About Koseti
A Middlesbrough digital agency building websites, Laravel applications, and data analytics for UK businesses that want measurable results.
A digital agency based in Middlesbrough
Koseti is a digital agency based in Middlesbrough, North East England. We build websites, custom Laravel web applications, and data analytics solutions for UK businesses that want their digital presence to do measurable work rather than simply exist.
We work with businesses across Teesside and nationally. Our clients include Darraa, an African fashion e-commerce retailer based in Middlesbrough for whom we built a full WooCommerce store; Voco, an AI receptionist SaaS platform for UK trades businesses, built on Laravel, ElevenLabs, and Twilio; and Creekside Properties, a Sheffield property firm whose Wix site we rebuilt and whose SEO and digital marketing we continue to run. Every project is quoted at a fixed price with no hourly billing.
The full stack, covered by one small team
Web design is the foundation of most of what we do. We build in WordPress for businesses that need simplicity and easy content management, and in Laravel for those that need custom functionality, complex integrations, or a platform built to scale. We do not recommend one over the other until we understand the project properly.
Data analytics sits alongside every website we build. GA4 is configured before launch, conversion goals are defined, and we deliver a 30-day performance report so our clients know within a month whether the site is working. For businesses that want to go further, we build Looker Studio dashboards and reporting pipelines that bring web, sales, and operational data into a single view.
SEO, digital marketing, and graphic design round out what we offer. We are not a large agency with a separate department for each discipline. The same people who build your site are the ones who set up your analytics and advise on your search strategy, which means nothing gets lost in translation between teams.
Rooted in the Tees Valley, working across the UK
We are based in Middlesbrough because that is where the business started and where a good number of our local clients are. The Tees Valley has a real concentration of SMEs that are underserved by the digital agency market, particularly in data analytics and custom development, and we understand that market well.
That said, the majority of our work runs remotely and suits clients anywhere in the UK. Location only becomes relevant when a project benefits from a face-to-face meeting, which is less often than most agencies suggest.
Who runs Koseti
Koseti was co-founded by Kosi, a data analyst and business intelligence specialist with hands-on experience across analytics engineering, GA4 implementation, Looker Studio reporting, and digital marketing strategy. Kosi leads the data and analytics side of the business. The software development side, covering Laravel application builds, custom web applications, and technical architecture, is handled by Koseti's development lead. Between the two, the agency covers the full stack without relying on subcontractors for the core work.
