About Campbell Yule
Operator, Advisor, and Builder in AEC Technology
I have spent more than 30 years operating at the intersection of architecture, BIM, SaaS, and vertical software businesses serving the built environment.
My career has not followed a single functional track. I have worked across product, engineering, commercial, operations, and capital — often simultaneously. I have founded companies, scaled them, transitioned business models, launched global SaaS products, and led successful exits. Today, I work with AEC, PropTech, and ConTech companies navigating the shift from early traction to institutional growth.
From Founder to Exit
I began in the AEC sector and went on to build and scale businesses within it.
As Managing Director and Group CEO of Cadimage Group, I led the business through sustained growth, achieving 5x revenue expansion and a 10x shareholder exit outcome. During this period, we introduced maintenance agreements early (2001), transitioned to subscription ahead of broader industry shifts (2013), and built recurring revenue foundations that ultimately covered the company's operating base.
Later, at GRAPHISOFT, I contributed to global subscription transformation initiatives and the launch of SaaS offerings such as BIMcloud. At Cerulean Labs, I founded and led the development of Codesign, an iOS-based concept design application for architects.
Across these roles, the pattern has been consistent: align product, commercial structure, and operational execution ahead of structural market shifts.
Where I Contribute
I work with founders and executive teams as:
- Strategic Advisor or Board-Level Partner
- Fractional C-Suite Operator (COO, CPO, CPTO, CSO)
- Growth and Subscription Transformation Lead
My role varies by engagement, but the objective is consistent: provide structured thinking, practical execution guidance, and commercial clarity during periods of transition.
How I Think About Scaling AEC Technology
Many AEC software businesses do not fail because of weak products. They struggle because product, revenue architecture, and organisational structure are misaligned.
- Clear product-market positioning within complex AEC workflows
- Engineering and product alignment around long-term platform direction
- Durable recurring revenue architecture
- Commercial discipline that supports sustainable ARR growth
- Organisational structure that matches the company's stage of maturity
Current Focus
My current focus is AEC Technology broadly defined — including PropTech and ConTech businesses building software platforms for the built environment.
- AI applications in BIM and spatial workflows
- Subscription and pricing evolution in vertical SaaS
- Capital readiness for growth-stage companies
- Structural alignment ahead of capital raising and beyond
