Business Models Of Micro-Investing Platform

Micro-investing platforms have revolutionized how individuals can participate in the financial market. By prioritizing accessibility and convenience, these platforms enable users to easily manage their investments directly from their smartphones. Let’s explore some of the prevalent models in the micro-investing space:

  • Round-up Model: The round-up model links users’ investment accounts to their debit or credit cards. Each transaction is rounded up to the nearest dollar, and the spare change is automatically invested into a diversified portfolio of stocks and bonds.
  • Subscription Model: This model charges a monthly fee for access to investment services. Subscribers typically gain access to a robo-advisor that offers algorithmic investment advice and manages their portfolio on their behalf.
  • Fractional Share Model: In the fractional share model, users can invest in fractional shares of stocks and exchange-traded funds (ETFs) with minimal amounts, sometimes as low as $1. Users can either choose from a predefined list of investment options or create their own custom portfolios.
  • Cashback Model: Under the cashback model, users earn cashback rewards on their purchases. These rewards can then be automatically invested into a portfolio of stocks and bonds, seamlessly integrating spending with investing.
  • Social Trading Model: This model allows users to follow and replicate the investment strategies of successful investors on the platform. By observing and copying these strategies, users can benefit from the expertise of experienced investors.
  • Partnerships: Micro-investing platforms often form partnerships with financial institutions such as banks and brokerage firms. These partnerships provide access to a wider range of investment products and services while generating additional revenue streams for the platforms.

Best Micro-Investing Platforms on Smartphones

Don’t abuse the number of apps on your iPhone. Otherwise, don’t be surprised when it starts to work slowly. You can also quickly clear the memory if you download a cleaner app from the App Store, which removes duplicate photos, allows you to compress videos and removes garbage from the memory. Bonus – the ability to create a protective partition in the smartphone’s memory.


First launched in 2013, Robinhood is a leading micro-investing app known for commission-free trading. It was the first to offer this feature, which attracted a large user base. Besides stocks, Robinhood lets you trade options, index funds, and cryptocurrencies without any commission. For more investment options, you can upgrade to Robinhood Gold for $5 per month. However, note that Robinhood does not support mutual fund trading.


Acorns is aptly named; just as a small acorn grows into a mighty oak, small investments can grow into substantial wealth. This app not only helps you invest but also educates you on money basics like taxes, retirement, and crypto. Acorns offers two plans—Personal ($3/month) and Family ($5/month)—and isn’t free. After linking your debit card, it rounds up purchases and invests the spare change once you have over $5. You can either trust the app to make investment decisions or set your preferences for guidance.

Micro-investing platforms are an opportunity for everyone to join the world of investing. Money should work and that’s true, but the barrier to entry for most types of investments is too high. Even if your budget allows for one large investment, wouldn’t it be better to split the funds into 10 segments to diversify the risks? That’s the beauty of micro-investing.
