We find the real problem first: the constraint slowing the business and the one number it is costing you. Then we prescribe the path: salvage, refactor, rebuild, or a build plan with costs.
Reviews from £1,500Kyln is a London design-and-build agency with published prices. Two ways in: productised Website Care on a flat monthly plan from £175, or a bespoke Product & Platform build entered through a paid review from £1,500. Apps and cloud estates have separate rate-card floors below. Edit the site yourself with Kyln CMS, or leave it to us. You own the site, the code and the domain.
Platform costs (hosting, AI, email, storage) billed at cost · overage £125/hr · extra development £650/day · annual Website Care: pay for 10 months, get 12 · minimum 3 months · you own the site, the code and the domain.
Separate from Website Care. Entered after a paid onboarding audit. Critical 24/7 tiers are not published until an on-call rota or named delivery partner is live.
Engineering availability and incident ownership for a custom app or portal. Quoted after a paid onboarding audit.
Ops ownership for a cloud environment. Cloud consumption stays pass-through — never an all-in flat.
Onboarding audit: websites £250–£750 · apps and infrastructure £1,500–£5,000 · included hours do not roll · project and feature work always outside the retainer · minimum 3 months.
Got a vibe-coded prototype, a serious idea, or a manual process eating your week? We find the real constraint and the number it is costing you, then prescribe the fix: salvage, refactor, rebuild, or a build plan.

Reviews from £1,500A scoped product, MVP or platform build. Auth, data, security, payments, deployment. Priced after the review, not from a guessed feature list.
From ~£20kApps land on Application Support after a paid audit. Where you need it, fractional-CTO direction: architecture, security, roadmap, investor-ready delivery.
App Assurance from £750/mo · CTO from £5,000/moWhen a site isn't enough, this is where we build products and platforms. You own the code, the data and the deployment.
Vibe coding is cheap to start and expensive to keep. Google's 2026 report puts the crossover at the point where unmaintained AI code costs 3-10× more per feature to change. We spend a little more up front so it does not bite you later.
