Bolt-On vs Custom Build: Two Ways to Deploy AI Across Your Client Book
One solution deployed to many clients, or a bespoke build for one. Most agencies need both.
Fountainhead operates two deployment models. Understanding the difference is important because the economics, timelines, and selling approaches are completely different.
A bolt-on deployment takes a single proven solution and deploys it across multiple clients with minimal customisation. Each client gets their own instance, configured for their business, but the core platform is the same. Think of it like deploying the same kitchen design across 20 restaurants, with different menus and branding in each.
Examples: an AI customer service widget deployed across 15 hospitality clients. A reviews management system rolled out to every trades client in your book. An instant quoting tool deployed to 8 professional services firms. Same platform, different configurations.
The economics of bolt-on are compelling. Setup is fast (days per client, not weeks). Wholesale cost is lower because the platform is already built. The agency can roll it into existing retainers as a value-add or charge a standalone monthly fee. At $500-$800 per client per month across 10 clients, that is $60K-$96K in annual recurring revenue from one solution.
A custom build is bespoke. It is built specifically for one client's unique operational problem. A full loyalty and payments platform for a hospitality group. A complete operations management system for a roastery. A voice ordering system for a cafe chain. These are larger engagements, higher value, and longer to deliver.
Custom build economics: wholesale project fees of $15K-$60K plus ongoing infrastructure. The agency charges $30K-$120K retail. Timelines are 4-12 weeks. The margin per project is higher, but the volume is lower.
Most agency partners end up using both models. Bolt-on provides the volume and recurring revenue base. Custom builds provide the high-value anchor projects that demonstrate deeper capability. The Partner Playbook maps client signals to the right deployment model, so your team knows which approach to recommend before the scoping conversation starts.
Your expertise deserves a custom build.
The 12 Principals programme is the bespoke version applied to you: a twelve month build that turns your methodology into an app, a CRM, and a positioning engine you own outright.
