How to organize 3 acquired companies into one coherent website

The 5-second version

• Focus on user actions and goals rather than product features or company divisions when planning information architecture across acquired companies.
• Group homepage and navigation content by user goal to shift conversations from territorial product ownership to collaborative value creation.
• Develop taxonomy categories (like role, location, phase) that overlap fluidly so users can navigate intuitively without rigid silos.
• Test low-fidelity designs with actual users to validate labels, mental models, content hierarchy, and information density.
• Apply horizontal content thinking by placing critical components strategically across multiple pages rather than relying solely on single-page prominence.
