An investment marketplace is an online platform that connects investors with investment opportunities, ranging from public securities to private equity, venture capital, and pre-IPO shares. In private markets specifically, an investment marketplace typically facilitates deal discovery, due diligence materials, and transaction execution in one place.

Before marketplaces existed in their current form, accessing a private deal usually meant knowing the right people: a fund manager, a broker, or a company insider willing to make an introduction. Marketplaces replace that informal network with a structured, searchable platform.

What is an investment marketplace?

Traditionally, accessing private investment opportunities required direct relationships with fund managers, brokers, or company insiders. Investment marketplaces centralize this process, giving eligible investors a single destination to browse opportunities, review deal terms, and complete transactions, often alongside pricing data and standardized documentation that would otherwise take weeks to assemble deal by deal.

Example: Instead of cold-emailing a startup’s CFO to ask about buying employee shares on the secondary market, an eligible investor can browse a marketplace listing for that company, review available pricing and documentation, and submit an order through a standardized process.

Investment marketplaces for private equity

For private equity and pre-IPO investing specifically, marketplaces typically handle verification of investor eligibility (accreditation), matching buyers with sellers of private company shares, and coordinating the transfer and custody process. This reduces the friction that historically made private secondary transactions slow and relationship-dependent, often taking months to close through informal channels.

How an investment marketplace works

  • Investors verify eligibility, such as accredited investor status, before browsing restricted opportunities
  • The platform surfaces available opportunities, often with supporting data, company information, and disclosures
  • Investors review terms — price, minimum investment, and any restrictions — and submit interest or an order
  • The platform facilitates matching between buyers and sellers, documentation, and settlement, often working with a registered broker-dealer to handle the transaction
Step What happens

Final thoughts

Investment marketplaces don’t eliminate the underlying rules governing who can buy what. What they do is compress a process that used to take weeks of relationship-building into a structured, repeatable workflow, making private markets meaningfully more navigable for eligible investors.
