Index / Growth Retainer
Engineering on tap.
No project queue.
Monthly hours for retailers and brands who hate ringing someone every time they need something built. Custom dev, CRO, agent-readiness, performance — under one rolling contract you can cancel any time.
02 / What's included
Five things, one bill.
01
Engineering hours
Custom development time used however you need it — new features, bug fixes, integrations, performance work, agent-readiness improvements. Unused hours roll over.
02
CRO & optimisation
Continuous testing on product pages, checkout, search, navigation. Built on the actual data, not best-practice slides.
03
Performance & uptime
Core Web Vitals tracked monthly. Performance regressions caught before they reach customers. We watch the boring graphs so you don't have to.
04
Agent & AI readiness
Ongoing work to keep your store discoverable by ChatGPT, Perplexity, Google AI Overviews, and Shopify Agentic Storefronts as they evolve. The standards move; we move with them.
05
Strategy & reviews
Monthly call to review what shipped, what moved the numbers, and what to build next. No project-manager middlemen — talk to whoever built it.
03 / Who it's for
Past launch. Something always needs building.
Established stores past launch — usually £500k+ annual revenue
Multi-SKU retailers and brands where something always needs building
Operators tired of agencies vanishing after the project signs off
Teams that want engineering on tap, without hiring an in-house developer
