Tailored for High-Velocity Startups & Established Operators
Technical bottlenecks look different at a 12-person Seed startup in London or New York than at a profitable 20-year operating business modernizing its core workflows. We structure every engagement around your commercial stage.
US & UK Startups (1–30 Employees)
5–10 year old SaaS or marketplace companies trapped on brittle v1 monoliths where technical debt blocks AI features, enterprise integrations, and developer retention.
Established UK & US Businesses Making the Tech Shift
Profitable, long-running UK & US businesses (logistics, finance, healthcare, legal, property, manufacturing, services) ready to turn manual or legacy operations into a modern digital competitive moat.
4 Signals You Need Immediate CTO Intervention
- Core revenue runs on a 7–15 year old system only one retiring developer or vendor understands
- Staff spend hundreds of hours copying data across spreadsheets, emails, CRM, and accounting tools
- Customers expect modern self-serve portals, mobile access, and instant AI workflows your stack cannot support
- You were burned before—or fear getting burned—by a £150k / $200k agency "digital transformation" project

How GotYourTech Compares to Status Quo Alternatives
Dev agencies profit from longer hours and ground-up rewrites. Unassisted teams accumulate silent risk. Our incentives are 100% aligned with your P&L and valuation.
| Dimension | Without Senior CTO | Typical Agency / Junior Lead | GotYourTech Principal CTO |
|---|---|---|---|
| Migration Risk | Aging system eventually fails or blocks growth | 12-month "big bang" rebuilds that run 2x over budget | Incremental 30–90 day phases running safely beside live ops |
| Build vs. Buy Advice | Patchwork of 20 disconnected SaaS tools | Wants to custom-code everything to maximize billable hours | Buys commodity SaaS; custom-builds only your competitive moat |
| Executive Translation | Leadership intimidated by technical jargon | Speaks ticket jargon, ignores P&L reality | Board-level commercial clarity tied to margin & staff hours saved |
