What investors are on DuckDuckGo’s cap table and how much equity do they hold?

1. Who the known investors are (what the public records say)

Public private‑market databases and reporting collectively name a recurring set of institutional backers: Union Square Ventures and OMERS appear in multiple investor lists ^{[2] [1]}, GP Bullhound and Impact America Fund were reported as lead investors in a 2021 round ^[3], PitchBook lists Avenir Growth Capital, Bracket Capital, Fifth Down Capital, K5 Global and Late Stage Management among others ^[8], and sources such as Crunchbase and other platforms have flagged Tiger Global and other late secondary participants ^{[4] [9]}. TechCrunch’s reporting on DuckDuckGo’s disclosure of a substantive “mainly secondary” $100M+ transaction also names a mixture of existing and new investors without publishing a definitive roster or percentages ^[5].

2. How much DuckDuckGo has raised — and why that matters for stake sizes

Different vendor tallies vary: PitchBook and some platforms report DuckDuckGo has raised figures in the tens of millions or low hundreds of millions across rounds (PitchBook lists $72M in one snippet; other vendors show totals ranging from ~$71M to $172M and $113M depending on dataset) and Forge/Dealroom/Tracxn show divergent totals and round counts, illustrating data inconsistency in private markets ^{[8] [2] [1] [3]}. Those aggregate financing totals set the pool of capital that investors bought into, but without valuation data tied to each round, one cannot convert dollars invested into percentage ownership with confidence ^{[2] [9]}.

3. What is known about the 2020/2021 $100M transaction and why it obscures cap‑table clarity

DuckDuckGo disclosed receiving “$100M+” in a transaction that TechCrunch described as “mainly secondary,” meaning much of the cash bought shares from early employees and investors rather than funding new company issuance; secondary deals redistribute existing equity and therefore can involve new buyers without changing founder/common ownership in the same way a primary round would ^{[5] [9]}. Reporting confirms the transaction included a mix of existing and new investors but does not itemize who acquired which number of shares or how that shifted percentages on the cap table ^{[5] [9]}.

4. Why precise equity percentages are not publicly available

DuckDuckGo is privately held and does not publish a public cap table or routinely file ownership disclosures like a public company; secondary marketplaces and private databases can show participant names, transaction sizes, or aggregate funds raised, but none of the sources supply verifiable, granular percentage stakes for each investor ^{[7] [6] [8]}. Some third‑party writeups attempt estimates — for example one site offers percentage guesses for select investors — but that analysis is explicitly speculative and not corroborated by primary filings or company confirmation ^[10].

5. Reconciling the evidence and the practical answer

The verifiable answer: institutional and angel investors identified across sources include Union Square Ventures, OMERS Ventures, GP Bullhound, Impact America Fund, Avenir Growth Capital, Bracket Capital, Fifth Down Capital, K5 Global, Late Stage Management, Tiger Global and assorted secondary buyers and individual backers, and DuckDuckGo disclosed a $100M+ secondary that reshuffled some holdings ^{[1] [2] [3] [8] [5] [4]}. The practical limitation: none of the cited sources publish a definitive cap table with exact percentage ownerships, so it is not possible from the available reporting to state how much equity each investor holds ^{[7] [6] [10]}.
