Founders

Jack DorseyCo-Founder & Original CEO

Dorsey conceived the idea for Twitter as a short-form SMS-based status update service while at Odeo. He later also co-founded Square (now Block) and served as Twitter CEO twice.

He sent the very first tweet on March 21, 2006: 'just setting up my twttr.'

Noah GlassCo-Founder

Glass was an early collaborator at Odeo who helped develop the initial Twitter concept. He was pushed out of the company early and is often the least-acknowledged of the four founders.

He is credited with coming up with the name 'Twitter' and is largely written out of the popular origin story.

Biz StoneCo-Founder

Stone was a creative director at Google before joining Odeo and co-founding Twitter. He played a key role in branding and culture, later founding other ventures including Jelly and Medium.

He co-founded Medium alongside Ev Williams after leaving Twitter.

Evan WilliamsCo-Founder & Former CEO

Williams was the founder of Blogger (acquired by Google) and brought that experience to Odeo, the podcasting startup that pivoted into Twitter. He served as CEO from 2008 to 2010.

He sold Blogger to Google, then went on to co-found both Twitter and Medium — two of the most influential publishing platforms of the 2000s and 2010s.

How They're Doing

Struggling

X has undergone massive transformation since Elon Musk's $44B acquisition in October 2022, including cutting ~80% of staff, introducing paid verification via X Premium, and pivoting toward becoming an 'everything app.' Advertiser exodus and brand safety concerns led to significant revenue decline, with ad revenue reportedly down 50%+ from its peak. However, the platform retains enormous global reach and remains indispensable for real-time public conversation.

Ad revenue fell sharply following major brand safety controversies and advertiser boycotts in 2023-2024

X Premium (paid blue checkmark) launched as a new revenue stream, replacing legacy verification

Platform traffic remains ultra-high globally with Tranco rank #53, showing resilience in user engagement

Prognosis

Bearish

X is betting its future on becoming a super-app encompassing payments, long-form content, video, and AI through its xAI integration with Grok. The path to profitability is challenging given heavy debt load from the leveraged buyout and ongoing advertiser hesitancy. If Musk can execute on payments (X Money) and AI integration, the upside is substantial, but regulatory scrutiny and competition from Threads remain significant headwinds.

Opportunities

X Money / payments super-app expansion could unlock massive fintech revenue

Integration with xAI's Grok positions X as an AI-native social platform

Video and creator monetization tools could attract influencers away from YouTube and TikTok

Global political influence gives X unique leverage in elections and public discourse

Risks

~$13B in debt from leveraged buyout creates ongoing financial pressure

Continued advertiser boycotts due to brand safety and content moderation concerns

Regulatory risk in EU under Digital Services Act, with ongoing investigations

Threads and Bluesky continuing to siphon users and mindshare
