Staax lets you pay and get paid in fractional shares of stock for everyday transactions. We make investing in stocks social, and allow you to embed investing into your lifestyle. On Staax you can send your friends as little as $1 of stock for dinner last night, phone bill, or coffee! Start building your portfolio with friends today. INTRODUCING PAYMENTS IN STOCKS: Staax lets you build your portfolio just by getting paid back by your friends. Instead of getting paid back in cash for reimbursements, you can choose to get paid in any of your top five favorite stocks. You can change your mind and swap out for cash as well, if you prefer to receive a different stock or later invest it at a different date. We encourage everyone to focus on the long-term benefits of investing, and contributing to their portfolio in a diverse and frequent way. NO FEES: We take $0 commission on stock / ETF trading and payments. There will be no fees regardless of the dollar ($) amount transacted or invested. FRACTIONAL SHARES: Invest, send and receive as little as $1. Invest in the companies you believe in with fractional shares, without any pressure to buy whole shares of stock. BECOME SOCIAL: Receive access to a rolling feed of real-time transactions that are happening within your community, where you can engage in conversation by “liking” and “commenting”. Check out what stocks people are sending, receiving, and investing in. Follow your friends, and gain insight on their favorite stocks. Directly invest in your friends every time you pay them back, and contribute to their long-term portfolio. Learn to invest in a social environment! EXPLORE: Search for friends, stocks, and ETFs on the explore page. Check out what’s trending, and keep up to date on current events by getting access to in-app news article links. SAFE AND SECURE: At Staax, we’ve got your back, and we hold privacy and security to the highest standards. We use bank-level security, SSL and 256-bit encryption to ensure your information is fully protected. We use Plaid to link your bank accounts, which is a safe and secure way to transfer your funds into Staax.
