Technical value creation advisor · $30M to $500M

Technical value creation for PE‑backed and mid‑market companies

I work with sponsors, operating partners and leadership teams on technical due diligence, the first 100 days after close, and the revenue systems a value creation plan depends on. I have founded six companies, sold two, and bought more than forty businesses as an operator.

Advisory

Three ways to work together

For sponsors and the leadership teams of their portfolio companies. Engineering, data and RevOps work is done by DevriX, the 40-person company I run.

02

Fractional operating partner

The operating partner role for one portfolio company, on a monthly retainer. I work with management on the 100-day plan and the systems behind revenue and margin, and report to the sponsor.

03

Technology board advisor

A board seat for technology and product decisions. I review architecture, vendors, security and AI spend as someone who has made those calls in companies I founded and ran.
