A second opinion before a major technical decision

When a vendor, contractor, or auditor says your software needs a major rebuild, a long delay, or expensive remediation, it can be hard to know whether the advice is sound. A founder preparing to launch, for example, might be told the platform must be rebuilt from scratch, with no independent way to judge whether that is true.

Willowbark provides an independent technical second opinion in plain English, so you can decide with confidence. We can give you a written opinion or launch-risk review without becoming your development vendor.

Not staff augmentation. Not generic software development.

Willowbark provides independent judgment for situations where technical decisions have business consequences. Engagements focus on understanding risk, capability, readiness, and the practical steps needed to improve outcomes.

The value is not a checklist. It is an experienced, CTO-level perspective on whether a company's technology, team, architecture, and operating model can support an investment thesis, a growth plan, or a strategic decision.
