Strategie Retencji

Your Blueprint for Profitable Scaling
Is your company stuck in the trap of constantly acquiring new customers whose costs are rising and loyalty is falling? It's time to stop relying solely on one-time transactions. Our answer is a Retention Strategy. This is a comprehensive plan that will transform your business into a predictable profit-generating machine.
This is not just another generic strategy. It's a precise blueprint for unlocking hidden potential in your customer base, ensuring sustainable and profitable growth in a volatile market environment.
Who is this service for?
For owners, boards, and directors who are ready for a fundamental change in their approach to e-commerce growth. Ideal if you are looking for a comprehensive plan for long-term, profitable development that will transform one-time transactions into a stable source of profit.
Goal and Result
We will develop and implement your proprietary Value Growth & Acceleration Protocol (V-GAP). This is a proven, four-stage methodology that precisely identifies "Value Gaps", designs a personalized strategy, accelerates customer value growth at every stage of their lifecycle, and implements a results control system. You will receive a comprehensive business architecture and a 6-12 month roadmap that will ensure measurable and predictable growth.
Important distinction
This is a flagship, comprehensive strategic project that leads to a fundamental change in the business model, requiring your commitment.
Training, Workshops
Strengthen your team with competencies enabling them to work on Customer Lifetime Value (CLV)
In a world where acquisition costs are rising and loyalty is falling, the key to profitable growth lies in existing customers. My practical training sessions will equip your team with the competencies and tools to unleash this potential and drive the predictable development of your e-commerce.
Who is this service for?
For e-commerce leaders and teams striving for independent, profitable scaling. This is an ideal option when you need to equip your team with practical skills in building customer value, streamline internal retention processes, or ensure that planned CLV strategies are successfully implemented and yield measurable results.
Goal and Results
I conduct intensive workshops and training sessions that provide practical tools and proven frameworks (e.g., Retention Profitability Engine - RPE). Through them, your team will learn how to independently:
Precisely diagnose value gaps and build initiatives that will develop e-commerce.
Design and implement effective Marketing Automation scenarios.
Build lasting customer loyalty and maximize their long-term value.
Measure the effectiveness of actions and optimize CLV processes. This is knowledge that immediately translates into results.
Important distinction
Training focuses on developing internal competencies and transferring practical knowledge to your team. It does not include comprehensive strategy creation from scratch or ongoing operational supervision of implementation (these aspects are carried out as part of the Retention Strategy service or dedicated Consultations).
