How the Harry’s Referral Program Got 100,000 Sign-Ups in One Week

The Harry’s pre-launch referral program is one of the most studied examples in referral marketing — and for good reason. Before their product was ever available to buy, they collected over 100,000 email sign-ups in a single week. More than three-quarters of those came from referrals.

This wasn’t luck. It was a deliberately designed system: the right reward structure, messaging that made sharing feel generous instead of transactional, and a loop that kept spreading on its own.

Here’s how it worked — and what you can take from it for your own program:

• Harry’s built their referral program around giving, not earning — framing referrals as a gift to friends drove far more sharing than a straight reward play would have.
• Treating the program like a campaign was both Harry’s biggest strength (the pre-launch buzz) and their biggest mistake (they stopped after launch and missed ongoing referrals).
• Tiered rewards with an achievable first tier (just 5 referrals) are what drove Harry’s high participation — the reward felt within reach from day one.

Harry’s referral program: How it began

Harry’s is a simple, yet high quality, razor brand that is famous for its razor shave club subscription. In fact, Harry’s is one of the most successful razor subscription brands on the market (alongside their competitors, Dollar Shave Club). 

Harry’s has since become a household brand, and since it falls in a very niche market, it seems to be quite popular when compared to what’s in the mass market. The bright orange handle (though it’s not the only option available) is recognizable by even people who aren’t using the brand. Their team of 600 engineers, chemists, and designers really seem to have knocked this one out of the park. They have since expanded to a variety of care products, like deodorants, skincare, soaps, and shampoos.

Aside from their signature look, many consumers choose Harry’s because they give back to the community. 1% of all sales gets donated to nonprofit organizations that offer mental health services to men. They are set to reach $12 million in donations (helping about 1.5 million men) by 2024.

But, how did they get to this point? Their prelaunch really helped set them off. They managed to receive over 100,000 emails in just one week of this prelaunch campaign.

Their prelaunch was set up to focus specifically on valid referrals. So, the founders Jeff and Andy, took it upon themselves to meet up with friends and other entrepreneurs they knew to get help sharing their product. About 200 people later, they were ready to focus on using these contacts to spread the word via their referral campaign. 

This campaign proved to be a success:

• Referrals accounted for more than half of all signups! 77% of the 100,000 emails collected came from referrals. 
• 20,000 people sent a referral. There were roughly 65K referrals sent. 
• 200 people sent more than 50 referrals. Meaning, 200 people actually made it to the highest tier.

Let’s take a deeper look into their prelaunch and referral campaign.

How does the Harry’s referral program work?

The Harry’s referral program used a milestone – or tiered – prelaunch program structure. At certain tiers a new reward would be up for grabs.

For the initial push, the program was promoted by all employees. At the time, employees were encouraged to send the product announcement to their friends, family, and anyone else they knew (referrals started from the very start!)

The email sent was personalized and friendly – plus, who wouldn’t open an email from a friend? This email would provide a link to the Harry’s 2-page microsite, where the referral would find a splash page (to sign up), and then the referral page (the viral loop).  

The referral page included easy sharing options and a progress bar to track referrals and reward status. Each tier was laid out so that a free product was awarded. The lowest tier, 5 referrals, awarded a less expensive Harry’s product (free shave cream), and the value went up at each tier. Ultimately, the reward at the fourth tier, 50 successful referrals, was an entire free year of shaving blades.

The Harry’s viral loop: How it spread

By starting with employees, Harry’s reached people in a personal, friend-to-friend way. They didn’t need press or traditional advertising — at least not to get the initial momentum going.

A viral loop is what happens when people share a brand with friends, who in turn share with their own friends, creating a cycle that feeds itself. Harry’s built this deliberately. It allowed them to tap into the trust that already existed in their network — starting from their own team and working outward. This type of acquisition is free or nearly free (the only cost is when a referral actually converts).

What kept the loop moving was how Harry’s structured the rewards. Referrals could start sharing immediately upon signing up. The more referrals they sent, the higher the reward tier they could reach — which encouraged people to refer more than one friend. This multiplying effect is what produced numbers like 200+ people reaching the 50-referral tier.

Harry’s encouraged both customer acquisition and retention by investing in their existing network first. Then used the product itself to make people want to participate. Together, those two decisions drove their viral growth.

What made the Harry’s referral program work?

Let’s break down each element that helped Harry’s reach 100,000 subscribers in one week. We’ve got plenty of pointers for your own referral program that you can steal. 

Strategic first invitations

The Harry’s pre-launch program used a strategic invitation approach to build buzz and generate excitement for their product launch. In addition to having employees share, they offered an exclusive sneak peek to a select group of influential individuals, and encouraged them to share the news with their audiences. (This included fellow CEOs.)

By targeting this group, Harry’s was able to leverage their social influence and credibility to reach a wider audience and generate interest in their brand. They also made it easy for these individuals to share the news by providing them with pre-written templates.

The emails used to announce the impending launch were created very strategically by:

• Relying on employees. Employees personally invited the recipients to share with their own peers, in a conversational, friend-to-friend way. People trust those they know – so it made sense to go this route.
  • All invites had email signatures with a direct link to the program.
• Providing personalized messages. All emails sent were personal invites and used a conversational tone.
• Very tailored content. Messages to each invitee was based on how much they knew (or didn’t know) about Harry’s.
• People with a direct influence. Special strategic emails were sent to people like CEOs. This encouraged recipients to share with a wide audience (such as their entire employee network).

This approach helped Harry’s to build anticipation for their launch and generate a sense of exclusivity and urgency among their target audience. By tapping into their networks, they were able to create a snowball effect, with the news spreading rapidly and organically among their audience.

Harry’s prelaunch program was a strategic and effective way to build buzz and generate excitement for their brand. Between the personal invites and the tailored content, referrals were introduced to Harry’s in a conversational and friendly way.

What strategies can you steal?

Make your product seem exclusive. This can create a buzz and people will want to join partly out of curiosity, but also because someone they know (and likely trust) invited them to this ‘exclusive’ thing. 

Harry’s exclusive list and first people to know about the referral program were:

• People the founders talked to, and who were interested in Harry’s story. 
• Friends of the Harry’s employees, invited by the employees they knew personally.

These two groups worked really well as CEOs would have a great influence on their network and employees. And their employee group was able to share with individuals they knew really well (who better to trust than a friend who also works for the company being discussed).

Streamlined design

Harry’s wanted to build a campaign that relied on credible referrals. One way they achieved this was by creating a dedicated page to referrals during their prelaunch. In fact, the prelaunch program was made up of two pages. They included page 1: the sign-up page (splash page), and page 2: the referral page.

The sign-up page only showed a teaser of the product and invited people to sign up to find out more. This was beneficial in that it piqued people’s curiosity (be the first to know) about something new. Another thing they did was prevent distraction. On this page, there were no links out, and no other distracting information. The person could only enter the email or leave completely.

Then, once they signed up and confirmed they were interested, they were directed right to the referral program. This worked well because it was placed after a high interest point. The person was obviously interested as they gave their email. After that confirmation, it’s prime time to offer free products. Not only would the person be one of the first to try it, but they could potentially get the product without having to buy it (just because they sent a referral).

What strategies can you steal?

Harry’s had all avenues end at the referral program. By limiting page options during this launch, they were able to both focus on attracting sign-ups and referrals. You should also keep these pages simple. Harry’s splash page was very simple, and only used 1 strong CTA. 

 

Element of exclusivity

This prelaunch also allowed Harry’s to add an element of exclusivity to their product. Because it was new, and you basically had to be invited to learn about it, it led to people taking action. 

It was also the messaging used that made this an exclusive club. The sign-up page struck a chord with the messaging “be the first to know.” Essentially, this email grants exclusive access to insider information. This helped give them a sense of prestige, as owning or experiencing something that is not available to everyone else can be seen as a symbol of status.

Then once they sign up, the message on the referral page was “don’t leave your friends behind.” This provoked referrals because people love sharing insider access with their peers. Why? It boosts their social currency and makes them the reason someone learns about a good product. In this case, referrers were among the first to receive access to Harry’s product.

This tactic also led to FOMO. As we all know, Fear of Missing Out (FOMO) is a powerful motivator for many consumers. By creating this feeling with a sense of exclusivity, Harry’s was able tap into this fear and motivate consumers to take action before they miss out on a unique opportunity.

What strategies can you steal?

Try to create exclusivity. This worked well for Harry’s for several reasons. It created a sense of  prestige and FOMO. Which led people to sign up and continue referring. 

By creating an exclusive product or service, Harry’s was able to differentiate themselves from their competitors and make their brand stand out. 

Clear, uncluttered landing page

There are serious perks to keeping landing pages simple. A landing page with a clear message and a single call-to-action (CTA) is more likely to convert users than a cluttered page with multiple CTAs. By removing distractions and focusing on the primary goal, a clear and uncluttered landing page can increase conversion rates.

Harry’s made it very clear on what people should do and how they should navigate the page. This really helped lead to higher engagement and a higher conversion rate.

What their landing page did well:

• Headline gets right to the point. Harry’s is coming, Be the first to know, and invite friends & earn product, are simple, but let the user know exactly what the page is all about with just a quick glance.
• It’s followed by an explanation.Harry’s did not choose to be too wordy. Instead, a brief explanation was able to help them get viral signups. 
• They added visual appeal. Strategically chosen imagery draws in the eye and keeps people interested. They used an image of their razor for the initial page, and then added an image of a wooly mammoth on their referral page (great choice to get the referrer to ingrain their logo into their head).

What strategies can you steal?

Like Harry’s, you’ll want to keep landing pages short and concise (which is true for all types of landing pages). It’s even better if you are able to focus on one goal per page. By having the sign up and referral pages separate – they were able to get people to do both. If they would have asked for a referral on the splash page – it likely would not have been as successful.

Easy sharing

If sharing the referral program is too complicated or time-consuming, users are less likely to do it. By providing easy sharing options, such as social media buttons or pre-written emails, users can quickly and easily share the program with their network. This is exactly why Harry’s did it this way.

Harry’s made their referral page easy by:

• Giving multiple sharing options. Multiple sharing button options, all easy to find and access. Harry’s seems to have added even more options as they went along. At one point they offered the referral link, Facebook, and Twitter. Eventually they even added in an email button.

• Displaying a pronounced referral link. The individual referral link is one of the first things someone will see. 
• Providing preset messages. Social media messages were preset so referrers didn’t have to figure out what to say. 

What strategies can you steal?

With any type of referral program you run, easy sharing is key to its success. Harry’s made this easy for users by providing preset messages for social sharing, and made the referral link easy to find for quick sharing. 

The referral landing page in the scenario acts as the referrer dashboard as well. Upon signing up on the splash page, the user is automatically eligible to start referring. So, there is no need for signing up or entering your email again. The user can simply click a button to share, or snag their link and go.

Motivating tiered referral rewards

Harry’s got the reward structure right for a pre-launch program. At the time, no one had tried the product yet. But the buzz around it was real — and Harry’s was smart to use the product itself as the referral reward.

Rewards worked because:

• They were attainable. The first tier was just 5 referrals — easy enough that participation felt worthwhile from the start.
• They scaled. The more referrals sent, the bigger the reward. Tiers at 5, 10, 25, and 50 referrals created natural progression.
• They led to multiple invites. Reaching the next tier motivated people to refer more than one friend.
• The top reward was worth it. A full year of free blades at 50 referrals — over 200 people hit this tier, creating a group of super-advocates.
• Rewards acted as product samples. Free products meant referrers got their first taste of Harry’s at no cost, hooking them before the product was even on sale.

What strategies can you steal?

Sometimes, a reward is the tipping point in getting someone to refer. If the reward isn’t worth it, or if it seems unachievable, no one will participate. Harry’s offered multiple tiers of referral rewards, so even after just a few referrals a reward was given. 

Harry’s also chose to use their product as the reward. This worked really well for them, as it gave people the opportunity to try the product first, and hook them to come back to purchase later on. Plus, with enough referrals, a person can have the whole shaving system to start off. 

Gamified experience through a progress bar

Harry’s referral page included a progress bar showing how close participants were to the next reward. As referrals came in, the bar filled in. The count was also tracked numerically underneath.

These visuals motivated referrers to keep going. “I only need two more to hit the next tier” is a completely different feeling than staring at a flat referral count with no context. The progress bar made the goal feel close — which it often was, especially at the lower tiers.

What strategies can you steal?

Adding elements of gamification to a referral program can make the program even more interesting to users. When users can see these visuals, it can motivate them to keep going. “Oh, I only need ‘x’ more to get to the next tier.”

By adding game-like elements to your referral program, such as points, badges, levels, or leaderboards, you can tap into your happy customers’ intrinsic motivation and make referring more fun and rewarding. People are more likely to engage in an activity that they find enjoyable, and the prospect of earning rewards and recognition can further fuel their motivation. This may be why the Harry’s program chose to use both a progress bar and the number tracker.

Compelling referral message (and why it worked)

The last piece that drove sharing was the pre-written message Harry’s gave referrers. The tweet example — “Can’t wait for @harrys to launch. I’m going to be shaving for free!” — worked because it made friends curious without over-explaining. Shaving for free? How? That’s enough to get someone to click.

But the deeper reason Harry’s messaging worked is in the referral page headline: “don’t leave your friends behind.” That’s not a reward pitch. It’s a prompt to do something generous. Referrers weren’t being asked to recruit — they were being invited to bring their friends along to something good.

This is the dynamic that separates programs people actually share from programs that feel transactional. When the message centers on what the friend gets — the access, the deal, the insider moment — the referrer feels like they’re doing their friend a favor, not monetizing a relationship. That’s the difference between a referral that spreads and one that sits.

By giving users a pre-filled message, Harry’s also kept the barrier to sharing as low as possible. Click, share, done.

What strategies can you steal?

Harry’s made sharing their product easy. By giving users a prefilled message, they kept the referral process as simple as possible. Plus, the referrer wasn’t cashing in on a friendship. They gave their friend access to something good (and new). That shift in framing changed how sharing feels, which changed how much sharing happens.

You can also use a similar message on an email form for the users. By allowing the user to click and share, without having to come up with a message on their own, you can increase your chances of getting a referral.

How to design a program page like the Harry’s referral program

Part of the reason Harry’s program worked so well is because it had a highly converting referral program page. Fortunately, a good referral software that handles tiered programs, like Referral Rock, will be able to help with this key aspect of the program. It will also help you with other goals, like referral tracking, reward management, and reporting.

Harry’s referral page was successful because it…

• Provided eye-catching imagery. This may not seem as important as other aspects of the page. But the truth is, imagery can help keep people on the page longer. A well-designed referral program page should feature clear and engaging visuals that help to communicate your message and make the page more visually appealing. This might include images, infographics, or videos that highlight the benefits of your program. Or at least be able to build that connection between your brand and users (a fun version of your logo – like Harry’s did).
• Use a compelling headline. People need to know what they have to do. The referral program page should feature a clear description of what they should do and it should drive them to your call-to-action.
• Used social currency. Harry’s added an element that showed the intrinsic benefits of sharing “don’t leave your friends behind”. This type of message can make someone feel good for sharing something. 
• Provided explanation. Harry’s provided a simple explanation of how the program works. It’s important to clearly communicate how to share along with the benefits of doing so. This might include rewards or incentives that are available for successful referrals, as well as the benefits that the referred person will receive.
• Provided multiple sharing options. They encouraged visitors to share with their friends and contacts, by making it as easy as possible to do so. They included social media sharing buttons with pre-filled messages that visitors can easily share with their networks.
• Referral links were easy to find. A copyable referral link that referrers can share anywhere was up front and center. They did not make anyone go digging for their link. 
• Utilized gamifying objects. Harry’s provided a motivating progress bar with how many referrals were needed for each reward, plus pictures of the rewards. This helped encourage users to refer multiple times. 
• Provided a prefilled and compelling message. This message is vital because it’s what is sent to friends. When it’s done right, it should make friends want to click and learn more.

What to keep in mind when running your own program

Harry’s set a high bar. Your program probably won’t go viral in the same way — but a well-designed referral program can still bring in a steady stream of new customers. A few things to think through:

Is your product worth it? There needs to be genuine interest before a referral program can gain traction. Harry’s had a compelling value proposition from the start — quality razors at a lower price point. Before launching a program, make sure people actually want what you’re selling. Harry’s talked about what made their upcoming product great and found interested people to seed the program’s first cycle of sharing.

Use referral software to handle the operational work. Software can automate reward fulfillment, run tiered programs, and include safeguards against referral fraud — especially important in a prelaunch that relies on collecting real emails. Referral Rock supports tiered programs and handles the operational complexity so you can focus on the product.

Decide on your reward structure upfront. If referred friends need to make a purchase, consider setting the first reward tier at just one referral — this makes participation feel immediately achievable. Think about how rewards tie into the customer experience: Harry’s used coupons that drove referrers back to the full launched site, which worked well for a prelaunch context.

Don’t treat it like a one-time campaign. This is where Harry’s own story offers a caution. They ran a brilliant pre-launch program, then let it lapse after launch — and by their own admission, likely missed out on trackable referrals during that gap. A referral program isn’t a launch event. It’s an ongoing operation. Referrals happen continuously as you get new customers, so the program needs to keep running alongside the business. Build referral touchpoints into your standard customer experience — confirmation emails, post-service follow-ups, your website — so the program keeps rolling even when no one is actively thinking about it. Harry’s pre-launch showed what’s possible when you make sharing easy. Running it as a permanent operation is what captures that value over time.

Conclusion

Harry’s pre-launch worked because they got two things right that most programs get wrong. First, they made sharing feel generous — the “don’t leave your friends behind” message, the product-as-reward structure, the sense of giving friends early access. When a referral feels like a favor instead of a transaction, people do it more. Second, they designed for momentum: employee-seeded, tiered rewards, a viral loop that spread through existing trust.

The lesson isn’t that you need a viral moment. It’s that the mechanics Harry’s used — low-friction sharing, attainable tiers, messaging centered on the friend’s experience — are replicable in any program. The part Harry’s didn’t get right (treating it as a campaign with an end date) is just as instructive.

Build a program with those mechanics baked in, run it continuously, and you won’t need a pre-launch event to see results.
