Jessica Ellerm continues her look at fintech growth hacks for a further three familiar businesses in the last of this two-part series.

In part one of my two-part growth hacking series, I covered how PayPal, Mint and Acorns all supercharged their growth by applying some achievable growth hacks to their customer acquisition strategies. This week, I’m looking at Robinhood, Blueleaf and Stripe.

Remember: growth hacking is always underpinned by a solid growth strategy to begin with. They’re like the cherry on top of the proverbial cake.

HACK #4: Share-trading app Robinhood’s social powered 1m+ waitlist

The problem that needed solving

Let’s face it, on your own you can only drive so much traffic to your site. But imagine if you had an army of people, sharing links back to your product landing page for free? Mobile trading app Robinhood worked out how to do just that by offering priority access to its app in return for waitlist subscribers sharing a link to their friends and social networks.

The hack

Before the product was launched, there was little Robinhood could offer in terms of a tangible kickback to waitlist users if they were to share the landing page. They decided to gamify the promotion of the landing page itself. Tracking social shares via a unique referral url, Robinhood was able to bump the original referrer up the waitlist for every additional ‘friend’ that signed up.

This hack can be traced back to online shaving company Harry’s Razors, which stored the original code on GitHub. Believe it or not, you can now get the entire waitlist generator and referral tracking tool out of the box over at KickoffLabs. I’m using a variant of it right now for a promotion I’m running giving away two Brett King books. The tools are out there!

Why it worked

Gamification taps into our competitive nature. By leveraging the principles of social proof – Robinhood showed the waitlist total on the thank you page – it gave people confidence to share the link with their friends (ie others think this is of value, therefore it must be). The landing page design was also simple, the share buttons were prominent and the copy was direct.

The results

According to an early review by Sean Ellis on, Robinhood was generating around 50% of new signups via the tracked links. That’s traffic back to their site they weren’t paying a cent for.

HACK #5: Blueleaf’s limited time invite offer

The problem that needed solving

Creating an aura of exclusivity can make people want your product even more. Financial advice platform Blueleaf realised adding a dash of friction alongside a time-bound incentive into its customer acquisition process could drive new user acquisition. How’s that for a little reverse psychology!

In order to do this, it needed a compelling call to action that made users sign up today rather than tomorrow. A landing page on its own just wasn’t going to cut it. It had to find some other way to build urgency into its signup and referral strategy.

The hack

Blueleaf decided to make it ‘just hard enough’ to get access to its product. It did this by having only two ways new users could get access to the list: either by receiving an invite directly from the company or from a current user.

To receive a direct invite, you had to show you wanted the product by following the company on social media, and then by publicly requesting one, thus spreading the word in the process.

Current users could only send out invites during specified times. Blueleaf would publicise the invite hours, then wannabe users would again post on social media that they were looking for an invite, or contact users they knew who were already in.

Why it worked

The hardest thing about boosting conversion is creating the urgency to convert now rather than later. Blueleaf nailed this with its invite hours.

Creating a sense of intrigue among its audience also helped drive traffic back to the site. When new users saw those ‘in the know’ posting on social platforms requesting access, curiosity got the better of them, making them click through to the website to find out what it was all about. A viral loop was born.

The results

Using these tactics, Blueleaf built a list of 10,000 users before it launched.

HACK #6: Stripe’s grassroots campaign

The problem that needed solving

Generating word of mouth is possibly one of the hardest nuts to crack when you’re starting out. But if you can get the experience right for the first 100 to 200 customers, the amplification effects from those happy customers out to their network can be huge. That’s what payments startup Stripe did, by focusing time and energy on the developer community.

Early on, Stripe realised that developers using its payments API were so enamoured with the product, they couldn’t help but tell their friends about it. It set about trying to grow the organic referral behaviour in the early base.

The hack

Stripe employed grassroots advocacy hacks, such as sending care packages to developers whose Stripe instances went live, including T-shirts, stickers and other Stripe-branded ‘swag’. Next thing, developers were sharing their Stripe goodies on Facebook and Twitter, organically spreading the word.

According to this post over at GrowthHackers, Stripe embedded itself into the dev community, sponsoring hackathons, meetups and developer events, all aimed at building a buzz around the company and ultimately the product.

Why it worked

Stripe ‘got’ its target audience, taking a grassroots approach that put aside flashy marketing and gimmicks in favour of personal touches and ‘pressing the flesh’. None of it would have mattered had it not built a solid product with great documentation that was better than anything available at the time. But firing up people who were already loving the experience, and giving them reasons to share, helped propel Stripe to where it is today.

The results

Industry sources put Stripe’s current global payments volume at about $20bn a year.
