    “The Reaction Lab team produced high-quality creator content that we’ve been able to use across our app and social channels. Their UGC assets gave us fresh, high-impact creative, while the micro-influencer campaign drove targeted awareness to our users and boosted app installs. They turned everything around with speed and precision, and have become a genuine growth partner.”

"I’m Hasan, founder of Reaction Lab. For 8+ years I’ve been helping apps and brands grow with creators, PR, and content. I’ve worked with FaceApp, Impro App, AG1, and other leading companies to drive installs, media coverage, and scalable growth engines.


Reaction Lab exists to solve a simple problem: most apps don’t fail because of product — they fail because they never build a repeatable system for growth. That’s what we help you do, with a mix of strategy, operators, and a creator network of 5,000+ at your side."

Why Great Apps
Still Struggle to Grow

Even with a strong product, installs stall without credibility, consistent content, and measurable growth engines.

The Reality

Random influencer tests → no scale.

Inconsistent content → stalls momentum

No credibility → investors/users don’t trust

The Bottlenecks

No PR credibility → users + investors hesitate

Random influencer tests → no compounding

Installs tracked poorly → CAC/LTV unclear

The Solution

Build credibility engines (PR, creators, press)

Scale installs through proven creator systems

Real-time dashboards: Installs, CAC, LTV
