What does a technical due diligence engagement look like?

We start with a 30-minute briefing to understand the target, your concerns, and timeline. From there, we access the codebase and infrastructure, conduct a structured assessment across code quality, architecture, security, scalability, and team capability, and deliver a comprehensive report with risk ratings and remediation estimates. Most engagements complete within two weeks.

How fast can you turn around a due diligence report?

Standard turnaround is 10 business days from codebase access. For time-sensitive deals, we offer expedited assessments in 5 business days. We'll confirm feasibility during the briefing call.

Do you work with early-stage or growth-stage companies?

Both. For pre-seed and seed companies, we focus on MVP viability, founder technical capability, and architecture decisions that will compound. For Series B and beyond, we assess scalability, security maturity, technical debt levels, and team structure. The depth scales with the stage.

How do you handle confidentiality?

Every engagement begins with a mutual NDA. We operate under strict information barriers between portfolio companies and funds. Our team follows enterprise-grade security practices for code access and report handling. We can work within your existing NDA framework if preferred.

What's the pricing model?

Indicative pricing — Technical due diligence is project-priced based on scope — typically £8,000–£25,000 for seed to Series B targets. Fractional CTO and ongoing advisory work is retainer-based, starting at £5,000 per month. We'll scope and quote during the briefing call. Final pricing depends on scope and complexity.

The Technical Blind Spot in Every Deal

Nearly half of all venture capital now flows into AI and deep-tech companies. Yet most investment teams lack the in-house expertise to evaluate what they're actually buying.

Code quality, architecture decisions, security posture, scalability ceilings — these aren't visible in a pitch deck. They're buried in repositories, infrastructure configs, and technical debt that compounds silently until it becomes a capital problem.

Bad technology doesn't announce itself. It surfaces as missed milestones, ballooning burn rates, and replatforming conversations that should have happened before the term sheet. By then, you're not investing in growth — you're funding a rescue.

What We Deliver

We're not a dev shop filling seats. We're a technical consultancy that builds and evaluates production-grade systems — full-stack platforms, cross-device applications, payment infrastructure, AI pipelines, and everything underneath. Six capabilities across your entire deal lifecycle.

Technical Due Diligence

The problem: A pitch deck can't tell you about the authentication bypass in production, the monolith that won't survive 10x load, or the infrastructure costs that double every quarter.

What we deliver: A full-stack audit across frontend, backend, mobile, infrastructure, CI/CD, and data pipelines. We quantify technical debt in engineering hours and cost, assess security posture against OWASP and cloud-native benchmarks, evaluate team capability and velocity, and deliver a risk-weighted remediation roadmap with go/no-go signals. Typical turnaround: 10 business days.

Fractional CTO

The problem: Your portfolio company needs a CTO, not a consultant who sends slide decks. Engineering decisions are stalling, technical hiring is directionless, and nobody can speak to the board about technology with authority.

What we deliver: Hands-on technical leadership embedded in your portfolio company. We set architecture direction, establish CI/CD and DevOps practices, manage vendor relationships, lead technical hiring, and represent the company in board meetings and fundraising rounds. We've built engineering teams from zero to twenty. This isn't advisory — it's execution.

Technical Roadmapping

The problem: Capital's been deployed, but engineering is building features without a plan tied to business outcomes. There's no clear path from current state to the platform the company actually needs.

What we deliver: Milestone-driven roadmaps anchored to business KPIs, not feature wishlists. We cover capacity planning, infrastructure scaling, build-vs-buy analysis, and technology selection — including cross-device platform architecture with shared backends, payment system integration, auth and identity systems, and data layer design. Every milestone maps to measurable business value.

AI Readiness Assessment

The problem: The company claims proprietary AI, but you can't tell whether it's a genuine competitive moat or a prompt wrapper with a nice UI. With half of all VC funding going to AI, the cost of getting this wrong is enormous.

What we deliver: A rigorous evaluation of model architecture, training pipelines, data quality, inference costs, and competitive defensibility. We assess regulatory compliance against EU AI Act and GDPR, evaluate data governance practices, and identify where AI could create value but isn't being applied. You get a clear verdict: what's real, what's marketing, and what it would cost to close the gap.

Platform Engineering & Acceleration

The problem: Your portfolio company has funding and a validated idea, but no engineering team capable of building the production-grade platform they need to scale.

What we deliver: End-to-end platform builds — not prototypes. Cross-device applications with shared backends, payment processing via Stripe or Adyen, authentication and identity with OAuth, SSO, and MFA, real-time data pipelines, and AI-powered analytics dashboards. We ship on modern stacks — React, Next.js, React Native, Node, Python, Go — with CI/CD, monitoring, and production-ready infrastructure from day one.

Legacy System Modernisation

The problem: The portfolio company is trapped on an end-of-life monolith, a vendor-locked platform, or a codebase nobody wants to touch. Every sprint is slower than the last, and a full replatforming project would burn half the runway.

What we deliver: Stabilise first, then modernise incrementally. We use strangler fig patterns and incremental migration to replace legacy systems piece by piece — with zero-downtime cutover and no eighteen-month death march. The result: a modern, maintainable platform that becomes an asset on the balance sheet instead of a risk in the due diligence report.

Why VCs Choose Rogue

Technology Agnostic

We evaluate whatever your portfolio companies actually use — Python, Node, .NET, legacy PHP, Kubernetes, serverless, or something we haven't seen yet. No vendor partnerships biasing our recommendations.

Full Deal Lifecycle

Diligence before investment, CTO leadership after close, roadmapping for growth, and hands-on build when needed. One partner who already has context, not a new vendor at every stage.

AI-Native

AI isn't a service we bolted on last year. We build with it, evaluate it, and deploy it daily. When we assess an AI company's technical claims, we're drawing on deep, current expertise.

Right-Sized for Emerging Managers

Big Four firms charge Big Four rates and treat sub-£500M funds as an afterthought. We deliver the same rigour — code-level audits, architecture analysis, security review — at price points that make sense.

How It Works

Briefing

Tell us about the deal. We'll discuss the target company, your timeline, specific concerns, and what a useful deliverable looks like for your investment committee. Most briefing calls are 30 minutes.

Assessment

We go deep. Code audit, architecture review, security posture, team capability, scalability analysis — scoped to your deal. You receive a structured report with risk ratings, remediation costs, and clear recommendations. Typical turnaround: 10 business days.

Partnership

If you invest, we're already up to speed. Transition seamlessly into fractional CTO support, technical roadmapping, or hands-on acceleration for the portfolio company. No re-onboarding, no lost context.
