Making major architectural decisions without a senior technical voice in the room?
Engineering team shipping slowly and you're not sure whether it's talent, process, or codebase?
Your company is at the stage where every technical decision has strategic consequences. Which cloud architecture scales to 10x? Should you build or buy the data infrastructure? How do you evaluate a team that's shipping slowly -- is it a people problem, a process problem, or a technical debt problem?
These decisions require a CTO-level perspective. If you're not ready to hire a full-time CTO, or you need a second opinion before a major technical investment, we provide fractional CTO services and engineering advisory for growing companies.
Technical strategy, architecture decisions, and build-vs-buy guidance
Engineering team assessment -- velocity, quality, and organisational gaps
CTO coverage during hiring gaps or founder-to-CTO transitions
Defined engagement scope -- not an open-ended retainer
Technical decisions compound. A database schema chosen for MVP simplicity becomes a migration project that costs 6 months of engineering time at scale. A monolithic architecture chosen to ship fast becomes a scaling constraint that adds 3 weeks to every feature. A third-party dependency chosen for speed becomes a vendor lock-in that limits your product options.
These decisions don't announce themselves as consequential. They look like small architectural choices at the time. A fractional CTO's job is to identify which decisions are load-bearing before they're made -- not after they've caused the expensive problem.
Translating business goals into a coherent technical strategy. Which capabilities need to be built, which need to be bought, and in what order. How to sequence technical investments so the platform grows in the right direction for your business model.
Reviewing major architectural decisions before they're made -- system design, data architecture, integration strategy, infrastructure choices. Identifying the load-bearing decisions and their long-term consequences before you're committed to them.
Structured assessment of your engineering team's velocity, quality, and organisational design. Identifying the root cause of delivery problems -- technical debt, process gaps, team structure, or skills -- and producing a concrete remediation plan.
Objective evaluation of the build-vs-buy decision for specific capabilities -- data infrastructure, AI tools, payment processing, identity, and analytics. Including long-term total cost of ownership, vendor risk, and the opportunity cost of internal engineering time.
Technical due diligence for investment decisions -- evaluating a target company's codebase, architecture, team, and technical debt. Producing a structured findings report and risk assessment for investors and acquirers.
CTO coverage during leadership transitions -- between a departing CTO and a hire, during a technical founder's transition to a non-technical CEO role, or while an engineering manager is being evaluated for promotion to CTO.
Tell us the context. We'll structure the right engagement to give you the answer.
AI Consulting -- Where AI creates value in your specific operation
Product Discovery Technical Strategy -- Technical strategy before committing to a build
Custom Software Development -- Execution after the strategy is defined
Enterprise Software Development -- Large-scale platform engineering
Tell us the decision you're facing or the problem you're trying to diagnose. We'll structure the right engagement.
Frequently asked questions
A fractional CTO provides the technical leadership and strategic input a full-time CTO would provide, for a defined number of days per week or month. This includes technology strategy and roadmap decisions, architecture review and guidance on major technical choices, engineering team assessment and hiring criteria, vendor and technology evaluation, investor and board technical communications, and acting as the senior technical voice in product and business discussions. The scope is defined upfront -- it's not an open-ended advisory relationship.
Fractional CTO is most valuable for: post-Series A or Series B companies that have a product and engineering team but no CTO; founder-led technical teams where the technical founder needs a strategic partner to pressure-test decisions; companies in a CTO transition (between CTOs or promoting an engineering manager into the role); and companies facing a major technical inflection point -- a re-architecture, a platform migration, or a significant scaling challenge -- that needs senior technical oversight.
Engineering advisory is a narrower engagement -- typically a specific technical question, an architecture review, or an assessment of an engineering team or codebase. Fractional CTO is an ongoing engagement where we become part of your leadership team for a defined period. Advisory is appropriate when you have a specific decision to make. Fractional CTO is appropriate when you need continuous technical leadership.
We start with a fixed-scope diagnostic -- 2--3 weeks assessing your current architecture, engineering processes, team structure, and technical roadmap. You get a structured findings report and a set of prioritised recommendations. From there, you can continue with an ongoing fractional engagement or use the advisory output to hire or promote internally. We design every engagement with a defined end state, not perpetual dependency.
Yes. Engineering team assessments are one of the most common advisory requests. We evaluate team structure, technical skills, engineering processes, code quality, and delivery patterns. The output is a structured report that identifies the root cause of velocity or quality problems -- which is rarely simply "the team isn't good enough." It's usually a combination of unclear ownership, missing processes, technical debt in specific areas, or tooling gaps that we can fix.
