15 Best Squarespace Web Design Companies in Europe (2026)

Gilzor works on web design and development projects through a broader product development process that covers planning, UI/UX, frontend work, QA, launch, and continued support. For Squarespace projects, its strongest contribution is around interface planning, responsive design, accessibility, performance, and the technical work needed around a customer-facing website.

The company works with startups, small and medium-sized businesses, and product teams. Its European presence includes Warsaw, giving companies access to a team that can handle both design questions and development requirements when a Squarespace website forms part of a wider digital product or marketing system.

SQSP Agency is a London studio focused specifically on Squarespace websites for consultants, creatives, therapists, professional services firms, and other service businesses. Its work covers new website builds, redesigns, mobile optimization, Squarespace SEO, structure, messaging, and continued support.

Projects are built on Squarespace with attention to visitor journeys and conversion paths rather than simply applying a pre-made visual template. The studio is a Squarespace Circle Gold Partner and works primarily with businesses in the UK and US, making it one of the more platform-focused choices in this list.

A-Listware provides web development and UI/UX resources through dedicated development teams and outsourced software delivery. Its web capabilities include responsive interfaces, ecommerce, websites, portals, integrations, frontend development, testing, and ongoing maintenance.

Within a Squarespace project, A-Listware is most relevant when a company needs technical or design capacity around the website, such as interface planning, custom frontend work, integrations, QA, or other digital systems connected to the site. Its headquarters are in the UK, with development operations distributed across European markets.

GOBO Creative is a UK-based web design studio with a long-running focus on Squarespace. The studio works on projects ranging from compact brochure websites to ecommerce builds and serves clients internationally.

Its Squarespace work is suited to businesses that want direct involvement from an experienced designer rather than a large production team. Design is approached around the individual business, with projects covering website structure, visuals, implementation, and launch. GOBO Creative is also part of the Squarespace Circle program and lists Platinum Partner status for 2026.

Lengreo combines web design and development with digital marketing, SEO, paid advertising, and lead generation. Its Squarespace offering covers website setup, page structure, landing pages, portfolio sections, ecommerce pages, forms, SEO fundamentals, and support around launch.

This combination is useful when the website needs to function as part of a larger acquisition strategy rather than as an isolated design project. Squarespace builds can be connected with content, search optimization, advertising, and lead generation work within the same engagement. Lengreo operates from Eindhoven in the Netherlands and works internationally.

Altitude combines Squarespace website design with UX, conversion-oriented design, and wider brand work. The UK agency is a Squarespace Circle Platinum Partner and has extensive experience building tailored websites on the platform.

Its portfolio includes commercial brands, charities, hospitality businesses, and other organizations, so the agency can handle projects with different content structures and audience needs. The service is a good match for organizations that want Squarespace's editable CMS while still requiring a website designed specifically around their brand rather than a lightly modified standard template.

Itexus handles custom web development projects from its European and international offices, including a location in Warsaw. Its work covers product design, frontend and backend development, web applications, prototypes, MVPs, and improvements to existing digital products.

For Squarespace-related projects, its capabilities are most useful when the website connects to a larger software environment or when a business also needs custom functionality outside the normal boundaries of a website builder. Product design and engineering can therefore complement the website layer without forcing the entire digital system into Squarespace.

Mar Mar Co. Studio is a London design studio working on brand identity and custom Squarespace websites. Its focus on founder-led companies and consultancies makes it especially relevant when the website needs to communicate positioning and visual identity clearly rather than simply provide basic company information.

Brand and website design are treated as connected parts of the project. This allows typography, visual language, messaging hierarchy, and individual Squarespace pages to develop from the same direction. It is a suitable approach for businesses that are updating their identity at the same time as rebuilding their website.

OSKI Solutions develops websites, web applications, and digital products from its European base in Tallinn. Its web capabilities span UI/UX design, responsive interfaces, frontend development, testing, deployment, system integration, and continued maintenance.

Its contribution to a Squarespace engagement is strongest where the project needs design, frontend expertise, QA, integrations, or surrounding software that extends beyond the site's standard content-management functions. The company works across modern frontend technologies and can also support more complex portals, SaaS products, and business applications when the requirements expand beyond a conventional marketing website.

Salter Square Digital focuses on Squarespace website design for service-based businesses in London and across the UK. Its projects can cover site structure, page design, messaging, calls to action, search foundations, and the practical details required before launch.

The studio also works with existing Squarespace websites, so companies do not necessarily need to replace their current site from scratch. Redesign work can address unclear services, weak content hierarchy, navigation problems, and limited enquiry paths while allowing the business to keep a familiar platform that staff can continue updating internally.

Mobian Studio works on digital products through dedicated engineering teams covering software development, mobile applications, AI, integrations, and post-launch support. The company operates from Tallinn and can handle both new product development and technical work around existing systems.

For a Squarespace-centered website project, Mobian is particularly relevant when additional software needs to sit behind or alongside the public website. That may include integrations, backend services, custom applications, automation, or other product functionality that is better developed separately while Squarespace remains the manageable content and presentation layer.

AUSTIN_SPACE is a UK-based Squarespace designer working with businesses around the country. The service centers on custom Squarespace websites handled by one designer from the initial project stages through completion.

This setup is particularly relevant for small and growing businesses that prefer a direct working relationship and want a website built specifically around their current brand, content, and business needs. The studio is based in Worcester and works remotely across the UK. It also participates in the Squarespace Circle partner program.

net-devs provides senior-led engineering across frontend development, enterprise software, cloud platforms, AI, and system modernization. Its frontend practice works with React, Angular, Vue, TypeScript, interface testing, wireframes, and prototyping.

The company fits Squarespace projects that involve technical work outside the builder itself, particularly when a marketing website needs to connect with applications, APIs, internal systems, or custom frontend components. Its project process runs from requirements and prototyping through development, QA, deployment, and continued iteration. The company operates from Warsaw, Poland.

Design Fibre is a UK-based web design business centered on Squarespace. Its work covers complete website redesigns, SEO improvements, and projects aimed at giving established businesses a clearer and more professional online presence.

The studio holds Squarespace Marketplace Expert status and is a Gold Circle Partner. That platform specialization makes it relevant to businesses that already know they want to remain within the Squarespace ecosystem and are looking for design help rather than broader custom software development. Existing Squarespace sites can also be refined instead of rebuilt on a different CMS.

SoftPro combines web application development with frontend, CMS, cloud, and custom software engineering. Its technology coverage includes Microsoft platforms, web applications, cloud environments, and CMS implementation, with a European base in Warsaw.

For Squarespace website projects, the company can be relevant where a simple website sits alongside more complex infrastructure, integrations, internal applications, or a custom digital platform. Its engineering background also makes it useful for organizations evaluating whether particular functionality should live inside a website builder or be implemented as a separate application connected to the public-facing site.
