In the penultimate episode of the season, Katie is joined by Smart Spaces Co-Founder and CEO, Dan Drogman.

Dan starts by reflecting on the last two decades of his career - with Smart Spaces taking up the last 15 years of that time - and how his brother, Tom, gave him the spark to set up their own company after out-performing Dan on his first day of them working together.

Katie asks Dan how he's seen the use of smart offices evolve during his time running Smart Spaces, allowing Dan to explain some of the features he and his team have developed and implemented into their offering, and the benefits they have to landlords and enterprise from an efficiency, sustainability, and conveniece perspective.

The pair discuss the aging housing stock that London is home to, exploring how Smart Spaces investigate the specifics of each building - for example, how long an office takes to reach optimum temperature first thing in the morning - before sharing how much a new client could potentially save by implementing smart technology.

Dan contemplates the potential of a "smart city", and how that would look to the every day person, while sharing his thoughts on technologies that are currently in place that make it more difficult for individuals to get on with their day, using parking apps as an example. He then goes on to share what he believes smart buildings could look like in the future, including the way that humans will interact with the technologies (including, potentially, installing microchips into a person's hand).

As the episode comes to an end, Katie asks Dan what impact he'd like to have on the world, where he shares his ambitions for Smart Spaces, and a hope that it lives on long after he's gone.
