For Investors
Learn about how SMB investing works on Mainshares
Pre-screened deals. Streamlined experience. Unparalleled support.
Getting started
01
Operator signs a Letter of Intent to acquire a small business
These operators will manage the business full-time after the deal closes, filling the shoes of the previous owner-operator. They undergo vetting by Mainshares, including background checks, credit checks, and an interview.
02
Mainshares reviews opportunity
Once the operator has shared the deal with Mainshares, our team will review the acquisition in its entirety. This includes projections, financing plans, and operator-business fit. We review hundreds of deals each quarter but less than 10% pass our bar.
03
Opportunity posted on Mainshares
Once the deal is ready for investors, the investment opportunity will be posted on Mainshares. Some opportunities are discoverable by anyone in the Mainshares Investor Network, while others may require an invite from the operator.
04
Invest in the opportunity
Once you receive access to a deal, you will be able to review the offering documents, diligence the data room, attend an investor webinar, and build a 1:1 relationship with the operator. If you decide to invest, you can commit directly on Mainshares.
05
Receive distributions & manage your investment
After the deal closes, your investment will show up in your portfolio on Mainshares. You can link your bank account to receive distributions, track quarterly financials, receive investor updates, and vote on any governance items.
06
Sale & disposition
Most SMB investments will provide liquidity through a future sale of the business or the buy-back of your holdings by the operating company within 5-7 years. The terms of any sale or buy-back (i.e., “equity call”) are outlined in the offering documents.
