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.

“MBA Disrupted” reflects earlier work on business systems, decision-making, and execution discipline.
Today, my focus is on applying these principles directly inside PE-backed and scaled operating environments

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.
