(0 review)Rapid crowdtesting, QA and UX insight for ecommerce brands building and releasing faster with AI.
Digivante provides fully managed QA, user acceptance testing (UAT) and real-user testing for ecommerce brands and digital businesses. When teams are launching a new website, moving to a different ecommerce platform or managing frequent releases, testing can quickly stretch internal resources. We provide experienced QA professionals and flexible testing teams to take ownership of the work or support an existing team when additional capacity is needed. Our approach combines professional test management with a global community of real users, testing websites and applications across different devices, browsers and markets. This helps uncover issues that automated checks and internal testing alone may miss. We focus on the customer journeys that matter to ecommerce businesses, including registration, product discovery, basket, checkout, payments, promotions and account management. Our capabilities include exploratory testing, regression testing, usability testing, accessibility testing, cross-browser and device testing, localisation, payment testing and evaluation of AI-powered digital experiences. Whether you need ongoing QA support or additional testing capacity for a specific project, Digivante helps you identify problems earlier, reduce release risk and deliver more reliable digital experiences.4 works in EcommerceLocated in Cheltenham, United KingdomFrom €5,000 for EcommerceWorked in Automotive (+2)Speaks English11-50 membersCross Origin
5(4 reviews)Brand-led. Built to work online.
Cross Origin is a branding and web design agency based in Haywards Heath, Mid Sussex. We work with businesses and charities across Sussex and the South East to get their brand right, then build it to work online. The agency is led by founders Piero Barba, Creative Director, and Tim Vaughan, Digital Director, alongside Claire Scott, Head of Content Strategy, and Paul Block, Senior Designer. We keep the team small and senior, so the people you meet at the start are the people who do the work. Every project begins with understanding before design. We look at how your brand is seen today, what your audience needs to know, and where the gap sits between the organisation you are and the one people see. For clients who want that clarity first, our Diagnostics service is a structured brand and digital audit that shows exactly what needs to change. Our work then falls into three areas. Create covers brand strategy, positioning, messaging and visual identity. Build covers bespoke website design and development, with managed hosting and ongoing support. Grow covers digital marketing, including SEO and helping your business get understood and recommended by AI search tools such as ChatGPT, Google AI Overviews and Perplexity. Brand strategy and website build sit within one team. Your website isn't handed to a separate developer working from someone else's brief, so the decisions made in strategy carry through to the page structure, the copy and the code. Our clients include charities and property businesses, and we have built digital products with and for people with learning disabilities and autism. If your business has moved on and your brand hasn't, we'd be glad to talk. Brand-led.

5(3 reviews)Software built at the frontier of what's now possible.
RecommendedTake Off Labs is an AI-native software studio. We design, build, host and maintain products end to end, with AI woven through the process rather than bolted on at the end. Fourteen years of shipping, more than a hundred companies, across healthcare, fintech, e-commerce, real estate, logistics and maritime. We also build and run our own products, Doc2Data.io for document AI and Microsites.AI, which means the architecture decisions we recommend are ones we live with ourselves. How we work: prototypes that map real user journeys, AI-augmented build from the first commit, deployment on our own pipelines, error tracking and monitoring wired in from day one, and continuous improvement after launch. One studio owns the whole lifecycle, so nothing falls between teams. We scope with our own tooling and commit to fixed prices that hold. When scope changes, it goes through a formal change request rather than quietly appearing on an invoice.
