Beyond the Viral Hype: Startup Founders at TechCrunch Disrupt Share the Real Truth About Customer Acquisition

Securing initial customers remains one of the most grueling and high-stakes challenges in the entire lifecycle of a business. Even when young companies manage to generate early buzz, capture initial interest, or secure their first wave of users, there is never a guarantee that those customers will stick around for the long haul. Building lasting retention requires a deliberate strategy that goes far beyond a temporary spike in visibility.

At TechCrunch Disrupt, startup veterans and investors tackled this perennial hurdle head-on. Elia Wallen, the founder and CEO of travel startup Engine; Grant Lee, the founder and CEO of AI-powered presentation software Gamma; and Crystal Huang, a general partner at Google Ventures, took the stage to share hard-earned lessons on how early-stage companies can effectively attract and retain customers in a shifting market.

In the current business landscape, where young artificial intelligence companies like Cluely and Instinct are building massive audiences not just through their software products but also through their founders’ colorful and visible online presences, social media can easily seem like a magic bullet. For founders looking to scale quickly, leaning into modern digital marketing appears to be the ultimate shortcut to reaching early adopters. However, according to Grant Lee, entrepreneurs who want to elevate their business strategy with contemporary marketing tactics must approach them with extreme care and strategic discipline rather than treating them as a simple checklist item.

Gamma managed to scale its business exponentially through an innovative social media strategy that deployed micro-influencers via its dedicated Ambassadors, or "Gambassador," program. The company adopted this ambitious plan well before influencer-based marketing became a tried-and-true playbook for smaller B2B and enterprise tech companies, ultimately propelling the firm to a multi-billion-dollar valuation and substantial annual recurring revenue.

Yet, Lee cautioned that simply handing influencers a platform and telling them to promote a brand online does not automatically translate to genuine sales conversions or sustainable growth. There is significantly more nuance required to make creator-led marketing genuinely effective.

"If you have a product that can serve many different segments or use cases, then you want to basically have creators that can target each one of those," Lee explained during the panel discussion. He noted that the target audience for a flexible software tool varies wildly depending on the professional context. "If you have folks that are in consulting versus people that do all their marketing and create all the decks for their chief marketing officer, there’s all these different segments you might want to go after."

Lee observed that startup founders frequently fall into the trap of treating creator and influencer marketing as a "set-it-and-forget-it" mechanism, expecting the campaign to run smoothly on autopilot once initial agreements are signed.

"I think you’re better served by really spending a lot of time with these creators, because if they’re not able to understand how to articulate the value of your product, it doesn’t matter how much money you spend, it’s just going to fall flat," Lee added, emphasizing that deep collaboration and product education are essential prerequisites for successful digital campaigns.

At the same time, the true effectiveness of social media marketing depends heavily on the specific nature and operational model of the business. Other, more traditional ways of reaching prospective customers can be just as effective—if not considerably more so—depending on the industry.

Elia Wallen understands this dynamic better than most. His company, Engine, which specializes in managing lodging and travel bookings specifically tailored for midsize businesses, successfully bootstrapped its way to $150 million in bookings before ever taking on outside venture capital funding. Notably, they achieved this remarkable milestone with virtually no visible social media strategy to speak of. For Wallen, time-tested traditional sales tactics can prove far more useful and reliable for a growing enterprise than a viral video trending on TikTok.

"We did events and we smiled and dialed," Wallen said, describing the gritty early days of customer acquisition at Engine. "We still have a lot of people picking up the phone. A lot of people who didn’t grow up with that or don’t understand it think that it’s outdated or it doesn’t work, but it does. It’s a hard thing. There are a lot of companies that just refuse to do it or don’t know how to do it well. But they’re missing out on a very big offline client base." He underscored his point bluntly: "The phone still works."

Wallen also highlighted a uniquely creative in-person tactic that his company deployed during its scrappy early days to stand out from the crowd at industry gatherings. In a bid to draw attention on crowded convention floors, Engine hired a professional magician named David to perform close-up magic tricks for prospective clients at events, skillfully encouraging them to visit the company’s booth and engage with the team. For Wallen, stories like this illustrate that old-fashioned personal engagement and creative offline experiences can work just as well, if not better, than the latest digital and social media growth hacks.

Once a startup manages to secure its initial wave of customers, however, the challenge immediately shifts from acquisition to retention and value maximization. Crystal Huang, who has managed scores of early-stage startups and shepherded them toward long-term success from the vantage point of Google Ventures, pointed out that a tremendous amount of strategic value can be unlocked simply by closely analyzing how existing users actually interact with the product.

"Can you look into usage data and figure out if it’s recurring, if it’s increasing, if they are referring their friends?" Huang asked the audience. She stressed that the earliest indicators of product-market fit and long-term viability often manifest clearly in early usage and retention metrics long before broad market saturation occurs.

Furthermore, Huang noted that successful companies must look beyond standard analytics to identify the most passionate users within their ecosystem. Founders need to actively spot the individuals who derive outsized value from the platform and are genuinely eager to deepen their relationship with the brand.

"And then also, do you see some super fans, right, who even want to work at the company, promote the company, be attached to the brand?" Huang asked. "You need to have ways to create evangelists who are really passionate about the product."
