Business Mentoring for All: Closing the Advice Gap for Entrepreneurs Worldwide
Backed by data. Powered by people. Built for the global majority.
Our story
Micromentor was founded in response to a simple, global truth: starting and running a business is hard, and too often, entrepreneurs are offered generic training when what they really need is connection and the kind of practical, honest advice that comes from someone who’s been there. We’ve reimagined what entrepreneurial support can look like: not a course, but a conversation. One that’s easy to access, deeply human, and built around mutual respect. For over 15 years, Micromentor has supported entrepreneurs in under-resourced communities to grow their businesses by connecting them with experienced mentors - at no cost. Today, Micromentor is the world’s largest platform for business mentoring, connecting hundreds of thousands of entrepreneurs and mentors across the globe. And, we’re just getting started!
Our team
The Micromentor team is a global collective of dedicated individuals, working remotely to bring mentorship within everyone's reach. Our core team collaborates across various time zones, bringing a world of experiences and insights to the table. Alongside, we have smaller, localized teams focused on specific regions, ensuring our approach remains tailored and impactful. This blend of broad vision and local focus keeps us agile and deeply connected to the communities we serve.
