Tony Fadell: What will Google's $3.2bn guru do next?

Is Tony Fadell destined to eclipse his former Apple workmate Sir Jonathan Ive?

When Google paid $3.2bn (£2.1bn) to buy Tony Fadell's start-up Nest in 2014, it got much more than just an internet-connected thermostat and smoke detector.

It got the man dubbed the "the iPod's father" - the engineer/designer who sold Steve Jobs on his vision of a portable music player, and then worked alongside Jony Ive to build it, update it and then repeat the process with the iPhone.

Now, the two men are set to go head-to-head. First with wearable tech, and then later, perhaps, with competing car designs - more of which later.

Tellingly, Mr Fadell reveals he recently started testing Sir Jonathan's latest product, the Apple Watch, although he was not wearing it at the time of interview.

"I've had mine for about two weeks now," he says.

"I think they did a tremendous job on the hardware components of it.

"They are trying many different things with that platform - some are going to be great, and some are not."

When Mr Fadell agreed to sell Nest to Google, the reason he gave was that joining forces would accelerate his "thoughtful home" master plan - he hates the term "internet of things", which he says does a "disservice" to his products.

But in January, it became clear that Google's chief executive, Larry Page, had wider uses for his hardware expertise, and the troubled Glass computer was added to his duties.

Mr Fadell has taken over control of the Glass project from the Google X skunk works team

"It wasn't handed to me and said, 'Tony clean it up,'" Mr Fadell clarifies, "I offered."

"I remember what it was like when we did the iPod and the iPhone. I think this can be that important, but it's going to take time to get it right."

'Spoil market'

The $1,500 (£965) "explorer edition" of Glass was soon pulled from sale, and Mr Fadell made clear that future test versions would be kept in-house.

That was widely seen as a shift in strategy for Google - a company that took five years to take its Gmail service out of "beta" status, and that still invites users to "play" with preview versions of other products.

Moreover, it caused anger among developers who had sunk time and money into making apps for a product that no longer existed.

But Mr Fadell defends the shift, saying a distinction needed to be drawn between hardware and software.

"If you are only doing services based on electrons, you can iterate quickly, test it, and modify it and get it right," he says.

Google has acknowledged the first version of Glass did not "have the impact" it had hoped for

"But when you are dealing with actual atoms - hardware - and you have to get manufacturing lines and it takes a year or more to develop that product, you better understand what it is and what it's trying to do and specifically what it's not going to do.

"Customers have to spend money to buy those atoms.

"They want something that delivers value or you end up with a real disappointment and you can spoil the market."

Home cam

For now, that leaves Mr Fadell's reputation dependent on his Nest line-up.

Mr Fadell unveiled a slimmer version of his smoke detector, a redesigned and rebranded home camera and new software for his thermostat, in June

It is limited to three products, including the recently launched Nest Cam.

The motion-detecting camera streams live footage and sound from the owner's home to an app and can save memorable moments in the cloud.

If you get over the creepiness factor of effectively spying on your family, it's fair to say the device shares the crisp, stylish look of the Nest's other products, and reviews have been positive.

But the camera is actually an upgrade to an earlier device made by Dropcam - a company Nest acquired.

That means Mr Fadell's division has not created a new product category of its own since joining Google.

Nest Cam can send live video and audio to an app and play back sound sent from the smartphone

Bearing in mind, Mr Page told him to "keep doing what you're doing, and do it as fast as you possibly can", it raises the question: what's taking so long?

"Talk to me about the number of home product companies who have come out with three different product categories in less than five years... are shipping and they are the number ones in their category," says Mr Fadell, slightly bristling.

"I would love to have more, faster.

"But it takes time - it really takes time to make these products to the level of design and near-perfection that we achieve."

Connected fridges

He adds that Nest's biggest goal right now is to expand the range of third-party products its devices talk to - for example its Thermostats can switch LG fridges into energy-saving mode when no-one's in, and its Protect sensors can make Philip's Hue lights flash red if they detect smoke or carbon monoxide.

Larry Page - pictured here with Tony Fadell and Nest's other co-founder, Matt Rogers - spent $3.2bn on Nest, making it Google's second most expensive takeover after Motorola Mobility

But such advances have less impact than a new product.

"Despite his substantial success to date and involvement in key products such as Apple iPod, Mr Fadell has arguably not yet reached the truly iconic status bestowed upon Jonathan Ive," Ben Wood, from the tech consultancy CCS Insight, says.

"Given the huge amount Google invested in the acquisition of Nest to secure his services there must be an expectation that he too can deliver his own portfolio of truly disruptive devices with mass appeal.

"Google still lacks a smash-hit consumer electronics device of its own - it would be sensible to assume it hopes Mr Fadell can deliver that missing element."

Fadell and Ive

Jony Ive and Tony Fadell worked together at Apple on 18 generations of the iPod and the first three generations of the iPhone

The two men worked together on first iPods and iPhones, but are credited with different achievements.

With the iPod, Mr Fadell first convinced Steve Jobs of the wisdom of developing a portable music player and then worked out how to incorporate a hard drive - a fragile component - into a device that could be thrown about, sat on and generally abused.

Jony Ive's breakthrough was his design of its thumb-wheel, which scrolled through songs more rapidly as it was spun more quickly.

With the iPhone, perhaps Mr Fadell's greatest feat was finding a way to shrink the tech necessary to offer a multi-touch user interface on a handheld device.

Jony Ive's skill was best summed up by one writer as making the final product look almost more like "a piece of jewellery than a gadget".

In post-Jobs Apple, Sir Jonathan's influence has grown further - extending to the look of the company's operating system software, the creation of its Watch and even the design of its new headquarters.

By contrast, Mr Fadell has thrived beyond - building and selling a multi-billion dollar company, reinventing mundane household devices as desirable gadgets, and becoming one of Google's key figures.

Driverless cars

This leads to thoughts about whether Mr Fadell could become involved in other Google projects.

A question about working on its growing roster of robots is rebuffed on the grounds that they are still a long way from leaving the lab.

But self-driving cars, he adds, are much closer to launch and a "big curiosity".

"I don't think you've seen anything of what the design of the car could look like when it first materialises," he says.

Google is expected to change the design of its self-driving cars before they exit test status

"How do you make those occupants feel like they are safe and make sure they are safe?

"How does the car exude safety [and be] fashionable as well?

"How does this 'utility' self-driving car also be a reflection of you, right, as well as itself and also be transparent about its safety?

"Those are very interesting questions that still need to be dealt with."

He adds that he has "some thoughts" about the answers and is sharing them with others involved in Google's self-driving car project.

"We are having discussion about them all the time," he says.

Mr Fadell says driverless cars will need to both be fashionable and convey safety at the same time

"I always have ideas - it's whether or not people want to hear them."

So, nothing official yet.

But it would not be a surprise if Google eventually announces Mr Fadell is adding automobile design to his list of duties.

And if, as rumoured, Sir Jonathan and his team are also working on their own electric car concept, that could set up a fascinating clash between the two former colleagues in the future.
