With Grifin you connect your bank account or credit/debit card in order for them to see where you're shopping. Once you shop somewhere, they invest $1 into the company in which you made a purchase from. If the company is not public, they add the $1 to your cash account. Your cash account balance earns interest or you can choose where you would like to invest the sitting cash.

With Grifin you can automate investing into the companies you love. The moment you buy something,  $1 is automatically invested into stock of that company. You connect a checking or savings account or a credit/debit card to put money into your Grifin account to invest. They track your purchases throughout the week, and then each Wednesday, transfer $1 for each 1 purchase from your connected checking account to your investment account. Once your cash arrives in your investment account, they automatically buy your stock for you. If you shop somewhere that you can't invest in (like your local farmer's market) that $1 will be added to your cash fund. Your cash fund earns interest, which is added to your account on a monthly basis.

Grifin does not charge a monthly fee or any commission fees when it comes to commission fees for investing. They believe that it’s your money and you deserve to keep it. While there are no fees to invest, you may have to pay other fees through their brokerage partner, DriveWealth. Grifin likely makes money through:

1. Rebates from market makers and trading venues: Market makers (typically big institutions/funds) buy directly through the brokers to have discounted purchases. For that ability, the market makers pay a rebate to the brokerage to receive their orders . The brokerage sends your orders to the market maker that is most likely to execute at the best price for you and makes a few cents on each trade.
2. Income generated from cash: They borrow the cash sitting in your account and invest it into interest earning accounts and keep the profit.

It is their top priority to earn your respect and keep it. That means they take measures to keep your information and your money well protected.Their brokerage partner, DriveWealth is a member of the Securities Investor Protection Corporation (“SIPC”). SIPC currently protects the securities and cash in your Account up to $500,000 of which $250,000 may be in cash. The SIPC does not protect against the market risks associated with investing.
