Inside Airbnb: The Unorthodox Philosophy Powering 153,000% Growth

In 2007, roommates Brian Chesky and Joe Gebbia had a problem. They couldn‘t afford the rent on their San Francisco apartment. To raise funds, they decided to rent out air mattresses in their living room to visiting designers coming for a conference. They called it the "Air Bed and Breakfast."


Little did they know this desperate act would spawn a company that would upend the entire travel industry. That company is Airbnb, and today it sports some truly staggering numbers:

  • 4 million hosts worldwide
  • Over 7 million listings across 220 countries and 100,000 cities
  • Over 1 billion guest arrivals all-time
  • $38 billion in gross bookings in 2019 alone
  • A peak valuation of $130 billion, more than Marriott, Hilton, and Hyatt combined

By any measure, this is one of the most incredible startup growth stories of all time. Airbnb went from renting out literal air mattresses to becoming the most valuable hospitality brand in just 12 years – 153,000% growth.

So how did they achieve such mind-bending growth? And more importantly, what can we learn from it?

Airbnb‘s Secret Growth Weapon: Jason Bosinoff

To find out, I sat down with Jason Bosinoff, Airbnb‘s Director of Engineering and Head of Growth. He‘s been there since 2011 when the company had just 50 employees. Over the following 8 years, he built and led the growth teams that turbocharged Airbnb into a global phenomenon.

According to Bosinoff, Airbnb‘s dizzying ascent comes down to an almost religious adherence to 3 core growth principles. These have guided every decision, feature launch, and market expansion since the early days.

Principle 1: Build for 100 people who love you, not 1000 who like you

"It‘s about creating 100 passionate evangelists, not just getting 1000 people to kind of like you. Because those passionate early adopters will spread the product for you and pull in the next concentric circles of users over time as the product gets better," Bosinoff explained.

In practice, this meant Airbnb maniacally focused on crafting an incredible experience for its earliest hosts and guests. While other startups chased growth at all costs, Airbnb actually turned away many would-be users in the early years.

"We were rejecting a ton of potential listings because the photos were bad or descriptions were lacking. Our curation really frustrated a lot of people. But it meant the customers we did accept had an amazing experience worth raving about," said Bosinoff.

This patient planting of passionate seeds paid off. Airbnb‘s early users evangelized the service so much that 93% of guests said they found out about it through word-of-mouth or referral. Even back in 2012, 72% of listings that got booked had already been recommended by a previous guest.

Principle 2: Maintain authenticity in everything

Related to the first point, Bosinoff shared that Airbnb has always tried to keep things real and human. This applies to everything from the website design, to the listings, to the brand voice.

"When you go to book a hotel online, you usually see these polished marketing photos that often don‘t match reality. We wanted our site to reflect the uniqueness and realness of every space. So we rely heavily on unfiltered user photos," noted Bosinoff.


This pursuit of authenticity went beyond just aesthetics though. It deeply shaped the entire Airbnb experience:

  • Detailed host profiles let guests get to know who they‘re staying with
  • Two-way reviews after every stay keep both parties honest and accountable
  • Direct messaging makes trip coordination more personal and casual
  • Guidebooks infuse a local‘s perspective you don‘t get from generic travel guides

Even in marketing, Airbnb highlights real traveler stories and un-glamorized user videos rather than celebrity endorsements. "We‘d much rather amplify the voices of our passionate community than manufacture our own," said Bosinoff.

Principle 3: Amazing user experience wins in the long run

The final core tenet of Airbnb‘s growth philosophy is an almost obsessive focus on user experience.

"Many companies get so caught up in short-term tactics and metrics, they lose sight of what really matters – how it actually feels to use the product end-to-end," stressed Bosinoff.

Airbnb‘s growth and product teams collaborate closely to smooth out any rough edges in the user journey:

  • Simplifying the listing creation flow so hosts can get up in minutes
  • Streamlining the booking process with easy filters, wish lists, and one-click booking
  • Handling all payments and security deposits to reduce friction between guests and hosts
  • Providing $1M insurance policy to give both parties peace of mind
  • Offering 24/7 customer support to quickly resolve any trip issues

"We spend an incredible amount of time removing any points of confusion or frustration. For example, we found requesting to book and waiting to hear back could be really anxiety-inducing. So we added instant booking. Small touches like that compound into a magical experience over time," explained Bosinoff.

This fanatical effort has paid off. Despite the radical concept of sleeping in strangers‘ homes, Airbnb‘s guest satisfaction is industry-leading:

  • 84% of guests say Airbnb rentals are as good or better than hotels
  • 91% of guests report being satisfied with their most recent Airbnb stay
  • Guests are 36% more likely to recommend Airbnb than hotels or resorts

Putting the Principles Into Practice

Guided by these principles, Airbnb has unleashed a number of potent growth strategies over the years. Let‘s dive into some of the most impactful…

Referrals: Harnessing word-of-mouth at scale

Airbnb‘s referral program is the stuff of Silicon Valley legend. The premise is simple – invite a friend, and when they book their first trip, you get up to $95 in travel credit.


But the flawless execution has made it a viral juggernaut:

  • 300% more signups from referred users than average
  • Over 50% of bookings in some international markets coming from referrals
  • 10%+ of overall traffic consistently driven by the program
  • Hundreds of millions in revenue generated to date

"We made it insanely easy to share your referral link by text, email, or social media in just a few taps. And we show the travel credit ticking up so you can save toward a specific goal. It pulls people back to the app again and again," said Bosinoff.

User-generated content: Let your community sell for you

Another major unlock has been mobilizing Airbnb‘s passionate users to generate content. Over 80% of Airbnb‘s Instagram photos and videos come from real travelers vs professional photographers.


These authentic shots garner much higher engagement and have become a key funnel for attracting new users:

  • Airbnb‘s Instagram follower growth rate is 3x the industry average
  • Over 50% of Instagram followers end up booking on Airbnb
  • User-generated content drives 3-5x higher click-through rates than branded content

Airbnb also prominently features unfiltered guest reviews on every listing. Before booking, travelers can get an honest assessment from past guests on everything from cleanliness, to accuracy, to host communication.

  • Over 70% of guests leave a review of their stay
  • 85% of reviewed listings maintain a 4.5+ star rating
  • Hosts with 10+ positive reviews get 10% more bookings on average

"Travelers increasingly rely on review platforms like TripAdvisor. We realized those review systems need to be core to the booking experience, not a separate destination. So we invested heavily in making our review system robust, trustworthy and prominent," explained Bosinoff.

Cracking the local code

As Airbnb has expanded to every corner of the globe, localization has been key to unlocking growth in each new market. But this goes far beyond just translating the app and website.

  • Payment methods have to support popular local options like Boleto in Brazil
  • Listing filters need to reflect cultural preferences like Tatami mats in Japan
  • Government IDs have to be checked according to country-specific regulations
  • Customer support must be offered in local languages and time zones

"We learned the hard way that a generic approach doesn‘t cut it. You have to get hyperlocal and embed yourself in the intricacies of each market," said Bosinoff.

This on-the-ground approach has allowed Airbnb to thrive where other American companies have faltered:

  • Over 70% of Airbnb‘s business now comes from outside the U.S.
  • Europe is Airbnb‘s fastest growing market with 4x year-on-year growth
  • Airbnb is #1 in Latin American digital bookings, ahead of major hotel chains
  • China has gone from Airbnb‘s 100th market to 2nd largest in just 3 years

Turning regulation lemons into lemonade

Along the way, Airbnb has faced fierce resistance and legal battles with cities trying to curb short-term rentals. But they‘ve turned many of these challenges into opportunities.

For example, when New Orleans cracked down on unlicensed listings, Airbnb partnered with the city to create an online registration system. Hosts can now easily get permitted directly through Airbnb‘s platform.

"That kind of proactive cooperation turned an adversarial dynamic into a collaborative one. It built trust with the city and removed a major roadblock to our supply growth," explained Bosinoff.

Airbnb has now collected over $2 billion in tourist taxes on behalf of local governments. It has similar licensing systems in place in over 20 major markets. By playing nice with regulators, Airbnb has expanded to places that might have otherwise been off limits.

The Road Ahead for Airbnb

It‘s incredible to think Airbnb has only captured about 2% of its addressable market so far. As it evolves from startup to institution, Airbnb is making big bets to drive its next phases of growth:

  • Experiences: Travelers can now book local activities, events and multi-day trips through Airbnb. This foray into the $180B tours and activities market opens up massive cross-sell potential.

  • Luxury: High-end rentals were Airbnb‘s fastest growing category in 2019, increasing 60% year-over-year. With the average luxury booking over $2000, there‘s huge room to grow this lucrative segment.

  • Hotels: Airbnb now lists boutique hotels alongside homes, diversifying supply in markets with less vacation rentals. Its acquisition of HotelTonight could accelerate this expansion into more traditional hospitality.

"We‘re still in the early innings. Our ultimate vision is to be the one place you go to book anything, anywhere. Not just homes, but experiences, restaurants, flights – we want to capture every part of the trip," said Bosinoff confidently.

With Airbnb poised to finally go public this year, the stakes have never been higher. But if the past decade is any indication, betting against this team would be unwise. Guided by its unorthodox growth philosophy and Bosinoff‘s leadership, Airbnb is well positioned to reshape travel for years to come.
