Why C-Squared

  • Impact & Focus: C-Squared is a strategic consultancy focused on making a real difference to our clients, and quickly. We operate only at C-level, advising CEOs, Chairmen and other top level executives.

  • Speed & Acceleration: Because we focus our work on a narrow band of sectors and companies, we have deep expertise that we can quickly translate into value for your business, helping you accelerate your own success.

  • Network & Experience: C-Squared can draw on a wide network of individuals and partner companies with specific subject matter expertise. If we don’t have the knowledge in-house, we will identify the experts that do. We will never take on a project or make a promise that we can’t deliver.

  • Thought partner and Advisor: We will engage with you on any questions concerning your wider business where we can add value as someone with the experience to challenge assumptions and validate ideas.

  • Passion & Commitment: We understand and share your passion for your business.

Your project, in good hands
