Autograph, an nonfungible token (NFT) platform co-founded by professional football player Tom Brady, has raised $170 million in a Series B funding round led by Silicon Valley investors Andreessen Horowitz and Kleiner Perkins.

The startup, launched in July, has also received investments from Lightspeed Venture partner Nicole Quinn and Katie Haun’s new firm. Haun — who recently left a16z, as Andreessen Horowitz is known, to start her own venture — is also joining as a board member, along with a16z partners Arianna Simpson and Chris Dixon, and Kleiner Perkins partner Ilya Fushman.

Brady has been one of the highest profile advocates for cryptocurrencies from the world of sports and entertainment, donning "laser eyes” — a stealth mark among crypto supporters — on his Twitter profile picture.
