Engineering the Sovereign Enterprise. Software engineering, AI and systems integration
XSIS designs and builds software, AI and data platforms, and connects your ERP to banks, POS and third parties, with in-house and outsourced teams that stay to run what they build.
What we do
Six divisions and their capabilities, from strategy and AI to integrations, cloud and security.
Strategy & Consulting
We work with boards, executives and public ministries to plan enterprise architecture, lead digital transformation and put regulatory governance in place before any code is written.
AI & Data
We engineer sovereign LLM platforms, multi-agent systems (MCP, A2A), large quantitative models and petabyte-scale lakehouses that turn institutional data into autonomous execution.
Software Engineering
We design, build and modernise high-concurrency enterprise software, composable web and mobile platforms, mainframe-to-cloud migrations, and 3D industrial and urban digital twins.
Enterprises & Integrations
Integration is a dedicated discipline at XSIS: connecting Tier-1 ERPs (SAP, Oracle, Odoo) directly to banks (ISO 20022), national tax authorities (ZATCA, PINT-AE, ViDA), payment rails (AP2) and POS networks.
Cloud & Infrastructure
We architect multi-cloud and sovereign cloud environments without lock-in, run private GPU inference clusters, build Kubernetes internal developer platforms and optimise cloud and AI token spend.
Cyber & Quantum
Backed by the cryptographic engineering heritage of our parent group, we protect critical infrastructure through NIST post-quantum migration, AI agent security, zero trust and round-the-clock SOC and OT defence.
Fintech is where we go deepest
Banking, payments, lending, wealth, insurance and digital wallets run on systems that must be right every time. We build those systems and the connections between them, with the regulation in mind from the first design.
Banking
Digital banking channels, core banking extensions and bank connectivity for corporate clients.
Payments
Gateway and acquirer integrations, payment orchestration, settlement and reconciliation.
Lending
Origination, decisioning and servicing platforms, with explainable credit models.
How we start
Start with a readiness review, then the track that fits: clear requirements, a blueprint first, or a live system to rescue.
- Proposal: within 3–5 business days
Track A: scope-ready
For a defined scope, a tender RFP or technical specifications. We begin with architecture validation at no cost, then issue a binding, fixed-scope proposal and mobilise the team.
- Tier 1: 1–2 weeks
Track B: Blueprint Studio
For a clear business goal without technical specifications. Paid workshops turn it into a ready-to-build blueprint, in one of three tiers.
- Diagnostic: 1–2 weeks
Track C: Brownfield Diagnostic Bridge
For a live system that is failing, undocumented or needs integration. Before anyone fixes a price, our principal engineers look under the hood: the code, the ERP and database, the APIs and the security.
Accountable engineering, proven in production
The people behind XSIS, the experience they bring, and the results our clients measured.
- engineers, architects and specialists
- 60+ people
- of executive technology and systems leadership
- 18+ years
- countries our team works from
- 6
- to respond to a critical (P1) incident, any hour of any day
- under15 minutes
Over the past 18+ years — from the early days of cloud computing to today’s era of sovereign AI and post-quantum security — one truth has never changed: enterprises do not need more slide decks or disconnected code. They need accountable engineering partners who understand how infrastructure, core ERPs, banking rails, and intelligence work together as one resilient system.
Case studies
- 99.4% straight-through processing on automated camt.053 bank statement reconciliation
Automated ISO 20022 host-to-host treasury and real-time tax clearance engine
How a Tier-1 GCC commercial bank connected SAP S/4HANA to its banking rails over ISO 20022 and cleared every e-invoice with ZATCA and PINT-AE in real time.
- under 250 ms SKU inventory sync across 800+ POS terminals and the digital storefronts
Real-time POS-to-ERP synchronisation and a high-concurrency omnichannel commerce engine
How a multi-brand GCC retail and mall conglomerate replaced overnight batch syncs with real-time stock, sales and settlement across its stores and online channels.
- 52% lower monthly AI token and GPU inference spend, through semantic caching and small-model routing
Air-gapped sovereign LLM platform, MCP multi-agent automation and token FinOps
How a regulated European and MENA financial institution automated bilingual KYC and compliance work on private language models and cut its AI inference spend.

Questions clients ask first
Who is XSIS?
XSIS is KONG GROUP’s technology company. We design, build, integrate and run software for enterprises: AI and data, custom software, web and mobile, cloud, and the integrations that connect ERP systems to banks, POS and third parties. Fintech is our lead industry. We deliver through our own in-house engineers and vetted outsourced teams, under one set of standards.
How do you estimate cost?
We estimate from the scope, not from a rate card. After a first conversation we break the work into parts, size each one and write down the assumptions behind the estimate. The main drivers are the number of systems and integrations, the state of your data, security and regulatory requirements, the testing needed and the seniority of the team. You receive a written estimate with options, so you can choose what to do first. You see the price and the timeline before we start.
Who owns the code and the work you produce?
Intellectual property in the work we build for you is yours from the first commit — no assignment step at the end. That covers the custom code, documentation and other deliverables made for you. Anything we bring that existed before, such as internal tools or libraries, stays ours, and you receive a licence to use it in your systems. Open-source components keep their own licences, and we list them for you.
How do you protect our systems, code and data?
Access is granted per person, limited to what each role needs, and removed when that person leaves the project. We work in your repositories and environments if you prefer, use multi-factor authentication, and keep secrets in a vault, never in code. Code is reviewed before it is merged, dependencies are scanned, and production data is not copied into test environments without masking. We agree these controls with your security team at the start.
How soon can work start?
It depends on the team you need and on what has to be in place first: the contract, access to your systems, security reviews and, for integrations, your partners’ test environments. We tell you what we need from you and when, and confirm a start date in the proposal. Discovery work can often begin while access is being arranged.
