Canonical is aiming to raise $32m (£21.5m) in crowdfunding to develop its next smartphone, the Ubuntu Edge.
The campaign aims to raise the cash in just a month on Indiegogo, for a limited production run of 40,000 devices.
The British open-source company claims that the smartphone will be the world's first truly converged personal computing device.
Mark Shuttleworth, founder of Ubuntu, told Techworld: "We got excited about the idea that we could engage with a community with crowd funding. It's a really powerful new way to connect innovators to early adopters and to spread the risk of innovation across people who are really interested."
He added that Canonical is in talks with several big name handset makers ahead of the full retail launch next year.
The Ubuntu Edge will be equipped with at least 4GB of RAM and 128GB of storage but the processor was not revealed. It will also come with dual-LTE, and a silicon anode battery.
Meanwhile, the phone itself will boast a 4.5-inch, 1,280 x 720 sapphire crystal screen, an 8MP rear/2MP front-facing camera and stereo speakers.
Pledgers committing $600 (£394) on day one, or $830 (£592) thereafter, will receive one of the devices in May 2014.
Last month Canonical formed a Carrier Advisory Group to discuss how to develop the platform and things like ways to differentiate it for operators and which HTML 5 standards it should support. The group is made up of EE, Deutesche Telekom, Korea Telecom, telecom Italia, LG UPlus, Portugal Telecom, SK Telecom and Telefnica.
If the Edge doesn't reach its target figure then Canonical won't produce it.
