Our Role for Agencies & Brands
We saw a consistent problem in the marketplace: agencies charging premium retainers and brands investing heavily in ads, yet listings were still underperforming. Not because the product lacked potential, but because the page wasn’t engineered to convert.
Engin8.io provides the scalable back-office execution that agencies need and the performance-first creative infrastructure that brands want—without the need for internal expansion.
Our focus is narrow but deep: A+ content architecture, structured split testing, and mobile-first storefronts that actually move the needle on your P&L.
What We Care About

Measurable performance lifts

White-label operational excellence

Psychology-driven design

Mobile-first optimization

Rapid execution & scalability
What We Care About
Built on Proven Infrastructure
Engin8 was built by founders with 15+ years operating at the highest level of ecommerce not as consultants, but as builders. Lee Loree and Robert Ferreira co-founded Seller Investigators and grew it into a global operation with a 300+ person team abroad before the business was acquired by Carbon6.
That same team, the same facility, and the same proven operating systems are the engine behind Engin8 today. When you work with us, you’re backed by infrastructure that’s already been tested, scaled, and validated at an enterprise level.
What We Believe
Four principles that guide how we think, build, and operate for our partners.

Make decisions
with clarity.

Execute with
precision.

Move with
intention.

Build systems that scale.
Inside the Engin8 Operations Floor
Our performance isn’t magic—it’s engineering. We operate with a dedicated analyst floor where every brand is managed by specialized pods focused on rigorous split testing and daily optimizations.
From high-intensity strategy huddles to deep-dive data architecture, our operations are built to maintain the continuous motion that the “8” in our name represents.
