View all FAQs
Synextai delivers web development, mobile app development, AI solutions, and digital marketing under one UK based team. That includes custom websites, CMS and e-commerce platforms, iOS and Android apps, generative and voice AI, plus SEO and growth campaigns tied to the products we build.
We cover Website UI/UX, CMS platforms, custom web applications, and e-commerce. Engagements can be fixed-scope launches, product team extensions, or ongoing optimisation retainers.
It depends on roadmap, device APIs, and team skills. We recommend Flutter or React Native when shared code accelerates delivery, and native Swift/Kotlin when platform depth or performance is critical.
Generative AI copilots, RAG over private knowledge, voice agents, and custom predictive models. We start from a commercial use case, not a model preference.
SEO and content strategy, social media marketing, PPC and paid media, and content writing. Channels are planned together so they reinforce the same pipeline goals.
Most MVPs and focused product releases land in 8 to 16 weeks, depending on scope, integrations, and compliance needs. Larger platforms are delivered in clear phases with two week sprints, staging demos, and milestones you can track from day one.

UK software studio

A software development company that builds and grows the same product

Synextai is a UK studio for teams that need websites, mobile apps, AI features and demand systems on one plan. We work from discovery to launch, then keep the work moving with SEO, paid media and measurement.

What we build

Product and growth usually fail in the gaps between agencies. A site ships without search intent. An app launches without analytics. An AI demo never reaches production data. We keep those pieces together. Start with our services if you want the full map, or go straight to web development, mobile app development, AI solutions or digital marketing.

Who we help

Most clients are UK software, SaaS, healthcare, finance and retail teams. Some need a rebuild. Some need a first mobile release. Some need an assistant over private documents. We shape the first slice around a commercial outcome, then expand. See how that changes by industry and which technologies we ship with.

How a typical engagement starts

Bring the problem, the users and the constraints. We reply within one UK business day, then suggest a discovery call or a written next step. The call covers scope, risks, sequence and whether we are the right partner. If we are, you get a clear plan rather than a generic proposal. Book a consultation or send a project brief.

Why teams stay with one studio

Engineering and marketing share the same backlog here. Landing pages, tracking and content can move with the product instead of waiting on a second vendor. That is the practical reason UK companies hire Synextai as a software development company rather than splitting build and growth across four retainers.
