Sanity isn’t just a CMS — It’s the New Business Operating System

Inside our plan to replace 15+ business apps and build our own ERP with Sanity

December 19, 2025

I’ve been building things on the internet for more than 20 years now.

In my early career, I built everything from education tech to custom ERPs that still make me smile and proud when I think about them.

Then in 2009, I started Multidots, and our world expanded dramatically.

We began helping Fortune 500 companies and billion-dollar brands build their content management systems and scalable digital experiences using modern tech-stacks.

Over the years, our clients’ needs evolved. They didn’t just want a CMS anymore. Their digital ecosystems were turning into complex organisms — dozens of internal tools, external apps, micro-services, workflows, and integrations that all needed to talk to each other.

Content stopped being “what the website says.”

Content became the operating system for the business.

And that’s where my story with headless begins.

Why I Was Never a Big Fan of Headless

We’ve built plenty of headless applications over the years, and I’ll be honest:

I was never a big fan.

Not because headless is bad — it has real advantages — but because the way most teams were using it resulted in:

  • Over-engineered setups
  • overly structured content
  • Maintenance nightmares
  • Slow delivery cycles
  • Costly infrastructure
  • Poor real-world benefits

So whenever a client asked, “Should we go headless?” my message was always:

Choose headless only when it solves a real business challenge — not because it’s trendy.

But around 2023, that perspective changed.

I was searching for a modern platform that supported:

  • High-performance websites
  • Secure, scalable data
  • Custom internal apps
  • Real-time collaboration
  • Flexible modeling
  • AI workflows and automation

This is when I stumbled across Sanity.

And I couldn’t look away.

The Moment Sanity Caught My Attention

I spent nearly a month diving deep:

  • Reading the documentation
  • Talking to Sanity engineers
  • Attending Sanity events
  • Testing prototypes
  • Building demo apps
  • Experimenting with real client work

Somewhere along this journey, I had a moment of clarity:

Sanity isn’t a CMS.
Sanity isn’t even just a content operating system.
Sanity is a full-fledged Business Operating System.

Here’s exactly why.

The Core Building Blocks of Sanity

To understand why Sanity is great to build business apps, you need to understand its foundational architecture.

1. Sanity Studio

This is the “backend” where everything comes together.

  • Fully customizable environment
  • Build custom apps directly inside the Studio
  • App SDK lets developers create any internal tool imaginable
  • Agents & Actions bring AI directly into workflows
  • Studio becomes the UI for your entire business

Studio is not like a CMS admin panel — it’s a platform.

2. Content Lake

This is Sanity’s data layer — the beating heart of the entire system.

  • Stores all structured and unstructured data
  • Handles massive volumes (hundreds of millions of documents)
  • Optimized for fast read/write operations
  • Real-time content updates across all apps

Think of this as your company’s single source of truth.

3. Flexible, Modern Data Modeling

Sanity feels like building on a modern database:

  • Schema-based
  • Completely flexible
  • No rigid CMS constraints
  • Perfect for complex, interconnected business systems

You’re not forced into “posts,” “pages,” or “custom fields” anymore.

You can model your business accurately.

4. GROQ: The Query Engine

Sanity’s query language is one of its superpowers.

  • Ultra-fast
  • Easy to write
  • Retrieve exactly the data you need
  • Power real-time UI updates
  • Enables high-performance apps

It’s like SQL and GraphQL had a child that loves developers.

5. Scalability & Performance

Sanity was built for enterprise scale:

  • ~250 million datasets handled comfortably
  • Built for teams that expect to grow
  • Works with any modern frontend (Next.js, React, Angular, Vue, etc.)
  • Architected as a global API-first platform

This is infrastructure that grows with your business — not against it.

Why Sanity Is Perfect for a Business Operating System

Now that we understand the building blocks, here’s why Sanity becomes a BOS.

1. A Unified Technical Architecture

In a Business OS, you need:

  • A powerful backend → Sanity Studio
  • A scalable database → Content Lake
  • A flexible schema system → Schemas
  • A lightning-fast query engine → GROQ
  • Integration hooks → Webhooks, APIs
  • AI automation → Agents & Actions

With Sanity, you get it all in one place.

2. Developers Can Build True “Apps” using Sanity Clients + App SDK

Real apps — not plugins.

You can build:

  • Recruitment portals
  • CRM systems
  • Task and delivery boards
  • Dashboards
  • AI-powered tools
  • Internal workflows
  • Time tracking systems
  • HR automations
  • Approval flows

And they all live inside ONE unified experience — the Studio.

3. AI-Enabled Workflows with Agents & Actions

This is the future.

With AI inside Sanity, you can:

  • Automate repetitive tasks
  • Enrich data
  • Generate structured content
  • Validate submissions
  • Improve quality
  • Add intelligent decision-making
  • Support teams with internal AI copilots

Sanity becomes AI-native, not “AI patched on top.”

Building a Modern BOS on Sanity

Now, let me explain why I’m genuinely bullish on Sanity and why I believe it’s one of the best platforms to build modern micro-ERPs and business operating systems.

1. What a Business Operating System Includes

Most companies rely on tools for:

  • HR
  • Recruiting
  • Finance
  • Accounting
  • Legal
  • Support
  • Delivery / fulfillment
  • Sales & CRM
  • Marketing
  • Analytics
  • Executive dashboards

These are usually spread across separate, disconnected platforms.

2. The Problem With Today’s Small Business Tech Stacks

Most companies use 20–40 SaaS tools:

  • Too many siloed apps
  • No unified data model
  • Poor cross-team visibility
  • Expensive monthly subscriptions
  • Limited customization
  • Constant switching fatigue

No one knows what's happening across the organization because the data lives everywhere — except together.

3. How Sanity Solves This

With Sanity, you can build a centralized BOS where:

  • Every team’s data lives in one unified Content Lake
  • Internal tools share the same database
  • Frontend apps and dashboards are decoupled but connected
  • You build custom tools tailored to your exact workflow
  • AI automates operations across the business

This gives you what no SaaS stack can:

A system built exactly for your business — not someone else’s.

4. Examples of What You Can Build on Sanity

These are real BOS components you can build inside the Studio.

HR

Finance

Support

Production / Delivery

Leadership

  • Recruitment portal
  • Employee management
  • Onboarding workflows
  • Compliance tracking
  • Accounting dashboards
  • Expense management
  • Vendor management
  • Approval workflows
  • Ticketing system
  • Knowledge base
  • Customer performance dashboards
  • Project management
  • Delivery workflows
  • Resource allocation dashboards
  • BI dashboards
  • KPI reporting
  • Forecasting tools (AI-powered)

Sanity lets you connect all these tools under one roof.

Building Our Own mini ERP on Sanity

At Multidots, we’ve started building our own business operating systems inside Sanity.

We currently use over 15+ different tools across different teams.

We’ve already replaced 3 of our internal tools in just 1.5 months using Sanity + some vibe code.

  1. Ghost (Newsletter) → 4 weeks
  2. Screaming Frog (QA) → 3 weeks
  3. Harvest (Time Tracking) → 7 weeks

Our long-term vision:

Instead of managing dozens of SaaS tools, we’re building a micro ERP on Sanity to run our agency.

This is why I truly believe:

Sanity is not just a CMS.

Not just a Content OS.

But a Business Operating System.
