How much does Mainvest cost?
Mainvest features
Five-point vetting process
- Anti-fraud vetting. Mainvest “must have a reasonable belief that each business that launches on the platform does not raise a risk of fraud or otherwise raise an investor protection concern.” That said, this doesn’t mean the platform's investment opportunities come without risk — all investments require some risk.
- Responsibility check. Before a business can become a Mainvest business, the company does a Responsibility Check to ensure that the business owners are prepared, can communicate effectively, and have a good head on their shoulders (e.g., no concerning social media activity or missing financials).
- Bad actor check. Once a business clears the Responsibility Check, the next step is to go through the Bad Actor Check (BAC) — a limited background check of the business, its managers and officers, and anyone else who owns 20% or more of the business.
- Yellow flag BACs. Mainvest also pulls Yellow Flag BACs. These could include traffic tickets, lawsuits, etc. If something raises a concern, it’ll be reviewed during this process.
- Continuous review. Those who manage to pass the previously-mentioned steps will be under continuous review. This means that even businesses accepted into the program are subject to retraction if there’s a chance of fraud or risk.

Pros and cons
- Low minimum. Mainvest makes it easy to start investing. All you need is $100 to invest in one or more local businesses across the U.S.
- Several investment options. Mainvest offers a variety of investment options, from small bakeries to cannabis to livestock.
- Solid vetting process. Mainvest helps reduce your investment risk by thoroughly vetting each business listed on the platform.
- Better Business Bureau (BBB) accredited. Mainvest is accredited by the BBB and has maintained an A rating since 2019.
- Track record repayment rate. Mainvest reports a track record repayment rate of 96%.
- High target returns. According to the Mainvest site, investors see 10–25% returns.
- Risk. There are risks associated with any investment you make. If a Mainvest business fails to pay you on time, one of two will happen: balloon payments: This is where a business repays an investor a lump sum and defaults: If the business defaults, interest will accrue on the amount owed. An investor can seek legal action to force the business to pay what’s owed or bankruptcy. Note: Mainvest does not/will not help you with this.
- Investments are illiquid. When you invest on Mainvest, you’re stuck with that investment until the maturity date. This is because Mainvest works by allowing investors to finance business debt (there’s no secondary marketplace and no equity to sell), and no equity means no liquidity.
