How Laura Modi built a cult-like brand with Bobbie infant formula

Executive overview

The US infant formula market is a duopoly that hadn't changed in 40 years. Laura Modi, a former Airbnb director, founded Bobbie after becoming a mother and finding every existing formula embarrassing, guilt-inducing, and scientifically outdated.

She built a brand by solving the emotional problem parents actually have — feeling like they've failed — rather than competing on product specs. During the 2022 formula shortage, she turned off Bobbie's website for six months to protect existing subscribers, a decision that cemented brand loyalty and made Bobbie the only formula company that never ran out.

The core insight: brand is 60% of growth — a great product that parents believe in generates word-of-mouth that no paid marketing can replicate.

Lessons from Airbnb

• The real product at Airbnb was the hosts, not the technology — a shift that only happened once the whole culture accepted it.
• Growth follows when you put the supply-side user first and build tools for them, not for internal metrics.
• Energy is the currency of a high-performance culture — keep it going deliberately.
• Storytelling, even for small features, makes people feel they're having large impact and drives cross-functional alignment.
• Personal connections matter in remote companies — build in time for personal as well as professional check-ins.

Founding Bobbie

• 83% of US parents use formula, yet the product made them feel guilty and looked medical, not like food.
• The market was a duopoly with no meaningful innovation in ~40 years.
• Laura had no infant formula background — she saw the problem purely as a new mother and a business-minded operator.
• She spent significant time researching viability, financial runway, and market conditions before leaving Airbnb — the "overnight leap" took years of preparation.

The formula shortage and sloth strategy

• In 2022, a competitor recall caused a national formula shortage; Bobbie's subscriber count doubled in a week.
• Head of growth identified that inventory would run out in six days at that pace — existing subscribers would be left without product.
• Decision: shut down the website, stop all new customer acquisition, protect the 70,000 existing subscribers.
• The site stayed off for six months; the team was renamed the "sloth team" and tasked with the opposite of growth — including emailing subscribers to encourage cancellations to manage supply.
• Outcome: Bobbie became the only formula company that reliably served its customers throughout the shortage, generating lasting brand loyalty.
• Storytelling the impact back into the company — including a moment at Davos where a subscriber approached Laura in tears — kept morale high despite zero growth.

Brand building

• Connect brand to the top three things your customer is worried about; don't create noise around problems they don't have.
• Bobbie's positioning addresses the guilt and stigma around formula feeding directly, rather than attacking breastfeeding advocates.
• Never point fingers at competitors or alternatives — only talk about what your product does and why it exists.
• Brand internal projects and workflows: named programs (Project Shamrock, Project Lumberjack, the Secret Shopping compliance program) create memory, motivation, and recall far better than bland process names.
• Milkdrunk, a separate content platform, was built five years ago as an SEO play; it now ranks between the CDC and The Bump on searches like "how long does formula last."

D2C growth strategy

• "D2C is not dead — the approach people used is dated." Reliance on paid marketing is a drug that gets more expensive over time.
• Framework: flip the order from commerce → content → community to content → community → commerce.
• 60% of growth comes from product and brand; 40% from distribution and word of mouth.
• Airbnb's COVID decision to cut paid growth entirely is the rare proof that you can get off the drug — crises can be the forcing function.

Hiring for naivety and momentum

• An ounce of naivety is the biggest secret to success: it preserves creativity, whitespace, and willingness to question the status quo.
• Laura's head of marketing is an Emmy-winning news anchor with no traditional marketing background — she operates Bobbie's marketing more like a media company.
• Red flag in interviews: candidates who question their lane or say "I don't do that."
• Hire optimistic doers — people who move fast, make decisions without needing certainty, and don't confuse strategy with output.
• Avoid "intellectual ejaculation" — big ideas without execution.

Manufacturing momentum

• A leader's job is not just to sustain momentum but to manufacture it.
• Fake deadlines work: set a launch date (e.g., May 1st) even without a hard reason — the constraint forces execution.
• Name and brand milestones so they create recall and energy across the org.
• Favorite interview question: "Teach me something" — unrelated to work; tests ability to explain ideas clearly and reveals curiosity and personality.

Operational infrastructure for founders

• Building a startup while raising three kids with a co-founder spouse requires treating home operations like a company: weekly agenda meetings, shared calendars, explicit trade-offs on childcare and commitments.
• Support infrastructure — EA, nanny — should be celebrated as core leverage, not hidden.
• Async-first work culture reduces meeting overhead; one-hour Slack sprints with 20 people can replace a meeting and produce a decision.
