Last week, news came out that Twitter co-founder Biz Stone is working on a new startup called Jelly. Today, Stone opened up about it a bit.

In a post at JellyHQ.com, Stone writes:

People are basically good—when provided a tool that helps them do good in the world, they prove it.

Jelly is a new company and product named after the jellyfish. We are inspired by this particular animal because neurologically, its brain is more “we” than “me.” Also, for the past 700 million years, this decentralized structure has been wildly successful.

News of Jelly emerged unexpectedly early so I’ll wait a bit to share more about the team. In the meantime, I’ll say this. Jelly will be for everybody, it will be developed first and foremost for mobile devices, and it will be free. But, it won’t be ready for a while.

Personally, Jelly will command my full attention aside from some advisory roles elsewhere. The company is self-funded for now. Our offices are based in San Francisco. We are hiring, but Jelly is in no rush to be a big company any time soon.

According to Kara Swisher, a source referred to Jelly as a “native mobile” effort, and Stone has already hired four or five employees.

Presumably this is independent from Obvious, which Stone also co-founded, and is working on things like Medium, Lift and Branch.
