Morning Brew: newsletter subscriptions sold for $75m

The founding and history

Morning Brew was founded in 2015 by Alex Lieberman and Austin Rief while they were both undergraduates at the University of Michigan's Ross School of Business. The founding insight: business and financial news (Wall Street Journal, Bloomberg, CNBC) was written for an older, established audience; a newsletter written for college students and young professionals in a conversational tone could capture an underserved audience.^[1]

Lieberman and Rief built the newsletter from the dorm room with patience — the first year focused on growing organic subscribers among Michigan students and via word of mouth on college campuses. The voice was deliberately conversational, witty, and concise; the format (daily morning email at 6 AM ET) created a habitual reading pattern.^[2]

The playbook executed

Morning Brew's growth playbook layered three motions: referral program (subscribers earned merchandise and perks for referring friends — the SparkLoop referral system became widely emulated by other newsletter operations), brand partnerships (newsletter sponsorships sold directly to brands like Microsoft, Robinhood, Square, and dozens more), and spinoff newsletters (Marketing Brew, Retail Brew, Tech Brew, Emerging Tech Brew expanded the franchise into vertical-specific newsletters).

The unit economics were unusual for media: newsletter sponsorships at $20-$40 CPM produced significant revenue per subscriber per year; the subscriber acquisition cost via referral program was meaningfully lower than paid acquisition would have been; the daily-habit format created retention that traditional media subscriptions couldn't match.^[3]

The results

Insider Inc. (now Business Insider) acquired Morning Brew in October 2020 for $75M — at the time one of the largest newsletter acquisitions. The acquisition validated the email-newsletter business model and triggered a wave of subsequent newsletter brand launches (The Hustle, Workweek, Industry Dive's expansion, and the broader Substack ecosystem).^[4]

By 2024-2025, Morning Brew continued growing under Insider ownership with 4M+ daily subscribers and expanded media properties including podcasts, video content, and event/conference business.

What this case study teaches

• Voice and audience-specific positioning beats generic content — Morning Brew's tone for young professionals was structurally differentiated.
• Daily-habit formats compound retention — morning email at 6 AM became part of subscribers' morning routine.
• Referral programs at scale are the cheapest acquisition — the SparkLoop-style merchandise referral became the modern newsletter playbook.
• Vertical expansion reuses the brand and audience — Marketing Brew, Retail Brew, etc., leveraged existing Morning Brew distribution.
• Email newsletter economics work better than they appear — sponsorship economics at $20-$40 CPM compound across millions of subscribers.
