The first and only regulated copy-trading platform. Modern investors invest based on people and ideas they believe in: memestocks to crypto to politicians to star fund managers like Cathie Woods. Investing in this way should be as simple as a single click.   We've made it possible for the first time ever, where anyone can automatically copy the trades of another user on the app, or be the user who gets copied. The same way you take $10 to invest in Tesla, you take $10 to invest in copying another user's portfolio.   10 years from now, people won't be picking stocks. They'll be picking people on dub to invest. And we'll create the next generation of Warren Buffett's along the way. Backing We've raised $17M from visionaries who support our mission: investors include venture firms like Tusk, Slow, partners at Sequoia and Andreessen Horowitz, and the current and former CEO/Founders of Uber, Airbnb, Robinhood, TIAA, and more.  Team Our team, now at 18, is growing quickly. We come from diverse backgrounds: companies like Affirm, Goldman, Millennium Management, Apple, the US Army and more. We're looking for the most ambitious and hardworking people there are.  Work Style Primarily in office. Some remote for our engineering team.   HQ Financial District, New York City, USA
