Crowdfunding platforms for investing have changed who can put money into private companies. Once reserved for wealthy insiders, private investing is now open to anyone who wants to build a portfolio outside the stock market.

There are many platforms that offer these opportunities, but not all focus on the same types of businesses or structures. Some specialize in high-growth startups. Others make it easy to back local businesses or even buy into real estate. Here’s how to understand the landscape so you can decide what matches your interests and goals.

Platforms for Startup Equity

These platforms let you invest in private companies by buying ownership stakes. If the company grows or is eventually acquired or goes public, your shares could increase in value.

Republic (Click here)
A large platform that features startups in tech, consumer products, climate, health, and more. Republic also has separate sections for crypto and real estate. Minimums often start at $100, making it accessible for new investors.

Wefunder (Click here)
One of the largest equity crowdfunding platforms in the U.S. You’ll find everything from local restaurants to high-growth tech. Minimum investments start around $100, and each campaign includes detailed risk disclosures and business plans.

StartEngine (Click here)
A broad marketplace with many early-stage deals. Known for high deal volume. StartEngine is also developing a secondary market so investors might eventually sell shares before a full company exit.

MicroVentures (Click here)
Combines startup investments with some venture fund opportunities. Also lists pre-IPO shares from time to time. It bridges traditional angel investing and modern crowdfunding.

Platforms for Pre-IPO and Secondary Shares

These platforms let you buy shares from early employees or investors in companies that are later-stage. This can give you access to businesses preparing to go public.

EquityZen (Click here)
Specializes in secondary sales of late-stage private companies. You buy from insiders looking for liquidity. It is often used by investors who want to get into well-known companies before they list on the stock market.

What to Keep in Mind

These platforms make private investing far more accessible, but risk is still high. Many early-stage companies will not succeed, and local businesses can struggle with market shifts. Investments are usually illiquid, meaning your money could be tied up for years. Always use funds you can afford to keep locked up for the long term.

The Bottom Line

Crowdfunding platforms for investing have opened up private markets to more people than ever. Whether you want to back a promising tech startup, fund a local business, or diversify into real estate, there is likely a platform that fits your interests. Knowing how each one differs helps you invest with more confidence and build a portfolio that matches your goals.
