John Borthwick has spent decades not just investing in the internet but building it himself, from cofounding Total New York and running Fotolog to serving as a Time Warner executive and later rebuilding Digg from the ground up, all while staying rooted in New York's tech scene since the 1990s. That same hands-on instinct shows up in his pattern of backing media infrastructure like Bitly, Chartbeat, Instapaper, and SocialFlow, and in his early involvement with Tumblr, Airbnb, Twitter, Product Hunt, and Hugging Face well before they became widely used.
