View serviceWeb, mobile, AI and growth services in one UK studio
Synextai is a UK software development company for teams that need shipped product, not another deck. We design and build websites, mobile apps, AI features and demand systems that share one roadmap.
What we actually deliver
Most briefs that reach us sit at the join between product and growth. A storefront that needs better UX and paid media. A SaaS roadmap that needs Laravel engineering and SEO that wins hire-intent queries. An operations team that wants a private assistant without leaking data. We take those briefs seriously and keep the work connected.
Start with a service group if you are still shaping scope: web development, mobile app development, AI solutions, or digital marketing. Each hub lists the concrete offerings underneath.
Web and bespoke software
Our web practice covers website UI/UX, custom CMS development, custom web application development UK teams can maintain, and ecommerce website development. We favour clear architecture, editor-friendly workflows and performance that holds under real traffic.
Mobile products people keep
Need native depth or shared code? See iOS app development, Android app development, Flutter app development, and mobile app UI/UX. Store readiness and retention journeys are part of the plan, not an afterthought.
AI that earns its place
We build generative AI features, RAG chatbot systems over private knowledge, AI voice agents, and machine learning for forecasting and scoring. Evaluation, access control and cost visibility come with the feature.
Digital marketing tied to the product
Growth work covers B2B SEO for software companies, Google Ads and PPC, B2B social media, and technical content writing. Because we also ship the pages and apps, campaign ideas do not die in a backlog.
How to start
Browse the categories above, read a service page that matches your brief, then book a consultation or contact the UK team. Bring goals, constraints and a rough timeline. We will tell you what we would do first.
