Devstars is a specialist digital consultancy that builds custom web software and delivers strategic marketing direction for ambitious businesses. We're not a template agency. Every system we build is engineered from the ground up to solve your specific challenges, whether that's a queue-timing platform for a major airport, secure research tools for government defence, or a high-converting property portal integrated with SalesForce. Founded in 2003, we've spent over two decades helping organisations from funded start-ups to FTSE-listed enterprises transform how they connect with customers online. Our client relationships last years, not months. We still work with partners we started with in 2016. Our Four Pillars1. Bespoke Software Development We build custom web applications, platforms, and systems tailored to your requirements. Complex CRM integrations, multi-vendor marketplaces, secure portals, scalable architectures. If your needs don't fit existing platforms, we build what doesn't exist yet. 2. Custom WordPress Expertise Most WordPress sites are slow, bloated, and vulnerable. Ours aren't. We treat WordPress like a high-performance engine, building only what's needed. The result: sites that load faster, rank higher, and convert better. We rescued a 56-location salon chain from plugin disaster, cutting load times by 60% and supporting £6.7M annual turnover. 3. Marketing Direction & Strategy Technology without strategy is expensive infrastructure. We provide conversion rate optimisation, multi-platform search strategy, and Generative Engine Optimisation (GEO) for AI-era visibility. With 59% of Google searches now ending without a click, your customers research in ChatGPT and Perplexity before visiting your website. We help you get recommended by AI tools, not just ranked by search engines. 4. AI-Powered Research & Content Support We use AI strategically to amplify human expertise. AI-assisted market research, content production at scale with editorial oversight, and structured data optimisation for AI comprehension. AI handles volume. Humans provide judgement.
