Explore Learning, the UK company with multiple English and maths tuition centres, led by founder Bill Mills, was sold to Graphite Capital. The controlling shareholding was acquired from a group of investors including the Spectrum Venture Management Fund and Wittington Investments Limited. Bill Mills and the senior management team re-invested the majority of their stake in the company. Corbett Keeling has worked with Bill Mills, who set up Explore Learning in 2001, over many years and advised him throughout the sale process and particularly on the terms of his reinvestment in the business.
