What is the Public app?
Public is a free social trading app and an investing social network. Formerly known as Matador, the app launched in 2019 to make investing easily accessible to everyone. With Public, you can:
- Invest in fractional shares (“slices”) of stocks and ETFs
- Follow your friends or popular influencers and share your ideas
- Invest in thematic stocks and funds
- Invest in crypto and hold it in the same app as your stock portfolio
Historically, many groups of investors missed out on the market’s returns, and Public’s goal is to correct that by making investing easy. The app has a user-friendly interface and has already surpassed 1 million users despite being launched only two years ago. Public is also inclusive: according to CEO Jannick Malling, 40% of investors are women, and 45% are minorities.
Public’s backers include Will Smith, Professor Scott Galloway, Girlboss founder Sophia Amoruso, and skateboarding legend Tony Hawk. You can follow various celebrities on the app and see how they invest.
All users on the platform are verified, and the overall vibe is supportive. By verifying all the users, Public avoids the less savory aspects and the anonymity of some popular Reddit boards.
Public is committed to helping you invest rather than day trade or speculate in the short term. 90% of users say that they are mostly long-term investors. As a result, Public doesn’t offer options trading. Tellingly, when you look up a stock, the button next to it says “Invest” and not “Buy.”

What is Stash Invest?
Stash is a personal finance app that makes investing easy for beginners. Wall Street veterans Brandon Krieg and Ed Robinson started Stash in 2015 with the mission of making investing inclusive and accessible to ordinary Americans. As of 2020, Stash grew to over five million customers and $2.5 billion in assets under management.
In addition to making investing easy, Stash offers a bank account with a Stock Back Card (which gives you cash back in stocks). Stash Invest also has a robo-advisor, Smart Portfolios.

Public vs. Stash: Account types
Public lets you invest through your taxable investment account only.
Stash supports the following account types, though their robo-advisor only works with individual investment accounts:
- Taxable personal investment accounts
- Retirement accounts for traditional and Roth IRAs (Stash Growth and Stash+ members only)
- Custodial accounts for kids (Stash+ members only)
💰 The winner: Stash, which supports more account types. Public doesn’t offer retirement or custodial accounts.
Public vs. Stash: Banking
Public doesn’t have any banking options.
Stash offers checking accounts with a debit card through a partnership with Green Dot Bank. If you set up a direct deposit, you have the option to get your paycheck two days early, too. And you can make instant transfers between your checking and investing accounts.
Stock Back Rewards. Stash accounts come with a Stock Back rewards card. When you spend money at places like Amazon (AMZN) that have stocks listed on the platform, you get 0.125% back in stock in the companies where you make purchases. Stash+ members get 0.25% back. If the place where you spend money doesn’t have a publicly listed stock, you can choose what stock or ETF to get.
💰 The winner: Stash, since Public has no banking option. However, Stash checking accounts don’t pay interest, and the cash back rate is low. If you are looking for a sustainable banking option with a high APY, check out Aspiration.
Public vs. Stash: Minimum investment
Public has no minimum balance to open an account, though you need $5 to make your first investment. That is easy because they give you free stock when you sign up.
Stash lets you start investing with $5.
💰 The winner: Tie. In practice, both apps have no real minimum.
Public vs. Stash: Commissions and fees
Public is free. The app makes money from optional tipping, lending your shares, interest on the cash in your account, and markups on crypto trades.
Stash charges $1-$9/month for membership. There are three membership plans:
- Stash Beginner ($1/month) includes a personal investment account, a Stock Back Card, and $1,000 worth of life insurance coverage through Avibra
- Stash Growth ($3/month) adds a Roth or Traditional IRA to the Beginner features
- Stash+ ($9/month) comes with all the Beginner and Growth features, plus a Stock Back Card that earns double stock, investment accounts for kids, a monthly market insights report, and $10,000 of life insurance coverage through Avibra
$1-$9/month may be quite expensive as a percentage if you have very little invested. Robo-advisors like Betterment, Marcus Invest, and Ally Invest charge 0.25%-0.35% of assets for managing your money.
If you only put $1,000 in your Stash account and sign up for Stash Growth, you are paying 3.6% of your assets annually. And, if you are not using Smart Portfolios, Stash doesn’t actually manage your investments as a robo-advisor would. It’s more like a brokerage. However, if you invest $10,000, you are paying 0.36%, which is more reasonable, and you get perks like the Stock Back card and life insurance.
💰 The winner: Public, which is free. Stash can end up being very expensive for smaller account balances.
Public vs. Stash: Stock selection
Public lets you choose from 9,000+ stocks and funds.
Stash offers around 4,000 stocks and ETFs to choose from.
💰 The winner: Public.
Public vs. Stash: Crypto
Stash doesn’t offer crypto, but Public supports 25 cryptos, including:
- Bitcoin (BTC)
- Ether (ETH)
- Cardano (ADA)
- Dogecoin (DOGE)
- Litecoin (LTC)
- Bitcoin Cash (BCH)
- Shiba Inu ($SHIB)
- Stellar (XLM)
- Ethereum Classic (ETC)
- Dash (DASH)
- Zcash (ZEC)
💰 The winner: Public.
Public vs. Stash: Sustainable investing options
Both Stash and Public let you find sustainable investing options, including stocks that score better on environmental, social, and governance metrics like carbon emissions as well as clean energy investments.
Public thematic investing
Public helps you find ESG stocks and funds easily by grouping them into themes. As of December 2021, they featured the following themes:
- Women in Charge: public companies led by female CEOs
- Diverse Leadership: companies that are setting the bar when it comes to diversity and inclusion
- Plant-Based Movement: companies innovating & investing in plant-based food for a better-tasting and greener future
- Reuse and Reduce: companies converting waste materials into new materials and objects
- Combat Carbon: companies actively working towards reducing their carbon footprint
- Green Power: these energy companies produce power through sustainable and renewable means
- Immigrant Founders: U.S.-based companies that were founded by immigrants
- Water Works: companies responsible for supplying and purifying drinking water
For example, if you select the “Green Power” theme, the app will suggest a list of stocks like Tesla (TSLA) and NextEra Energy (NEE) and ETFs, such as the Guggenheim Solar ETF (TAN). This makes ESG stocks and funds easy to find.
Stash Missions & Causes
Stash groups ETFs into themes, which makes ETF investing accessible for beginners. We were particularly interested in the Missions and Causes selection, which offers six thematic funds. The funds cover water, low-carbon, women leadership, cannabis, clean energy, and high environmental, social, and governance (ESG) score funds. Here is the list:
- Women Who Lead: SPDR SSGA Gender Diversity Index ETF (SHE)
- Water the World: Invesco Water Resources ETF (PHO)
- Combat Carbon: iShares MSCI ACWI Low Carbon Target ETF (CRBN)
- Clean & Green: iShares Global Clean Energy ETF (ICLN)
- Corporate Cannabis: ETFMG Alternative Harvest ETF (MJ)
- Do the Right Thing: iShares MSCI USA ESG Select ETF (SUSA)
💰 The winner: Public. Both apps have a good selection of sustainable stocks and funds and make finding these options easy, but Public has more options and goes beyond funds by showing you stocks, too.
Public vs. Stash: Fractional shares
Both apps let you buy fractions of shares.
Fractional shares allow you to buy a piece of a share if buying the entire thing is more than you would like to spend. For example, one share of Tesla (TSLA) stock costs $1,000, but if you only want to spend $100, you can buy 1/10 of that share. Buying fractions of shares limits how much cash is sitting in your account unspent.
💰 The winner: Tie.
Public vs. Stash: Roundups
Stash lets you round up your purchases to the nearest dollar and invest the roundups once they hit $5.
💰 The winner: Stash. Public doesn’t offer this option.
Public vs. Stash: Margin lending
Neither app lets you borrow against the value of your investments. But if you are looking for a margin loan, you can check out M1 Finance.
💰 The winner: None.
Public vs. Stash: Automatic rebalancing
Public doesn’t offer any rebalancing, and neither does Stash if you build your own portfolio. Stash Smart Portfolios does offer quarterly rebalancing.
Automatic rebalancing is when a robo-advisor buys or sells investments to get to your optimal asset allocation, like 80% stocks and 20% bonds. Sometimes when one asset class, like stocks, does much better than another one, like bonds, your portfolio may “drift” and become riskier (or less risky) than it should be. Automatic rebalancing solves that.
💰 The winner: Tie. Neither app offers rebalancing unless you choose Stash Smart Portfolios, but that doesn’t have any sustainable options.
💰 The Overall Winner
Best for no fees and for active and crypto investors: Public. Public is free. And it is great for investors who want to follow other investors’ trading activity. It is great for:
- No commission or membership fee
- Social investing
- 9,000+ funds and stocks to invest in
Best for beginners struggling to save: Stash. Stash lets you round up your change and invest it. You can also get a bank account or invest through your retirement account. Stash is best for:
- Round up and invest your change
- Retirement accounts
- Bank account with a stock rewards debit card
