(Reuters) - U.S-based cancer testing startup Grail Inc, which has received funding from Amazon.com Inc (NASDAQ:AMZN) founder Jeff Bezos, on Wednesday filed for a U.S. initial public offering.
Grail was founded by gene sequencing company Illumina Inc (NASDAQ:ILMN) in 2016, with investments from ARCH Venture Partners, Sutter Hill Ventures and Bezos Expeditions, the venture investment fund of Jeff Bezos.
The company, which is developing a blood test to identify early-stage cancers, has set a placeholder amount of $100 million for the IPO, without disclosing the size of its offering.
