I specialise in getting B2B SaaS teams enterprise-ready. I remediate security and reliability gaps, ungoverned AI and compliance exposure that stalls enterprise deals and investor due diligence.
We work with
Here's exactly what's included.
Simple process. No time wasted.
A free 20-minute call. I'll learn your stack, your pain points, and where technical risk is costing you deals. By the end we'll both know if it makes sense to work together.
A one month deep-dive audit covering architecture, security, and AI risk. Deliverable: a Board-Ready Technical Risk Report with prioritised remediation steps.
Monthly retainer. I lead the architecture and security decisions. Security hardening, AI governance, ongoing fixes. $7,500/mo.
8+ years of UK government security engineering, applied to your stack. I provide the architectural oversight and hands-on delivery.
Full-stack security audit, IAM review, secrets management, and vulnerability scanning.
OWASP Top 10 for LLMs, ISO 42001 readiness, prompt injection mitigation, model access control, and data leakage prevention.
SOC 2 preparation, enterprise security questionnaires, audit readiness. We do the technical heavy lifting so your team isn't scrambling.
Infrastructure-as-code, CI/CD pipelines, and cloud architecture review and remediation.
Getting ready to raise or exit? I'll find what investors and acquirers will flag, and fix it before they do.
I act as your fractional CISO. I own the security strategy and make sure nothing falls through the cracks.

A free 20-minute call. I'll ask about your stack, your pain points, and where technical risk might be costing you. No prep needed. By the end we'll both know if it makes sense to work together.
A one month deep-dive across your architecture, security, and AI risk surface. You get a Board-Ready Technical Risk Report: prioritised findings, concrete remediation steps, and a document you can hand straight to investors or auditors.
Both. I personally lead the architecture and security decisions, and I handle the hands-on remediation, hardening, and infrastructure work. You get senior guidance that actually ships.
We cover prompt injection vulnerabilities, data leakage through model inputs/outputs, model access control and authentication, AI supply chain risks (third-party models and APIs), and governance frameworks for responsible AI deployment.
The 14-day satisfaction guarantee means you only pay if you're happy. No lock-in contracts, 30 days' notice to cancel. I cap the number of clients I take on so I can actually focus on your problems.
B2B SaaS companies, Seed to Series A, 10–50 engineers, selling to enterprise or regulated buyers. If you're losing deals to security questionnaires, prepping for due diligence, or shipping AI without governance, you're exactly who I built this for.
