I help investors make technology decisions that hold up commercially: before you commit, and across the portfolio after you have.

I'm Lee Goldsworthy. I've spent 22 years in technology: as an engineer in enterprise, as a founding CTO and CPO in startups, and as CTO at a venture-backed scale-up. Since 2023 I've worked as a Fractional CTO and Principal Advisor through High Growth Tech, from Perth and increasingly online.

Why investors engage me

An acquisition is on the table
A private equity buyer needed to know what a target's technology was worth, where the risk sat, and how much margin and growth it could carry after the deal.
A portco has an unusual proposal
A portfolio company wants to take an ambitious, unusual or risky direction, and the fund needs to know if it can work. I review the technology business case behind it and give you a straight answer on whether it's realistic, and what it would take.

How I work

Listen first, frame second, advise third. I say how strongly I hold a view, from an idea through to a recommendation, so you know what to weigh. I stay vendor-agnostic, and I tie every technical recommendation back to growth, velocity, cost or risk.

I’m not the right fit for a tool implementation with no teaching, a deep single-vendor specialism, or ongoing hands-on coding.

What clients say

I've worked with Lee over a number of years in the context of his fractional CTO work in our portfolio companies and our own technical due diligence.

He's been excellent to work with. Highly professional with deep technical knowledge and highly recommend him for this work.

Derek GerrardGeneral PartnerPurpose Ventures

He could go deep with our engineering team and earn their respect through his technical credibility, while also keeping the conversation anchored in business value and real-world outcomes.

Diana PittsCEOCoviu

Lee gave us a clear, well-structured view of where Loop Logics stands today, and backed it up with a thoughtful, prioritized set of recommendations to support our next phase of growth.

Aaron AlleyCOOLoop Logics

I've had the pleasure of working closely with Lee in his role as Fractional CTO at Paperly, and it's hard to articulate the impact he's had on our business.

Jak TidmanCOOPaperly

You took us from having a team with massively varying expertise in Agentic Engineering to establishing a consistent understanding and shared language.

Steven BearzattoCTOAutoGrab

Lee is one of those rare technical advisors who genuinely understands that you're building a business, not just a product.

Glen McIvorFounder & CEOSafer.app

Lee also has a knack for identifying second-order implications that others miss, which makes his advice particularly valuable when navigating periods of rapid technological change.

Christopher SmithFounderTHF

General sentiments were that it was really well reasoned and thought out, and aspirational but with a solid grounding in reality.

Nathan OehlmanCTOCoviu

As a non-technical founder, I found his guidance invaluable, he broke down our architecture in a way I could truly grasp, prioritising what was truly urgent while giving clarity on what could wait.

John ZadehFounder & CEODiscovery Alert

What stands out with Lee is that he brings clarity, ensures decisions are well-considered, and helps us move forward with confidence.
