about me
Quick Bio: Mario Peshev
I lead DevriX, an execution unit operating alongside leadership teams to implement and stabilize operating systems across revenue, operations, and data. I also founded Growth Shuttle, a market intelligence and advisory firm focused on execution, systems, and operating leverage in the mid-market.
In parallel, I engage selectively and fractionally as a Technical Value Creation Advisor, supporting sponsors and portfolio leadership teams with post-acquisition execution, systemization, and operating resilience.
This work is focused on durability under scale: reducing operational risk, improving throughput, and ensuring value creation initiatives hold beyond the first phase of integration.
I have previously trained courses and workshops for organizations like VMware, SAP, Software AG, CERN, Saudi Aramco, with 10,000+ hours of professional consulting over the past 20 years. Today, DevriX scales through its RevOps efforts, data clarity, GTM enablement, strategic consulting, operational efficiency, AI augmentation, compliance, and more.

“Responsive and Effective”
We hired Mario on an emergency training/consulting job for 3 weeks and he was simply superb! He was polite, punctual, responsive, and very effective in a Job with Aramco Oil. I will hire him again and will expect nothing less than the best.

“WordPress Magician”
Mario is a WordPress magician. From day one his impact on our business was immediate.
We run a media platform with intense daily deadlines and 80+ clients to service, and we desperately needed his skill and service to continue to grow. I love Mario–because he has saved and made our company money. He’s professional, fast and I sleep well at night knowing he (via DevriX) is at the controls.

“Exceedingly trustworthy”
I’ve been working with web design firms since the mid-90s. Mario’s firm DevriX is the best I have worked with by a wide margin. Their ability to customize high-performance WordPress sites is exceptional. They bring a spirit of collaboration to their work, as well as taking initiative on virtual project management.

THE ENTREPRENEURSHIP FAD AND THE DARK SIDE OF GOING SOLO
126 Steps to Becoming a Successful Entrepreneur
The US Census Bureau reported 32,570,855 small businesses operating across the States.
Allegedly, every tenth American runs their own business.
However, a follow-up story discloses that 76.2% of businesses that had no employees accounted for merely 4% of SMB sales.
“126 Steps to Becoming a Successful Entrepreneur” paints a different portrait of the startup ecosystem and the reality of “being your own boss”.
What I appreciate about this book is how real it is. It’s actually the blueprint on what to expect in order to stay focused for the true entrepreneurs who will be dedicated to their venture, day in and day out; and 80-100 hour work week in and work week out. As a career-long entrepreneur myself, I found myself shaking my head in agreement with much of the advice and experience shared by the author.
