biggest web design companies
Which agencies dominate web design in 2025, how they differ by services and price, and how to pick the right partner for your business — from enterprise work to budget-friendly options.
What we mean by "biggest web design companies"
"Biggest" can mean revenue, headcount, global footprint or breadth of digital services. This guide focuses on sizable digital agencies and consultancies that deliver large-scale web design projects for enterprise and national brands in 2025 — plus where they excel and who they aren't right for.
- Revenue & Scale: Global networks with hundreds to thousands of staff.
- End-to-end services: Strategy, UX, design, engineering, analytics and martech integrations.
- Enterprise clients: Complex platforms, multi-market rollouts and compliance-heavy industries.
Quick reality check
Bigger agencies bring deep resources and expertise but also higher fees, longer timelines and heavier project governance. Small businesses and trades often need speed, affordability and easy updates more than enterprise processes.
The biggest web design companies (and what they specialise in)
Below are major global digital agencies and consultancies that dominate high-end web design and digital transformation projects.
Accenture Interactive
Services: Digital strategy, UX, enterprise web platforms, martech
Massive global reach, strong systems integration skills and deep consulting experience. Typically used by enterprises for transformation rather than small-site builds.
Deloitte Digital
Services: Strategy, design, engineering, CX, analytics
Combines consulting rigour with creative delivery. Ideal for organisations needing governance, compliance and deep analytics.
Publicis Sapient
Services: Digital product, web platforms, data & AI
Strong in product-led transformations and large-scale experiences. Suited for brands wanting integrated digital ecosystems.
IBM iX
Services: Enterprise platforms, AI-driven experiences
Enterprise-grade engineering with an emphasis on AI, integrations and performance at scale.
WPP (e.g., Ogilvy, VMLY&R)
Services: Creative-led design, marketing, brand experiences
Large creative networks that combine branding, advertising and web experience design for global campaigns.
R/GA & Huge
Services: Innovation, product design, web & app engineering
Known for design-driven digital products and campaigns. Often engaged for high-visibility brand experiences.
Takeaway: The largest agencies offer unmatched capabilities for enterprise transformation, but they come with higher costs, more stakeholders and longer delivery windows. Small and medium businesses should weigh needs carefully before choosing scale over speed.
