Navigating Growth at Perplexity AI: Lessons from the Frontlines
How Perplexity's Head of Growth Balances Retention, Experimentation, and Big Swings to Scale in the Competitive AI Landscape
Growth is a word that resonates differently across industries, roles, and ambitions. For tech insiders, it's a matrix of data, product decisions, and marketing finesse. For others, it’s a puzzle with elusive edges—especially in an era dominated by AI tools like Perplexity. Recently, I delved into a candid and enlightening conversation with Perplexity's Head of Growth, where he unpacked the nuts and bolts of scaling a tech product in one of the most competitive landscapes today.
What emerged wasn’t just a story of product metrics and campaigns but a blueprint for navigating complexity, making tough calls, and understanding the human side of the growth equation. Here’s the distilled wisdom.
From Alabama to San Francisco: A Growth Leader’s Unlikely Path
The path to success is rarely linear, and Ramen's story is a testament to this. Born and raised in Alabama, he didn’t follow the archetypal path of someone destined for Silicon Valley stardom. Yet, with a strong family ethos pushing him to seek opportunities beyond his hometown, Ramen found himself at the helm of growth at Perplexity—a platform bridging the gap between search engines and knowledge tools.
His journey traversed an MBA program, founding a startup, and eventually joining Perplexity after the rollercoaster ride of startup life. Each chapter brought hard-won lessons, including the shift from being a founder to a team player laser-focused on growth. As Ramen noted, “Going from steering the ship to being a cog in the machine requires humility, focus, and an ability to adjust your framing.”
Growth: A Discipline with Two Faces
If growth had a definition, Ramen would argue it’s this: an independent function bridging product and marketing. It’s a dynamic role that blends engineering, data science, design, and communication to optimize the user funnel—from acquisition to retention and monetization.
1. Growth Product
Growth on the product side involves engineering user experiences to improve key metrics like activation and retention. Teams obsess over the journey that transforms new users into retained, power users. For Ramen, activation isn’t just about clicks—it’s about ensuring users derive meaningful value early in their journey.
2. Growth Marketing
Growth marketing complements this with tools like lifecycle communication, community building, and campaigns. As Ramen succinctly puts it, “The marketing team’s job is to amplify the product team’s efforts, ensuring the funnel flows seamlessly.”
In practice, these two branches aren’t siloed. The best results emerge when product and marketing teams collaborate closely—iterating on onboarding flows, messaging, and campaigns.
The Golden Question: When to Build a Growth Team?
One of the hardest decisions for early-stage startups is deciding when to formalize growth as a distinct function. Ramen’s advice is pragmatic: post-product-market fit. But he acknowledges that product-market fit is nebulous. Instead, he looks for clear retention signals.
“If you’re seeing 30% retention at month three or four, you’ve got the kindling for a fire. That’s when it makes sense to pour gasoline on it.” The investment doesn’t have to be heavy-handed—incremental improvements in onboarding or user retention can drive substantial returns.
The Retention vs. Acquisition Conundrum
Many startups equate growth with acquisition, but Ramen challenges this instinct. When he joined Perplexity, the team was already seeing robust organic acquisition fueled by curiosity about AI. Instead of doubling down on acquisition channels, he focused on retention.
“Retention is the foundation. If you can move week-one or week-two retention, you’re lifting the entire water level of your user base,” he explains. Perplexity’s activation milestone, for example, hinges on getting users to complete at least three queries in their first session—a metric correlated with higher long-term retention.
But Ramen is quick to warn about gaming metrics. “You can’t fool yourself. If your activation milestone doesn’t translate into deeper engagement or retention, it’s just a vanity number.”
Micro-Optimizations vs. Big Swings
Growth is often painted as a game of micro-optimizations. But Ramen believes this view is incomplete. Micro-optimizations, like improving retention from 30% to 35%, can significantly impact active user counts. Yet they also have diminishing returns. That’s why Perplexity balances these efforts with quarterly big swings, such as launching new features or high-risk marketing campaigns.
“Once a quarter, we take a big swing. It has to be high-risk, high-reward. If you’re not willing to fail occasionally, you’re not aiming high enough.”
The Art of A/B Testing
For Ramen, A/B testing isn’t just a tool—it’s a philosophy. A well-designed A/B test offers clarity about what moves the needle and helps set future priorities. But it’s not without pitfalls. Poorly scoped tests waste time, and results can mislead if not contextualized properly.
His golden rule: go into every test with a hypothesis. “If you don’t have a strong intuition about what will happen, you’re flying blind.”
Acquisition Channels: What Works, What Doesn’t
While Perplexity has primarily grown through organic channels, Ramen has experimented with paid acquisition. His findings reflect broader trends in tech:
Paid Acquisition: A Double-Edged Sword “Paid acquisition is a drug,” Ramen warns. It boosts top-of-funnel metrics but often underdelivers on retention. He cites his experience at Lyft, where turning off paid channels barely impacted organic growth but weeded out low-quality users.
Community-Led Growth One underappreciated channel, according to Ramen, is community. Perplexity has seen success activating power users—students, for instance—to evangelize the product within their networks.
TikTok: A Tough Nut to Crack Testing TikTok ads for young audiences has provided valuable insights, though Ramen acknowledges it’s a “crazy beast” with unpredictable dynamics.
Lessons from Partnerships
Perplexity has leaned heavily on partnerships to drive distribution. Offering free trials through platforms like LinkedIn or bundling Perplexity with existing tools has proven effective. The secret, Ramen says, is to make it easier for someone else to promote your product.
“Let others scream about your value. It’s far more credible than shouting from the mountaintop yourself.”
Building a Team for Growth
Growth leaders often struggle with hiring, but Ramen has a clear ethos: prioritize team fit and entrepreneurial spirit over technical perfection. His ideal candidate is someone who can diagnose problems independently and thrive in ambiguity.
“Great hires don’t need an onboarding doc. They write their own,” he quips.
When asked about hiring Founders, he’s unequivocal: “Founders are comfortable taking big swings and failing. That’s invaluable in a growth role.”
What’s Next for Perplexity?
Perplexity stands out for its ability to answer nuanced, complex queries with sources—an advantage over more generic AI tools. The team’s focus now is on expanding the product’s use cases while maintaining its organic magic. From targeting students to exploring brand marketing experiments, they’re constantly refining their playbook.
One tantalizing possibility? A “Perplexity Wrapped” feature that surfaces users’ most-searched topics or favorite queries—a clever way to merge utility with virality.
Closing Thoughts
Growth is not about shortcuts or silver bullets. It’s about understanding users, obsessing over data, and balancing the art of experimentation with the science of iteration. At Perplexity, growth isn’t just a job—it’s a shared philosophy across teams. And for those navigating the dynamic AI space, Ramen’s lessons offer a compass: focus on retention, embrace big swings, and never stop asking the hard questions.
