Daniel Daoura was enjoying an afternoon with his daughter at the Puyallup Fair last month when the young girl bolted into the crowds. Having lost eyesight of her, he panicked momentarily before reaching for his phone and opening up his Pebblebee app. Daoura, one of the company’s co-founders, had happened to put one of the small Bluetooth tracking devices in his daughter’s pocket and quickly found her, mischievously standing near the cotton candy booth.

About the size of half dollar coin and weighing next to nothing, Pebblebee’s flagship device called the Honey is a short-range tracking device that can be attached to nearly anything and be located in the 150 foot range using their Android and iPhone app, although Dauora said it’s not intended for use with children.

The idea for the device was started with children in mind though after co-founder Nick Pearson-Franks’ toddler son began hiding stuff around the house. “I kept thinking to myself, ‘How is this such a hard problem to solve?’” the former Boeing employee said.

Since it’s launch, Dauora and Pearson-Franks have heard stories ranging from people using their Honey trackers to find missing purses to missing turtles. The accompanying app also uses crowd GPS from all users to search for items marked lost by other users.

What started as a small project has now grown to a 20 employee business. Their new 4,000-square-foot Bellevue location is double the size of their previous Kirkland offices, and is their fourth location.

An IndieGoGo campaign for the product easily surpassed the $20,000 fundraising goal and has sold more than 100,000 units in less than a year. “It was just overwhelming, we never would have predicted that success. We just thought it would be a side project,” said Pearson-Franks.

For the last two years, Pebblebee has competed to create the best Bluetooth device for missing items in the rapidly growing market. But the start-up, which moved to Bellevue in September, is on the brink of expanding their reach and launching two new products that will build on the Honey.

Bluetooth GPS technology is a growing industry, and Pebblebee has its competitors. Despite the similar price points, the Pebblebee team say their products have a better life expectancy, battery life, more features and more.

Their new Bellevue office houses a laboratory that the team is using to test their new products. As opposed to many other companies, everything in the Pebblebee products is made in the United States and engineered in-house, according to Pearson-Franks.

Pebblebee also has a wider range of products than their competitors, he added.

Launching in late November to early December, Pebblebee’s second product – the Stone – will include a GPS tracker but also includes a button that can be programmed to send quick text messages, control music, take photos and more. “The stone emerged because it became clear that there’s a lot of stuff you can do with a button function,’ said Pearson-Franks.

The team is also working on a third product, the Dragon, that will be launched at the same time or shortly after the Stone and match 3-D motions made while holding the device to tasks.

The array of Pebblebee products cost between $24.99 and $60 apiece, and are available online and in Target stores. More information can be found at https://pebblebee.com/.
