"The team at Zephyr Acorn has been a terrific partner as we’ve grown the business. Beyond the capital, the team’s local presence in Nairobi and commitment to the market have made them indispensable for their experience and network, as well as their global investment footprint and business wisdom."

Elizabeth Rossiello, CEO-Founder, AZA

"Zephyr Acorn has been a truly effective advisor and sounding board for our executive team as we grew from a young start-up to a fast-paced growth company. We have really appreciated their depth of knowledge in the countries where we operate, especially their steady guidance on building steady business models in unsteady markets."

Fund Overview & Strategy

We are typically a company's first institutional capital and seek to invest across the following themes:

Digitization of traditional business models

Use of technology to enhance productivity and deliver cost-effective products and services

Innovation in the distribution or delivery of products and services

Inclusion of new customer segments with new products and services

We seek to partner with entrepreneurs who are passionate about a big idea, committed, adaptable, and coachable with strong execution skills and high integrity.

Post-investment, we actively support portfolio companies in areas such as finance, strategy, new market entry, and governance to help build the foundation for future growth.
