Karl has built companies and finance functions across construction, AEC, broadband, multi-state infrastructure, services, and technology. His work spans accounting and close integrity, FP&A, liquidity, treasury, working capital, job cost and WIP, lender and investor communication, capital planning, finance transformation, and executive decision support.
His method begins with the economics. Benchmark performance, isolate the anomaly, and trace it through the operating model, incentives, systems, and decisions behind the numbers. The objective is not more reporting; it is a more reliable basis for action.
Karl’s record includes part-ownership of a Portland/Seattle enterprise generating $100M+ in annual revenue, opening and building its Seattle market, later acquiring his partners’ interests, scaling the operation to $30M+ in annual revenue, leading teams of 200+, raising growth capital, evaluating private-equity acquisitions, and building and scaling businesses from $0 that collectively generated more than $200M in cumulative revenue. He also built and led the finance departments and operating systems required to support that scale. At Broadband Development Group, he led finance-function and operating-discipline work in a growth-oriented construction and broadband environment. He now brings that operator context to KSIG engagements. CFO leadership remains the foundation; fractional COO mandates focus on accountability, operating cadence, workflows, implementation and reducing founder dependency in construction, home-services and other project-based businesses.

Across the operating companies he has built and led, Karl has developed and managed brands, websites, market positioning, digital content, sales collateral and executive communications. His brand strategy spans the full customer-facing expression: logos, typography, packaging, websites, messaging, sales and marketing. He connects those choices to the audience, commercial priorities and experience the business needs to deliver. Through The Studio, a KSIG Advisors brand, he collaborates with Emerson’s branding, photography and content expertise and Stacey’s interiors and styling.
