I work with a select number of comapnies as a business growth mentor both as a paid mentor and pro-bono through the Imperial College Venture Mentoring Scheme (IVMS).
IVMS mentoring has to go through the IVMS team. If you are eligible, you will know!
Paid mentoring can be bespoke, but usually works as 2x 2hr sessions per month either in person or remotely. It can be more or less, depending on the situation. I only work with 4-5 companies at any one time and only work with ambitous, driven people who really want to grow their businesses. To find out more about what I do and availability email firstname.lastname@example.org with ‘mentoring’ as the subject.
