Lemon Digital HQ just added a major brain to its brand muscle.

The influencer marketing and brand development agency announced the launch of Lemon IQ, a Gen Z-focused research and strategy arm designed to help brands avoid the all-too-common fate of tone-deaf campaigns. Think of it as a direct pipeline into the cultural operating system of the most elusive and economically powerful generation: Gen Z, with over $450 billion in global spending power.

Culture Meets Commerce

“We built Lemon IQ to bridge the gap between smart brand strategy and actual Gen Z insight,” said Sarah Reilly Engel, co-founder of Lemon Digital HQ. “Modern brand growth lives at the intersection of culture and commerce—and Gen Z defines both.”

Engel, along with co-founder Jennifer Powell, brings serious pedigree from the creator economy, with backgrounds spanning LTK, Next Models, and work for brands like Armani, Blue Lagoon, and Brilliant Earth. With Lemon Digital HQ, they’ve consistently delivered influencer activations and brand experiences that resonate. Now, with Lemon IQ, they’re adding something most influencer agencies lack: a feedback loop backed by data, research, and Gen Z's own voices.

Real Voices, Real Feedback

The core of Lemon IQ’s methodology is simple but potent: start with Gen Z, not just personas. The team convenes student influencers aged 16–28 for structured focus groups, supplements those sessions with surveys, and delivers reports brands can act on—before they commit major budgets to production or ad spend.

But IQ doesn’t stop at insight. Those same student participants often become campus ambassadors, turning firsthand feedback into real-time promotion. The result is a feedback-to-flywheel model that’s part research lab, part activation engine.

“Too many brands are flying blind,” said Powell. “We’ve seen launches flop because they were built on stale assumptions. With Lemon IQ, you get breathing, evolving feedback.”

Timing Is Everything

This launch isn’t happening in a vacuum. The runaway success of Rhode, recently acquired by e.l.f. Cosmetics for $1 billion, is a case study in combining top-tier storytelling with grassroots Gen Z engagement. Rhode’s playbook—using creators for halo storytelling and campus ambassadors for community buy-in—is exactly the flywheel Lemon IQ is optimizing.

Not Just for Startups

While Gen Z-first DTC brands are obvious customers, Lemon IQ is already being tapped by established retail and CPG players looking to validate product-market fit, de-risk campaigns, and rewrite tired brand narratives.

For example, a legacy beauty brand might use IQ to:

• Pressure test new packaging or shade ranges

• Test campaign messaging with 18-year-old freshmen and 28-year-old early career professionals

• Identify overlooked creators shaping beauty culture on TikTok and YouTube

• Launch a paid ambassador program fueled by peer-to-peer recommendations

Why It Matters

Gen Z isn’t just another demo—they’re a culture engine, often reshaping platforms, language, and product expectations in real time. And they can sniff out inauthenticity in seconds.

By combining bottom-up feedback with top-down brand strategy, Lemon IQ offers something refreshingly rare: a chance to co-create with the audience that decides what sticks.

“We’re not just measuring sentiment,” said Engel. “We’re helping brands build with Gen Z, not just for them.”
