Who we are

A product company, not an agency.

We are a small software company in Ljubljana, Slovenia, part of the Elektronček Group. We rarely build apps to order. We pick an operation we understand, build the app for it on our own platform, put it in the stores, and keep it running. Golf courses, charter fleets, hotels, campsites, rentals, yachts. The people who use our apps every day tend to keep them for years, which is the measure we care about.

Our own products

Every app on this site is ours: designed, built, published and supported by us. There is no client behind it and no third-party product underneath it.

One platform underneath

Each product is really three parts on one platform: an end-user app, a staff app and a web portal that runs everything. Build one part well and the next product starts from there.

Built to run for years

Our systems stay up. Charter Manager App went through the whole 2025/26 season without a single outage, on Saturdays when fifty fleets turn their boats around at once.

The products

Nine apps.

Each product sells itself on its own site. Here they all are in one place.

Golf courses

GolfOS

Golf course operating software for the whole course: tee sheet, players, crew tasks, greenkeeping, carts.

Launching in Slovenia at the end of October 2026, with Golf Zveza Slovenije

The platform

One system, three parts. Every product is built the same way.

The modules are shared. The skin, the words and the workflow are the product.

1

The end-user app

For the player, the guest, the captain. Installs from the App Store, Google Play and Huawei AppGallery in about a minute. Notifications, content, bookings, check-in, reviews, chat, depending on the product.

2

The staff app

For the crew, the base, the greenkeepers. Big buttons, one tap per action, the state of everything readable at a glance. Built for people who work outdoors with their hands.

3

The portal

For the office. Content, users, bookings, notifications to one or to all, documents, analytics, Excel in and out. The place everything is set up and checked.

How the platform works

What comes next

Verticals we have already wireframed.

Because the platform is modular, a new vertical is mostly the skin, the words and a few modules. These are the ones we have wireframed and evaluated in depth, after real interest from the market. Each is a short step from the products above. If one of them is your business, talk to us.

✓ Villa and rental property manager, for owners and their guests
✓ Vacant property manager, for owners and the staff who look after empty homes
✓ Home owners association app, for the HOA and the unit owners
✓ Member app for clubs and associations, built on the Slovenian Business Club app
✓ Employee app: notifications, payroll information, education and tips
✓ Medical and spa manager: patient app and staff app in sync
✓ Travel agency tour app, for the agency and its travellers

Custom development

We are open to building a vertical with a partner who knows the operation, on our platform, with our modules. We do it rarely and only when it fits. Say what the operation is and we will tell you honestly whether it is a short step or a long one.

What we do not do

Agency work from a brief. We do not bid for app projects, and we do not build on other people’s platforms. That keeps us honest about what we can deliver and how fast.
