The sting of a potential investor hanging up mid-Zoom call after declaring your idea “the worst I’ve ever heard” can be paralyzing, but for Gamma co-founder Grant Lee, it became a catalytic moment. Instead of crumbling, he distilled the harsh critique into a core truth: competing against giants like PowerPoint meant growth had to be embedded in the product DNA from day one. This philosophy propelled Gamma from a pre-AI concept to an AI-powered storytelling platform with nearly 100 million users, built on the radical principle that it’s “better to be different than better.” The company deliberately broke the 40-year-old “16×9 prison” of slides by creating flexible, web-native documents that are interactive, multimedia-rich, and mobile-responsive, focusing on the universal pain point that people spend 90% of their time formatting and only 10% on actual content.

Gamma’s explosive growth to 100 million users was not bought through marketing but engineered through a maniacal focus on organic word-of-mouth virality. After an initial launch yielded only 60,000 signups in eight months, the team dedicated itself to perfecting the first 30 seconds of the user experience. This focus on the “aha moment” paid off spectacularly, skyrocketing signups to 50,000 per day following their AI launch without any paid advertising. This foundational virality created a powerful flywheel, allowing them to build “bottoms-up love” among prosumers before strategically sequencing their move into the enterprise market. This patient sequencing meant that when they later introduced Teams and API products, internal champions within companies were already advocating for them.

Company culture and deliberate hiring were just as strategic as product decisions. Grant emphasizes the principle of “hiring painfully slowly,” a discipline that ensured every early hire replicated the founding team’s DNA. Their first seven employees constituted a full “MVP crew” capable of building, marketing, and selling the product end-to-end. This included making design a core competency from the start, with product designers making up a quarter of the early team. For Grant, taste isn’t just visual aesthetics; it’s the entire end-to-end experience, akin to a restaurant where every touchpoint—from being greeted to paying the check—must feel crafted and magical. This holistic view of design and a founder-led approach to everything, from personally onboarding influencers to starring in launch videos, cemented a brand that feels human, trustworthy, and inherently different.

Surprising Insights

• The pivotal growth catalyst wasn’t a feature but perfecting the first 30 seconds of user experience, which increased daily signups from a trickle to tens of thousands overnight.
• A quarter of the early team were product designers, a highly unusual allocation for a startup, underscoring the belief that inventing new AI user experiences is fundamentally a design problem.
• The company achieved profitability within three months of launching its pricing model, largely by anchoring it to the familiar cost of ChatGPT to reduce user friction, rather than complex optimization.
• Founder Grant Lee personally onboarded every single influencer in the early days, viewing them as an extension of the sales team, which he did himself before ever hiring for marketing.
• “Taste” is defined not as visual design alone, but as the entire restaurant-like experience—from entering the product to sharing the final output—all of which must feel crafted and delightful.

Practical Takeaways

• Prioritize word-of-mouth virality above all else before investing in marketing; if users aren’t organically telling others about your product, you haven’t reached true product-market fit.
• Sequence your market entry: For horizontal tools, build deep prosumer love and a bottoms-up movement before attempting a top-down enterprise sales motion. This creates internal champions that make enterprise adoption significantly easier.
• Hire painfully slowly and do the job yourself first. Founders should experience the core functions (like marketing, sales, support) to understand the pain points and nuances before hiring, ensuring they can recognize true excellence in candidates.
• Make it dead simple to create and dead simple to share. This two-part mantra completes the organic growth flywheel, ensuring every user can easily become a promoter.
• Treat brand and culture as two sides of the same coin. Founders must be the chief stewards of the brand; if you don’t care deeply about it and embody it externally, no one else will.
