Case study

Roboto converged Slingshot Bio's WordPress and Shopify sites into one headless Shopify build on Next.js and Sanity, instrumented end to end and AI-ready.

Your Sanity studio, looked after by people who build them for a living. Upgrades, schema changes, incident response and editor support on a monthly retainer, whether we built your studio or you inherited it from an agency that stopped replying.
Named retainer, no mystery scope
Every Sanity studio needs someone on the hook for it. Dependencies age, schemas outgrow their first design, editors hit walls, and the agency that built it has often moved on. The retainer puts our team on that hook: the same people who ship production studios, author the official Sanity Learn courses and maintain Turbo Start Sanity, pointed at keeping yours healthy.
Upgrades and maintenance. Studio versions, plugin updates and dependency patches applied on a schedule, tested before they touch production.
Schema evolution. Content models drift out of date as the business changes. New page types, field changes and validation rules get shipped through the retainer instead of queueing for a project.
Incident response. Production issues acknowledged the same business day, with a priority queue ahead of routine work. Specific response windows are agreed per plan.
Performance and SEO monitoring. Core Web Vitals, structured data and index coverage watched month over month, so regressions get caught by us rather than by your traffic report.
Editor support and training. A channel for your editors' questions, and training when new team members join or new studio features land.
Monthly improvements allowance. The small items that never justify a project: a new component here, a workflow tweak there. They get shipped instead of listed.
Half the studios we support were built by someone else. The pattern is familiar by now: the build shipped, the invoices stopped, the replies slowed, and the team is left with a studio nobody fully understands. We start those engagements with an audit, tell you honestly what state the build is in, and then either stabilise what's there or fix the schema problems that are worth fixing. Mario Testino's team came to us exactly this way, and the audit-first approach is why that story gets told in our reviews.
I've never had such a good experience with an agency. They jumped in to get our site usable, and righted all the problems the previous agency left.

Digital Lead, Mario Testino
Sanity's partner directory lists 218 agencies and stars 15 of them. We're one of the 15, which matters for support in a practical way: when an issue is genuinely on the platform side, we have a direct line to Sanity rather than a ticket queue.
Studio and dependency upgrades, schema changes as your content needs evolve, incident response for production issues, performance and SEO monitoring, editor support and training, and a monthly allowance for small improvements. The exact scope is agreed at sign-up so there's no ambiguity about what counts.
No. Inherited builds are half the point of the retainer. We audit the existing studio first, tell you honestly what state it's in, and either stabilise it as-is or propose the schema fixes worth making. We've taken over Sanity builds from agencies that ghosted, and from agencies that just moved on.
Production incidents get acknowledged the same business day and jump the queue. Routine requests are scheduled into the monthly allowance. Specific response windows are agreed per plan at sign-up, in writing, because a support promise that lives in a sales call isn't one.
A fixed monthly fee scoped to your studio's size and how much change you push through it. We'll give you the number on a scoping call after a look at the build, because quoting blind is how retainers end up mispriced and resented on both sides.
Yes. We're a Contentful Silver Solution Partner, and the same retainer structure works for Contentful spaces. Mention it on the scoping call and we'll shape the plan accordingly.
Net-new builds, full redesigns and large migrations are project work, scoped separately. The retainer keeps a production studio healthy and moving; it isn't a discounted way to buy a rebuild. When retainer work uncovers something bigger, we'll flag it with options rather than quietly burning the allowance on it.
Because most Sanity problems are schema and content-model problems wearing a frontend costume. A generalist patches the symptom; we've built enough studios to recognise the cause. Being one of 15 starred partners in Sanity's directory also means a direct line to Sanity when a platform issue is genuinely on their side.
Ready for support that answers?
Tell us about your studio. Whether we built it, another agency built it, or nobody remembers who built it, the first step is the same 20-minute call: what you're running, what keeps breaking, and what a sensible retainer looks like for it.
