A Waterloo entrepreneur who has set up a business teaching first aid skills to parents has won £1000 and an iPad mini at the Brand Amplifier awards on the South Bank.
17 female entrepreneurs pitched their business ideas to an all-women judging panel.
Brand Amplifier selects a shortlist of candidates to take part in an intensive four-week workshop programme run by inspirational female entrepreneurs.
Candidates benefit from these women's insights on building powerful brands and having the courage to take risks and learn from mistakes along the way.
"Brand Amplifier has grown from strength to strength over its four-year run, and the 2013 edition proved that innovation, passion and original concepts are alive and well among the women of Lambeth," said founder Jeannette Prichard.
Sarah Kohn set up Early Bird First Aid in 2011. She said: "We all live busy lives but spending three hours doing a first aid course could save the life of a loved one. Surely that is time well spent?
"If first aid skills were introduced as a compulsory part of the school curriculum in the UK, many more people would have the confidence to offer help in an emergency situation."
This week's award ceremony was attended by 5 News presenter Emma Crosby and the Mayor of Lambeth Cllr Clive Bennett. The judging panel included broadcaster Georgie Bingham.
