Everything You Need to Know.

We are a development studio - not a strategy or consulting agency. We build what you brief us on. If you or your team has a hypothesis, test plan, or design ready, we take it from there and build it fast, clean, and QA-tested. If you need help thinking through strategy, we are happy to point you in the right direction - but our core value is in the execution.

Yes. If you are unsure whether a test can be built on your platform or within your tech stack, send us a brief and we will review it and let you know what is and is not possible before any work begins. We would rather tell you upfront than build something that does not work.

For most A/B tests - once we have a complete brief, design, and all required assets - we aim to build, QA, and deliver within 24 hours. This applies to standard experiment builds. More complex tests involving multi-step flows, personalisation, or custom logic may take longer. We always confirm the timeline before starting so there are no surprises.

Fill in the project brief form on our Contact page. Tell us what you need built, which platform you are using, what the goal is, and your timeline. The more detail you share, the faster we can confirm scope and cost. We respond within 24 hours with a confirmed scope, timeline, and fixed price.

Yes. You do not need a monthly plan to work with us. You can start with a single A/B test, landing page, or Shopify feature - no commitment required. If you find the work meets your standards, you can move to a monthly plan whenever you are ready.

Yes. We integrate into your existing workflow - whether that is Slack, email, Notion, Linear, Asana, or any other tool your team uses. We work as a silent development partner. Your clients and stakeholders never need to know we are involved unless you want them to.

Yes. All work is delivered under your brand with no Ceptrix branding anywhere. We sign NDAs on request and operate as your internal development team - building experiments, websites, and Shopify stores that your agency delivers to clients. Available on Growth and Scale plans, and on one-off projects on request.

One A/B test counts as one complete experiment build - including all variants, implementation on your chosen platform, QA testing across browsers and devices, and handoff notes. If a test has two variants (A and B), that is one test. If it has three variants (A, B, and C), that is still one test. Multi-page experiments that span more than one URL may count as more - we confirm this upfront.

Additional tests can be added at a per-test rate agreed before starting. We will always confirm the extra cost before building anything outside your plan. Alternatively, if you consistently need more than your plan allows, we can discuss upgrading to the next plan or a custom arrangement.

If a bug is caused by our build - we fix it immediately at no extra cost. We stand behind our work. If the issue is caused by a platform update, third-party script conflict, or a change made after delivery, we will assess and let you know the best way to resolve it quickly.

Yes. Every build comes with clear handoff notes explaining what was built, how it works, and anything the team needs to know to manage or extend it. For A/B tests this includes implementation notes, QA results, and any platform-specific details. For websites and Shopify builds this includes component notes and any custom logic explained.

We work however suits your team best - email, Slack, WhatsApp, or any project management tool you use. We provide regular updates and flag anything that needs your input before it becomes a delay. You will never have to chase us for an update.

Yes. If you need changes to a live experiment - adjusting targeting, fixing a bug, pausing a variant, or updating copy - we can turn this around fast. Post-launch support is available on all plans and on one-off projects at an agreed rate.

We do not offer free trial builds. Every build - regardless of size - takes real time and expertise. What we do offer is a free 15-minute discovery call where we review your requirements, answer any questions, and help you decide whether we are the right fit before you commit to anything.

For A/B tests: your test hypothesis or brief, which platform you are using, any design mockups or Figma files, and your target page URL. For websites: a Figma design file or written brief, your preferred tech stack if you have one, and any integrations needed. For Shopify: your current store URL if improving an existing store, the feature or page you need built, and any design files or references. The more detail you share upfront, the faster we can confirm scope and start.

In most cases we can start within 24–48 hours of receiving a complete brief and confirming scope and cost. If you have an urgent deadline, tell us in your brief and we will do our best to accommodate it. We do not take on more work than we can deliver properly - so if our current capacity means a slight delay, we will tell you honestly.
