For Transformation Leaders: replatform without a big bang
ReactorCX is the enterprise loyalty platform that large organizations move to without a big-bang cutover. Vision Alignment names every system and feed before a platform is chosen. ThreadSync runs the build as parallel workstreams with a "done when" test for each. SafeSwitch proves the new platform against full production traffic and cuts over only when both systems agree.
The assessment produces a plan with gates, threads and a cutover approach for your steering committee.
"How do we replace the platform without a big-bang cutover?"
By proving the new platform against production before members ever touch it, and by running the work as threads with gates instead of phases with hope.
Vision Alignment
Every system, feed, integration point and owner named. Decision rights and cadence fixed.
ThreadSync
Parallel threads: program rules, data, integrations, finance, member care, change management. Each has a done-when test.
SafeSwitch parallel run
ReactorCX processes mirrored production traffic; outcomes reconciled across the full member base.
Gated cutover
Traffic moves by gate. Rollback armed. Legacy stays live until you confirm.

Gates, not milestones
Parity across the member base, explained differences, proven headroom, armed rollback. A gate is passed on evidence, never on a status slide.
Threads, not phases
One specialist team per domain. The timeline is the longest thread, not the sum of sequential phases.
Your experts scheduled, not consumed
Vision Alignment fixes what the customer supplies and when, so scarce internal owners are not lost to months of workshops.
Change management funded
Training for business users, developers, SQL, API and the data model is a thread with a budget, not an afterthought.
Sequencing against in-flight programs
ReactorCX integrates with both the legacy and the target point of sale during a multi-year window, so loyalty does not block the POS or CDP program.
One accountable team
Loyalty Methods builds, delivers and operates ReactorCX. Integration outcomes are owned, not disputed with the integrator.

How this is measured
Sum of member records moved from a legacy platform onto ReactorCX in SafeSwitch cutovers; excludes greenfield programs. As of 2026-Q3.
How this is measured
Number of SafeSwitch production cutovers completed and the number completed with zero member-visible downtime. As of 2026-Q3.
How this is measured
Elapsed time from ThreadSync Vision Alignment kickoff to production cutover across completed enterprise implementations. As of 2026-Q3.
How this is measured
Historical transaction records loaded into ReactorCX and reconciled against legacy outputs during SafeSwitch migrations. As of 2026-Q3.

Questions transformation leaders ask
What does a realistic timeline look like for a program our size?
ReactorCX implementations have run from three to eighteen months; scope sets the duration. ThreadSync runs domains as parallel threads with a "done when" test each, and SafeSwitch adds a parallel-run period before cutover whose length is set by the reconciliation results, not the calendar.
What are the gate criteria for cutover?
Parity between legacy and ReactorCX outcomes across the full member base, explained and resolved differences, proven headroom under replayed load, and a rollback path that stays armed after traffic moves. The legacy system stays live until you confirm.
How does Loyalty Methods work with system integrators?
Vision Alignment names every system, feed and integration point and its owner, including the integrator's scope, before the platform is chosen. Loyalty Methods owns platform, integration and migration outcomes rather than disputing them, and delivery leadership joins early.
