BEHIND THE NUMBERS
What this scenario means for an investor.
This scenario applies the stated share prices and conversion assumptions to your chosen amount. The result is a hypothetical value, not a completed transaction.
- Your amount vs. the investment minimum
- Your amount sets the size of the illustration. It does not establish the minimum required to join that funding round.
- Access depends on the offering
- Investor eligibility and allocations depend on the offering’s terms. A recorded funding price does not mean everyone could invest at that price.
- Direct shares and fund units differ
- A direct share and a unit in a fund or investment vehicle can have different rights and costs. This scenario does not establish a specific investment route.
- A price is not a cash exit
- Lockups, transfer restrictions and available buyers can affect a holder’s ability to sell. The displayed value does not assume a sale.
See the data, sources & calculation
The filing table rounds issuance prices to cents; results are approximate. The table date does not establish an investment date. Preferred converts 1:1 into Class B; each Class B is convertible to one Class A share. Secondary employee share sales are excluded. No additional split or holder-specific conversion adjustment is applied. IPO offering-price mark only, not realized proceeds or proof of investment access.
Calculation: amount ÷ reviewed preferred issuance price × assumed conversion factor × IPO offering price.

Published price precision is retained in calculations. A filing snapshot is not necessarily the investment date. These selected companies and stages do not represent typical private-market results; investments can lose their entire value.

WHEN YOU WANT TO GO DEEPER
The story behind Duolingo
What this shows
8 reviewed private share series linked to a historical IPO offer price.
The endpoint matters
$102.00 per share at the historical IPO offering. An offer-price mark is not an executed sale. You can also enter a public price within the reviewed date window.
Read it realistically
Your amount is hypothetical. The evidence does not establish your investment minimum, eligibility or ability to sell.
Compare the supported funding stagesA fixed $10,000 illustration makes the entry points easier to compare.
Selected reviewed stages, not a complete fundraising history. The same hypothetical amount is used in every row. Private investments can lose all their value.

What’s missing matters.
There are no daily private-market prices between these observations. We do not fill the gaps with an invented curve. Investment returns require the specific security, entry terms, dilution and an actual exit or appropriate mark.
