    Y Combinator LogoS2020
    Active • 43 employees • New York, NY, USA
    doola is a “Business-in-a-Box” for creators. We take care of everything creators need to form an LLC, set up their bank account, accept payments, and manage ongoing compliance and tax filings. We realized how difficult it was to set up the full stack of software and accounts you need to get a business off the ground. This is the same problem faced by online businesses, who begin their business as a side hustle, and just want to focus on growing their business, not annoying administrative work. That’s why we built doola: to take care of it all. Today, people on every continent have launched companies with doola. (HQ: New York)
