What Does Building It Yourself Really Cost?

Build an editable planning scenario from your team size, salary assumption, and required domains. Results are directional estimates, not verified savings, a proposal, or a delivery commitment.

Services You Need to Build

Select the domains your team would need to build from scratch. The month values are editable-model assumptions for early planning; validate them against your own architecture and scope.

Calculator Assumptions

  • Build months are planning assumptions, not measured Launch Rail customer benchmarks
  • The model adds 30% for benefits, tooling, cloud infrastructure, and coordination
  • The model applies a 60% parallelism factor across the selected team size
  • The model estimates annual maintenance at 20% of initial build cost
  • The $4,800 figure is the published design-partner pilot, credited toward a quote-based final license
  • Final license, customer cloud, migration, operations, and custom engineering costs are not included
Beyond the Numbers

What the Calculator Cannot Quantify

The real cost of building in-house goes far beyond salaries.

Time to Market

  • Foundation work competes with differentiated product work
  • Integration and operating effort should be included in planning
  • A guided pilot validates the documented Launch Rail path
  • Your team decides where ownership creates the most leverage

Ongoing Opportunity Cost

  • Senior engineers maintaining CRUD vs. building differentiators
  • On-call rotations for infrastructure you don't own
  • Security patches, dependency upgrades, breaking changes
  • Knowledge silos when engineers leave

Strategic Leverage

  • Licensed source can be inspected and extended within the agreement
  • Service boundaries support independent capacity planning
  • Security responsibilities and evidence are explicit in the Trust Center
  • A blueprint makes dependencies and deployment work visible

Stop Building Infrastructure. Start Shipping Product.

This model is a conversation starter. Bring the assumptions to an architecture review and we will map the available modules, implementation scope, final license basis, and customer-cloud responsibilities.
