Essential Products Inc., the smartphone company from the father of Google’s Android mobile software, is shutting down after less than five years in business and raising $330 million in funding.

The startup said Wednesday it will cease operations and no longer provide software updates or customer support for its $499 titanium-encased smartphone, with its 360-degree camera, 128 gigabytes of storage and minimalistic design. The company had been working on a new device under the name Project Gem, but it wasn’t brought to market.

California-based Essential was attempting to take on technology juggernauts Samsung Electronics Co. and Apple Inc., which have dominated smartphone sales in recent years. Chinese internet company Tencent Holdings Ltd. and Amazon.com Inc.’s Alexa Fund participated in a $300 million funding round for Essential in 2017.

“Despite our best efforts, we’ve now taken Gem as far as we can and regrettably have no clear path to deliver it to customers,” Essential said on its website.

Andy Rubin, the company’s founder, couldn’t immediately be reached for comment. An Essential spokesperson declined additional comment beyond the closure announcement on the company’s website.
