14 Best Web Design and Marketing Companies in Europe (2026)

Gilzor combines web design with custom software and digital product development. Its work covers UX/UI design, front-end and back-end development, ecommerce, QA, product discovery, and continued improvements after launch. The company also supports product positioning, conversion-focused design, go-to-market planning, and marketing activities connected with launches and customer acquisition.

This setup is particularly relevant when a website is part of a wider digital product or commercial strategy rather than a standalone brochure site. Gilzor works with startups, SMBs, and product teams across areas including fintech, healthcare, education, and ecommerce.

Lengreo is a B2B-focused digital agency that connects website development with SEO, lead generation, content, and broader acquisition work. Its website services cover corporate sites, landing pages, and other web properties, while the SEO side includes technical and on-page optimization. This setup can suit companies that want the website planned around demand generation rather than treated as a separate branding project. Lengreo operates from European locations including the Netherlands and Ukraine.

OSKI Solutions designs and develops custom websites, landing pages, portals, and web applications with SEO and performance considerations built into the technical process. Its web offering covers responsive design, CMS implementation, Core Web Vitals, structured data, semantic markup, and search-friendly architecture. The company works with platforms and frameworks including WordPress, Umbraco, React, Next.js, Vue.js, and .NET.

Net-devs is an enterprise software engineering company based in Warsaw. Its core capabilities include modern frontend development with React, Angular, Vue, and TypeScript, along with backend engineering, cloud architecture, discovery, prototyping, testing, and deployment.

For ecommerce, Net-devs is better suited to stores or commerce systems that require substantial custom engineering than to standard platform theme projects. A business building a custom frontend, marketplace, API layer, automation system, or commerce application connected to enterprise software may find that broader technical focus useful. Its public positioning remains centered on enterprise software rather than ecommerce as a standalone specialty.

Mobian Studio is a Tallinn-based European software development company working on end-to-end digital product development, including wireframing, backend systems, APIs, cloud infrastructure, QA, and post-launch support. Its broader offering is centered more on product engineering than on ecommerce platforms specifically.

Published ecommerce listings associate Mobian with ecommerce software development and Shopify-related support. For ecommerce buyers, that makes the company more relevant where store functionality is part of a wider custom software requirement rather than a conventional design-only engagement.

A-listware combines web design with software engineering, which makes it relevant for websites that need custom functionality beyond presentation pages. Its offering covers responsive web design, web application design, website redesign, UI and UX, ecommerce design, development, integrations, QA, and ongoing support.

The company can work on standard websites as well as portals and more involved web applications. A-listware maintains a UK office in St. Leonards-On-Sea and supports clients through distributed engineering teams.

Itexus develops custom websites alongside larger web applications and digital products. Its website process covers planning, information architecture, UX/UI design, frontend and backend engineering, third-party integrations, SEO setup, QA, performance optimization, deployment, and support.

The company is particularly relevant where a website may later connect with a customer portal, financial platform, mobile application, or other custom software. Its broader project experience also makes it better suited to technically involved builds than design-only website studios.

DEPT combines experience design, engineering, creative services, media, and growth marketing within one international agency. Its service structure is useful for organizations that want website or digital experience work connected directly with wider marketing operations rather than delivered as separate projects.

The agency works across brand experiences, ecommerce, engineering, customer journeys, media, and digital marketing. Its European presence is substantial, with headquarters in Amsterdam and operations across multiple EMEA markets.

Bird Marketing is a UK digital agency working across technical web services, digital marketing, and creative work. Its web capabilities include website design, ecommerce, and enterprise web projects, while the marketing side covers services intended to improve online visibility and commercial performance.

The combination works well for businesses that want design, development, and acquisition activities managed by the same agency. Bird has offices in London, Essex, and Glasgow, giving clients several UK locations for project delivery and support.

Propeller combines bespoke web design and development with SEO, paid media, conversion rate optimization, social media, digital strategy, and analytics. Its website practice covers new builds, ecommerce, replatforming, optimization, and UX/UI design.

This connected approach can be useful for businesses that do not want the website team and performance marketing team working independently. Propeller can use campaign and conversion data to inform website improvements after launch rather than treating the site as a finished one-off project.

Gripped focuses specifically on B2B SaaS and technology companies. Its services connect website design and development with demand generation, account-based marketing, SEO, GEO, paid search, paid social, positioning, and go-to-market strategy.

Website projects are built around B2B buying journeys rather than visual design alone. The agency can develop corporate sites and landing pages while coordinating those assets with paid and organic acquisition programs. This narrow industry focus makes Gripped especially relevant to established SaaS businesses and technology providers.

Hallam operates as a full-service digital agency with a long-standing focus on search and online marketing. Its capabilities span website design and development, SEO, PPC, content marketing, digital PR, social media, ecommerce, email marketing, and conversion optimization.

The service mix makes Hallam suitable for organizations looking to redesign or develop a website while keeping organic search, paid acquisition, content, and conversion strategy within the same agency relationship. The company operates from the UK market.

Koozai is a UK digital marketing agency with a strong emphasis on SEO, paid media, digital PR, content, and broader marketing strategy. Its work is particularly relevant when a website project needs to be shaped around search demand, content structure, and acquisition rather than treated primarily as a visual exercise.

For businesses reviewing agencies, Koozai is most applicable where website improvements, landing pages, content architecture, and ongoing marketing activity need to work toward the same visibility and conversion objectives.

Blend focuses on B2B inbound marketing, websites, HubSpot, SEO, lead nurturing, and sales enablement. Its website offering is closely connected with inbound marketing and CRM workflows, which makes the agency particularly relevant for technology companies with longer B2B sales cycles.

Businesses using HubSpot or planning to connect their website with marketing automation and lead management can keep the technical website work and inbound program under the same provider. Blend is based in the UK and works extensively with technology businesses.
