock and dispatch system for a regional distributor
Four branches on separate spreadsheets, month-end taking a week.
One day
Month-end close
On-premise AI cluster for a research institution
Research data that could not leave the country, on cloud GPU hours nobody could afford.
Overnight
Job turnaround
WhatsApp support agent for a service business
Two staff answering the same twelve questions all day, and nothing after hours.
Routine enquiries
Resolved without staff
The difference
Run your own AI, on your own hardware.
We specify the GPU rack and write the code that runs on it. Sizing, procurement, power and cooling, install, scheduling, model serving, and the kernel-level work that gets more throughput out of what you already own.
- Data that cannot legally leave the building.
- Predictable cost once utilisation is steady.
- No dependence on international bandwidth for inference.
- Hardware you own on the balance sheet.
How we work
Four steps, each with something you receive at the end of it.
Discover
A call, then a site visit or a workshop with the people doing the work. We would rather understand the problem than start quoting a solution.
You get
A written summary of the problem and the options.
Specify
Scope, architecture, timeline and a fixed quote. Detailed enough that you could take it to another vendor and get a comparable price.
You get
A proposal you could hand to another vendor.
Build
Short cycles with a demo at the end of each one. You see working software or installed hardware, not a status percentage.
You get
Working software or installed hardware you can check.
Support
Training, documentation and credential handover, then a care plan if you want one. Support is the product, not an upsell.
You get
Ownership, and a support contract.
In their words
What clients say.
“The month-end reconciliation used to hold up everything else. Now it is a morning's work and the numbers agree the first time.”
“They told us not to buy two of the things we had budgeted for, and explained why. That is when we started trusting the rest of the advice.”
“Our researchers stopped shrinking their experiments to fit the queue. That is the whole point of owning the hardware.”
Who we serve
Five kinds of organisation, one delivery team.
Next step
Tell us what you're trying to build.
Most engagements start with a discovery call at no cost. You will have a written, fixed quote before any build work begins.
We reply to every enquiry within one working day.
