Innovation and entrepreneurship are the prerequisite to Africa's economic revival, and the millennials is the generation that will put the continent on a new growth trajectory, Mteto Nyati, MTN SA Chief Executive Officer told delegates at DEMO Africa conference held in Johannesburg.

The event is marketed as an annual Pan-African conference that provides a platform for African technology start-ups to pitch their ideas to both local and international investors in a bid to secure funding.

Mteto said while many countries in Europe are grappling with challenges posed by an ageing population, Africa is in a fortunate position to have population demographics where the bulk of the population is under the age of 25.

"The youth is the generation that will drive societal change," said Nyati. "This young population can be harnessed to be force for positive change and drivers of a radical economic upheaval. Many conglomerates and industries owe their origins to a younger members of the population, and we expect this younger generation to be at the forefront of change."

Nyati said organised business and conglomerates should play a role to uplift start-ups by driving programmes that bolster the growth of emerging enterprises and supporting initiatives that seek to foster the growth of the SME sector. "The development of emerging enterprises requires a concerted effort by all the role-players including established business, government and civil society. As corporates, we have to find ways of how we can leverage our brands, platforms and financial muscle to positively contribute to the growth of emerging enterprises."

He added that governments can play an important role by ensuring that they formulate a policy framework that creates an enabling environment that enables emerging businesses to thrive.

"We are encouraged by the number of innovative apps that have been unearthed by the App of the Year Awards, and one such innovative app is Domestly, a start-up that connects cleaning professionals directly to homeowners via mobile. The App of the Year competition has provided a platform that has also unearthed and given impetus to the growth and monetization of others apps, including the FNB Banking, Zapper, Vula Mobile, and PriceCheck," said Nyati.

He congratulated the aspiring entrepreneurs who attended the event, and reminded them that some of the Forbes 500 companies that are leaders in their respective sectors were once start-ups not so long ago.

"These companies, regardless of the sector they are in, have one thing in common: many of them owe their genesis to humble beginnings in garages, dormitories and basements where embryonic ideas, which were at the time viewed as crazy, were incubated into reality," said Mteto.
