Monty Ditibane is one of the guests attending this year’s CEOSleepout happening at Liliesleaf farm in Johannesburg on Wednesday 11 July 2018.

It will be Sifisile Ngwenya's CEOSleepout event and she’s bracing for the freezing cold highveld weather.

Chemserve's Hugo Basson, a trained scientist with an MBA who has spent most of his career in management, is a reflective leader as you'll hear in this episode of the CEO SleepOut. Feedback from colleagues and staff ahead of the event has been instructive - ranging from advice on how to keep warm through to newfound respect and pride. His unusual observations include an appreciation in how a younger generation of employees put far more credence on an organisation's culture - and whether or not it is serious about contributing to broader society.

Widely travelled, Harvard educated James Donald is an unlikely candidate for the CEO post at an idealistic non profit. But listening to this interview you'll quickly realise why he's all-in at the Tomorrow Trust, which he joined in March as CEO. Simply inspirational.

Insightful comments from Costa Diavostos, CEO of security company Bidvest Protea Coin, a business whose executives appreciate the powerful impact of their actions on front-line staff.

Liane McGowan, who is responsible for the operational side of the CEO SleepOut Movement, gives us an update on South Africa's largest charity fund-raising project - and a reminder of the event's major beneficiaries and their close links to patron Makaziwe Mandela's father, the nation's iconic Madiba.

Using international measures for the Social Return on Investment, IQ Business Group has quantified that in its three years thus far, the project's total impact has been four times the R52.7m distributed to beneficiaries by the CEO SleepOut. Stephen Smith provides the hard numbers - and throws out challenges to the top team at companies which are consistently admired for their social conscience.

Back in 1980 when he was a student leader in his native Korea, Samsung Electronics CEO and President Sung Yoon got to hear about Nelson Mandela. And on the 11th July he intends honouring the centenary of South Africa's icon by joining members of his executive team at Liliesleaf for the annual CEO SleepOut. He explains why in this interview with Biznews.com's Alec Hogg.

Chief Risk Officer of the IDC, Phakamile Mainganya, explains how the alignment between the value of the CEO SleepOut movement and those held by Nelson Mandela motivates his organisation to lend its full support to the initiative. In this interview he also shares how the IDC's top executives are keen to use the occasion to engage with private - including his former boss, Nedbank CEO Mike Brown.

After a quarter century of funding and supporting women entrepreneurs, WDB Investment Holdings has been a powerful force for good in South Africa. In this interview its long-time chief executive Faith Khanyile explains why WDB is such a big supporter of the CEO SleepOut movement and lays down challenges to some of her peers.
