On 19 January, co-founders Rick Klausner and Hans Bishop publicly launched an aging research initiative called Altos Labs, with $3 billion in initial financing from backers including tech investor Yuri Milner and Amazon founder Jeff Bezos. This is the latest in a recent surge of investment in ventures seeking to build anti-aging interventions on the back of basic research into epigenetic reprogramming. In December, cryptocurrency company Coinbase’s cofounder Brian Armstrong and venture capitalist Blake Byers founded NewLimit, an aging-focused biotech backed by an initial $105 million investment, with the University of California, San Francisco’s Alex Marson and Stanford’s Mark Davis as advisors.
