About Nelly Perez
Helping Entrepreneurs Scale with Precision, Performance, and Peace of Mind
Humble Beginnings
Nelly Perez was born in the Dominican Republic and moved to the U.S. at age eight, chasing a better life his parents could only imagine.
They arrived with no money, no English, and no safety net, just faith and a relentless work ethic.
Nelly watched his father work relentlessly, and from him, he learned the values that would shape everything:
Show up early. Outwork everyone. Never cut corners. And always do what’s right, even when no one’s watching.
The Entrepreneurial Start
Nelly Perez began his entrepreneurial journey in 2019 by launching Nelly IS Marketing, a data-driven agency rooted in business psychology, buyer behavior, and performance strategy.
What began as a solo venture quickly became a fast-growing agency. Client results spoke for themselves, and as demand grew, so did the team.
Over time, Nelly and his team worked with hundreds of companies, managing advertising budgets ranging from $50 to over $20,000 per day, and generating more than $100 million in revenue across multiple industries.
Hitting the Breaking Point
By the time the agency reached its 15th team member, internal cracks were no longer tolerable.
Client outcomes remained strong. But internally, it felt like a fire drill every day.
The team had talent, but no structure.
Tasks slipped.
Communication was scattered.
Leaders were improvising instead of leading, and Nelly became the bottleneck, spending 14+ hours a day plugging holes and answering questions just to keep everything afloat.
Rebuilding From the Inside Out
Nelly knew this wasn’t sustainable. Not for his business, and not for his life.
Instead of layering more tools or throwing more people at the chaos, he stepped back to rebuild from the ground up.
He went deep into execution frameworks, leadership systems, and operational design.
Dozens of books. Multiple coaches. Countless tools that promised clarity but delivered more confusion.
Nothing worked end-to-end. So he built what was missing.
He rebuilt his company with:
- Role-specific scorecards
- Real-time dashboards and daily performance tracking
- Automated quality control and SOP enforcement
- Systems that created accountability without micromanagement
- A performance-driven culture built on data, not pressure
The result:
A 40-person agency that runs like a machine, with or without his daily involvement.
Proving the System Again
To prove the system could scale beyond one company, Nelly acquired a home improvement business from a former client.
He implemented the same operating infrastructure, scaled it, got it down to one hour of his time per week, and successfully exited.
That confirmed it: this operating system worked across industries.
And it became the foundation for something much bigger.
The Birth of EIDN
That framework evolved into EIDN: the first operating system built to help growing companies run with the clarity, precision, and performance of the world’s best.
EIDN gives founders the tools to:
- Track execution in real time
- Score team performance like a professional sports team
- Automate accountability and process adherence
- Build a culture that improves through data, not pressure
Helping Founders Escape Chaos and Scale with Confidence
Nelly now helps founders across industries install the same operational infrastructure that scaled his own companies.
Through EIDN, Nelly IS Marketing, his book Fight Smart, and his work as a Speaker, Nelly equips growth-minded leaders to scale without chaos.
Having worked with hundreds of companies ranging from early-stage teams to 9-figure organizations, Nelly’s had a front-row seat to what separates companies that stall from those that scale.
If your company still relies on your constant oversight, scattered tools, or gut instinct to make decisions, it’s fragile.
Through his companies and experience, Nelly helps you bring the execution systems behind the world’s top operators into your business, so you can scale with structure, clarity, and control.
