Altos Labs, Inc. is an American biotechnology research company. Altos Labs’ goal is to develop life extension therapies that can halt or reverse the human aging process. Specialized cell therapies based on induced pluripotent stem cells are to be developed for this purpose. The company was started in 2022.

One of the early investors of Altos Labs is an investment vehicle held for the benefit of the Breakthrough Foundation, founded by Russian-Israeli science and technology investor and philanthropist Yuri Milner and his wife Julia. The foundation supports existing and future philanthropic projects in fundamental sciences.[4] Milner had previously shown interest in anti-aging technologies, in October 2020, he co-hosted a meeting where experts presented their research, reported on animal testing, and the concept for Altos Labs was developed.

Altos Labs raised $3 billion in a funding round from investors in January 2022.[2] It is said to be the best funded biotech start-up to date.[3] Investors reportedly included Amazon founder Jeff Bezos.[5]

23andMe Holding Co. is a publicly held personal genomics and biotechnology company based in South San Francisco, California.  It is best known for providing a direct-to-consumer genetic testing service in which customers provide a saliva sample that is laboratory analysed, using single nucleotide polymorphism genotyping, to generate reports relating to the customer’s ancestry and genetic predispositions to health-related topics. The company’s name is derived from the 23 pairs of chromosomes in a diploid human cell.

The company had a previously fraught relationship with the United States Food and Drug Administration (FDA) due to its genetic health tests; as of October 2015, DNA tests ordered in the US include a revised health component, per FDA approval. 23andMe has been selling a product with both ancestry and health-related components in Canada since October 2014, and in the UK since December 2014.

In 2007, 23andMe became the first company to begin offering autosomal DNA testing for ancestry, which all other major companies now use. Its saliva-based direct-to-consumer genetic testing business was named “Invention of the Year” by Time in 2008
