Clownmind
Commerce engineering

Online stores engineered for conversion, not just for launch day

We design, build and operate ecommerce experiences that hold up under real traffic — fast catalogues, honest checkouts and a merchandising surface your team can actually use.

  • TypeScript
  • GraphQL
  • Stripe

Ecommerce Development

Most storefronts are slow because nobody owns performance after go-live. We work the other way around: a budget for page weight, a budget for time-to-interactive, and a release process that fails the build when either is breached.

Clownmind teams pair a commerce architect with a product designer from day one, so catalogue structure, search behaviour and checkout logic are decided together instead of being patched later.

How we work

Four steps, and you can stop after any of them

Every stage produces something you own outright. Nothing is held hostage to the next invoice.

  1. 01

    Framing week

    A paid week where we map the constraints, the existing systems and what success has to look like in numbers. You keep the output whether or not we continue.

  2. 02

    Architecture & plan

    A written technical plan with the trade-offs made explicit, a milestone schedule, and a fixed budget band for the first release.

  3. 03

    Build in the open

    Two-week increments, a preview URL from day three, and a Slack channel where your team can see the work rather than wait for a demo.

  4. 04

    Launch & operate

    Load testing, runbooks and monitoring before go-live, then a support window while your team takes the wheel — or a retainer if you would rather we kept it.

Testimonials

What clients say when we are not in the room

These are lightly edited excerpts from reference calls, published with permission.

They rebuilt our checkout in nine weeks and then spent another two arguing us out of three features we did not need. Conversion went up either way. That mix of speed and pushback is rare.

The framing week was worth the whole fee on its own. We came in wanting a replatform and left with a plan to fix search instead, which turned out to be the actual problem.
TFTomás FerreiraHead of Product · Meridiana Living
We had two agencies before this. Clownmind is the first one whose handover documentation our own engineers could read on a Friday and deploy from on a Monday.
DWDana WhitcombeCTO · Northlake Health
Their SEO people write code. I did not realise how much time we had wasted on audits nobody could implement until findings started shipping in the same sprint.
KAKenji AoyamaGrowth Director · Studio Ferrous
Peak week went by without a single incident. They rehearsed the load twice in September and found a caching bug that would have cost us the whole of Black Friday.
ANAyesha NkemdirimDirector of Ecommerce · Verdant Supply Co.
They told us not to build the AI feature we asked for and explained why in writing. Six months later that was clearly the right call. I trust the next recommendation more because of it.

FAQ

Ecommerce Development: the questions we get asked

If yours is not covered, ask it directly — the reply comes from whoever would lead the work.

With a paid framing week. Two of our people read the existing code, talk to whoever operates the system daily, and produce a written technical plan covering approach, trade-offs, milestones and a budget band. You keep that plan regardless of what happens next.

The people you meet in the framing week. Clownmind runs senior-only delivery teams of three to five, and we do not hand projects to a second bench after the pitch. Next.js, TypeScript, GraphQL and the rest of the stack listed above are things our team uses daily, not things we subcontract.

Most first releases land between eight and sixteen weeks depending on integration surface. We ship in two-week increments with a preview environment from day three, so there is something real to look at long before launch.

Load testing, runbooks and monitoring go in before go-live. After that you either take it in-house with a documented handover — which is what we design for — or keep us on a retainer for operations and continued delivery.

Yes, from the first commit. Work happens in your repository, under your organisation, on your cloud accounts. There is no proprietary Clownmind framework you have to keep paying to license.
