There's a bunch of brokerages offering fractional shares, such as Betterment, Motif, M1, Stash, Stockpile, and others. Schwab has also announced they'll be adding it.

There's also DRIP (Divident ReInvestment Plan) plans, a feature brokerages offer to allow fractional reinvestment of dividends.

Not sure how it's actually implemented as a financial product.

Most of them are implemented through Apex clearing.
