It’s been a hectic day at LeWeb in Paris – the 10th edition of the conference. Here’s five thing’s I’ve taken away from the day:

It’s all about the network

OK, that sounds all very obvious, but Fred Wilson’s talk was powerful and really cut through some of the nonsense talked about social business and enterprise 2.0. It’s not something you can just paste on top of existing businesses – it’s a fundamental reinvention of how businesses operate, and an abandonment of the old hierarchical model of work. He talk was full of useful pointers on the future direction of the internet.

Physical goods enhance digital ones

An unusually subdued Phil Libin of Evernote gave us some startling statistics about the launch of Evernote Market, which sells physical goods which have some relevance to the online note service. In just two months it’s accounting for 30% of their revenue, drawing in new customers – and boosting take-up of its other paid products. Digital and physical are becoming deeply intertwined.

You can measure aptitude for entrepreneurship

Tony Tjan, CEO & Managing Partner, Cue Ball compared entrepreneurship to way finding on the seas – tracking to a destination without a map or compass. He’s formalised a piece of research into how entrepreneurs operate into what he calls the entrepreneurial aptitude test. It tries to determine your style of decision-making, and thus what sort of a founder you’ll make.

You’re not mobile first until it’s totally embedded in the company

Twitter’s Michael Sippey revealed that they now have iOS and Android developers in every major product team in the company. They’re not separate units, but utterly integrated parts of the way the company operates. There’s an experimentation framework within the apps. You might be in a test bucket where you’re seeing an experiment that only a tiny proportion of their users are seeing…

Collaborate to win

Jeremiah Owyang gave a very different talk to usual, and it became clear why: he’s launching a new company. It’s focus in on helping companies understand how to truly collaborate with the crowd – their customers and others – in a way that benefits them both. That, he argued, is the only way to make big businesses that will be resilient enough to survive.
