“The subpoena sent to Circle Internet Financial, a bitcoin services startup that received $9 million in venture capital funding in October, asked for information ‘pertaining to a criminal investigation that the (DoJ) is undertaking’ into ‘a company,’ said Circle CEO Jeremy Allaire. Allaire declined to identify the company named in the subpoena but said he suspected Circle had received the request because of its public response to the Mt. Gox shutdown. Allaire, who founded Circle last year in Boston, said his company had never had commercial dealings with Mt. Gox and that ‘serious’ businesses in the Bitcoin community had stayed away from the exchange for nearly a year.”
