Fractional Technical Value Creation Advisor ($30M – $500M)
Helping PE-backed mid-market companies eliminate execution delays and stabilize value creation through durable operating systems.
Portfolio-level, fractional engagement with implementation + operation via DevriX.
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. Across retained engagements, DevriX drives value creation for PE-backed and scaled operating companies: revenue operations,
data, go-to-market, AI, and the technology that has to hold under
scale.

“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.

“He saved and made us money”
From day one his impact on our business was immediate.
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 needed his systems and execution to keep growing. He has saved and made our company money. He’s professional, fast, and I sleep well at night knowing his team (via DevriX) is at the controls.

“Candid feedback I find invaluable”
I’ve been working with web design firms since the mid-90s. Mario and his team really took the time to understand our business model. Some of my best interactions with Mario have nothing to do with pending projects, but with the big-picture strategy we need to be thinking about. His candid feedback is invaluable. A real pro to work with.

MBA Disrupted
MBA Disrupted distills two decades of building and operating companies into the systems and decision frameworks behind durable execution. Those same principles now run inside PE-backed and scaled operating environments.
My favorite part of the book is about processes. It is evident that Mario has built and grown multiple businesses.

WHY MOST VENTURES NEVER SCALE
126 Steps to Becoming a Successful Entrepreneur
Most businesses never build anything that scales. The vast majority have no employees and capture only a small share of total revenue.
126 Steps provides a look at why and at what separates the companies that reach durable scale from the ones that stall. It reflects the same evidence-based judgment I now bring to PE-backed operating environments.
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.
