The businesses represent some of London’s most exciting smart cities innovators, offering solutions across big data, clean tech and transport.
They include London taxi app Gett Taxi, which received a US$300m investment from Volkswagen earlier this year, parking app JustPark, and NFC Ring, a wearable device for making contactless payments.
The companies will showcase their projects at the world’s largest smart cities conference, the Smart City Expo World Congress.
Agrawal said: “London is already a world leader in tech, with some of the best talent in areas such as big data and sustainability.
“The companies on this trade mission are part of the capital’s thriving sector, which is at the forefront of developing cutting edge technologies which will change the way cities function.
“The mayor and I are clear that digital technology and data have a vital role to play in the future of our public services, in energy, water, safety, transport and city infrastructure.
“And our progress in these areas, supported by an exceptional talent pool, will create opportunities for all Londoners and realise our ambition to becoming a truly smart city.
“There is a growing opportunity to work with cities across the world to develop innovative solutions to our challenges and London will always be open to sharing ideas and talent with the entire globe.”
The three-day trade mission is being led by the mayor’s International Business Programme in partnership with Imperial College London, Camden Council and Digital Greenwich. The travelling companies will be given the opportunity showcase their innovations, meet with leading investors and explore export opportunities.
The trade mission to Barcelona is the latest overseas visit organised by the International Business programme, which helps the capital’s high-growth firms to break into new international markets or grow their existing operations overseas.
Since the launch of the programme in February this year, more than 150 of London’s fastest growing companies have joined the programme which has already led trade visits to countries including the United States, Israel, Germany and China.
