Lock-In Is Dead.
Here's What Replaces It.

The digital signage industry has spent two decades building moats from switching costs. AI and open protocols are draining them.

"The vendor's incentive shifts from earning your business to maintaining your captivity. AI changes this equation permanently."

The Business Model

How the Industry Actually Works

The digital signage business model is elegant in its simplicity and ruthless in its execution. Vendors charge per-screen, per-month. The more screens you deploy, the more you pay. But the real revenue isn't the subscription — it's the switching costs.

Once an organization has configured 50 screens, built a content library, trained staff on a specific dashboard, and integrated signage into their daily workflows, they're locked in. Not because the product is good. Because leaving is too expensive.

Every major player knows this. BrightSign sells proprietary hardware that only works with their software. Yodeck and ScreenCloud lock your content into proprietary formats. Most vendors make it trivially easy to import content and deliberately difficult to export it.

The industry's retention rate isn't a testament to product quality. It's a testament to the cost of migration.

The Mechanisms

What Lock-In Actually Looks Like

Lock-in isn't one thing. It's a system of interlocking constraints:

  • • Proprietary hardware: Buy our player, or nothing works. BrightSign's entire model depends on this.
  • • Proprietary formats: Your presentations, templates, and content exist in a format only one vendor can read.
  • • Per-screen pricing: The cost to stay scales linearly, but the cost to leave scales exponentially — rebuild everything, retrain everyone, reconnect everything.
  • • No export: Try getting your full configuration out of any major signage platform. Screen assignments, group structures, schedules, content — good luck.
  • • Multi-year contracts: Lock in the lock-in with contractual obligations.
  • • Training dependency: Staff knows one dashboard. Switching means retraining everyone.

The Disruption

AI Breaks the Lock

This is where it gets interesting.

Model Context Protocol and similar standards mean AI assistants can now interact with external systems through structured, documented interfaces. When a digital signage platform exposes its full operational surface through MCP — screens, content, groups, schedules, alerts, hardware — something fundamental changes.

An AI agent that can read your entire signage configuration from Platform A can understand your content structure, your screen assignments, your scheduling logic, your group hierarchy. And if Platform B also exposes its operational surface through MCP, that same AI agent can rebuild your configuration on Platform B.

Migration stops being a six-month project with a dedicated team. It becomes a conversation.

Read my current setup from CastHub. Now create the equivalent configuration on [other platform].

This doesn't just reduce switching costs. It eliminates the business model that depends on them.

Discuss this shift on r/digitalsignage, r/selfhosted, or r/sysadmin. See the MCP specification on GitHub.

Our Bet

CastHub's Position

CastHub MCP is building for the world where lock-in doesn't work anymore. This is a deliberate choice, not a marketing position.

  • • Flat-rate pricing: $12/mo (Basic), $35/mo (Pro), $95/mo (Enterprise, unlimited screens). Your cost doesn't scale with your success. See pricing.
  • • Open protocols: MCP for AI control, OpenAPI for programmatic access. Your configuration is readable and portable.
  • • Standard hardware: Amazon Signage Stick — $35 hardware that Amazon designed and documents publicly. Not proprietary. Not locked to CastHub.
  • • Governance, not gatekeeping: Our governance layer (preview-before-confirm on writes, with ReadOnly/Destructive/Idempotent risk annotations) protects you from mistakes. It doesn't protect us from competition.

We compete on product quality. Not on the cost of leaving.

The Principles

What Open Signage Means in Practice

Open Signage is a set of principles, not a specification:

  1. 1. Standard protocols: MCP, OpenAPI, documented APIs. No proprietary interfaces required.
  2. 2. Data portability: Your screen configuration, content assignments, schedules, and group structures are exportable and readable.
  3. 3. Hardware interoperability: Amazon built an open hardware API. CastHub built an open software API. Together, they create a fully AI-controllable signage stack through documented protocols.
  4. 4. No proprietary hardware: Works with Amazon Signage Stick, Fire TV, Apple TV, Android TV, Samsung Tizen, LG WebOS, Windows, and any browser.
  5. 5. Flat-rate pricing: Your cost to stay is the same whether you have 2 screens or 200. No per-screen tax.
  6. 6. Governance as trust: Preview-before-confirm on writes, with risk-level annotations, protects operations rather than vendor relationships.

Start with CastHub. Stay because you want to.

No lock-in. No per-screen pricing. No proprietary hardware. Just signage that works — controlled by the tools you already use.
