Lieberman announced he is building a second media company — Tenex Media — described as a digital destination for AI education and applied AI content, with an editorial newsletter called Ultrathink and plans to hire founding AI creators.
He walked through a live demo of his AI-driven content system — including an 'Oracle' for idea sourcing, voice/style files, and an editorial council — framing it as a repeatable model for founder-led content at scale.
A mainstream feature covering his full founder arc — from selling Morning Brew for $75M to co-founding Tenex and Storyarb — with candid commentary on how AI amplifies strong operators and hurts weak ones.
Lieberman publicly announced the Tenex Labs x Vercel partnership, noting Vercel had been a key infrastructure partner dating back to his Morning Brew days.

Alex Lieberman is a New York-based entrepreneur best known as co-founder of Morning Brew, the business-focused daily newsletter he built from a University of Michigan side project into a multi-million subscriber media property before its acquisition by Insider Inc. in 2020. Since that exit, Lieberman has pivoted toward artificial intelligence as co-founder of Tenex Labs, and his content has shifted accordingly — from broad startup commentary to hands-on guidance on helping companies move from AI-absent to fully AI-native operations.
His social audience skews young and predominantly male — early-career founders, operators, and tech-adjacent professionals concentrated in major English-speaking markets. That composition aligns well with his sponsor mix: AI-native platforms like HyperAgent and Profound sit alongside mainstream brands such as TurboTax, suggesting he bridges credible operator content and broadly accessible business advice. With AI adoption still in its early mainstream phase, Lieberman's practitioner framing — grounded in a documented media exit and active company-building — positions him as a trusted voice for brands targeting ambitious professionals who are actively evaluating and deploying emerging technology.
Alexlieb reaches an audience concentrated in United States primarily through YouTube, and is best activated via Instagram Reels and Stories. Their sponsorship history skews toward Media / Newsletter, AI / Tech, Finance / Software, a clear signal of fit for brands in those categories. Demonstrated partners include Morning Brew and TenEx Labs. Engagement on YouTube runs around 1.4%, which points to an audience better suited to category-relevant, mid-funnel campaigns than to pure-reach buys. Their YouTube-first format lends itself to integrations that sit inside the creator's usual content rather than running as standalone ads. Because the audience follows tech content rather than arriving through untargeted reach, sponsorships that match the channel's subject matter tend to convert more efficiently than broad placements. A consistent, on-topic posting focus gives sponsors a predictable, brand-safe environment, lowering placement risk compared with broad, general-interest channels. Campaigns here are best measured on qualified engagement and consideration within the niche rather than on raw impression volume. For United States-focused brands in Media / Newsletter and related categories, Alexlieb offers a defined, creative-fit audience rather than broad, low-intent impressions.

Morning Brew was acquired by Insider Inc., the parent company of Business Insider, marking a major exit for Lieberman and his co-founder Austin Rief.

Tenex Labs is the AI startup Alex Lieberman co-founded after Morning Brew, focused on helping businesses shift from AI-absent to fully AI-native operations. The company's mission directly shapes his content, which is largely dedicated to practical AI adoption strategies for founders and operators.
AI-native is Alex Lieberman's term for businesses that have embedded AI into their core workflows rather than just layering AI tools on top of existing processes. His Instagram and YouTube content consistently breaks down how founders and executives can make that structural shift.
Following Morning Brew's acquisition by Insider Inc., Lieberman stepped away from active leadership at the company. He has since focused on Tenex Labs and building an audience as a creator in the AI and startup space.
