We have developed a free mentoring arrangement for those that wish to participate.  This is not limited to Greater London at all and is very much a nationwide activity.

There is no charge for this at all.  We simply wish for the London Cleantech Cluster platform to provide a basis to bring useful expertise to where it is needed.


Are you an experienced business person who would like to offer your services, initially at least on a pro bono basis, to a cleantech company that can benefit from your expertise?  This can naturally lead on to non-executive positions in the future, as well as provide support for companies at a strategically important time in their development.  Your expertise can be market specific or function specific, it does not matter.  There is significant demand for expertise in the cleantech sector.

Company looking for a mentor

Alternatively, are you a young company that would like to receive input from an experienced executive on a pro bono basis?  You might find that your senior management team is short of financial expertise, sales and marketing knowledge, presence or experience in a particular market or you simply need to have someone around to turn to who has done it all before successfully.  This can be very much the case if you are seeking to attract funding or a partner.

If you wish to be a pro bono mentor or you wish to have the significant benefits of a mentor to help you take your business forward, then please email with your details.
