Why your current website is slowing your consultancy down
You wrote a strong article in two hours. Then you spent another 45 minutes getting it into WordPress: adding the images, setting the metadata, fixing the formatting. By the time it's live, you have no energy left for the next piece.
This is the hidden cost of monolithic CMS platforms, and it's one of the biggest reasons boutique advisory firms struggle to build consistent visibility outside their immediate network.
A headless CMS separates your content from the way it is displayed. You write an article once and publish it to your website, newsletter, LinkedIn content pipeline and client portal, without rebuilding it each time.
When your expertise is the product, that reuse puts more of it in front of clients for the same writing time.
In 2026, three platforms come up most for professional services firms: Sanity, Contentful and Prismic. Each takes a different approach. The right choice depends on your team size, how much content you produce and how much technical overhead you're willing to carry.
What does a headless CMS do for a consultancy?
A headless CMS stores your content in a structured database, separate from how it's displayed, and serves it through an API. That database can feed any front end: your website, an app, a newsletter tool or a client portal. In WordPress, the same content stays locked inside a theme.
For advisory firms, this matters for three reasons:
- Content reuse: One case study can automatically populate your website, a PDF template, and a LinkedIn post format, without rebuilding each time
- Team workflows: Multiple consultants can contribute content simultaneously, with approval workflows, without version conflicts
- Long-term scalability: Your content infrastructure grows with your firm, rather than requiring a €15,000-€35,000 migration every three years
We've seen consultancies of 8 to 15 people spend more time managing their CMS than writing. The right platform takes most of that work away.
Sanity, Contentful or Prismic: which fits a consultancy best?
Here is how each platform scores on what matters to advisory firms with 5 to 25 employees.
Sanity: the most powerful, with the most setup
Sanity calls itself a "Content Operating System", and the label fits. You can model your whole content operation in it, from case studies to team profiles and testimonials, and automate how that content is managed.
For consultancies, the standout feature in 2026 is the Content Agent, Sanity's AI automation layer. Say you have 150 case studies and want to restructure them all from a "client + result" format to "client + challenge + process + result". The Content Agent does that in minutes. By hand, it takes 30 to 40 hours.
Sanity also supports real-time collaboration, so multiple consultants can work on the same piece simultaneously without version conflicts.
On G2 as of early 2026, Sanity holds a 4.7 out of 5 rating across 900+ reviews, the highest of the three platforms compared here.
Pricing is structured as follows:
- Free plan: up to 20 users, 2 datasets, Content Agent included, at €0/month
- Growth plan: €15 per user per month, with AI Assist and scheduled drafts
- Enterprise: custom pricing with SSO, dedicated support, and SLAs
For a consultancy with 8 people on the platform, that's roughly €120/month on the Growth plan. The main downside: Sanity needs a developer who knows GROQ (its query language) and can configure custom content schemas. That setup typically costs €2,000 to €4,000, once. Luniq builds Sanity websites for B2B firms and handles that setup for you.
Sanity is the right choice if you produce more than 10 pieces of content per month, want AI-driven automation to reduce your team's workload, and are willing to invest in proper technical setup upfront.
Contentful: enterprise power at enterprise prices
Contentful calls itself a "Digital Experience Platform", which tells you who it's built for: companies like Nike and Spotify, running content across five or more channels with dedicated content operations teams.
On paper, the headline features look strong for consultancies: AI-driven personalisation (different case studies for financial services readers and manufacturing readers), omnichannel content delivery, and enterprise-grade compliance including ISO 27001, GDPR and SOC 2 certifications.
In practice, Contentful's Lite plan starts at €300/month, however many users you have. For a boutique advisory firm with 8 to 12 people, that's €300/month for features you'll use 20% of.
Contentful also scores lower than Sanity on G2, at 4.2 out of 5 stars across 318 reviews. Reviews from smaller teams mostly criticise its complexity and pricing.
Contentful only makes sense for your consultancy if you have more than 50 employees, deliver content across five or more channels at once, have enterprise clients with specific compliance requirements, and can spend €300 or more a month on CMS infrastructure alone.
For most advisory firms with 5 to 25 people, Contentful is financial overkill.
Prismic: the fastest way to start publishing
Prismic takes the opposite approach from Sanity. You skip GROQ and custom schema configuration: you open a browser, and your first article can be live within 30 minutes.
That helps most when getting started is your bottleneck.
Key strengths for consultancies:
- Side-by-side live preview: you see exactly how your article looks as you write it, no developer needed to check formatting
- Built-in AI search visibility tools: help your thought leadership content surface in search results
- Role-based permissions: set up content authors, editors and approvers without writing code
- Strong integrations with Next.js, Gatsby, and Nuxt.js
Prismic scores 4.3 out of 5 on G2 across 359 reviews. Most positive reviews come from smaller agencies and service firms, which is closer to a consultancy's situation than the enterprise reviews that dominate Contentful's profile.
Pricing is project-based rather than per-user:
- Free: limited features
- Starter: approximately €45/month for one project and 25,000 API calls
- Growth: approximately €100/month for three projects and 200,000 API calls
The trade-off: Prismic is less flexible. Custom content types need workarounds, and reusing content across formats is harder. If your content operation grows a lot, you may hit the limit of what Prismic can do without heavy customisation.
Prismic is the right choice if you have 5 to 15 people, want your team to manage content without a developer, and want to publish your first thought leadership within days.
