Prospective purchasers

Reason for sale

The founder, who does not work in the Company full time wishes to crystallise value built up in the business. He, together with his co-founder have built a substantial business, but one that would benefit from the additional resources that a larger company could offer.
Should a buyer so wish, the founder would welcome continuing to support the Business in an advisory capacity.
The current management team run the operations on a day-to-day basis and with some strategic oversight can run the business going forward.
