Brian Armstrong, the CEO of cryptocurrency trading platform Coinbase, wants to take his company public — maybe on the blockchain.

Onstage at TechCrunch Disrupt SF 2018, Armstrong dished on his ambitions for the future of Coinbase.

“We are self-sustaining,” Armstrong said. “You know, we’ve been profitable for quite a while. We don’t have any plans to raise additional capital at this point, but never say never … Someday I’d love to run a public company.”

Armstrong didn’t rule out going public on the blockchain. He said he’s even considered going public on his own platform.

“I think it would be very on mission for us to do that because, of course, we are creating an open financial system,” he said. “Companies could list their stock, which are really tokens, and instead of a cap table, you tokenize the cap table. But I don’t have any decisions on that to share at the moment.”

An innovative exit would be very on-brand for Coinbase. As one of the earliest players in crypto-mania, the company has certainly had to make things up as it goes. It’s worked, as Armstrong said; the company is profitable and was the first-ever cryptocurrency startup to garner a billion-dollar valuation.

Founded in 2012, Coinbase is backed by IVP, Spark Capital, Greylock Partners, Battery Ventures, Section 32, Draper Associates and more. The company was valued at $1.6 billion in August 2017 with a $100 million Series D last year. The financing was reportedly the largest-ever for a crypto startup.
