City Lab – in its third year following on from past events in Los Angeles and New York – took place last month in London’s city centre. Attending the 3-day event were city mayors, urbanists, architects and innovators from across the globe.

Taking a step back from the second day’s headline speakers including current London mayor Boris Johnson and former New York City mayor, Mike Bloomberg, Jo Barratt spoke with Elana Berkowitz, a strategic advisor to startups and philanthropic investors. Elana speaks about what City Lab offers in terms of behind the scenes technology and diversity among the litany of important speakers, buzzwords and data, smart cities and innovation soft talk.
