The Future of Digital Coworking

While there are tons of tools out there, Angel Kwiatkowski, founder of Cohere, believes the community is missing an overarching network for coworkers to connect.

"I'm hoping that in the next year, we'll have a great digital tool at our disposal that would allow a member of Cohere in Colorado to easily search out another coworker in say, Pakistan, who might be able to help with a problem or share ideas on a project."
