Growth Hacking Examples of Tech Giants like Amazon, LinkedIn, Zynga, Instagram, and many others

Growth Hacking —

Consider a system external and foreign to you. You don’t control it, you are outside of it, its alien to you, and at times you are at its mercy. You start to observe and learn about it. Then by using your tentacles and the right amount of venom, you start to take over the system. With failed attempts and more learning and observations, you find few points of entry. That’s where you start working and slowly and steadily you crack open the shell.

Hacking can be visualized this way.

In the case of Growth Hacking, it’s the Massive Growth Opportunity that is the system and you are the little creature (growth hacker) trying to hack it.

Sean Ellis, in 2010, coined a term Growth Hacking to explain the data-driven mind-boggling growth in users, revenues and traffic. As per him, the true north of the growth hacker is growth and everything that he/she does is measured by its potential impact on scalability.

One of the finest and earliest examples of growth hacking can be traced back to the launch of Hotmail. Rather than relying on traditional media, they utilized a lean marketing methodology and launched a simple campaign where each email contained the line, “Get Your Free Account at Hotmail”. This simple growth hack led to a massive explosion in the new user acquisition.

Essentially all growth hacking tactics can be termed as lean marketing tactics. All are data-driven, involving low costs tool and tactics. Such initiatives might start from instinct or gut reaction, but are thoroughly investigated, explored, and planned via data.

So, where do you start, what are the main functions that can be used for growth hacking? A better approach could be to look at the case studies of some of the famous growth hacks. This investigation might give you some pointers for the start of the process.

Amazon and eBay — Riding the Explosion of Upcoming Platforms

Both Amazon and eBay scaled when Google launched their Ad platform. In the beginning, not many advertisers were participating in the bidding process, so Amazon bought keywords at dirt cheap prices.

This resulted in getting orders at such low costs that no other channel would come close to it. Later once more advertiser came and the CPC (cost per click) and CPA (cost per acquisition) increased.

Later on, branded term searches and direct traffic of Amazon and eBay made all competitors irrelevant.

This case is an excellent example of riding a wave and capturing the opportunity to its fullest. A new platform was about to explode and by exploiting the opportunity Amazon and eBay became giants.

Amazon was also one of the first ones to crack the email automation, recommending users with products they might be interested in, based upon their search history or buying patterns.

Instagram’s — Early Artists

Instagram started off with the objective of finding the initial influencers to start using their product. Since their product quality is dependent upon the quality of the user-generated data, this growth hack had the potential of getting to early adaptors and also have the best quality content.

So, they contacted (paid? maybe …) 100 artists to post their pics using Instagram on their social profiles like twitter. Such posts carried the stamp of Instagram usage. Their followers learned about the product and saw the potential quality of content. This hack resulted in a massive explosion of growth in user acquisition and within the first few weeks, millions started using the app.

Airbnb and Zynga — Non-scalable Efforts

At times you need to take on projects that can’t be scaled and doesn’t justify the immediate return on investment.

Consider the example of Airbnb. In 2010, they figured out the quality of listing pic makes the end user 2.5 times more likely to buy. So, they started employing freelance photographers to take pics for the listings for free. A massively expensive and difficult task to pursue as they had to scale the team of photographers from 20 to 13,000. Yet, the results were phenomenal and it did pay off well.

Another example of non-scalable efforts to grow business in the long term is of Zynga where the CEO himself declared “F&^K Growth” and focused on improving the quality of game down to each pixel. This resulted in a company-wide perusal of making each and every part of the game work and making use of the entire real estate of the mobile screen to the max. Not only that resulted in the production of great games, but also in increasing customer retention.

Gmail’s — Scarcity Tactics

Gmail did an amazing hack for user growth. For the launch, they would offer the limited invites and that too came exclusively from friends of yours. It became so popular that the in days people were selling invites on eBay for hundreds of dollars. Those who didn’t get the invite were on the waitlist to become a part of the exclusive club.

PayPal and DropBox — Incentivisation

Incentivizing is one of the best approaches utilized by many scalable ventures. The idea is to trade value for the access to the users’ networks.

There could be many ways of doing it. You can unlock premium features of your product for referrals. Games utilize this mechanism well. You can also offer real money. PayPal gave away USD 10 for each referral.

Incentives could be non-monetary in nature too. DropBox gives away more Storage Space for referring a customer. Since they know that the initial usage would result in a later purchase, so they incentivize the potential customer to try it first.


Uber partnered with OpenTable, Uber, and Starbucks by opening their APIs. This helped Uber in accessing the users of other networks.

Evernote has found that 50% of the users of partnered apps are most likely to use their service. So, the act of opening your product to other services via APIs has a major upside to your business.

Remember all partnerships and dependent upon the value you add to your partners’ network. If you are getting access to their customers, you must have a great service to offer in return. At times, that access can come only in return of cash.

Grey Areas and 7 Sins

LinkedIn — Questionable Email Automation

LinkedIn founder Reid Hoffman mentioned one of his hacks where LinkedIn would import a user contact list and keep on sending emails on his/her behalf. This resulted in user growth but can be easily considered unethical. Since there was no formalized penalty for such an act, they utilized it well.

He also believes that for your venture to scale, you need to be playing on the 7 basic sins. So, you might want to go through the list and explore which vice you can scale on.

Airbnb — Questionable Integrations

Airbnb, in the early stage of craigslist dominance, was having issues with suppliers not comfortable listing with them. Their go-to destination was craigslist.

Craigslist didn’t have any API for integration, so the Airbnb made a service that would automatically post the listing on Craigslist to Airbnb.

They did operate in the grey region but were successful in pulling it off and making their venture successful.

Tinder — Hacking Sororities and Fraternities

During the initial days of Tinder, one of their marketing head employed an ingenious way to scale and engage. She started visiting the campuses and would to sororities and convince them to upload their profiles to be found. Then she would go to fraternities and convince them to do the same.

This way she was able to tap into the highly motivated users of the platform — the early adaptors. The consumers of the app started seeing the value it offered right away. Truly, one of the best hacks to engage early adapters.

Uber — Campuses and Social Invites

Uber did a similar hack to Tinder and used early adaptors from campuses. They offered students flat rates from college to downtown areas.

One of the best campaigns that Uber used was the Social Invite to friends. Once you share the coupon with your friends and end up downloading the app and taking the ride, you get a ride for free.

Similar tactics were utilized by players like Careem in other markets to exponentially grow their user base.

Zynga — Ideation Hack

For idea generation and testing, Zynga employed a technique where they would show the users the banner of new game ideas.

In case a certain percentage clicked on the banner and shared their info to be notified later, they determined which idea has merit or not. This resulted in gathering data from the already acquired user and also determining which next project to work on.

Instagram — Simplest of Hacks

One of the biggest hassle Instagram faced during its early years was its server downtimes. Once they fixed that part they were able to provide a better service. That’s why the CEO and founder commented that the Better Performance in itself is one of best hacks you can employ.

LinkedIn — A Better Network

LinkedIn did imply great growth hacks to make their network more useful for its users. Their widget with the suggestions of friends of friends resulted in explosive growth. It also made the network more useful for everyone.

Etsy — Killing its own Growth Hack

Consider the case of Etsy, the company listened to their customers and they wanted an infinitely scrolling page so that their products can be viewed without the delay or hassle of clicking next page button.

Etsy implemented the infinite scrolling with 5 months of tech development. Later they found out that the conversion rate has decreased significantly. So they had to let go of the project and went back to the original pagination mechanism.

A good example of relentless perusal of growth and having the discipline to kill your own (in this case customers’) ideas.

Groupon — Growth Hacking Gone Wrong

For acquisition, you can also look for virality.

Remember Groupon, one of the best examples of venture going viral. Yet this single-minded obsession took away their focus on user retention and that resulted in huge loses to the company later on.

Remember, growth Hacking can be tricky and beware of a single-minded obsession of pursuing one objective and missing the whole picture.

Summing Up:

I hope you get an idea of growth hacking potential and also its complexities.

Remember, all examples of hacks were very specific to the company, their own capabilities, and the situation they were in. It might or might not work for you.

In the next article, I will discuss the steps you can take to make it work for you. The focus will be on Customer, Product, Data, and Tools.
