Willowbark Consulting LLC

Willowbark Consulting LLC is an independent technical advisory firm providing technical due diligence, technical health checks, and CTO-level advisory services to investors, founders, CEOs, CTOs, and the boards of software companies.

Leadership

Paul Julius

Willowbark is led by Paul Julius, an experienced CTO-level advisor, software delivery practitioner, and technical diligence consultant. Paul has worked across software architecture, engineering leadership, DevOps, cloud infrastructure, continuous improvement, and AI readiness over the course of a long career in the software industry.

Paul connects business, product, engineering, architecture, operations, and AI into a coherent view, which is what makes his assessments useful to investors and executive teams rather than just to other engineers.

Clients work directly with Paul Julius on every engagement, bringing senior CTO-level judgment to the assessment rather than passing the work through junior analysts.

His work spans early-stage companies and large enterprises, across industries including financial services, insurance, healthcare, SaaS, infrastructure, and enterprise software.

Why Willowbark

Why clients work with Willowbark

Independent technical judgment

Willowbark is not affiliated with vendors, platforms, or development shops. Findings reflect what is actually true about the technology and the team, without agenda.

Investor-focused reporting

Deliverables are structured for investment committees, boards, and executive audiences. Findings are tied to business implications, not technical detail alone.

CTO-level pattern recognition

Assessments draw on deep experience across software architecture, engineering organization, cloud and DevOps, delivery practices, and AI readiness accumulated across many companies and industries.

Practical recommendations, not generic findings

Willowbark does not produce boilerplate output. Recommendations reflect the specific company, the specific investment thesis, and the specific decisions that need to be made.

Technical observations connected to business risk

The value of a technical assessment is not the technical list. It is the ability to translate what was observed into investment risk, operational implications, and execution priorities.

What makes Willowbark different

Many technical due diligence and advisory providers are either too narrow (focused solely on code quality or security) or too generic (applying a standard checklist without investment-thesis context).

Willowbark assessments are grounded in the specific business situation. The question is not just "what is wrong with the technology?" It is "what does the technology tell us about the investment, the risk, and the path forward?"

That requires connecting technical observations to business implications, and that is the judgment Willowbark provides.
