Pre-IPO due diligence checklist

By Unicorn Private Research. Published and last updated 2026-09-20.

Key takeaways

Buying shares of a private company involves checks that do not exist on a public exchange. The following ten questions are a practical starting point for qualified investors and their advisers.

The ten questions

  1. Which share class is being sold, and what rights does it carry compared with preferred shares?
  2. Does the seller hold the shares directly, and is the seller authorized to transfer them?
  3. What do the company's bylaws and shareholder agreements say about transfers, and is board approval required?
  4. Does a right of first refusal or co-sale right apply, and has it been waived in writing?
  5. How does the price compare with the most recent priced funding round and with recent secondary transactions?
  6. What liquidation preferences sit above the class being bought, and how would they affect proceeds in a sale?
  7. Is the exposure direct or held through an SPV or fund, and what fees and carried interest apply at each layer?
  8. What information will the buyer receive after closing, such as financial statements and cap table updates?
  9. What are the tax and regulatory consequences in the investor's jurisdiction, including investor qualification rules?
  10. What is the expected exit path, an IPO or a strategic sale, and how would lock-up periods affect liquidity?

Why specialized execution matters

Identifying genuine sellers, negotiating terms and structuring the agreement each require specific expertise. Errors at any step can invalidate a transfer or leave the buyer with fewer rights than expected.
