Software Architecture Consulting & Technical Due Diligence

Most architecture problems are cheap to fix on paper and expensive to fix in production. We review how your system is built, how it will behave under the load and change you expect, and what it will cost to keep running. You get a clear picture of the risks and a prioritised plan, before you scale, raise, rewrite or commit budget.

01

Software architecture review

A software architecture review examines whether a system can support what the business needs next. We look at service boundaries, data models and access patterns, scaling limits, failure modes, security, observability and how easily the code can change. We talk to the people who run the system, because the real constraints are rarely in the diagrams.

02

Technical due diligence services

Technical due diligence is an independent assessment of a technology and the team behind it before a funding round, acquisition or major investment. We review the code, infrastructure, security posture, delivery practices, technical debt and key-person risk, then write up what is sound, what is risky, and what it would cost to fix.

03

Architecture for scale and change

Good architecture makes change easy. We help teams move from tangled systems to clean, modular ones through incremental refactoring that delivers value at each step, rather than big-bang rewrites. Where a rewrite genuinely is the right answer, we set out why and how to do it without stopping delivery.

04

Architecture for AI-assisted teams

When coding agents write much of the code, architecture decides how much of it is safe to review lightly. Clear module boundaries limit the blast radius of any one change, and a committed map of high-risk paths tells reviewers where to spend their attention. We design for both.

Common questions

What does a software architecture review include?

We assess service boundaries, data models, scaling limits, failure modes, security, observability and how easily the code can change. You receive a prioritised list of risks, what each one could cost you, and what to change first.

Who is technical due diligence for?

Founders preparing for a funding round, and companies or investors who want an independent view of a technology and its team before committing money.

What access do you need?

Read access to the code and infrastructure configuration, and time with the people who build and run the system. We do not need to change anything in your environment to complete a review.

Should we rewrite our system?

Usually not. Incremental refactoring tends to deliver value sooner and carry less risk. A rewrite can be right when the foundations cannot support the business, and a review will show whether yours is one of those cases.

Do you implement the recommendations?

We can. Depending on what you need, we can hand the plan to your team, guide them through it, or stay involved as your fractional CTO.

Ready to get started?

We work with a small number of companies at a time. If this is what you need, let's have a conversation.
