How Jack Dorsey evolved as a leader at Square, preparing him to save Twitter
Why Jack Dorsey Is Ready to Save Twitter — On a fall day in 2010, Jack Dorsey stepped before his staff at Square, his payments startup, to deliver a pep talk at its weekly all-hands meeting.
Context & Ripple Effects
This profile lands one day before Twitter's board decision: after months in which Dorsey told confidants he would refuse to give up the Square CEO job during IPO preparations, he is presented not as an interim caretaker but as a leader whose management style was rebuilt at Square. The arc runs through his own account of running Square — using data to cut risk and lift margins, with Caviar giving the payments company visibility inside restaurants (his data-driven margin playbook).
The stakes were real on both sides: Bloomberg had reported that Square's IPO bankers were building contingency plans in case Dorsey left for Twitter full-time. The next day's announcement resolved it by refusing to choose — Dorsey got both jobs, Adam Bain moved up to COO, and Dick Costolo exited the board.
First-order effects
- Twitter gains a permanent CEO who frames Square as his leadership laboratory, with Adam Bain installed as COO to run operations beneath him.
- Square heads into its IPO with a dual-CEO arrangement its bankers had explicitly hedged against, leaving investors to price founder attention risk alongside the offering.
Second-order effects
- Bain's promotion makes the COO role the structural answer to the split-focus question — Twitter effectively hires an operator so its CEO can be shared.
- Square's IPO story now hinges on whether Dorsey's presence helps or hurts the roadshow; the contingency planning suggests underwriters saw real downside scenarios worth pricing.
Third-order effects
- If the dual-role bet holds, the 2015 framing ages well: Square's subsequent performance and rising stock had it approaching Twitter in value by late 2017, vindicating the keep-both-jobs structure — but the same pattern also normalizes founder CEOs splitting attention across companies as a governance model rather than an exception.
The trend: Founder-led companies are normalizing the dual-CEO experiment, betting that operational depth from a lieutenant like a COO can offset a founder's divided attention.
