How Morning Brew Built 8 Professional Audiences From One Consumer List

In 2015, Alex Lieberman and Austin Rief were students at the University of Michigan when they started emailing a short business news summary to classmates. The early version was a PDF called Market Corner, with clip art of a bull and a bear on the cover. They raised $750,000 in 2017, barely spent it, and never raised money again. The daily newsletter funded everything.

By 2020, the flagship had grown into a profitable advertising business. In October of that year, Insider acquired a majority stake in a deal that valued the company at $75 million, when Morning Brew was generating around $20 million a year. Much of the list came from a referral program that rewarded readers for bringing in friends. The newsletter now reaches more than 4 million free subscribers, has open rates above 50%, and reportedly generates more than $70 million a year.

The Flagship Sold to a Broad Audience

The daily newsletter covered business and the economy in a light voice aimed at working millennials. Advertisers paid to reach that audience, priced on how many people opened each send. The audience was broad by design, and a single brief served marketers, engineers, nurses, and analysts alike. That breadth built scale. But reaching one specific kind of professional through it was harder.

The Consumer List Became a Source of Professionals

Within 4 million general readers were the finance people, marketers, HR leaders, and technologists that advertisers wanted most. Morning Brew began identifying readers on its list and moving them into newsletters tailored to their work. The company calls this cross-pollination. A reader of the daily brew who shows signs of working in finance can be pointed toward CFO Brew. The same person who was worth a general impression becomes worth much more once identified as a finance executive and placed in a finance product.

That mechanism runs the whole B2B business. Most professional newsletters start their audience from zero. Morning Brew started each one with a large pool of readers who already knew the brand. CFO Brew launched in 2022. Around it sit 7 more titles covering marketing, retail, HR, IT, healthcare, technology, and founders. The technology brand now operates as Tech Brew, having launched as Emerging Tech Brew. Together, the 8 form a franchise of separate audiences drawn from the same list.

Each Vertical Carried Its Own Advertisers

The reason to build 8 audiences comes down to who pays for each. A finance software company, a healthcare vendor, or an enterprise IT platform wants a room of the exact buyers for its product, and it pays accordingly. A specialist newsletter delivers that. The advertisers in CFO Brew barely overlap with those in Retail Brew or Healthcare Brew, so each vertical opens a distinct pool of spending.

The professional side also sells more than newsletter placements. A former head of the division has said only three of the company's dozen or so B2B ad products are related to the newsletter. The rest are lead generation, webinars, and events. Professional readers download reports, register for webinars, and attend conferences, and advertisers pay a premium for those actions.

The B2B Division Grew Toward the Size of the Flagship

The professional division reportedly generated around $25 million in 2024, up from under $5 million about four years earlier. By the company's own account, it went from zero to $25 million in five years. Management has said it expected the division to surpass the flagship daily newsletter in revenue. 

Each new vertical launches into an existing audience, so it reaches revenue faster than an independent startup on the same beat. The daily newsletter incubates the vertical, and shared sales, data, and technology teams carry it afterward.

Where Morning Brew Stands Now

Austin Rief finished a decade-long run in early 2025, and Robert Dippell became chief executive with B2B media experience from Bisnow and the audience-data platform Omeda. The flagship remains large and profitable, and the company has expanded into podcasts, video, and creator shows. The center of the business is the professional division. Morning Brew started with one broad audience and learned to identify the specialists inside it. That work turned a single consumer newsletter into a business media company that sells to 8 professional audiences, each served by a separate set of advertisers.

Morning Brew built a second business out of the audience it already had. The daily newsletter reached more than 4 million general readers, including the finance leaders, marketers, and technologists that specialist advertisers most wanted to reach. The company developed a way to identify those readers and move them into newsletters tailored to their work. Each of those newsletters arrived with its own set of advertisers, and those advertisers paid more to reach a room of exact buyers.

The same pattern is open to any media brand sitting on a large general audience. Most publishers treat that audience as a single product and sell it to a single kind of advertiser. Inside it are dozens of professional segments, each of which a different set of advertisers would pay a premium to reach. A news brand holds doctors, lawyers, engineers, and financiers. A sports brand holds coaches, marketers, and team executives. A consumer brand holds the operators who run the industry it covers. Each segment can become its own product with its own audience and its own advertisers, and each one starts with readers the company already has. See you next week.
