Description

Clave Mayor is a prominent independent venture capital and private equity firm based in Pamplona, Spain, with a significant presence in the Spanish investment landscape.

As one of Spain's leading independent managers, Clave Mayor oversees more than 300 million euros in assets under management, deployed through a diverse portfolio of funds tailored to different investment profiles and growth stages. Their strategic approach positions them as a key player in supporting both nascent and scaling enterprises within the Iberian Peninsula.

The firm's investment strategy spans seed, early-stage, and growth equity, focusing on sectors critical to technological advancement and economic development. These include Biotechnology, Information and Communication Technologies (ICT), Industry 4.0, Renewable Energy, FoodTech, and Health. Clave Mayor is particularly noted for its specialized initiatives, such as its collaboration with the Polytechnic University of Valencia.

For growth-stage companies, where the firm often leads or co-leads larger rounds, the initial investment can extend significantly. For instance, their Clave Mayor FCR IV fund, with a target size of €50 million, is designed to support more mature companies, indicating a capacity for larger first cheques. Based on their fund structures and reported investments, a typical first cheque for growth-stage companies can reach up to €5,000,000, reflecting their capacity to support companies through multiple funding rounds.
