Why your current website is slowing your consultancy down
You wrote a strong article. It took you two hours. Then another 45 minutes to get it into WordPress, add the images, set the metadata, and fix the formatting. By the time it's live, your energy for the next piece is gone.
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.
Headless CMS platforms decouple your content from your presentation layer. You write once, you publish everywhere. Your article can flow to your website, your newsletter, your LinkedIn content pipeline, and your client portal, without rebuilding it each time.
For a consultancy where your expertise is the product, that kind of leverage is not a nice-to-have. It's a growth mechanism.
In 2026, three platforms dominate the conversation for professional services firms: Sanity, Contentful, and Prismic. Each one takes a fundamentally different approach, and the right choice depends on the size of your team, how much content you produce, and how much technical overhead you're willing to carry.
What does a headless CMS actually do for a consultancy?
A headless CMS stores your content in a structured, API-driven way, separate from how it's displayed. Instead of your content being locked inside a WordPress theme, it lives in a database that can feed any front-end: your website, an app, a newsletter tool, or a client portal.
For advisory firms specifically, 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 with 8 to 15 people spend more time managing their CMS than writing actual thought leadership. The right platform removes that friction entirely.
Sanity, Contentful or Prismic: which fits a consultancy best?
Let's break down each platform based on what actually matters for advisory firms with 5 to 25 employees.
Sanity: the most powerful, but not the simplest
Sanity positions itself as a "Content Operating System," and for good reason. It's not just a place to store articles. It's a platform where you can model your entire content operation, from case studies to team profiles to testimonials, and automate how that content is managed.
The standout feature for consultancies in 2026 is the Content Agent, Sanity's AI-powered automation layer. Here's a concrete example: if you have 150 case studies and want to restructure all of them from a "client + result" format to a "client + challenge + process + result" format, the Content Agent can do that in minutes. Manually, that's 30 to 40 hours of work.
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 one real downside: Sanity requires a developer who understands GROQ (its query language) and can configure custom content schemas. The setup investment is typically €2,000 to €4,000 one-time.
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," and that framing tells you everything you need to know about who it's built for. Think Nike. Think Spotify. Think organizations running content across five or more channels with dedicated content operations teams.
For consultancies, the headline features are impressive on paper: AI-driven personalization (showing different case studies to financial services readers versus manufacturing readers), omnichannel content delivery, and enterprise-grade compliance including ISO 27001, GDPR, and SOC 2 certifications.
But here's the practical reality. Contentful's Lite plan starts at €300/month, regardless of how many users you have. That's the minimum entry point. For a boutique advisory firm with 8 to 12 people, you're paying €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. Much of the criticism in smaller-team reviews centers on complexity and pricing.
Contentful only makes sense for your consultancy if you have more than 50 employees, are delivering content across five or more channels simultaneously, have enterprise clients with specific compliance requirements, and have a monthly budget of €300 or more specifically for CMS infrastructure.
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. No GROQ. No custom schema configuration. You open a browser, and within 30 minutes, your first article is live.
That's a real advantage if your biggest bottleneck is getting started, rather than scaling a complex content operation.
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: helps your thought leadership content surface in search results
- Role-based permissions: set up content authors, editors, and approvers without writing a single line of code
- Strong integrations with Next.js, Gatsby, and Nuxt.js
Prismic scores 4.3 out of 5 on G2 across 359 reviews, with most positive reviews coming from smaller agencies and service firms, which is closer to your context 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 tradeoff: Prismic is less flexible. Custom content types require workarounds. Content reuse across formats is more limited. And if your content operation grows significantly, you may hit the ceiling of what Prismic can do without heavy customization.
Prismic is the right choice if you have 5 to 15 people, want your team to manage content independently without relying on a developer, and want to start publishing thought leadership within days rather than weeks.
How do these platforms compare side by side?
Here's a direct comparison across the criteria that matter most for advisory firms:
Ease of use:
- Sanity: moderate, requires initial setup and GROQ familiarity
- Contentful: high once configured, but configuration is complex
- Prismic: highest, intuitive UI with minimal technical knowledge required
Flexibility:
- Sanity: very high, fully customizable content schemas
- Contentful: high, but geared toward enterprise use cases
- Prismic: moderate, limited to predefined content structures
AI and automation:
- Sanity: excellent, Content Agent handles bulk transformations and tagging
- Contentful: good, personalization features for multi-audience delivery
- Prismic: basic, focused on SEO visibility assistance
Minimum monthly cost:
- Sanity: €0 (free plan covers up to 20 users)
- Contentful: €300 (minimum paid plan)
- Prismic: €45 (Starter plan)
Cost for 8 users:
- Sanity: €120/month on Growth plan
- Contentful: €300/month minimum regardless
- Prismic: €100/month (project-based, not per-user)
Developer dependency:
- Sanity: high, GROQ and custom schema setup required
- Contentful: high, complex initial configuration
- Prismic: low, most tasks manageable without developer involvement
Which headless CMS should a consultancy actually choose?
The answer depends on where your firm is right now, not where you want to be in five years.
Choose Sanity if your firm has 15 to 25 people, you produce significant volumes of content, you want AI automation to reduce the manual overhead on your team, and you have either an in-house developer or a web partner who can handle the setup. The free plan is genuinely usable, and the Content Agent alone can save your team dozens of hours per quarter.
Choose Prismic if your firm has 5 to 15 people, your primary goal is getting your consultants publishing thought leadership without technical friction, and you want to keep costs under €150/month. The speed to first publish is unmatched, and the intuitive editor means your team won't need training to use it.
Avoid Contentful unless you're running a larger operation with genuine omnichannel needs and an enterprise compliance requirement. For boutique advisory firms, the pricing structure makes it hard to justify.
One thing we consistently see at Luniq: the platform decision matters far less than the content strategy behind it. A consultancy with a clear positioning, a defined niche, and a publishing rhythm of two to three pieces per month will outperform a competitor with a more sophisticated CMS and no editorial discipline.
The CMS is infrastructure. Your expertise and consistency are the actual differentiators.
How your website connects to all of this
A headless CMS is only as effective as the website it feeds. If your site doesn't clearly communicate your niche, your methodology, and why a potential client should choose you over a larger firm, no amount of published content will close that gap.
This is exactly the challenge most boutique advisory firms face: the positioning isn't sharp enough to direct word-of-mouth, and the website doesn't do the work of communicating depth when a potential client lands on it.
If you're evaluating a CMS upgrade as part of a broader repositioning effort, it's worth starting with the website strategy first. The CMS choice should follow from your content model, not the other way around.
At Luniq, we work specifically with advisory firms and consultancies to build strategy-led websites that strengthen perceived authority and support consistent thought leadership. If you're ready to make your expertise visible beyond your immediate network, our Launched solution for consultancy and advisory firms is designed exactly for this.
Or if you already have a site and want to understand what's holding it back, start with a website audit before committing to a CMS migration.
