Tech Crunch: Eight Sleep, which makes “smart” mattresses that use artificial intelligence-based algorithms to improve sleep both by changing temperature and monitoring other physical parameters, has raised $86 million in a Series C round of funding.

Valor Equity Partners — the firm that has backed the likes of Tesla, SpaceX, GoPuff and many other big tech firms — is leading this latest investment, with SoftBank, Khosla Ventures, Founders Fund and General Catalyst also participating, along with a lot of high-profile individuals who are also users of the product: athletes Alex Rodriguez, Kris Bryant and J.D. Martinez; celebs Kevin Hart; and tech figures Sophia Amoruso, Naval Ravikant and Kyle Vogt.

This Series C brings the total raised by Eight Sleep to $150 million, and the startup has confirmed to me that its valuation is now close to $500 million.
