Services

What we do and what you get

Seven services in two fields. Each one states who it is for, which problem it solves and what you hold in your hands at the end.

01 / Web & Growth

Web & Growth

Websites, apps and marketing for businesses that live on guests, enquiries and bookings.

01

Websites

A site that says clearly what you do and brings in enquiries, not just visits.

Typical duration
3 to 5 weeks
Enquire about this service

Who it is for

Restaurants, apartments and hotels, trades and local brands whose website is the first impression and the main enquiry channel.

  • Croatian and English versions with correct hreflang
  • Technical SEO: speed, structured data, sitemap, Search Console
  • Spam-protected contact form and cookieless analytics

02

Web apps and PWAs

When no off-the-shelf tool fits your process, we build the system that does.

Price
from €5,000
Typical duration
6 to 12 weeks
Enquire about this service

Who it is for

Companies running operations through spreadsheets, chats and paper, and teams with an idea for their own digital product.

The problem it solves

Data lives in five places, the same thing is typed more than once, and nobody sees the whole picture. Packaged tools ask you to bend your process to them.

What you get

  • A written specification and clickable prototype before the first line of code
  • A Next.js application on PostgreSQL (Supabase)
  • PWA: installable on a phone, usable on a weak connection
  • Authentication, roles and data backups
  • A staging environment, documentation and the source code

Process

  1. 1Process mapping and specification
  2. 2Prototype and scope sign-off
  3. 3Phased build with a weekly review
  4. 4Testing with your users
  5. 5Production, training and support

03

Performance marketing

Monthly channel management with a plan at the start and numbers at the end of the month.

Price
On request
Typical duration
Monthly engagement, 3 months minimum
Enquire about this service

Who it is for

Hospitality and local brands that want a steady presence but have no one to run it every day.

The problem it solves

Posts go out when someone has time, ads spend budget without measurement, and the Google profile shows last year's opening hours.

What you get

  • A marketing plan with goals, channels and a calendar
  • Instagram and Facebook management
  • SEO with Google Search Console and a maintained Google Business Profile
  • Meta and Google ads within an agreed budget
  • A monthly report: what was done, what it brought, what comes next

Process

  1. 1Review of the current state and accesses
  2. 2Plan and goals for the first three months
  3. 3Monthly execution against the calendar
  4. 4Report and plan adjustment

02 / Infrastructure & Security

Infrastructure & Security

IT and OT environments for companies where an hour of downtime costs more than the project.

04

IT infrastructure and support

Servers, network, user accounts and a team that picks up when something stops.

Price
On request
Typical duration
Assessment 1 to 2 weeks, execution per plan
Enquire about this service

Who it is for

Companies from a dozen to a few hundred users with no IT department, or with one overloaded administrator.

The problem it solves

Infrastructure grew without a plan: nobody knows what runs on which server, backups are untested, and support requests arrive as chat messages.

What you get

  • An asset inventory and documentation of the real state
  • Proxmox virtualisation and a Windows domain (Active Directory)
  • Microsoft 365, SharePoint and tidy access rights
  • An IT ticketing system (SharePoint and Power Automate)
  • Backups with a tested restore

Process

  1. 1On-site assessment
  2. 2A prioritised plan with risk estimates
  3. 3Execution in agreed maintenance windows
  4. 4Documentation and handover
  5. 5Support as agreed

05

Network segmentation (IT/OT)

Office networks and control systems should not share the same traffic.

Price
On request
Typical duration
4 to 10 weeks, depending on the number of sites
Enquire about this service

Who it is for

Maritime companies, industrial plants and logistics: anywhere machines, sensors or control systems are on the network.

The problem it solves

In a flat network an infected office PC can reach the control systems. One IT incident then becomes an operational stop.

What you get

  • An IT and OT asset inventory with the data flows between them
  • Zoning (VLANs) with least-privilege rules
  • Controlled crossings between zones and secure remote access
  • Traffic control on bandwidth-limited links, including satellite
  • Documentation an auditor and your IT team can verify

Process

  1. 1Asset and flow inventory
  2. 2Zone and rule design
  3. 3Phased rollout without stopping operations
  4. 4Rule verification and documentation

06

NIS2 readiness

From a gap list to measures that actually work, without scare tactics or paperwork for its own sake.

Price
On request
Typical duration
Gap analysis 2 to 4 weeks, implementation per plan
Enquire about this service

Who it is for

Companies in scope of the Croatian Cybersecurity Act, or bound to compliance by a contract with a larger partner.

The problem it solves

The Croatian Cybersecurity Act transposes the NIS2 Directive and requires risk management, incident handling and management accountability. Most companies do not know where to start or what is proportionate for them.

What you get

  • A gap analysis against the Act and the NIS2 Directive
  • A remediation plan with priorities, deadlines and owners
  • Implementation of technical measures: segmentation, access, backups, monitoring
  • Incident and business continuity procedures, written for people
  • For shipping: alignment with IACS UR E26 and E27

Process

  1. 1Scope and obligations
  2. 2Gap analysis
  3. 3Remediation plan
  4. 4Implementation and evidence
  5. 5Periodic review

Note: NIS2 readiness is technical and organisational work, not legal advice. Whether you are in scope is determined under the Croatian Cybersecurity Act.

07

Monitoring and automation

So you learn about a fault from an alert, not from a user.

Price
On request
Typical duration
2 to 6 weeks
Enquire about this service

Who it is for

Companies with field equipment, sensors or processes that are tracked by hand today.

The problem it solves

The data exists, but nobody looks at it until something goes wrong. Reports are assembled by hand and the on-call person is phoned until someone answers.

What you get

  • Sensor and system data collected in one place
  • Power BI reports that refresh themselves
  • Automated alerts with thresholds you define
  • Call escalation: the system rings on-call staff in order until someone answers
  • Automation of repetitive steps in Power Automate

Process

  1. 1What is measured and who needs to know
  2. 2Connecting data sources
  3. 3Reports and alert thresholds
  4. 4Trial run and tuning
