Free call: 30 minutes about your goals and challenges. No commitment and no sales pitch. 2. Diagnosis: A review of systems, processes, costs and the team. You know where you stand and what's blocking growth. 3. Plan with KPIs: Concrete actions, budget and the metrics the board will use to judge success. 4. Delivery: I run the rollout, keep vendors and deadlines in check, and report progress regularly. Formats: Project with a clear scope; Ongoing advisory support; Interim or part-time CIO / CTO. ## FAQ - **How much does it cost?** It depends on the format: projects are priced for the full scope, while ongoing support and the fractional CIO role are billed monthly. I bill per working day, not for individual hours. The first 30-minute call is free. - **How is a fractional CIO different from hiring an IT director?** You get the same executive experience, but only as much of it as the company needs – without the cost of a full-time hire or months of recruitment. We can start with a few days a month. - **Is AI safe for my customers’ data?** Every rollout starts with rules: what data can reach the model, who has access, and how we meet GDPR and EU AI Act requirements. We do not start a pilot without them. - **Do you only work with large retail chains?** No, I work with any organisation that wants to use my services. Company size does not matter. - **Do you deliver projects alone or with a team?** I run the project and own the business goal, and for each specific task I bring in proven specialists and vendors from my partner network. ## Contact - Email: info@idu.net.pl - Phone: +48 515 177 761 - Address: ul.
