Top 8 'Product-as-Billboard' Growth Hacks to implement for Founders to Build a Self-Marketing Product in 2025 - Goh Ling Yong
As a founder, you're constantly fighting a two-front war: building a killer product and figuring out how to get it in front of the right people. The traditional marketing playbook often feels like a leaky bucket. You pour money into ads, content, and social media, but the moment you turn off the tap, the leads dry up. It's an exhausting, expensive hamster wheel.
But what if your product could do the heavy lifting for you? What if every new user, every shared document, and every collaborative session became a tiny, effective billboard for your brand? This is the core idea behind building a "Product-as-Billboard"—a self-marketing product where growth is baked into the very DNA of the user experience. It's a shift from renting attention to earning it, creating a powerful, organic, and sustainable growth engine.
This isn't a mythical concept reserved for Silicon Valley unicorns. It's a strategic framework that any founder can implement. It’s a principle I, Goh Ling Yong, constantly emphasize to the founders I advise: your product should be your number one growth channel. So, as we look towards 2025, let's ditch the leaky bucket and build something that refills itself. Here are the top 8 "Product-as-Billboard" growth hacks to turn your product into your best salesperson.
1. The 'Powered By' Signature Move
This is the quintessential product-led growth tactic, and for good reason: it’s simple, effective, and works across a huge range of products. The "Powered by" badge is a subtle, non-intrusive way for your product to sign its own work. It’s the digital equivalent of an artist’s signature on a painting. When a user interacts with something created by or sent from your product, this little badge tells them exactly what tool made it possible.
Think about the classic examples. Early on, Hotmail appended "Get your free email at Hotmail" to the bottom of every email. Today, you see it with customer support widgets ("We run on Intercom"), survey tools ("Create your own free survey with Typeform"), and email marketing platforms. This strategy works because it places your brand name directly in front of a new, highly relevant audience at a moment of trust. If someone receives a well-designed survey or has a great customer support chat, they're naturally curious about the tool that powered it.
How to implement it:
- Be Subtle, Not Spammy: The badge should be tasteful and unobtrusive. A small, greyed-out logo or line of text works best. The goal is discovery, not a hard sell.
- Link Intelligently: Don't just link the badge to your homepage. Link it to a specific landing page that acknowledges the referral source. For example, a link from a survey tool could go to a page titled, "Create Beautiful, Engaging Surveys Just Like the One You Took." This context increases conversion rates significantly.
- Offer a White-Label Option: For your paying customers, offer the ability to remove the badge. This creates a clear value proposition for upgrading to a paid plan and monetizes the feature itself.
2. Viral Loops Fueled by Self-Interest
A viral loop occurs when a user's natural use of your product exposes it to new potential users. The most powerful viral loops are those driven by mutual self-interest. Dropbox is the textbook case study. Their masterstroke wasn't just asking users to "invite a friend." They offered a compelling, product-related incentive: "Invite a friend and you both get 500MB of free space."
This transformed sharing from an act of altruism into a strategic move to enhance one's own product experience. Users weren't just marketers; they were active participants in their own upgrade path. This creates a powerful, self-perpetuating cycle of customer acquisition. The key is to find an incentive that is deeply tied to the core value of your product—more storage, more collaborators, more design credits, access to a premium feature, etc.
How to implement it:
- Identify Your 'Product Currency': What is the valuable, expandable resource within your product? For Dropbox, it was space. For a project management tool, it might be the number of projects. For a design tool, it could be premium templates.
- Make it a Double-Sided Incentive: Rewarding both the referrer and the new user is crucial. This makes the invitation feel like a gift, not a sales pitch, dramatically increasing the likelihood that the friend will accept.
- Seamless Sharing Flow: Integrate the referral system directly into the user workflow. Prompt users when they're most engaged or when they're about to hit a usage limit. Make sharing as easy as a single click.
3. Shareable Outputs with Subtle Watermarking
If your users create something with your product, that output is a potential billboard. Every time a user shares their creation, they are implicitly endorsing your tool. This is one of the most powerful forms of social proof because it’s not an ad; it’s a demonstration of value. The key is to make your product’s outputs inherently shareable and to brand them subtly.
Canva is a master of this. Millions of social media posts, presentations, and posters are created on their platform daily. Free users' downloads often come with a small, unobtrusive Canva watermark or a suggestion to upgrade for a premium element. Similarly, every TikTok video shared on other platforms carries the TikTok logo and username, acting as a constant, viral advertisement that drives viewers back to the app.
How to implement it:
- Design for Shareability: From day one, think about what users will create and where they will share it. Optimize export formats and dimensions for popular platforms like Instagram, LinkedIn, or Twitter.
- Implement Smart Watermarking: For free tiers, add a tasteful, non-disruptive watermark. It shouldn't ruin the user's creation, but it should be clear enough to attribute the work to your tool. Like the "Powered by" badge, offer its removal as a premium feature.
- Create 'Trophy' Outputs: Think about what users would be proud to share. This could be a certificate of completion, a beautiful data visualization, or a performance report. Make these outputs look professional and polished, so users want to show them off.
4. Public Profiles, Leaderboards, and Feeds
Humans are social creatures, driven by status, competition, and community. You can tap into these innate desires by making user activity public (with their permission, of course). This creates multiple billboards at once: it showcases your most active users, creates social proof for newcomers, and generates a network effect where the value of the product increases as more people use it publicly.
GitHub is a perfect example. A developer’s public profile, with its contribution graph, is their modern-day resume. It incentivizes them to use the platform consistently to showcase their skills. Strava does the same for athletes with public activity feeds and segment leaderboards, fostering friendly competition. Duolingo's weekly leaderboards create a powerful retention and engagement loop, encouraging users to come back daily to maintain their streak and ranking.
How to implement it:
- Give Users a Public 'Home': Create a public profile page that users can customize and share. This becomes their hub within your ecosystem and a link they can proudly share elsewhere.
- Introduce Gamification: Leaderboards, badges, and streaks can turn mundane tasks into a fun competition, encouraging deeper engagement and giving users a reason to share their progress.
- Focus on Positive Social Pressure: The goal is to encourage and motivate, not to shame. Frame leaderboards around positive metrics like "most helpful," "most creative," or "longest streak" to foster a healthy community.
5. Embeddable Widgets and Content
Why keep your product confined to your own website? An embeddable widget allows your users to take a piece of your product's functionality and plant it directly on their own digital real estate—their website, blog, or Notion page. Every single embed acts as an interactive billboard, driving awareness and acquiring users from thousands of different sources.
Calendly has built a massive business on this principle. You can embed your scheduling link directly on your website, allowing visitors to book a meeting without ever leaving the page. YouTube is another giant built on embeds; every news site, blog, or forum that embeds a YouTube video is essentially running a free ad for the platform. This strategy works because it provides immense value to the user (convenience, functionality) while simultaneously serving your growth objectives.
How to implement it:
- Identify Your 'Embeddable Unit': What is the most useful, self-contained piece of your product? It could be a booking form (Calendly), a video player (YouTube, Loom), a survey (Typeform), a data dashboard, or a chat widget (Intercom).
- Make Embedding Effortless: Provide a simple "copy and paste" embed code. The process should be foolproof for even the least technical user.
- Brand the Widget: The embedded widget should clearly (but subtly) feature your branding. When a visitor interacts with it, they should know what tool is powering the experience. Include a clickable logo that leads back to your site.
6. Collaboration Features That Invite Non-Users
The fastest way to acquire a new user is to have a current user invite them. The most natural way to make this happen is through collaboration. When your product is designed for teams, inviting new people isn't a marketing task; it's a core part of the workflow. Tools like Figma, Miro, Google Docs, and Notion have perfected this.
The magic happens when a user needs to get feedback, co-edit a document, or brainstorm on a whiteboard with someone outside their team or company. They send an invite link, and the recipient is pulled into the product. The key here is the "guest" experience. It must be incredibly smooth, low-friction, and immediately demonstrate the product's value. If the non-user has a great experience, they'll remember the tool the next time they have a similar need.
How to implement it:
- Frictionless Guest Access: Do not force guests to create a full account immediately. Allow them to view or comment with just a name or email. The goal is to get them to the "aha!" moment as quickly as possible.
- Showcase Value Instantly: The guest's landing experience should be flawless. They should immediately understand the context of what they've been invited to and how to interact with it.
- Provide a Gentle Nudge to Sign Up: After the collaborative session is over, you can gently prompt the guest to create their own free account to save the work or start their own project. For example, "Enjoyed collaborating? Get your own free account to create unlimited boards."
7. Data-Driven, Shareable 'Wrapped' Reports
People love data about themselves. They're fascinated by their own habits, productivity, and progress. If you can collect this user data and package it into a beautiful, insightful, and highly shareable report, users will become your most enthusiastic marketers. This is the genius behind Spotify Wrapped.
At the end of each year, Spotify gives users a personalized summary of their listening habits. It’s not just a list of songs; it’s a story told with slick graphics, fun labels ("You listened to 5,000 minutes of Synth-Pop"), and ready-made social media templates. Users share it because it says something about their identity. This same principle can be applied to almost any product. Grammarly does it with its weekly writing reports, and health apps do it with milestone achievements.
How to implement it:
- Identify Share-Worthy Metrics: What data are you collecting that would make a user feel proud, productive, or unique? Think "books read," "tasks completed," "code pushed," or "money saved."
- Invest in Design: This is not the place for a boring spreadsheet. The report must be visually stunning and designed for social media formats (like Instagram Stories or LinkedIn posts). Make it an experience, not just a data dump.
- Make Sharing a One-Click Affair: Add prominent "Share to Twitter" or "Share to Instagram" buttons directly within the report. Pre-populate the post with a compelling caption and relevant hashtags to lower the barrier to sharing even further.
8. Ecosystem Plays: Integrations and Marketplaces
This is a more advanced strategy, but it can create an incredibly powerful and defensible growth channel. By integrating your product with other tools that your customers already use, you get your brand listed in their app marketplaces. Each of these listings is a high-intent billboard. A user browsing the Slack App Directory or the HubSpot App Marketplace is actively looking for a solution to a problem.
When they see your product listed as a trusted integration partner, it comes with a powerful dose of social proof. It tells them your product is legitimate, secure, and will work seamlessly with their existing stack. Zapier, for instance, has built its entire business on being the connective tissue between thousands of apps, and in doing so, it gets its brand in front of millions of users inside those other apps.
How to implement it:
- Start with Your 'Core Stack': Survey your customers to find out what tools they use every single day alongside yours (e.g., Slack, Google Workspace, Salesforce, HubSpot). Prioritize building integrations with these.
- Build a High-Quality Marketplace Listing: Don't just submit your name. Invest time in creating a compelling listing with clear copy, good screenshots, and even a short video demo. Your marketplace page is a landing page.
- Promote the Integration: Don't just build it and hope they come. Announce the integration to your own users, co-market with your new partner through blog posts or webinars, and leverage their audience to drive new sign-ups.
Your Product is Your Best Marketer
Building a self-marketing product isn't about finding a single silver bullet. It's about a fundamental shift in mindset. It's about viewing every feature, every user flow, and every touchpoint as an opportunity for organic growth. It’s about building a product so valuable and inherently shareable that your users become your willing, enthusiastic evangelists.
By thoughtfully implementing these "Product-as-Billboard" strategies, you can move away from the expensive, short-term tactics of traditional marketing and build a sustainable, compounding growth engine. You'll lower your customer acquisition costs, increase user retention, and build a brand that grows stronger with every single person who uses it.
