Our Story

After 15 years working with startups, I've realized that the return on investment for C-level executives, VPs, heads, and other leadership positions hinges on the company's growth stage. Often, only a fraction of our time is spent on tasks that add real value. Meanwhile, a significant portion is devoted to tasks that could be handled by junior staff at a lower cost. This mismatch not only reduces headcount ROI but also impacts leadership satisfaction. By leveraging fractional services, companies can optimize their resources, focus on high-impact activities, and boost overall efficiency and morale.

To address these challenges, we created Leftorn, a collective of experts dedicated to supporting companies. Our diverse group ensures comprehensive assistance for any department and need. With a wide range of specialities and industries, we provide a holistic approach and  support for your business, optimising resources and enhancing efficiency.
