Ready to think like a growth hacker? Let’s dive in.


  1. Instagram: Pivot from Geo-Location to Photo Filters Instagram started as a geo-location app called Burbn, but users cared more about its photo filters. The founders noticed this from user behavior and decided to pivot to focus fully on photo sharing. They ditched the location check-in features, making Instagram simpler and more fun to use.


    Heuristic: The decision was based on recognizing a human preference—people wanted quick and easy photo sharing. This shift led to Instagram’s explosive growth and eventual purchase by Facebook.


  1. Hotmail: "PS I Love You" Signature Growth Hack In 1996, Hotmail made one of the earliest viral growth hacks. They added "PS: I love you. Get your free email at Hotmail" to every outgoing email. Every user’s email turned into an ad, which spread the word fast and for free.


    Heuristic: This hack used social proof and the network effect—people naturally shared the service without realizing it. Hotmail grew to 30 million users with no traditional ads and was eventually bought by Microsoft for $400 million.


  1. Dropbox: Referral Marketing Dropbox’s referral program offered free storage to both current users and their friends when they made a referral. This created a viral loop, as users had a clear personal benefit to inviting others.


    Heuristic & Data Analysis: Dropbox tapped into the human instinct to share rewards. They also used data analysis to track how many users were coming from referrals and optimized the system over time, achieving 3,900% growth.


  2. Duolingo: Gamified User Experience Duolingo turned language learning into a game. They added features like streak counts, virtual coins, and leaderboards to make users feel rewarded and motivated to come back.


    Heuristic: This hack relied on gamification, tapping into the human desire for competition and achievement. By making learning fun, Duolingo kept users coming back daily and became one of the top language-learning apps.


  3. Airbnb: Free Professional Photography for Hosts Airbnb offered free professional photography to hosts, making listings look more trustworthy and attractive. High-quality photos led to more bookings, and hosts were able to charge higher rates.


    Heuristic & Data Analysis: Airbnb knew that people are drawn to visual appeal. They also used A/B testing to see how high-quality photos improved conversion rates, helping them differentiate in the crowded short-term rental market.


  4. Costco: Membership Model and Low Prices Costco charges a $60 annual membership fee, allowing them to sell products at much lower prices. The membership creates loyalty, as people feel compelled to shop there to "get their money’s worth."


    Heuristic & Data-Driven: The membership model uses reciprocity—members feel they’re getting a special deal. Costco also uses data to price items like the $1.50 hot dog combo to drive foot traffic and boost retention.


  5. TED Talks: Free Content, Exclusive Events TED Talks grew by offering free videos online while charging over $10,000 for live event tickets. The free content spread TED’s brand globally, while the exclusive events maintained its premium reputation.


    Heuristic: TED combined scarcity and exclusivity with wide accessibility. The free online videos attracted a huge audience, while the expensive, selective events built TED’s prestige.


  6. Apple: Stickers as a Brand Builder Apple includes branded stickers with every product purchase, turning customers into walking advertisements. These stickers became a symbol of loyalty and community.


    Heuristic: Apple used social proof—people love to show off brands they believe in. The stickers increased visibility and created a strong sense of community around the brand.


  7. Netflix: Password Sharing as Viral Growth Netflix allowed users to share their account passwords with friends and family, creating an organic "referral" system. This gave potential customers a taste of the service, and many later converted to paying subscribers.


    Heuristic & Data Analysis: Netflix tapped into the reciprocity heuristic (sharing something valuable). They tracked the data on conversions from shared accounts, proving that this tactic boosted long-term growth.


  8. Facebook: University Exclusivity and Viral Invitations Facebook started as an exclusive network for students at elite universities. To join, you needed a university email. This created demand and curiosity. Once on the platform, users were encouraged to upload contact lists and invite friends.


    Heuristic & Data-Driven: Facebook leveraged exclusivity and curiosity through its restricted access and viral invites. They used data to track how quickly this spread, leading to explosive growth.


  9. Reddit: Bot-Driven Growth Reddit used bots to simulate activity on the platform, making it seem like a thriving community. This social proof attracted real users who wanted to join in on the conversations.


    Heuristic: This hack tapped into the bandwagon effect—people are more likely to join if they think everyone else is already there. Once real users joined, Reddit no longer needed the bots.


  10. LinkedIn: Google Visibility LinkedIn grew by ensuring user profiles ranked highly in Google searches. This allowed users to appear in search results, making their profiles more visible to potential employers and business contacts.


    Data-Driven: LinkedIn’s growth hack leveraged SEO to increase profile visibility. By optimizing for Google search, LinkedIn made every user’s profile act like a digital resume, driving more sign-ups and professional engagement.


  11. Airbnb: Cross-Post Listings on Craigslist Airbnb allowed hosts to cross-post their listings on Craigslist, a platform already popular with people looking for rentals. This hack drove Craigslist users to Airbnb’s site, significantly increasing traffic.


    Technical & Data-Driven: This was a coding tweak that took advantage of Craigslist’s large user base. Airbnb tracked how cross-posting boosted their traffic, using data to optimize the feature.


  1. Google’s PageRank Algorithm: Search Engine Dominance Google’s PageRank algorithm ranked web pages based on their relevance and the number of backlinks they had. This helped deliver more accurate and reliable search results compared to competitors.


    Data-Driven: Google’s growth hack was algorithmic. By focusing on content quality and relevance through PageRank, Google quickly became the most trusted and popular search engine.


  2. Google Ads Quality Score Algorithm: Optimizing For Ad Relevance Google Ads rewards advertisers with higher placement and lower costs if their ads have a high-quality score, which is based on ad relevance, click-through rates, and landing page experience.


    Data-Driven: This algorithmic growth hack incentivized businesses to create better ads, benefiting both users and advertisers. Google used data to ensure that relevant, quality ads got better visibility.

  1. Twitter: Suggested Follows and "Time to Value" Twitter increased user retention by suggesting accounts for new users to follow immediately. Data showed that users who followed 5-10 accounts in their first session were much more likely to return.


    Data-Driven: Twitter’s onboarding optimization reduced the time to value for new users, helping them quickly see the platform's benefits and keeping them engaged longer.


  2. Facebook: Suggested Friends and "Time to Value" Facebook boosted engagement by suggesting friends based on users’ existing connections. By helping new users build their social networks quickly, Facebook made its platform stickier.


    Data-Driven: This onboarding hack reduced time to value by showing users immediate results—connecting with others. The faster users built their network, the more likely they were to stay active on the platform.


  3. Airbnb: A/B Testing Airbnb frequently used A/B testing to make improvements. For example, when they revamped their search page, they ran tests to ensure that the changes improved user experience without harming performance.


    Data-Driven: Airbnb’s A/B testing allowed them to make data-backed decisions to optimize the platform and scale sustainably, ensuring every new feature added measurable value.


  4. ScraperAPI: Fast-Tracking Conversions ScraperAPI doubled its conversion rate by encouraging users to make an API call within 24 hours of signing up. They streamlined their onboarding to make it easier for users to quickly experience the product’s value.


    Data-Driven: ScraperAPI’s onboarding optimization reduced the time to value, helping users quickly see the product’s benefit. This data-backed strategy significantly boosted conversions.


  5. HubSpot: Free Website Grader HubSpot offered a free tool that graded websites and provided insights in exchange for an email address. This helped build a massive email list, which HubSpot used for lead nurturing. It’s still a great tool, and you can access here.


    Data-Driven & Heuristic: HubSpot’s free tool provided immediate value to users while gathering valuable leads. The reciprocity heuristic (give something valuable for free) helped fuel their growth.


  6. Google: Paying Apple for iPhone Search Default When the iPhone launched in 2007, Google paid Apple to be the default search engine. Google realized that if Apple switched to another search engine, they would lose a massive share of mobile search traffic. It appears they were right!


    Strategic & Data-Driven: Google’s partnership growth hack protected its search dominance by keeping its service front and center on iPhones, using data to make strategic financial decisions.


  7. Uber: Surge Pricing Uber used surge pricing to balance supply and demand during peak times. When prices went up, more drivers were motivated to hit the road, ensuring customers could always find a ride.


    Data-Driven: Uber’s dynamic pricing growth hack used real-time data to adjust prices and ensure availability, creating a win-win for both drivers and riders.


  8. PayPal: Referral Incentives PayPal used a simple but powerful growth hack in its early days: $10 for new users and $10 for every friend they referred. This financial incentive created a viral loop, rapidly increasing PayPal’s user base.


    Heuristic & Data-Driven: PayPal’s growth hack tapped into the reciprocity heuristic, offering a clear financial reward. They tracked referral data to fine-tune the program and accelerate growth through user referrals.


  9. YouTube: Simplifying Video Sharing YouTube made video sharing easy at a time when it was technically difficult. Their platform allowed users to upload videos and share them via a simple link, removing barriers to entry and making video content accessible to everyone.


    Technical & Heuristic: YouTube’s growth hack simplified the video-sharing process, creating a technical solution to a common problem. This ease of use tapped into the human desire to share content quickly, driving rapid growth.



  1. Michelin: Stars and Tires Michelin, a tire company, launched the Michelin Guide to encourage more travel and, by extension, more tire sales. They rated restaurants across Europe, encouraging drivers to visit new places and therefore wear out their tires more quickly.


    Heuristic & Strategic: Michelin’s growth hack was heuristic-based, leveraging scarcity and prestige with its star rating system, creating a demand for long-distance travel and indirectly boosting tire sales.


  2. Facebook: "Someone Tagged You in a Post" Facebook’s tagging feature was a major growth driver. When users were tagged in a post, they received an email notification that someone had mentioned them, sparking curiosity and driving them to log in.


    Heuristic: This hack used curiosity and social validation to encourage re-engagement. The more users tagged others, the more viral the platform became, driving continuous growth.


  3. Slack: Optimized Onboarding Slack optimized its onboarding to ensure teams could start using the platform immediately, reducing the complexity of setup. This frictionless experience led to higher adoption rates and word-of-mouth growth.


    Data-Driven: Slack’s onboarding growth hack focused on reducing friction and delivering quick value. The seamless user experience was a key factor in high retention and rapid growth.


  4. Spotify: Freemium and Free Trial Models Spotify offered free access to its music library with ads, while reserving premium features like offline listening for paying subscribers. This freemium model made it easy to attract users and eventually convert them to paid subscribers.


    Heuristic & Data-Driven: Spotify’s freemium model created a low barrier to entry while using data to optimize conversions. Free trials of premium features hooked users, driving long-term subscription growth.


  5. Gmail: Referral Exclusivity and Superior Product Gmail used an invite-only system when it launched, making it feel exclusive and desirable. At the same time, it offered a superior product, with more storage and better features than competitors like Hotmail.


    Heuristic & Data-Driven: Gmail’s exclusivity heuristic created a sense of scarcity and urgency. Combined with data-driven product improvements, this growth hack fueled rapid adoption and word-of-mouth growth.


  6. TikTok: Interest Graph vs. Social Graph TikTok broke away from the traditional social graph model (connecting users based on their relationships) and used an interest graph. TikTok’s algorithm suggested videos based on user interests and behavior, rather than who they were friends with.


    Data-Driven & Algorithmic: TikTok’s growth hack used predictive algorithms to deliver highly personalized content, driving engagement and retention by focusing on user interests rather than social connections.
