Software house
K.D. Vassiliou Group is a software house that also runs businesses of its own. We build, host and support software for companies in Cyprus and across Europe, and for our own businesses.
Software development company in Cyprus: Software built by people who run businesses.
We build the software a business runs on: point of sale, online stores, CRMs, internal tools and the connections between them. Then we host and support it. We also run businesses of our own, a gyros shop in Nicosia and a cleaning company that works across Cyprus, so we build for yours knowing what it means to depend on it.
We run businesses of our own, too

What we build
Software we build, host and support.
Software that runs the business. We build the systems your work happens in, not brochure sites. We connect them to the couriers, payment providers and suppliers you already use, and we stay on after launch to host and support them.
Illustration- 01
Custom software and platforms
One system for the work you now do in spreadsheets and separate tools, including CRMs, quoting and invoicing, customer portals and phone apps.
- 02
E-commerce and point of sale
An online store and a till that share the same products and the same stock, so the counter and the website always agree.
- 03
Integrations and automation
Couriers, payments, accounting and suppliers connected to your systems, so nobody retypes the same order twice.
- 04
AI engineering
AI that does one clear job inside the system you already run, with a person checking anything it is unsure about.
- 05
Infrastructure and hosting
Secure, backed-up hosting in Europe, on servers we run or on your own accounts, at a fixed monthly cost.
- 06
Digital marketing and SEO
The technical side of being found, with fast pages, correct markup and multilingual content that stays in step.
Selected work
Systems we built, and what they had to solve.
Every study is written from the source code, and describes the client without identifying them.

The businesses we run, and what they teach us.
We are a software house first. We also run businesses of our own, and they keep our software honest: a till that has to keep selling when the connection drops, end-of-day figures that have to match to the cent, bookings and invoices that have to agree. What we learn there goes into what we build for clients.

About Anchor -
Illustration
A venture our founder co-founded
Anchor: when life changes, the bank is there first.
Anchor helps retail and private banks notice the moments that change a customer's finances, such as buying a home, getting married or having a baby, using confirmed events in the bank's own data. It guides the customer through what the event means for their money, and alerts their relationship manager when the customer chooses to share. Our founder, Kypros Vassiliou, co-founded Anchor and is its technical lead.
Built for retail and private banks, starting in Luxembourg. It is designed to run on the bank's premises or in an EU cloud the bank controls, so client data stays in the bank. It is preparing its first bank pilot.

All productsHow we work
How a software project runs.
Technology built around the business, not the other way around. Four steps, and we stay on after the fourth: what we build, we also host and support.
- 01
Discovery
We map how the business actually runs today, including the spreadsheets and the workarounds.
- 02
Build
We build the system in small pieces you can start using before it is finished.
- 03
Integrate
We connect it to the couriers, payment providers and marketplaces you already depend on.
- 04
Host and support
We run it on your infrastructure or ours, as agreed, with backups, monitoring and someone to call.
Most of our case studies started as a conversation about a spreadsheet.

A note from the founder
Why software from operators works better.
“We run businesses of our own, so we know what it costs when the till stops or the figures don't add up. Before we write any code, we want to know how the work actually happens, including the spreadsheets and the workarounds. Then we build it in small pieces, host it, and stay to support it. If software is not the answer, we will tell you.”

Questions
Questions we are asked before we start.
If yours is not here, ask it when you write to us.
We reply within one working day
01Can you work with the systems we already use?
Usually that is the job. We connect what a business already pays for — couriers, payment providers, accounting and suppliers — so that work stops being retyped between them.
Integrations and automation02Can you move our existing records across?
Yes. We migrate off legacy systems with reconciliation: in one study the migration refuses to complete if the numbers disagree.
Read that study03What happens after launch?
We stay. What we build, we host and support: backups, health checks and uptime monitoring, with staging and approved production releases.
Infrastructure and hosting04Why are your clients not named?
Because we do not name a client, show their logo or publish their screenshots without written permission. Every study here describes the client without identifying them, and the same rule would cover your business.
How we treat client work05Do you work outside Cyprus?
Yes. We build for companies in Cyprus and across Europe.
