Veteran venture capitalist Ron Conway announced on Friday that he has been “recently diagnosed with a rare cancer type.”

In a message on X, Conway stated that he “will be stepping back from some of my regular activities,” but he plans to “continue supporting” the founders associated with his firm SV Angel: “With a more concentrated and balanced agenda, I can focus on treatments while assisting SV Angel founders at critical junctures as we always do!”

Conway further mentioned that SV Angel will remain “unchanged,” noting that his son Topher Conway “has been making all of our investment choices for most of the last decade.” He also highlighted that another son, Ronny Conway, became a managing partner in 2024.

“They bring knowledge from nearly every significant technology cycle in Silicon Valley and are currently dedicated to collaborating with founders shaping the future of AI,” Conway remarked.

He added that he is not disclosing “the particular type of cancer” in his diagnosis to avoid “speculation” regarding the prognosis, yet he expressed that he remains “optimistic.”

“I am fortunate to have an amazing team of UCSF doctors in San Francisco, and as you know, I never back down from a battle,” Conway stated.
