He previously served as CEO of Twitter, Inc. and sat on its board of directors. Jack's Twitter Score is 1000 out of 1000 (an Excellent rating) as of July 2026, placing him at rank #1 (top 0.1%) of 389,587 accounts tracked on this platform, above the 36 accounts that score above 900.

Jack is a prominent Bitcoin advocate whose work at Block, Inc. centers on bitcoin-focused products including Cash App (BTC trading), Bitkey (a bitcoin hardware wallet), and Proto (bitcoin mining hardware). Block led a purchase of 4,709 bitcoins for $50 million in October 2020 and expanded those corporate holdings further in 2021. The company rebranded from Square to Block in December 2021 citing blockchain interest, changed its NYSE ticker from SQ to XYZ in January 2025, and was added to the S&P 500 in July 2025. In November 2024, Block announced it was winding down its TBD bitcoin developer unit to refocus on bitcoin mining and Bitkey, and in February 2026 it announced layoffs of over 4,000 of approximately 10,000 employees, citing artificial intelligence; Block shares rose 24% following that announcement.

Jack has directed resources toward multiple decentralized technology projects. He provided a 14-bitcoin grant to Fiatjaf, creator of the Nostr decentralized social protocol, in 2023 and seeded the OCEAN bitcoin mining pool in 2023, aimed at decentralizing mining block-template selection. In July 2025, he launched Bitchat, a peer-to-peer messaging app using Bluetooth mesh networking and the Nostr protocol. Jack announced the Bluesky decentralized social-media initiative in December 2019 while serving as Twitter CEO, joined its board in February 2022, and left the Bluesky board by May 2024, endorsing X as freedom technology. He retained a 2.4% Twitter stake that rolled into Elon Musk's X Holdings when Twitter was acquired in October 2022.

Jack and Block, Inc. have drawn regulatory and legal scrutiny. Hindenburg Research disclosed a short position in Block on March 23, 2023, alleging inflated user metrics, compliance failures, and facilitation of fraud on Cash App. As of May 2024, federal prosecutors in the Southern District of New York were reported to be examining Block financial transactions and compliance practices, following whistleblower allegations of sanctions and AML lapses at Square and Cash App. Media has also speculated that Dorsey may be Bitcoin creator Satoshi Nakamoto; no proof has established this claim.

Jack's portfolio of associated holdings includes Celo, CoinList, Lightning Labs, Azteco and OCEAN.
