Jack Dorsey

ROLE CO-FOUNDERAT SQUAREMENTIONS 9LAST SEEN JUNE 22, 2026
// BIO

Jack Dorsey is a technology entrepreneur and co-founder of Twitter and Square, currently serving as Head (Principal Executive Officer) of Block, Inc., the payments and financial services company Square rebranded to in December 2021. He is best known for co-creating Twitter and for championing Bitcoin adoption in mainstream commerce, including pioneering Bitcoin trading at Square as a public company in 2017 before any regulatory playbook existed. At Block, he has continued to push Bitcoin integration — enabling Lightning Network payments for merchants via Square terminals — while undertaking significant organizational restructuring in 2026 to flatten management layers and pivot the company toward artificial intelligence and agentic workflows.

Do you buy into sort of like the Jack Dorsey view of every company is essentially trying to like build its own little company AGI?

He took three engineers, and he sat at the corner of the sixth floor at 1455 Market and didn't leave the office for three days... The product shipped that Friday night. The accounting and SEC questions got sorted afterwards.

That's probably the biggest takeaway I have from my experience working side by side with him for so long is just like zip it. You don't need to talk. You don't need to put your ideas out there first.

Jack wouldn't leave the office until that product was launched. And so he sat there for a few days and made that happen.

Jack Dorsey recruited Jackie to Square; modeled disciplined silence and listening as a leadership practice; personally led the 72-hour Bitcoin product sprint.

I'm sure you guys have heard Jack Dorsey talk about what he's doing with Block. He basically is trying to turn Block into a mini-AGI around helping people in the world make payments to one another.

Jack suggests every company will have three employee archetypes... The first is the individual contributor or IC... Second is the DRI, the directly responsible individual... The third is the AI founder type.
