Local Ecosystem Snapshot
CleanTech, FinTech, Cyber, B2B SaaS, and established South West engineering & service businesses.
Whether you are scaling a Seed-funded SaaS platform in Bristol or leading digital transformation inside an established South West company, our Fractional CTOs own technical strategy, cloud efficiency, and engineering delivery end to end.
Unlike solo advisors who hand off slide decks, our Principal CTO practice brings two decades of active multi-tenant SaaS, cloud FinOps, legacy migration, and production AI engineering directly into your weekly leadership cadence—with 0% mandatory equity.
You raised—or are scaling—and cannot afford a bad hire.
You closed Seed or Series A funding (or budgeted for R&D expansion) and investors expect shipping velocity within 60 days. Senior candidates are juggling competing offers from and stealth spinouts.
We sequence the first 3–8 hires by business priority, author high-signal job specs, and run live architecture and debugging interviews through final offer.

Infrastructure and AI API spend are scaling faster than ARR. Capital is leaking into over-provisioned clusters, unindexed database queries, and sprawling vendor renewals.
We execute a 14-day FinOps and architectural audit—right-sizing compute, tuning queries, caching LLM pipelines, and cutting monthly cloud spend by 25%–50% with zero downtime.

You have live customers, an anxious engineering team, and active investor commitments—but no senior executive governing the codebase, credentials, or sprint cadence.
A Principal Fractional CTO steps in within 48 hours to secure infrastructure access, calm and lead the team, audit repositories, and eventually help recruit your permanent replacement.

Investors from are preparing a deep technical audit. Unresolved IP gaps, security debt, or weak unit economics can stall or re-price your term sheet.
We run a pre-diligence mock audit, assemble your technical data room, align SOC 2 / ISO 27001 / UK & EU GDPR controls, and defend your architecture directly in investor calls.

Customer usage is growing, but dashboards time out, deployments break existing workflows, and engineers spend half their week firefighting instead of shipping roadmap features.
We instrument APM observability, tune database bottlenecks, enforce automated CI/CD release gates, and restore sub-second reliability.
Read Bristol playbookYour core business has outgrown its legacy software.
An aging monolith, custom agency build, or manual ERP/spreadsheet patchwork is blocking new revenue lines, AI automation, and enterprise customer onboarding.
We architect a phased 90-day strangler-fig modernization roadmap—upgrading critical workflows incrementally with zero disruption to daily operations.

Customers and boards expect real AI workflows, but naive LLM wrappers risk hallucinations, GDPR/SOC 2 violations, and runaway inference costs.
We design enterprise-safe RAG pipelines, agentic tool-use guardrails, automated eval suites, and tiered model routing tailored to your domain data.
