Based on that article specifically.
>> The only early investments were $2 million from the U.S. Central Intelligence Agency's venture capital arm In-Q-Tel, and $30 million from Thiel himself and his venture capital firm, Founders Fund.[6][7][13][14][15]
Sounds like the CIAs investment arm funded Palantir and didn’t found it, the funding amount also seems pretty inconsequential given the overall funding.
