On-demand physical-goods storage startup Clutter Inc. has raised $64 million in a late-stage funding round led by Atomico.

Founded in 2013, the Culver City, California-based company offers a Uber-for-storage type service in that it allows users store extra belongings without actually leaving their house. Users access an app to book a pickup time for the items they want stored and then a driver packs, photographs and catalogs the items requiring storage before taking them to one of Clutter’s storage facilities.

While that might sound like a solution looking for a problem, given that self-storage isn’t exactly rocket science, it’s at this point Clutter actually gets interesting, or as interesting as storing stuff can be. By indexing the stored goods and allocating individual items at their storage facility, users can not only check on whether their item is safely stored via the app but use the app to have individual items returned to them. As the company notes, this means that there is no need to unpack and go through boxes when an individual item is required from storage as is the case with traditional self-storage facilities.

“Storage is one of the few markets undisrupted by technology  — Clutter has had an incredible start, but there’s so much more to do,” Atomico partner Hiro Tamura told Business Insider. “As urbanization increases and rents rise accordingly, more needs to fit into less available space and this has led to a $30 billion market opportunity in the US alone.”

Clutter isn’t the first startup bringing technology and on-demand service to the storage space. A San Francisco-based startup called Trove Technologies Inc. raised $8 million from Greylock Partners in May.

The new Series C round, which included Sequoia Capital, GV and Fifth Wall, brings Clutter’s total funding raised $96.3 million. Previous investors include Amplify.LA, Brick & Mortar Ventures, Four Rivers Group, Grey Wolf, Marc Bell Ventures, Otter Rock Capital, Resolute.vc and Structure Fund. The company said it would use the new funding to expand internationally.
