Generate income and grow wealth through SMB investing
Generate cash flow and grow your wealth, while backing the next generation of American entrepreneurs.
A once-in-a-generation moment — the Silver Tsunami
Over the next decade, an estimated $10 trillion dollars of small businesses will be transferred as the current generation of owners retires. These businesses have weathered economic cycles, contribute $11.9 trillion to our GDP, employ over 61 million Americans and are institutions of their communities.

Advantages of SMB investing
Diversify your portfolio
For decades, the 60/40 portfolio of stocks and bonds was the gold standard for diversification. With the rise of alternative investments, the 40/30/30 approach has become the new model. Mainshares helps you hit your 30% of alternatives through private equity exposure in SMBs.
Build passive cashflow
Many SMB acquisitions plan to make quarterly or annually distributions to investors, providing strong cash-on-cash returns to passive owners. By investing across a number of SMBs, investors can build a diversified portfolio generating yield.
Achieve levered returns
Unlike middle market private equity, small businesses trade at relatively lower multiples and typically are bought with 60-90% leverage from Small Business Administration loans. These mechanics can provide strong appreciation at exit.
Invest in your community
Small businesses form the backbone of the U.S., bringing together communities, and providing a majority of job growth. It’s critical that they stay independent, locally owned and contributing to their towns and cities. It’s no surprise that small businesses outrank schools, churches and even the U.S. military in public trust.
