Wired's oral history of how the London startup scene came to be is a good reminder that, typically, a city needs some great big exits (acquisition or IPO) to really kickstart an ecosystem. In the case of Silicon Valley, you could perhaps trace things back to Fairchild Semiconductor (1950s). But a more recent example of this phenomenon would be the PayPal Mafia, whose members have gone on to found Tesla, LinkedIn, YouTube, and other companies that you may have heard of.

Put simply: success begets success. When a startup does really well and the founders and employees of that company get rich, it is likely that many will go on to found/fund other successful companies in that same city. In the case of London, that catalytic startup was arguably Skype (at least according to Wired). Microsoft acquired the company in 2011 for $8.5 billion, giving birth to the Skype Mafia. Of course, that wasn't the only ingredient, but it sure helped (excerpt from Wired):

Since 2008, according to data compiled by Dealroom.co, the UK has created 60 unicorns (tech companies valued at $1bn or more) – 35 per cent of the 169 created across Europe and Israel. In the past three years, the UK has created more unicorns (25) than France, Germany, the Netherlands and Sweden combined (19). And London has produced 23 unicorns with a combined value of $132bn, compared with Berlin’s eight, worth $32bn.

The world has changed since Skype was founded. It's now cool to be doing a startup. But given that every city seems to be trying to establish a thriving startup scene, I think it's valuable to point out just how important a single big exit can be, not just for the people within the company, but for the broader city. Easier said than done, right?

London is currently running a 12-month pilot on its first ever 3D zebra crossing. The objective is to improve pedestrian safety by making the crossing more visible to drivers. A 3D zebra crossing stands out by appearing to float above the road.

Here's a photo (image credit to Gusti Productions):

While this is the first of its kind in the UK, similar crossings have already been installed in Iceland, India, Taiwan, and other countries. According to the trials in India, they do appear to have a meaningful impact on vehicular speeds. They also feel like public art.

If this first one proves to be successful, the plan is to roll out these 3D crossings across the entire borough of Westminster. Assuming they do actually work, I'm surprised there hasn't been more noise around them here in Toronto.

A London-based software company is also working to completely rethink the zebra crossing for today's smartphone world. Their system imagines LEDs embedded into the street so that a crosswalk can be triggered basically anywhere.

Perhaps this is something that might work with the street paving that Sidewalk Toronto is piloting.

Some of you may want to debate the “center of the world” title (New York may be more deserving), but Laura Parker of National Geographic recently published a great essay describing the tremendous growth that London has seen over the last 30 years thanks to in part the deregulation of the financial services industry. Here is an excerpt:

As the manufacturing industry splintered, the docks of what was once the world’s largest port fell victim to shipping modernization and closed. The death in 1965 of Winston Churchill, the great prime minister, marked “the last time that London would be the capital of the world,” the Observer noted. Population continued a downward slide, bottoming out at 6.7 million in 1988. By then London’s fortunes had changed with deregulation of the financial services industry, known as the Big Bang, along with the shift to electronic trading, which enabled London to rival Tokyo and New York. A new financial district rose on the ruins of the West India Docks on the Isle of Dogs, a marshy nub that juts into the Thames. Canary Wharf, as the district is called, became London’s first modern large-scale regeneration project.

According to National Geographic, London’s population grew by about 1.2 million between 2006 and 2016. That’s a pretty incredible number and is why the city estimates that they need about 66,000 new housing units a year just to keep up the growth. Like many supply constrained big cities, they’re not meeting that target.
