Web design agency for B2B websites

Where established B2B platforms
reach their limits

In marketing

The website was launched years ago, and the company has evolved several times since then. The content is maintained, but the architecture no longer holds. New target groups, new business areas, and new locations are forced into structures that were never designed for them.

In IT processes

The CMS has grown, not been planned. Plugins pile up, updates are risky, and interfaces to HubSpot, Salesforce, or industry systems have been cobbled together manually. Security and performance can no longer be managed reliably.

For decision-makers

The website no longer represents the company at the level at which it operates. Customers, applicants, and investors see a presence that falls short of the real standard.

Machine view

The content is decorative, not structured. AI systems cannot reliably read it—your company is underrepresented in generative answers or not mentioned at all.

How we develop platforms

  • Information architecture before design. We structure content before we design it—so editorial, IT, and management all understand together what information goes where, and why.
  • Modular design system instead of page templates. Components instead of pages—so your team can add new locations, products, or areas without the system breaking.
  • WordPress Enterprise as a platform. Scalable, with enterprise support and the Gutenberg editor—so your editorial team can work without developers.
  • API integrations instead of duplicate data maintenance. Integration with HubSpot, Salesforce, onOffice, job interfaces, and industry-specific systems—so data is maintained where it belongs and appears on the web automatically.
  • Machine readability as an architectural decision. Structured content, semantic markup, Schema.org—so AI systems understand your platform and classify your company correctly in generative answers.
  • Editorial self-management by default. Defined Gutenberg components, standardised page types, clear maintenance paths—so after launch the platform is a system that guides your team, not a project the agency has to keep running.

What is included in the engagement

Strategy & information architecture

Target-group logic, page types, URL structure, conversion journeys—as a maintainable architecture, not a PowerPoint.

UX & UI design

Modular design system, component library, responsive layouts, documented corporate design manual.

Frontend & web development

WordPress Enterprise on the Sage framework with Gutenberg, custom components, performance-optimised, GDPR-compliant.

API Integrations

Integration with CRM, marketing automation, industry systems (onOffice, ERP, job interfaces) as technical interfaces with documented data flow.

Login areas and portals

Protected areas for owners, specialist dealers, and customers—including a permissions and roles concept.

Accessibility (WCAG)

Compliance for public-sector organisations, housing providers, and companies with compliance requirements.

Design system transfer

Transfer to print, annual reports, and internal communications—so the system holds up beyond the website.

Hosting, performance, GDPR

Scalable hosting, technical maintenance, compliance setup.

Continuous Improvement

Ongoing development instead of project end. The platform grows with the company.

This is how your
new company platform is created

The stack behind the platform system

WordPress Enterprise

WordPress Enterprise on the Sage framework with a custom-developed theme → your team works with a market standard for which you can always find developers.

Gutenberg Block Editor

Gutenberg Block Editor with custom components → the editorial team builds pages visually, without shortcodes or plugin sprawl.

REST APIs

REST APIs for structured data flows

CRM, marketing automation, and industry systems work as one system, not in parallel. Documented for “WordPress and HubSpot” and “WordPress and Salesforce”

Schema.org markup

Schema.org markup and semantic structuring → content becomes not only readable for AI systems, but recognisable as entities—people, products, cases, locations with clear relationships to one another.

WCAG compliance

WCAG compliance

as an architectural decision, not a retrofit. Accessibility is part of the platform, not an add-on feature.

Scalable hosting, GDPR-compliant

Scalable hosting, GDPR-compliant

IT gets a transparent infrastructure, not a black-box setup.

What AI-first means in platform architecture

For us as a WordPress agency, AI is an architectural principle—not just a feature. The foundation layer—CMS, data modelling, interfaces—forms the basis for the intelligence layer: machine-readable content and semantic preparation for AI visibility. Content is structured so that it can be processed equally well by classic browsers, search engines, and generative AI systems. Anyone who wants to build a RAG knowledge layer (Retrieval Augmented Generation) on this foundation will find it in DialogHub—in productive use at KAMPMEYER and at Lernstudio Barbarossa.

When industry systems and the website become one system

B2B companies typically work with established stacks: HubSpot or Salesforce in CRM, marketing automation, job interfaces, industry-specific systems. A new platform must fit this reality, not run alongside it. The same principle applies to all: data maintenance remains in the source system; the website consumes it.

For real estate agents

WordPress + onOffice: properties, marketing status, owner data

For education providers

WordPress + internal CRM: multi-location, course management, dates, contacts

B2B & industry

WordPress + ERP/specialist dealer systems: product data, protected login areas

What you may be asking yourself right now

Which CMS do you recommend for B2B companies?

WordPress Enterprise—scalable, with enterprise support, independently maintainable, with clear migration paths to headless architectures when the business model requires it. For specific requirements (HubSpot-centred marketing stacks, headless setups), we offer HubSpot CMS and Payload as alternatives.

How does integration with our existing stack work?

Via REST APIs to established systems: HubSpot, Salesforce, onOffice, job interfaces, industry-specific ERPs. Data maintenance remains in the source system; the website consumes the data and updates automatically. Duplicate maintenance is avoided.

How much of the platform can our team manage independently?

Everything that is editorially relevant. This is the default, not the exception. Modular Gutenberg components, standardized page types, documented maintenance workflows – your team works without developer access. At Lernstudio Barbarossa, multiple editorial teams maintain 165 locations via one platform.

What happens to our old website during the project?

It continues to run. Migration and relaunch are planned as a controlled transition—not as a fixed cutover date with risk. The URL structure, existing SEO equity, and content are taken into account during the architecture phase.

What does platform development with 360VIER cost?

Flat-rate answers are not credible. The orientation and concept phase (4–6 weeks) delivers a clear scope, an architectural decision, and a roadmap—this is the basis for a reliable effort estimate. Not before.

Do you operate nationwide or only regionally?

Nationwide and internationally (DE, CH, AT). 360VIER works remote-first with documented processes. For in-person appointments, we will come to you on-site.
